Frequently Asked Questions
Common questions about Bosch E25 error
E25 means something hard is jammed in the drain pump impeller — usually a piece of broken glass, a fruit pit, or a packaging label. Put on rubber gloves, remove the filter assembly, and use a flashlight to inspect the pump cavity beneath it. Carefully pull out whatever is blocking the impeller, and the error should clear on the next cycle.
The E22 error is caused by a clogged filter, the E24 by a blocked drain hose, and the E25 specifically by a foreign object physically blocking the drain pump impeller inside the machine. Each requires a different fix: clean the filter for E22, clear the drain hose for E24, and remove the blockage from the pump cavity for E25.
