Dishwashers

Dishwashers error codes

Dishwasher error codes cluster around water flow. Not draining is by far the most common, and it's usually a clogged filter or drain hose rather than a failed part. The rest split between not filling, leaks that trip a base float switch, and heating or temperature-sensor faults.

A surprising number clear with nothing more than a filter clean and a power reset. Choose your brand below — every code lists its meaning, likeliest cause, and a verified step-by-step fix, with a clear note when a repair really does need a technician.

iC0Electronic control system fault i10Low water fill detected i20Dishwasher did not drain i30Leak or overflow in the base pan i40Clogged filter or sump restriction i50Wash or drain motor fault i60Water heating system fault iF0Water flow / filter restriction UODrying vent assembly fault

GE dishwashers show C-codes and status indicators (C1/C2 drain, H2O fill, LEAK). 9 below.

H2ONot enough water reaching the dishwasher C1Drain took longer than two minutes C2Total pump-out time exceeded seven minutes C4Overfill or float error after power loss C5Pump-out time too short C7Water temperature sensor circuit fault C8Detergent cup blocked from opening PFPower failure during a cycle LEAKLeak detected, cycle cancelled

LG dishwashers show OE (drain), IE (fill), LE (motor) and AE (leak) among others. 8 below.

OEDrain error — water not draining out IEWater inlet error — tub not filling enough FEFill/overfill error — too much water LEMotor error — wash motor cannot operate tEThermal error — water temperature/thermistor fault AELeak detected — water in the base nEVario (spray-diverter) motor error HEHeater error — water not heating or overheating

Samsung

Samsung dishwashers use digit-letter codes (4C water, 5C drain, LC leak) with older 4E/5E/LE equivalents. 8 below.

4CWater supply fault; not filling correctly 5CDrain fault; unable to pump water out LCLeak detected in the base pan OCOverfill; too much water in the tub 9EInsufficient / low water level in tub tCTemperature sensor (thermistor) fault 3CWash (circulation) pump / motor fault bEStuck or shorted control-panel button

Bosch

Bosch dishwashers use E## codes; E15 (AquaStop leak), E24 (drain) and E22 (filter) dominate. 7 below.

E15Anti-flood float detected water in base tray E24Dishwasher not draining, drain path blocked E22Filter blocked, water cannot drain E25Drain pump blocked or pump cover loose E09Heating element / flow heater defective E01Heat-pump / control board circuit fault E02Temperature sensor / control relay fault

Whirlpool

Whirlpool dishwashers use the F#E# system (F9E1 drain, F8E1 fill, F6E4 flow meter). 7 below.

F9E1Long drain — dishwasher is not draining properly F8E1Water fill fault — abnormal or low water level during fill F6E4Flow meter fault — fill turbine misreading water volume F2E2User interface fault — stuck button or panel comms loss F3E1Water temperature sensor (thermistor/OWI) fault F8E4Overflow/leak — water in the base tray float switch F7E1Heating fault — water not heating / open element
