Drain Pump Blocked

What it means

This code appears on Bosch dishwashers when the drain pump is obstructed by a trapped object such as a piece of glass, a bone, a fruit stone or a label. The program stops and water stays in the bottom. The Bosch user manual explains how to open the pump cover under the filters and clean it after unplugging, and the same number can mean something else on other brands.

Models covered: Bosch dishwashers; the code shows on the display or at the end of a program.

Symptoms4

• E25 shows and the program stops with water left in the bottom.
• Rattling or loud humming from under the unit while draining.
• Draining works sometimes and fails other times.
• The code keeps returning after washing jars with labels or items with hard debris.

Possible causes5

• A hard object stuck in the pump impeller, such as a glass shard, bone or fruit stone.
• Blocked or badly fitted filters that let debris reach the pump.
• Paper labels from jars or new dishes that dissolved and reached the pump.
• A blocked drain hose putting load on the pump.
• A faulty drain pump.

How to diagnose5

1. Unplug the unit, remove the lower basket, then take out and clean the filters.
2. Scoop out remaining water until the pump cover is visible.
3. Open the pump cover as the user manual explains (often by levering the tab with a spoon) and remove any object carefully, as it may contain sharp glass.
4. Check the impeller turns freely, then refit the cover until it clicks, followed by the filters.
5. If the code remains, a technician unplugs the unit before taking it apart and checks the pump, its wiring and the hose.

How to fix5

1. Clear the pump of trapped objects and refit its cover.
2. Clean the filters regularly and make sure they are fitted correctly.
3. Remove paper labels before washing and scrape off hard debris.
4. Have the technician replace the drain pump if damaged.
5. Run a short program and confirm full draining without the code.
