Bosch Dishwasher E25 Error: Drain Pump Blockage Removal
Updated: February 2026
The Bosch E25 error code appears when your dishwasher's drain pump is blocked or unable to pump water out effectively. This results in standing water and interrupted wash cycles.
Common Causes of E25
Foreign objects like broken glass, food particles, twist ties, or small utensils can lodge in the drain pump impeller. Grease and soap buildup can also restrict pump operation over time. The pump may run but can't move water efficiently.
Complete Blockage Removal Guide
- Step 1: Cancel the cycle and disconnect power. Remove standing water with a cup or wet vacuum to make work easier.
- Step 2: Remove the lower dish rack, then unscrew and lift out the spray arm.
- Step 3: Take out the filter assembly by turning the cylindrical filter counterclockwise. Remove the flat filter underneath.
- Step 4: Look into the sump area where the pump impeller is visible. Remove any debris you can see and reach.
- Step 5: For deeper access, tilt the dishwasher back carefully and remove the bottom panel. Locate the drain pump (usually on the left side).
- Step 6: Disconnect the drain pump by loosening hose clamps and unplugging the electrical connector. Remove the pump assembly.
- Step 7: Disassemble the pump cover and remove the impeller. Clean thoroughly and check for damage. Replace if blades are broken.
Reassemble the pump, reconnect hoses and wiring, and test operation. The E25 error should clear once the pump runs freely. Prevent future blockages by scraping dishes well and running hot water in the sink before starting the dishwasher to soften grease.
