Door will not lock or machine thinks the door is open.
Fault with the door lock mechanism, wiring to the lock, or the main control board.
Check that the door is closed properly. Inspect the door lock for damage. Test wiring between the lock and the PCB. Replace door interlock if faulty.
Dishwasher fails to fill with water within the expected time.
Water supply issue, kinked inlet hose, or faulty water inlet valve/solenoid.
Check water supply is on. Straighten the inlet hose. Clean the filter in the hose connection. Test and replace the inlet valve if it has failed.
Machine is not filling with water or filling very slowly.
Water supply is turned off, inlet hose is kinked or blocked, inlet valve filter is blocked, or the water inlet valve has failed.
Ensure water tap is fully open. Check the inlet hose for kinks. Clean the filter inside the water inlet valve. Test and replace the valve if necessary.
Dishwasher is not draining the water.
Clogged filters, blocked drain hose, or a faulty drain pump.
Clean the main filter and microfilter inside the dishwasher. Check the drain hose for kinks and blockages. Inspect the drain pump for debris or failure.
Machine fails to drain the water.
Drain filter is clogged, drain pump is blocked or faulty, or the drain hose is kinked or blocked.
Clean the drain pump filter. Check the pump impeller for obstructions. Ensure the drain hose is not kinked. If the pump is humming but not turning, it may need replacement.
Water is not heating up, resulting in poor wash performance.
Faulty heating element, wiring issue, or a fault on the main control board.
Test the heating element for continuity. Check the wiring to the heater. If both are okay, the fault may be with the control board's relay.
Machine has overfilled with water or leak detected in base.
Pressure switch fault, water inlet valve stuck open, or an internal leak has activated the anti-flood switch in the base.
Check pressure switch and its tubing for blockages. Test water inlet valve to ensure it closes correctly. If water is in the base, find and repair the leak.
Dishwasher has stopped mid-cycle and may show signs of leaking.
The machine has overfilled, or the anti-flood switch in the base has been activated by a leak.
Tilt the machine forward to drain water from the base and reset the switch. Find and fix the source of the leak (e.g., hose, seal, or pump).
Water is not heating up or cycle gets stuck.
The NTC temperature sensor is faulty (open or short circuit).
Test the resistance of the NTC sensor (should be around 20k ohms at room temperature). Check wiring to the sensor. Replace the NTC sensor if faulty.
Motor not turning or spinning erratically.
Fault with the motor tacho (speed sensor), motor brushes are worn, or there is a motor wiring issue.
Inspect and replace worn motor carbon brushes. Check the motor tacho coil for continuity. Inspect motor wiring and connections.
Motor is not running at all or runs at full speed uncontrollably.
A short circuit in the motor's power triac on the main control board (PCB).
This error almost always requires the main control board to be professionally repaired or replaced.
Machine trips the circuit breaker, or water does not heat.
The heating element has failed or has a short circuit to earth.
Test the heating element for continuity and for an earth leakage. Replace the heating element if it is faulty.
Oven not heating correctly, displays error.
Oven temperature sensor (NTC/thermistor) has failed or its connection is loose (open circuit).
Check the wiring connection to the temperature sensor. Test the sensor's resistance; if it's out of range or shows an open circuit, replace it.
Oven overheating or not heating correctly.
The oven temperature sensor (NTC/thermistor) has a short circuit.
Test the resistance of the temperature sensor. If it reads very low or zero ohms, it has shorted and must be replaced.
Oven has shut down and displays an error.
Overheating detected by the safety thermostat or the main control board.
Check for obstructions to the cooling fan. Test the cooling fan for operation. Test the safety thermostat to see if it has tripped or failed.
Oven overheats, electronics may shut down after use.
The cooling fan that cools the electronic components is not working.
Check for obstructions in the fan blades. Test the fan motor for continuity and voltage. Replace the cooling fan if it is faulty.
Oven door will not lock or unlock, especially for pyrolysis (self-cleaning) modes.
The door locking mechanism is jammed or has failed electronically.
Disconnect power to reset. If the lock remains stuck, it may need to be manually released. Test the motor and microswitches in the lock assembly and replace if needed.
The word 'STOP' is flashing on the oven display and it will not operate.
This can indicate a major electronic fault, a problem with the door lock, or that the oven is in 'demo' or 'showroom' mode.
First, try to disable demo mode by pressing and holding a combination of buttons (consult manual). If not in demo mode, it indicates a hardware failure requiring service, often with the main board or door lock.
