Bosch Dishwasher E25: Drain Pump Blocked or Pump Cover Loose (Meaning, Causes, Fixes)

Reviewed 2026-10-22 · Based on 5 manufacturer & service sources

What the code means

Bosch USA says an E25 error code indicates the drain pump is blocked or the drain pump cover is loose or missing. Bosch's owner's manual lists E25 under "water is left in the appliance at the end of the programme" as "waste water pump blocked, cover on the waste water pump is not locked in position," and explains that large food remnants that get past the filters can block the pump so the rinse water isn't pumped out and covers the filter. Bosch Saudi Arabia and Malaysia describe it the same way: the pump is blocked with foreign objects or the pump cover isn't attached correctly. Its sibling E24 points at a blocked or kinked drain hose instead; both leave standing water in the tub, so if E25 clears but the water still won't drain, work through the E24 checks too.

Likely causes

Safe DIY checks

⚠ Before you start

Unplug the appliance (or switch off its breaker) and shut off the water supply valves before removing panels or disconnecting hoses. Keep towels handy for residual water.

  1. Turn the dishwasher off and unplug it or switch off its breaker. Bosch warns the pump may be blocked with glass fragments, so be careful of cuts; let any hot water cool first.
  2. Remove the filter system from the bottom of the tub and scoop or sponge out the standing water.
  3. Find the drain pump cover under the filter. Using a spoon, pry the cover up until it clicks, grip it by the tab, pull it upward until it resists, then pull it forward to remove it, as Bosch's manual and support page describe.
  4. Remove all foreign objects and debris from the pump chamber. Check that the pump impeller can be rotated freely.
  5. Put the pump cover back in its original position, press it down until it clicks and locks (some models screw it tight). An unlocked cover by itself can trigger E25.
  6. Rinse the coarse, fine, and micro filters under running water, then reinstall them so they're seated correctly.
  7. Restore power, reset the dishwasher per your owner's manual, and run a rinse or drain program to confirm the water clears. If it still won't drain, check the drain hose, sink connection, and garbage-disposal knockout plug (the E24 checks).

🛠 When to call a pro

  • E25 comes back after the pump chamber is clear, the impeller spins freely, and the cover is locked.
  • The impeller is broken, won't turn even with debris removed, or the pump hums without moving water.
  • The pump cover is cracked, missing, or won't lock in place.
  • You'd need to pull the dishwasher out of the cabinet to reach or replace the drain pump.
  • Bosch's advice if the steps don't solve it is to contact Bosch Customer Support (1-800-944-2904 in the US) or book an engineer.
