Bosch dishwasher code E25: drain pump blocked or pump cover loose

What it means

Something is blocking the drain pump, or the pump cover under the filter is loose. Bosch’s manual describes this as not an appliance fault.

On models without a display, Bosch signals this with: four lights flashing, or the Active and Clean lights flashing.

What to try

Unplug the dishwasher before any step beyond a quick look, and turn the water off before touching hoses.

1. Disconnect the dishwasher from power: unplug it, or switch off its breaker if it’s hardwired.
2. Take out the upper and lower racks, then remove the filter system.
3. Scoop out any standing water, using a sponge if you need to.
4. Pry the pump cover off with a spoon, gripping it by the crosspiece, and lift it out at an angle.
5. Carefully remove any food or objects around the impeller underneath. Bosch warns there may be sharp debris such as broken glass.
6. Press the pump cover back down until it clicks into place, then refit the filters and racks.
7. Check the drain hose under the sink for kinks or sharp bends.

Resetting a Bosch dishwasher

Once you’ve fixed the cause, Bosch’s way to cancel the cycle and clear the code is to press and hold Reset (Start on some models) for about 4 seconds. The dishwasher pumps out the water, which takes about a minute; then open the door and press On/Off. For electronic faults, Bosch’s code list says to switch the dishwasher off at its breaker for 30 seconds. If four lights flash and it beeps, Bosch says to press On/Off, switch off the power for at least 2 minutes, then switch it back on; if it happens again, press On/Off, turn off the water, unplug it and call Bosch.
