Code E25
high severity
Bosch models: Bosch dishwashers have a three-stage filter: coarse screen, flat micro-filter, and cylindrical fine filter under the lower spray arm. Remove and clean all three together. Bosch drains actively using a pump — any standing water in the sump at mid-cycle is a blockage indicator, not normal residual water.
Common causes
- Hard object (cherry pit, broken glass, toothpick) jammed in the drain pump impeller
- Pump impeller broken
Step-by-step fix
- Remove the filter assembly and spray arm.
- Reach down into the sump and feel for the pump impeller — try to turn it by hand.
- Use needle-nose pliers to remove any obstruction.
- If the impeller spins freely after clearing, run a drain cycle to confirm.

Prevention
- Do not wash items with small loose parts (toothpicks, olive pits) in the dishwasher.
- Clean the filter monthly to prevent debris reaching the pump.
When to stop DIY
If the impeller is broken or the pump motor hums without spinning, the pump assembly needs replacement.
