Door sensor circuit fault

Fault in the door sensing circuit.

Drying fan fault

The drying fan motor (zeolite fan on CrystalDry models) is defective.

Heater fault

The heater inside the heat pump (circulation pump with built-in heater) has a fault, so water is not heated.

Zeolite chamber heater fault

The heater in the zeolite drying chamber has a fault.

Limescale on heater

Scale buildup in the heat pump is slowing heating.

Flow meter / fill flow fault

The flow meter does not register water coming in as expected.

Water in base - leak protection active

Water has collected in the base pan and lifted the float switch; the leak protection shuts off fill and drains.

Water not entering

The dishwasher is not filling.

Water level too low

Not enough water reached the tub during fill.

Detergent dispenser solenoid circuit

Fault in the detergent dispenser solenoid circuit.

Heat pump blocked

The heat pump (circulation pump) is blocked.

Lower spray arm reference not found

The PowerControl lower spray arm could not find its reference position.

Delay start set (not a fault)

Shows the hours remaining on delay start.

Water in base / flood

The flood sensor has found water in the base. Often caused by too much foam rather than a real leak.

Wash motor fault

The wash motor cannot run properly. Debris or glass in the rotor is the first thing to check.

Water temperature fault

Water temperature is out of range, often because incoming water is too hot.

Heating fault

Heating element or temperature sensor problem.

Fault in the electronic control system.

Turbidity sensor failure

The water-clarity sensor reading is invalid.

Vent fan speed wrong

The drying vent fan is not running at the expected speed.

Water level / pressure sensor signal

The control is not getting a valid water-level reading from the pressure sensor.

Leak alert or control reset needed

On models with Floor Protect alert it means a possible leak and the unit will not start; on other listed models the control needs a reset.

Slow drain (pump-out too long)

Pump-out took longer than the control allows, usually from a partial drain restriction. GE lists about 2 minutes; a service-code list uses about 95 seconds, so the limit varies by model.

Drain time far exceeded

Listed as pump-out exceeding a long limit; meaning varies by model.

Will not drain

GE lists C3 as the dishwasher failing to drain. A service-code list adds that the control got no signal back from the pump circuit when it called for pump-out.

Refilled twice / float problem

The unit took on water twice after a power interruption, which usually means the float is stuck or failed, or the drain/sump is clogged.

Pump-out time too short

The control saw the drain stage end sooner than expected, often because too little water was in the tub.

Incoming water too cool

GE lists C6 as incoming water below the expected temperature (GE cites about 120 °F at the dishwasher).

Water temperature sensor circuit

GE lists C7 as a failure in the water temperature sensor (thermistor) circuit.

Detergent cup blocked

The detergent cup could not open fully, so detergent was released late or not at all. The wash still ran.

Detergent cup not closed

The control sees the detergent cup open, so it will not start the cycle.

Failure to drain

Water was not removed from the tub within the expected time.

No water detected

The water level did not rise during fill and the cycle stops.

Leak detected in base

The leak sensor found water; the cycle is cancelled.

Power failure

Power was interrupted during or before the cycle. Not a fault by itself.

Pressure sensor signal invalid

The control gets an invalid signal from the pressure (water level) sensor; the cycle won't start or cancels.

Leak detected

Water in the base has activated the leak float.

Oversudsing (bubble) error

Excess suds detected.

Wash motor error

The wash motor or the wiring between motor and control is faulty.

Control lock on (not a fault)

Heat Dry temperature

Temperature problem in the heat-dry system.

Auto-open door error

The automatic door opener could not open the door.

Excess water / overfill

Water in base pan (float switch)

The base-pan float switch tripped because water reached the pan.

Circulation pump fault

The circulation pump or its drive reports a fault.

Low water level / clogged filter (model-dependent)

On many models it points to low water level, often from a clogged filter; Samsung's US page ties 1E on some rotary models to a high-temperature heater fault. Check the model first.

Wash pump fault

Problem with the circulation (wash) pump operation.

Water supply problem

Not enough water is coming in, or supply pressure/temperature is outside spec.

UI to main control communication

The user interface lost communication with the main control.

Thermistor / OWI sensor

Whirlpool points to the thermistor or the optical water indicator (turbidity) sensor.

Heating system error

Heater circuit problem (element or relay open).

Heating error (per Whirlpool)

Whirlpool's page lists a heating error; a service-code list ties F4E3 to the wash motor circuit on another platform.

User interface / main control communication error

Whirlpool lists F6E1 as a user interface or main control error, and a service-code list describes the UI getting no communication from the main control. Some older third-party lists tie the code to no water fill instead; trust the tech sheet for the exact platform.

Excessive suds

Sensors found foam in the bottom of the tub.

Float switch fault

The float (overfill) switch reads abnormally.

Wash motor error

Whirlpool lists a wash motor error.
