Drying cycle stops with E12; poor drying performance and possible water not being pumped from condenser.

Safety first: Unplug the appliance. Expect residual water in the condenser sump; use towels.

Step-by-step checks:

• Access condenser area: Remove the lower front panel or rear panel (depending on model) to reach the condenser sump and pump.
• Clear blockages: Remove any lint, hair, or debris from the sump, pump inlet, and outlet channels. Ensure water can flow freely.
• Test the pump: Disconnect the pump and measure coil resistance. If open circuit, replace the pump. You can also briefly power the pump with a safe test supply (by a qualified person) to confirm operation.
• Check level sensor (if fitted): Some models use a float or electronic sensor in the sump. Ensure the float moves freely and the sensor is clean.
• Reassemble and test: Refit all parts and run a drying cycle to confirm that water is being pumped and E12 does not reappear.

When to call a technician: If the pump and sump are clear but the error persists, the control board or sensor circuit may be faulty and requires professional service.
