Bosch Dishwasher E25 Error Code — What It Means
E25 points straight at the drain pump. Either the pump cover is loose or missing, or something is jamming the impeller so it cannot push water out.
This often shows up right after an E22 or E24 drain problem, when debris settles into the pump chamber. Clearing the impeller usually fixes it.
Common Causes
- Loose or missing pump cover The impeller cover sits under the filter and the pump cannot run if it is not locked in place.
- Jammed impeller A seed, label, or shard of glass wedges the impeller and stops the pump from turning.
- Stuck non-return valve The plastic check valve flap sticks and blocks water from leaving the pump.
- Debris deep in the pump chamber Food and grit settle below the impeller where you cannot see it from above.
- Failed drain pump A worn pump motor grinds or stays silent and cannot move water out of the sump.
Step-by-Step Fix
- Turn off the breaker and remove the lower rack to reach the bottom of the tub.
- Twist out the filter, then lift off the drain pump cover under it.
- Reach into the pump opening and clear any debris, then spin the impeller to confirm it turns freely.
- Check the small plastic non-return valve flap and make sure it moves and seats on its own.
- Seat the pump cover firmly so it locks, reinstall the filter and rack, then restore power.
- Run a rinse cycle and listen for a steady drain to confirm E25 clears.

When to Call a Pro
If the impeller is clear and the cover seats but E25 returns, the pump motor is likely failing. Replacing the drain pump means pulling the unit and reaching the sump, so call a technician if that is beyond your comfort.
