AEG Washer Error Code C2

The C2 code indicates a fault in the drain system or water level sensing circuit. It can mean the drain pump is blocked by a foreign object, the pump has reduced performance or has failed entirely, or the pressure sensor or pressure switch is defective. The washer displays this code when it cannot confirm that the drum has drained within the expected time frame.

A reset may temporarily clear the C2 code from the display, but the error will return as soon as the washer attempts to drain again if the underlying cause has not been addressed. Resetting without fixing the blocked pump, faulty drain hose, or defective pressure sensor is not a lasting solution.

If the fix is simply clearing a blocked pump filter or removing a foreign object, the repair can cost nothing beyond your time. Replacing a drain pump typically involves parts and labor costs ranging from around $100 to $250 depending on your location and the specific pump required. Replacing a pressure sensor or pressure switch is generally a lower-cost repair, with parts and labor often falling in the $75 to $175 range.

Start by cleaning the pump filter, located behind the small access panel at the lower front of the machine, and remove any foreign objects you find. Next, check the drain hose for kinks or blockages. If the drain path is clear and the error persists, the pump itself or the pressure sensor may need to be replaced. Addressing the physical blockage or component failure is required to clear the fault permanently.

It is not recommended to continue running the washer while C2 is active. If the machine cannot drain properly, water can remain in the drum and potentially overflow or cause damage to internal components over time. Stop using the appliance and diagnose the drain system before running another cycle.
