Norris Commercial Dishwasher Not Working – Southport

Norris Commercial Dishwasher Not Working – Southport

A customer in Southport contacted ISB Electrical because their Norris commercial dishwasher was not working correctly. The machine was unable to operate normally and required urgent inspection because it was used in a commercial environment.

Commercial dishwashers rely on strong wash pump operation to circulate water through the spray arms. If the wash motor fails, the dishwasher may stop washing, trip power, make a humming noise, overheat or stop working completely.

Inspection and Diagnosis

• Checked the commercial dishwasher power supply and safety condition
• Confirmed the Norris dishwasher was not operating correctly
• Checked wash cycle operation
• Inspected the wash pump and motor area
• Checked motor wiring and terminal connections
• Tested the wash motor windings
• Checked for burning smell, overheating and winding damage
• Confirmed the wash motor windings were burning and the motor was faulty

Fault Found

The fault was caused by damaged wash motor windings. The motor windings were burning, which means the wash motor was no longer safe or reliable to continue operating.

When wash motor windings start burning, the motor can lose power, overheat, trip protection devices or fail completely. Continued use can also damage wiring, terminals and surrounding components.

Repair Required

The faulty wash motor requires replacement. After replacing the wash motor, the dishwasher should be tested through a full wash cycle to confirm correct water circulation, spray pressure and safe motor operation.

The customer was advised not to continue using the commercial dishwasher while the wash motor windings are burning, as this can create further electrical damage and safety risk.

Common Causes of Commercial Dishwasher Not Working

• Burnt or damaged wash motor windings
• Faulty wash pump motor
• Motor overheating during operation
• Blocked wash pump causing motor overload
• Damaged wiring or motor terminals
• Faulty capacitor or motor start circuit
• Control board not supplying motor correctly
• Water leak or moisture affecting electrical components
