WashTech Commercial Dishwasher Not Heating Water – Paradise Point

WashTech Commercial Dishwasher Not Heating Water – Paradise Point

A customer in Paradise Point contacted ISB Electrical because their WashTech commercial dishwasher was not heating water. The machine was operating, but the wash and rinse water temperature was not reaching the correct level for commercial dishwashing.

Commercial dishwashers rely on correct water temperature for proper washing, sanitising and drying results. When a WashTech dishwasher does not heat water, the fault can be caused by a faulty boiler tank heating element, wash tank element, thermostat, pressure switch, contactor, wiring fault or control board issue. In this case, the boiler tank heating element was tested and found faulty.

Inspection and Diagnosis

• Checked the commercial dishwasher power supply and safety condition
• Confirmed the WashTech dishwasher was not heating water correctly
• Checked water temperature during operation
• Inspected the boiler tank heating circuit
• Tested the boiler tank heating element
• Checked visible wiring, terminals and connections
• Confirmed the heating element had open circuit windings
• Confirmed the boiler tank heating element was faulty

Fault Found

The fault was caused by a faulty boiler tank heating element. The element had open circuit windings, meaning it could not produce heat and the dishwasher could not heat the water properly.

A failed boiler tank element can prevent the rinse water from reaching the required temperature. This can affect wash performance, drying results and commercial hygiene standards.

Repair Required

The faulty boiler tank heating element needs to be replaced. After replacement, the WashTech commercial dishwasher should be tested to confirm the boiler heats correctly, water temperature rises normally and the machine completes the cycle properly.

The customer was advised that the dishwasher should not be relied on for normal commercial operation until the heating fault is repaired and the water temperature has been tested.

Common Causes of Commercial Dishwasher Not Heating Water

• Faulty boiler tank heating element
• Open circuit heating element windings
• Faulty wash tank heating element
• Faulty thermostat or temperature sensor
• Damaged contactor or relay
• Loose or burnt wiring connection
• Pressure switch or water level issue
• Main control board fault
