Frequently Asked Questions

Why is my Washtech dishwasher not cleaning dishes properly?

Poor cleaning performance is one of the most common issues with commercial dishwashers. It may be caused by blocked wash arms, clogged filters, incorrect detergent dosing, low wash temperatures, insufficient water pressure or worn wash pump components. Our technicians can diagnose the cause and restore your Washtech dishwasher to optimal performance.

Why won't my Washtech dishwasher drain?

A Washtech dishwasher may fail to drain due to blocked filters, food debris, a damaged drain pump, blocked drain hoses or electrical faults. Continuing to use the machine without proper drainage can lead to further damage, so it's best to arrange a professional inspection as soon as possible.

My Washtech dishwasher isn't heating. What could be causing it?

If your Washtech dishwasher isn't reaching the correct wash or rinse temperature, the problem may involve the heating element, thermostat, temperature sensor, electrical components or control system. Commercial dishwashers rely on correct water temperatures to achieve proper cleaning and sanitation, so heating faults should be repaired promptly.

My Washtech dishwasher is displaying a fault code. Can you help?

Yes. Modern Washtech commercial dishwashers feature built-in fault diagnosis that displays error codes when a problem is detected. Our technicians can diagnose these faults, identify the underlying issue and carry out the required repairs to get your machine back into service.

How often should a Washtech commercial dishwasher be serviced?

For busy commercial kitchens, preventative servicing is generally recommended every 6 to 12 months, depending on usage. Regular servicing helps identify worn components early, improves wash performance and reduces the risk of unexpected breakdowns during busy trading periods.

Yes. Worldwide CDM repairs and services a wide range of Washtech commercial dishwashers, glasswashers and passthrough dishwashers used throughout Sydney's hospitality industry. If you're unsure of your model, simply contact us with the model and serial number.

Why is my Washtech dishwasher leaving white marks or cloudy glasses?

Cloudy glasses or white residue can be caused by hard water, incorrect detergent or rinse aid dosing, mineral scale build-up or blocked rinse jets. Regular servicing and correct chemical settings help maintain sparkling wash results.

Why does my Washtech dishwasher smell?

Unpleasant odours are usually caused by food debris, grease build-up, dirty filters or blocked wash components. Cleaning the machine regularly and scheduling preventative maintenance helps keep your dishwasher hygienic and operating efficiently.

Can preventative maintenance reduce repair costs?

Yes. Routine servicing allows worn parts to be replaced before they fail, helping to reduce costly emergency repairs, minimise downtime and extend the lifespan of your commercial dishwasher.
