Fridge not cooling

Failed evaporator fan or condenser fan motor stops airflow — fridge warms while freezer maintains temperature.

NoFrost system failure — frost build-up

Defrost heater or thermostat failure causes ice to accumulate on the evaporator coils, blocking airflow across both compartments.

Ice maker not producing ice

Clogged water inlet valve or failed ice maker module — common on B36 and B21 counter-depth models with built-in ice systems.

Water pooling in crisper drawer

Blocked defrost drain or cracked drain pan causes meltwater to collect and refreeze at the bottom of the fridge section.

Control board error codes

Display faults or sensor errors lock the appliance into a protection cycle — board diagnosis and replacement if needed.

Compressor not starting

Failed start relay or inverter board on linear compressor models prevents the unit from reaching set temperature.

E18 drain error

Blocked drain pump filter or kinked drain hose prevents water from evacuating — machine halts mid-cycle.

E17 / E23 water fill error

Faulty water inlet valve or pressure sensor fault prevents the drum from filling to the correct level.

Door gasket leaking or mouldy

Torn bellows seal allows water to escape onto the floor and causes persistent drum odour on 800 series models.

Drum bearing noise

Worn rear drum bearing produces a loud grinding or rumbling noise during spin — worsens progressively if left unrepaired.

Door latch not locking

Failed door interlock prevents the cycle from starting — washer powers on but won't respond to cycle selection.

Excessive vibration during spin

Worn shock absorbers or failed suspension springs cause violent movement during high-speed spin cycles.

Heat pump not drying — clothes still damp

Failed heat pump evaporator or condenser blockage reduces drying efficiency — cycles complete but clothes remain wet.

Drum not turning

Worn or snapped drive belt or failed idler pulley — motor runs but drum stays stationary.

E5 / E11 condenser error

Blocked or failed condenser on heat pump models triggers a fault code and stops the drying cycle from completing.

Moisture sensor not ending cycle

Coated or corroded sensor bars misread dryness — dryer runs too long or cuts off before clothes are fully dry.

Squealing or grinding drum noise

Worn drum glides or rear bearing allows metal-on-metal contact — progressively worsens and can seize the drum.

Door switch failure — won't start

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

E15 AquaStop flood error

Water leak in the base triggers the AquaStop flood sensor — unit shuts down completely to prevent floor damage.

E24 / E25 drain error

Blocked sump filter or failed drain pump motor leaves standing water in the tub after the cycle ends.

Dishes not cleaning properly

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

PureDry not drying dishes

Failed zeolite drying system or vent fan issue on 800 series leaves dishes wet at the end of the cycle.

Control panel unresponsive

Main PCB or touchpad failure — buttons register nothing or the unit starts and stops unexpectedly.

Door latch not securing

Worn door latch or failed latch switch prevents the cycle from starting — dishwasher powers on but won't run.

Induction zone not detecting cookware

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

Gas burner won't ignite

Cracked or fouled igniter tip prevents spark — burner clicks continuously without lighting on HGI gas models.

FlexInduction zone not bridging

Relay fault prevents the large FlexInduction zone from combining into a single expanded cooking area.

Touch control panel error

Control board communication fault causes display errors, zone lockouts or all burners becoming unresponsive simultaneously.

Cracked glass cooktop

Thermal shock or impact fractures the ceramic-glass surface — continued use risks electrical exposure and requires full replacement.

Gas valve not opening

Faulty gas valve solenoid coil prevents gas flow to the burner even when the igniter is sparking normally.

Oven not reaching temperature

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

European Convection fan not running

Worn convection fan motor or broken blade causes hot spots and uneven baking — a common issue on HBL 8000 series.

Door locked after self-clean

Door latch motor or lock switch fault leaves the oven door locked after the self-clean cycle completes.

Temperature sensor fault (E1 / E2)

Open or shorted oven temperature sensor sends incorrect readings to the control board — oven overheats or underheats.

SteamAssist not working

Blocked steam nozzle or failed steam generator prevents moisture injection — steam cook programs produce no benefit.

Interior light not working

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