Fridge not cooling properly

Failed evaporator fan or blocked condenser coils prevent adequate airflow — fridge warms while freezer compartment holds temperature.

NoFrost system not defrosting

Failed defrost heater or defrost thermostat causes ice to build up on the evaporator coils, blocking airflow and reducing cooling.

Water pooling under the crisper drawer

Blocked defrost drain or cracked drain pan allows meltwater to collect and refreeze beneath the vegetable bins.

Error codes E1, E3, E4

Temperature sensor, evaporator fan, or defrost circuit faults that trigger the display and lock the appliance into a protection mode.

Door seal not sealing properly

Warped or torn door gasket allows warm air ingress — compressor runs continuously, energy use spikes, and condensation forms inside.

Compressor clicking and cycling

Start relay failure or worn compressor causes rapid on/off cycling without pulling the cabinet down to set temperature.

F01 / F02 water inlet error

Kinked inlet hose, blocked mesh filter, or failed water valve prevents the drum from filling and locks the cycle.

F18 drain error

Blocked debris filter or failed drain pump motor stops water from evacuating — washer halts mid-cycle with a full drum.

Door gasket leaking or mouldy

Torn or collapsed bellows seal allows water to escape onto the floor during spin. Also a common source of persistent drum odour.

Excessive vibration and banging

Worn shock absorbers or loose counterweight bolts cause the drum to move violently during high-speed spin cycles.

F21 motor / drum not spinning

EcoSilence Drive motor fault or Hall sensor failure stops the drum before spin starts — often misread as a load balance error.

AquaStop triggered — won't start

AquaStop flood protection activates after a small leak at the base — unit locks out until the tray is cleared and the sensor resets.

No heat — clothes still damp

Failed heating element or heat pump compressor fault. On condenser models, a blocked lint filter is the most common cause of heat loss.

Drum not turning

Worn or snapped drive belt, or failed idler pulley — motor runs but drum stays stationary and clothes sit in a hot, static drum.

Condenser water tank not draining

Full or blocked condensate tank prevents the dryer from completing cycles — unit pauses and displays a tank-full warning.

Squealing or grinding drum noise

Worn drum glides or rear bearing allows metal-on-metal contact. Progressively worsens and can seize the drum if left unrepaired.

AutoDry sensor not ending cycle

Coated or corroded moisture sensor bars stop detecting dryness — dryer runs indefinitely or shuts off too early leaving clothes damp.

Door switch failure — won't start

Broken door latch microswitch prevents the control board from receiving the door-closed signal, blocking all cycle starts.

E24 / E25 drain error

Blocked sump filter or failed drain pump prevents water from clearing after the wash cycle — standing water remains in the tub.

Dishes not cleaning properly

Clogged spray arm holes or failed circulation pump reduces water pressure — upper rack items come out with residue.

E15 AquaStop water leak error

Water detected in the base tray triggers AquaStop flood protection — unit shuts down and drains until the tray sensor is cleared.

PerfectDry not drying dishes

Failed zeolith mineral cartridge or vent flap fault leaves dishes wet — Serie 8 models are especially sensitive to zeolith degradation.

Control panel unresponsive

Main PCB or touchpad membrane failure — buttons register nothing or random cycles start without input.

Loud grinding or humming noise

Debris lodged in the wash pump impeller or worn motor bearings produce mechanical noise that escalates with every cycle.

Gas burner won't ignite

Cracked or carbon-fouled igniter tip prevents spark generation — burner clicks continuously without lighting.

Induction burner not detecting cookware

Induction coil or power inverter board fault stops the zone from energizing — no heat even with compatible magnetic cookware.

Surface element stays on max heat

Failed infinite switch locks the element at full power regardless of the dial position — a burn and fire hazard requiring immediate repair.

E0 / E2 control board error

Touch control PCB communication fault — display glitches, burners become unresponsive, or all zones lock out simultaneously.

Cracked glass cooktop

Thermal shock or impact cracks the ceramic-glass surface. Continued use risks electrical exposure — requires full surface replacement.

FlameSelect not adjusting flame level

Gas valve solenoid or control board fault prevents the 9-step FlameSelect system from modulating flame intensity accurately.

Oven not reaching set temperature

Failed bake or broil element reduces heat output — oven takes far longer to preheat or never reaches the target temperature.

4D HotAir fan not running

Worn convection fan motor or broken blade causes uneven cooking — hot spots develop and baked goods brown inconsistently.

Door lock error after self-clean

Door latch motor or lock switch fault leaves the oven locked after pyrolytic self-clean or triggers a false lock during normal use.

Temperature sensor fault (E1 error)

Open or shorted NTC temperature sensor sends false readings to the control board — oven overheats, under-heats, or shuts down mid-cycle.

Interior light not working

Burned-out halogen or LED bulb, or failed light socket board — makes monitoring food during baking impossible.

Steam function not working

Blocked steam nozzle or failed steam generator on CombiSteam models prevents moisture injection — steam programs produce no benefit.
