Commercial Glasswasher Error Codes

Error Code on Your Glasswasher? Find Out What the Machine Is Trying to Tell You.

You're halfway through service.

The glasswasher stops.

A code appears on the display.

Someone turns the machine off and back on.

The code disappears.

Then it comes back.

Now the question isn't just:

"What does this error code mean?"

It's:

"What is actually causing it?"

Commercial glasswasher error codes can provide valuable diagnostic information, but they don't always identify the exact component that needs replacing.

A drainage error, for example, tells us the machine hasn't drained as expected.

It doesn't automatically tell us:

"Replace the drain pump."

Worldwide CDM diagnoses commercial glasswasher error codes and operating faults across Sydney.

With more than 30 years of commercial catering equipment experience, we use the manufacturer's error information as a starting point, investigate the system behind the code and identify the underlying cause.

Find the Cause. Fix What Matters.

What Does a Commercial Glasswasher Error Code Mean?

Modern electronically controlled commercial glasswashers can monitor different conditions throughout the operating cycle.

Depending on the machine, faults may relate to:

  • Filling

  • Water level

  • Rinsing

  • Heating

  • Temperature

  • Draining

  • Pumps

  • Door position

  • Sensors and probes

  • Electrical systems

  • Electronic controls

  • Safety systems

When the controller detects an abnormal condition, it may display a code or warning.

The important distinction is:

An Error Code Tells You What the Machine Detected. It Doesn't Always Tell You Which Part Has Failed.

That's where proper diagnosis begins.

Are Commercial Glasswasher Error Codes Universal?

No.

This is important.

Error codes are manufacturer and model specific.

An error displayed on an Eswood Smartwash cannot automatically be interpreted using an error list for a Washtech, Sammic, Lamber or Norris machine.

Even different ranges from the same manufacturer may use different controls and fault systems.

For example, current Washtech professional machines can use electronic touchscreen controls with immediate fault diagnosis, while current Sammic glasswasher ranges use electronic control panels, with the exact features differing by model.

Always identify:

Manufacturer

Model

Complete error code

before deciding what the fault means.

Real Eswood Smartwash 400 & 500 Error Codes

Worldwide CDM works on Eswood commercial warewashing equipment, so this is a useful real-world example of how error-code diagnosis works.

The Eswood Smartwash 400 and Smartwash 500 operating manual confirms that these machines have an advanced electronic soft-pad control panel and self-diagnostic system.

The following codes are taken from the Smartwash 400/500 operating information.

Eswood Smartwash Er01 – Not Rinsing

Manufacturer fault description: Not rinsing.

The machine has detected that the rinsing cycle wasn't completed correctly. The operating information recommends checking that the rinse nozzles are clean.

What does Er01 mean in simple terms?

The glasswasher expected the rinse stage to operate correctly, but something in that process hasn't occurred as expected.

The rinse nozzles are an obvious starting point.

However, if the problem remains after normal operator cleaning, the complete rinse system may require diagnosis.

Don't Replace Parts Based on Er01 Alone.

First establish why the rinse isn't being completed correctly.

Eswood Smartwash Er02 – No Drainage

Manufacturer fault description: No drainage.

According to the Smartwash manual, Er02 indicates that the water wasn't drained or was drained incorrectly. Operator checks include looking for kinks in the drain pipe, blocked filters or siphon, and checking the overflow pipe has been removed before draining.

In simple terms:

The machine expected the water to leave.

It didn't happen correctly.

That does not automatically mean the drain pump has failed.

Possible areas requiring investigation can include:

  • Filters

  • Drain hose

  • Drain restriction

  • Site drainage

  • Drain pump

  • Electrical supply to the pump

  • Water-level detection

  • Control system

Eswood Smartwash Er03 – Rinse Temperature Reset Error

Manufacturer fault description: Rinse temperature reset error.

The Smartwash manual describes Er03 as the boiler temperature failing to reset within the set time during the wash cycle. Its operator instruction is to switch the machine off and on and run another cycle.

If the fault returns, further diagnosis may be required.

Why?

Because the code describes what the controller observed.

The underlying reason still needs to be established.

Relevant systems may include:

  • Boiler heating

  • Temperature sensing

  • Electrical controls

  • Related heating components

Eswood Smartwash Er04 – Wash Tank Not Filling to Level

Manufacturer fault description: Wash tank not filling to level.

For Er04, the Smartwash operating information directs the operator to check that the inlet pipes are correctly connected, the water tap is open and the overflow is correctly positioned in the drain, before restarting the machine.

In simple terms:

The machine expected the wash tank to reach its required water level.

It didn't.

Possible causes can extend beyond simply:

"There's no water."

Depending on diagnosis, relevant areas can include:

  • Water supply

  • Isolation valve

  • Inlet restriction

  • Inlet valve

  • Water-level system

  • Overflow position

  • Wiring

  • Electronic controls

Glasswasher not filling?

Troubleshoot Commercial Glasswasher Not Filling With Water →

Eswood Smartwash Er05 – Wash Tank Temperature Probe Open

Manufacturer fault description: Wash tank thermometer error — probe open.

The Smartwash manual explains that with Er05, the machine isn't reading the tank temperature value.

This is a good example of why error codes are useful.

The machine isn't simply saying:

"I'm not hot enough."

It's indicating:

"I'm not receiving the tank temperature information I expect."

The relevant diagnostic area may therefore involve the temperature-measuring circuit rather than immediately assuming the heating element has failed.

Possible areas requiring professional assessment can include:

  • Tank temperature probe

  • Connections

  • Wiring

  • Electronic input

  • Related control system

Eswood Smartwash Er06 – Wash Tank Temperature Probe Shorted

Manufacturer fault description: Wash tank thermometer error — probe shorted.

The Smartwash operating information identifies Er06 as a shorted wash-tank temperature probe condition.

This is different from Er05.

Both relate to tank-temperature measurement, but the self-diagnostic system is reporting different electrical conditions.

This is exactly why:

The Complete Error Code Matters.

Don't report:

"It's showing a temperature error."

Take a photo of the actual code.

Er05 and Er06 give the technician more specific diagnostic information.

Eswood Smartwash Er07 – Boiler Temperature Probe Open

Manufacturer fault description: Boiler thermometer error — probe open.

According to the Smartwash manual, Er07 means the machine isn't measuring the boiler temperature.

Again, this should not automatically be interpreted as:

"The boiler isn't heating."

The boiler could potentially be a different issue from the machine's ability to correctly measure boiler temperature.

Diagnosis may therefore need to distinguish between:

Actual temperature

and

Temperature information received by the controller.

Eswood Smartwash Er08 – Boiler Temperature Probe Shorted

Manufacturer fault description: Boiler thermometer error — probe shorted.

The Smartwash manual identifies Er08 as the corresponding shorted-probe condition for boiler temperature measurement.

If the error returns after the manufacturer's normal restart procedure, arrange professional assessment rather than repeatedly resetting the machine.

Eswood Smartwash ErSF – Electromechanical Safety

This is an important one.

The Smartwash operating information identifies ErSF as an electromechanical safety condition involving boiler/tank temperature or wash-tank level being outside safe values, with the electromechanical safety having operated. The manual directs the user to contact an authorised service technician.

Earlier in the operating instructions, Eswood also states that if rinse water doesn't reach its factory-set safe temperature during the wash cycle, the cycle is prolonged; if the rinse temperature still doesn't reach the required level, ErSF is displayed.

If ErSF appears:

Don't treat it as a nuisance message that simply needs clearing.

The machine is reporting a safety-related operating condition.

Find Out Why the Safety System Operated.

These descriptions apply specifically to the Eswood Smartwash 400/500 documentation referenced here and shouldn't be applied automatically to other Eswood models or other brands.

Is "door" an Eswood Smartwash Error Code?

This is another distinction worth making.

On the Smartwash 400/500, the display can show operational messages as well as actual error codes.

The Smartwash manual identifies:

door = door open

It also identifies display messages including:

End = end of cycle

AS = automatic start enabled

dr = final drain

and program indicators such as Pr 1, Pr 2 and Pr 3.

So:

Not Everything on the Display Is an Error Code.

This is another reason to understand the machine before diagnosing it.

Door message won't clear?

What About Lamber, Sammic, Washtech and Norris Error Codes?

Worldwide CDM also works with other commercial glasswasher brands.

But we don't believe in publishing an error code against a machine unless we can confidently match it to the appropriate manufacturer and model.

Different control systems are used across commercial glasswashers.

For example, Washtech currently provides separate operating manuals and operator-use documentation across individual models including GE, GL, GM, UD, XG and others.

Sammic likewise provides model-specific documentation through its support system, and its current glasswasher range uses electronic controls with different features according to model.

Even machines that don't present faults in the same way can provide useful troubleshooting information. The Norris Glassmate manual, for example, provides its own model-specific troubleshooting guide and operating requirements.

That's why our approach is:

Identify the Machine. Verify the Code. Diagnose the Cause.

Why We Don't Publish a Generic List of Every Glasswasher Error Code

It might look impressive.

But it wouldn't necessarily be useful.

Worse, it could be misleading.

Imagine someone searches:

"Glasswasher error 04."

They find a random table saying:

Heating problem.

But their specific machine uses that code for something completely different.

Now they're troubleshooting the wrong system.

Worldwide CDM's approach is different.

Brand → Model → Exact Code → Manufacturer Meaning → Diagnosis

That's more useful than guessing.

And it reflects how we approach repairs.

Find the Cause. Fix What Matters.

Does an Error Code Tell You Which Part to Replace?

Usually, you shouldn't make that assumption.

Consider the verified Eswood Smartwash Er02 drainage fault.

The machine knows the water hasn't drained correctly.

But the cause could potentially relate to several things within the drainage process.

The error doesn't automatically say:

"The drain pump motor has failed."

Similarly, Er04 tells us the tank hasn't filled to the expected level.

That doesn't automatically mean:

"Replace the inlet valve."

The water supply, overflow arrangement, inlet system, level detection and controls can all be relevant to diagnosis.

Error Code = Diagnostic Clue.

Error Code ≠ Automatic Parts Order.

Commercial Glasswasher Filling Error Codes

Filling faults generally mean the machine hasn't achieved an expected water condition.

Possible areas for investigation can include:

  • Incoming water supply

  • Isolation valve

  • Water pressure or flow

  • Inlet filter

  • Solenoid/inlet valve

  • Overflow arrangement

  • Water-level sensing

  • Pressure system

  • Wiring

  • Control system

The machine may know:

"The expected level hasn't been reached."

It may not know:

why.

Glasswasher not filling?

Commercial Glasswasher Drain Error Codes

A drainage fault can occur when water isn't removed in the expected way.

Possible areas can include:

  • Filters

  • Drain hose

  • Drain restriction

  • Site waste

  • Overflow arrangement

  • Drain pump where fitted

  • Water-level system

  • Wiring

  • Controls

Before replacing a pump:

Diagnose the Drainage System.

Commercial Glasswasher Heating & Temperature Error Codes

Heating faults require an important distinction.

Is the machine:

Not producing enough heat?

Or:

Not measuring the temperature correctly?

These aren't necessarily the same fault.

Depending on the machine, relevant components may include:

  • Heating element

  • Boiler

  • Tank heater

  • Temperature probe

  • Thermostat

  • Safety thermostat

  • Relay

  • Contactor

  • Wiring

  • Water level

  • Scale

  • Electronic controls

The Eswood Smartwash codes demonstrate this clearly: its diagnostic system distinguishes between several specific temperature-probe conditions rather than treating every temperature problem as a failed heater.

Commercial Glasswasher Door Errors

If a machine doesn't recognise that the door is correctly closed, it may prevent operation.

Possible causes can include:

  • Door not fully closed

  • Obstruction

  • Door alignment

  • Door switch

  • Switch actuator

  • Hinges

  • Wiring

  • Control input

Again:

The operator may see:

Door closed.

The controller may receive:

Door open.

Machine won't recognise the closed door?

Commercial Glasswasher Control Panel Errors

The control panel is often where the error appears.

That doesn't mean the control panel caused it.

Think of the display as the machine's messenger.

It may be telling you about a problem involving:

  • Water

  • Heating

  • Temperature

  • Drainage

  • Door

  • Pump

  • Sensor

  • Safety system

The Control Panel Shows the Symptom. It Doesn't Always Cause It.

Buttons, display or controls also behaving strangely?

Troubleshoot Commercial Glasswasher Control Panel Problems →

Why Did the Error Disappear When We Reset the Glasswasher?

This is common.

The error appears.

Someone switches the machine off.

They switch it back on.

The code disappears.

Problem fixed?

Maybe not.

The Eswood Smartwash operating information itself notes that turning the machine off and back on resets its fault notification, but if the problem reoccurs after following the specified instructions, authorised service should be contacted.

That's an important distinction.

Resetting the notification isn't necessarily repairing the fault.

If the same error keeps returning, investigate why.

Why Does the Error Only Appear During Busy Service?

Tell us this.

It's useful information.

Does the code appear:

  • Immediately after startup?

  • During filling?

  • During washing?

  • During rinsing?

  • During draining?

  • Once the machine gets hot?

  • After multiple consecutive cycles?

  • Only during peak service?

  • Intermittently?

A machine that operates normally for its first few cycles and then faults may present a different diagnostic picture from one that faults immediately after startup.

When It Happens Is Part of the Diagnosis.

Why Is My Glasswasher Showing More Than One Error?

Several codes don't necessarily mean several parts have failed.

Glasswasher systems interact.

For example:

Filling problem

can create:

incorrect water level

which can prevent:

correct heating

which can interrupt:

cycle progression.

One underlying fault can therefore produce several symptoms.

Look for the Root Cause — Not Just the Last Code Displayed.

Can Scale Cause a Glasswasher Error?

Potentially, indirectly.

Scale can affect systems including:

  • Heating

  • Water flow

  • Boilers

  • Heating elements

  • Valves

  • Other water-contact components

The Eswood Smartwash documentation specifically warns that feed-water quality should not create excessive calcium and dissolved-mineral buildup on heating elements.

But visible scale still doesn't prove it caused the particular error.

Scale becoming a recurring issue?

Troubleshoot Commercial Glasswasher Scale Build-Up →

Can Water Softener Problems Lead to Glasswasher Faults?

Potentially.

If water treatment isn't performing correctly, hardness-related scale can progressively affect components within the machine.

But the glasswasher may report the resulting condition — such as poor heating — rather than specifically displaying:

"Water softener fault."

Concerned about hard water?

Should I Keep Using a Glasswasher With an Error Code?

It depends on the error and symptoms.

Stop using the machine and arrange appropriate assessment if you notice:

  • Burning smell

  • Smoke

  • Repeated electrical tripping

  • Water reaching electrical components

  • Significant leaking

  • Overflowing

  • Severe grinding

  • Abnormal overheating

  • Unsafe door operation

  • Other obvious safety concerns

Safety-related faults shouldn't be repeatedly reset simply to get through service.

What Staff Can Check Before Calling Worldwide CDM

Take a Photo of the Error

Do this before resetting anything.

Record the Brand

For example:

Eswood

Record the Exact Model

For example:

Smartwash 400

Record the Complete Code

For example:

Er02

rather than:

"It had some drain error."

Note When It Happened

Was the machine:

  • Filling?

  • Heating?

  • Washing?

  • Rinsing?

  • Draining?

Record Other Symptoms

Tell us about:

  • Leaking

  • Slow heating

  • Unusual noises

  • Water remaining inside

  • Poor cleaning

  • Door problems

  • Intermittent operation

Check Normal Operator-Maintenance Items

Follow the manufacturer's normal operating and cleaning instructions for things such as accessible filters, wash/rinse arms and obvious external obstructions.

Don't dismantle electrical or internal systems.

What Not to Do

Don't:

  • Use an error-code list from another manufacturer

  • Assume every code means a failed component

  • Order expensive parts solely from the error number

  • Repeatedly reset serious faults

  • Bypass safety switches

  • Bridge interlocks

  • Modify wiring

  • Open electrical systems without appropriate qualifications

  • Continue operating equipment where water is reaching electrical components

  • Ignore burning smells, smoke or repeated tripping

Commercial glasswashers combine:

Water + Heat + Electricity

Internal electrical fault diagnosis should be carried out by appropriately qualified personnel.

How Worldwide CDM Diagnoses Commercial Glasswasher Error Codes

Step 1 — Identify the Machine

We start with:

Manufacturer + Model + Complete Error Code

A photo is ideal.

Step 2 — Verify What the Code Means

We determine what that error relates to for the relevant equipment.

Not another manufacturer's machine.

Not a random internet list.

Your machine.

Step 3 — Understand When It Happens

The point in the cycle can provide important clues.

Step 4 — Investigate the Relevant System

Depending on the fault, this can include:

  • Filling

  • Water level

  • Heating

  • Temperature sensing

  • Rinsing

  • Pumps

  • Drainage

  • Door system

  • Wiring

  • Electrical controls

  • Safety systems

Step 5 — Identify the Root Cause

This is the important part.

Not:

"What part is associated with this code?"

But:

"Why did the machine generate this code?"

Step 6 — Explain the Repair

You'll know what we've found and what work is required.

Step 7 — Fix What Matters

We repair the actual fault rather than replacing components based on assumptions.

Find the Cause. Fix What Matters.

Why Correct Error-Code Diagnosis Can Save Money

Imagine an Eswood Smartwash shows Er02.

The documented fault is no drainage.

Someone assumes:

Drain pump.

A new pump is ordered.

But the underlying problem was a drainage restriction.

Or the machine displays a temperature-related code.

Someone assumes:

Heating element.

But the diagnostic system is actually reporting a temperature-probe condition.

Or a machine won't start and shows a door message.

Someone assumes:

Control board.

But the door isn't being detected correctly.

This is why Worldwide CDM doesn't treat error codes as shopping lists for spare parts.

Code → System → Diagnosis → Cause → Repair

Not:

Code → Guess → Replace.

Frequently Asked Questions

What does my commercial glasswasher error code mean?

It depends on the manufacturer and exact model. Error codes can relate to filling, drainage, heating, temperature sensing, rinsing, doors, controls and other systems.

Are commercial glasswasher error codes universal?

No. Never assume a code from one manufacturer has the same meaning on another machine.

What does Er01 mean on an Eswood Smartwash 400?

For the Smartwash 400/500 documentation referenced here, Er01 indicates that the rinsing cycle wasn't completed correctly.

What does Er02 mean on an Eswood Smartwash?

Er02 is a no-drainage fault on the Smartwash 400/500. The manufacturer information directs attention to the drainage arrangement, including the drain pipe, siphon, filters and overflow procedure.

What does Er03 mean on an Eswood Smartwash?

Er03 is identified as a rinse-temperature reset error involving boiler temperature not resetting within the set time during the wash cycle.

What does Er04 mean on an Eswood Smartwash?

Er04 indicates the wash tank hasn't filled to level. Manufacturer checks include the water connection, water tap and overflow position.

What does Er05 mean on an Eswood Smartwash?

Er05 is a wash-tank temperature-probe open condition, where the machine isn't reading the tank-temperature value.

What does Er06 mean on an Eswood Smartwash?

Er06 is the corresponding shorted wash-tank temperature-probe condition.

What does Er07 mean on an Eswood Smartwash?

Er07 indicates a boiler-temperature probe open condition, meaning the machine isn't measuring boiler temperature as expected.

What does Er08 mean on an Eswood Smartwash?

Er08 identifies a shorted boiler-temperature probe condition.

What does ErSF mean on an Eswood Smartwash?

ErSF is an electromechanical safety fault associated with temperature or wash-tank level being outside safe values. The manufacturer directs the user to authorised service.

What does "door" mean on an Eswood Smartwash display?

For the Smartwash 400/500, door is a display message indicating the door is open. It is not listed as one of the Er01–Er08 error codes.

Does an error code tell me which part needs replacing?

Not necessarily. It may identify the system or abnormal condition rather than the exact failed component.

Why does the error disappear when I restart the glasswasher?

Restarting can reset a fault notification. If the underlying condition remains, the code can return.

Does a drain error mean I need a new drain pump?

No. Drainage problems can also involve filters, restrictions, hoses, waste systems, water-level detection and other components.

Does a heating error mean the heating element has failed?

Not necessarily. Heating and temperature faults can involve the heater, temperature sensing, electrical controls, water level or other components.

Should I photograph the error code?

Yes. Photograph the code before resetting the machine and record the manufacturer and exact model.

Can Worldwide CDM diagnose my glasswasher error code?

Yes. Provide the brand, model, exact code and preferably a photograph of the display when booking.

Commercial Glasswasher Showing an Error Code?

Don't Just Clear It. Understand Why It Appeared.

The error code gives us a clue.

The machine gives us symptoms.

The operating sequence gives us context.

Diagnosis brings those pieces together.
