Commercial Dishwasher Repair in Perth

PEMS diagnoses and repairs commercial dishwashers for restaurants, hotels, aged care facilities, and contract caterers across the Perth metro area.

Commercial dishwashers run hard service and fail at the worst possible times -- mid-service, before a function, or during a health inspection. Underbench, hood-type, and conveyor machines each have distinct failure modes that general electricians and appliance repairers are rarely equipped to handle. PEMS works exclusively on commercial food equipment, so a technician who knows the machine arrives -- not someone learning it on your time.

Common Commercial Dishwasher Faults We Fix

Not Reaching Sanitising Temperature

Low final rinse temperature is the most common reason a dishwasher fails a health audit -- the cause is typically a failed heating element, faulty thermostat, or scale-blocked booster heater. PEMS tests wash and rinse cycle temperatures against manufacturer specifications, replaces defective heating components, and descales the booster where required.

Poor Wash Results and Residue on Crockery

Dirty or filmy crockery after a cycle usually points to blocked spray arms, a worn wash pump impeller, or incorrect water pressure at the inlet. PEMS clears blocked jets, inspects pump performance under load, and checks inlet pressure and dosing pump calibration to restore effective wash action.

Machine Not Draining or Flooding

Drain failures are caused by a seized or failed drain pump, a blocked sump filter left unserviced, or a faulty drain solenoid valve failing to open on cycle completion. PEMS clears blockages, tests solenoid valve operation, and replaces drain pump assemblies to stop flooding and standing water that holds bacteria.

Control Faults and Error Codes

Modern commercial dishwashers from Winterhalter, Hobart, Comenda, and similar brands display fault codes that require brand-specific diagnostic knowledge to interpret correctly. PEMS reads and clears control board errors, replaces failed sensors and PCBs, and verifies full cycle operation before leaving the site.
