Dishwasher error codes

LC (LE on some models) means the leak sensor found water in the base. The dishwasher may keep draining until it dries. The usual causes are a leaking pump seal or internal hose, a worn door gasket, or heavy suds from regular dish soap.

OC (0C or oE on some models) means the water level in the tub is too high, usually because water isn't draining away properly. The usual causes are a clogged filter or sump, a kinked drain hose or blocked garbage disposal inlet, or a water inlet valve that doesn't shut off fully.

5C (5E on some models) means the water didn't drain. The usual causes are a clogged filter, a kinked drain hose or a blocked garbage disposal inlet, or a drain pump that has failed.

4C (4E on some models) means the dishwasher isn't getting enough water. With the valve under the sink open, the usual causes are a failed water inlet valve, a kinked supply line, or a flood-stop hose that has shut itself off.

HE (HC on some models) is a heater error: the water isn't heating as expected. The usual causes are a failed heating element, a temperature sensor, or the control board.

AE means the leak sensor detected water in the base. The usual causes are a leaking sump or pump seal, a worn door gasket, or suds from dish soap or too much detergent.

bE means too many bubbles, almost always from hand dish soap or too much detergent. If it keeps coming back with the right detergent, a slow drain pump or a faulty sensor can be the cause.

OE means the dishwasher couldn't drain. The usual causes are a clogged filter, a kinked or blocked drain hose, or a drain pump that has failed.

IE means water isn't coming in. With the valve under the sink open, the usual causes are a failed water inlet valve, a kinked supply line, or a stuck float switch.

LE means the wash (cleaning) motor isn't running normally. The usual causes are debris jamming the motor's impeller, a failed wash motor, or its wiring.

HE means the water isn't heating. The usual causes are a failed heater, a heater circuit fault, or the control board.

tE is a temperature sensor error. The usual causes are a failed temperature sensor, its wiring, or the control board.

CL isn't a fault: Control Lock is on, so the buttons don't respond. Press and hold the button marked with the lock symbol for about 3 seconds to unlock.

E24 means water isn't draining away. The usual causes are clogged filters, a kinked drain hose or a blocked garbage disposal inlet, or a drain pump that has failed.

E25 means the drain pump is blocked. The usual causes are glass, a seed or a label caught in the pump, a pump cover that's loose, or a drain pump that has failed.

E22 means the filter is blocked. If cleaning it doesn't clear the code, the usual causes are a slow drain pump or a damaged filter.

E15 means water got into the base, and the leak protection has stopped the dishwasher. The usual causes are a leaking pump seal or internal hose, a worn door seal, or heavy suds. (Thermador dishwashers use the same code.)

E09 is a heating error. The usual causes are a failed heat pump (the circulation pump with the built-in heater), its wiring, or the control module.

E14 points to the flow meter, which measures incoming water. The usual causes are a failed flow meter, a water inlet valve that lets in too little water, or low water pressure.

E21 means the circulation (heat) pump is blocked. The usual causes are glass, a seed or a label caught in the pump, or a pump motor that has failed.

i20 means the dishwasher isn't draining. The usual causes are clogged filters or sump, a blocked drain hose (or the knockout plug left in a new garbage disposal), or a drain pump that has failed.
