Bosch Dishwasher E25 Error Code: Causes and Safe Checks

Where to find the drain pump cover

Bosch locates the drain pump beneath the filter at the bottom of the dishwasher. The filter and the pump cover are separate parts, so cleaning the filter alone does not confirm that the cover is secure or the pump is clear.

Find the owner’s manual using your appliance’s E-Nr. Check the pump-access diagram before removing anything: Bosch describes both clip-in covers and designs with a screw fastening. A release method shown for a different dishwasher may not match yours.

How to check the pump cover

With the power disconnected, remove the filter as directed and locate the cover. Look for a cover that is absent, sitting out of position or not properly fastened. Use the manual’s illustration to identify the correct position.

If the cover is present but loose, follow the specified refitting procedure. Avoid improvising a fastening or treating a missing cover as an optional part; Bosch specifically includes it in the E25 checks.

How to check for a blocked drain pump

Bosch warns that broken glass and other sharp objects can collect around the pump. Its pump-cleaning guidance recommends protective gloves when removing residual water and working in this area.

If the manual permits access, work through its cleaning procedure:

• Remove standing water with a sponge or by carefully scooping it out.
• Release the pump cover using the method shown for your model.
• Inspect the exposed area for foreign objects and remove accessible debris carefully.
• Check the impeller as directed; Bosch’s guidance calls for it to move freely.

Some Bosch instructions show a spoon releasing the cover; other designs use a manual screwdriver. The manufacturer expressly rules out an electric screwdriver for that cover-removal method. If the fastening is unclear or access cannot be completed safely, stop and ask Bosch support for help.

Refit the cover and filter before use

Put the cover back in its specified position and secure it fully. Depending on the design, that may mean engaging a clip or tightening a screw. Then reinstall the filter correctly and replace any baskets removed for access.

The Australian manual’s E25 entry pairs pump cleaning with locking the cover correctly. Follow your own manual’s operating instructions before using the dishwasher again.

If the message returns

Bosch directs owners who need further assistance to customer support. Use the service channel for your country and explain which checks you completed. If cleaning and correct refitting have not resolved E25, further diagnosis is more useful than repeating the same procedure.

Have the following details ready:

• The full E-Nr and FD production number from the appliance’s rating plate.
• The exact display message, including any punctuation or additional digits.
• Whether water remained in the dishwasher and what you found beneath the filter.
• Whether the cover was loose, missing or refitted, and whether the message returned afterward.

The model and production numbers help Bosch identify the appliance. The remaining observations give the service team a clear account of what has already been checked.
