Bosch dishwasher — Error Code E25

What it means

The E25 error code on a Bosch dishwasher is a direct indication of a drain pump fault, specifically that the pump is blocked or the protective pump cover is missing or improperly seated. Bosch dishwashers utilize a BLDC (Brushless Direct Current) drain pump. The main control board monitors the electrical current drawn by this pump. If debris jams the impeller, the motor draws excess current, prompting the board to halt the cycle and throw the E25 code to prevent motor burnout. Alternatively, the drain pump cover (a small white plastic piece inside the sump) is crucial for directing water flow over the impeller. If this cover is loose or removed during cleaning and not replaced, the pump cannot create the necessary suction to evacuate the water, causing the board to detect a no-load or abnormal load condition. This fault halts the draining phase, leaving standing water in the tub.

Likely Causes

1. 1
   Jammed Drain Pump Impeller

   Glass shards, popcorn kernels, or bone fragments bypass the filter and physically jam the BLDC pump impeller, causing a high-current draw at the control board.
2. 2
   Missing or Loose Pump Cover

   The white plastic drain pump cover inside the sump must be snapped firmly into place. Without it, the pump cavitates and cannot push water into the drain hose.
3. 3
   Clogged Filter Assembly

   A severely restricted mesh filter prevents water from reaching the pump, triggering abnormal load readings and preventing proper evacuation.
4. 4
   Obstructed Drain Hose or Air Gap

   A kinked drain hose, clogged sink air gap, or a blocked garbage disposal knockout will cause back-pressure, stalling the pump and triggering the code.
5. 5
   Failed Drain Pump Motor

   Though less common than a physical jam, the BLDC drain pump windings can fail, or the rotor can seize, requiring a full pump replacement.

How to clear / reset

To clear the E25 code, you must first resolve the underlying blockage. Disconnect power, remove the bottom rack, and pull out the cylindrical filter. Bail out any standing water. Remove the white plastic drain pump cover (pulling it up and out with a spoon or removing the Torx T20 screw, depending on the model). Inspect the impeller for debris and ensure it spins freely. Snap the pump cover securely back into place—this is critical. Restore power, then press and hold the 'Start' button for 3 to 5 seconds to initiate a hard reset. The display should read '0:01'. Close the door, wait for the drain cycle to complete (it will change to '0:00'), and turn the unit off.
