Bosch Dishwasher Error Code E25: How to Fix It

The Logic Verdict

I watched the host bail the nasty standing water with a mug, twist the lower filter stack free, then follow Bosch’s own advice of prying the white impeller cover off with a spoon. A tomato stem was wedged between the blades. Replicate that order: clear the water, expose the drain pump, and feel for hard debris before assuming the pump or electronics failed.

What It Means

E25 fires when the control energizes the drain pump but flow never starts. That usually means the sump cover isn’t sealed or the impeller cavity is physically blocked, so the motor just cavitates and the tub stays full.

Common Causes

1. Impeller jammed with food scraps: Tomato stems, labels, or plastic film stop the rotor exactly like the video shows.
2. Pump cover loose or missing: Without that white cap, the pump can’t build pressure and the code returns instantly.
3. Filter stack packed with grease: Dirty filters keeps sludge circulating back into the pump well.
4. Downstream restriction: A kinked or clogged drain hose after the pump will mimic a seized impeller.

Step-by-Step Fix

1. Kill power and bail the sump: Cancel the cycle, unplug the dishwasher, and scoop water into a bowl until you can see the filter housing.
2. Remove spray arm and filters: Lift the lower spray arm out, twist the cylindrical filter counter-clockwise, and rinse everything under hot water.
3. Vacuum the last puddle: Use a turkey baster or shop vac just like the host so no leftover water rushes into the pump cavity when you open it.
4. Pry the impeller cover: Following the manual callout, slip a spoon under the white cover’s tab and lift it straight up to reveal the impeller.
5. Clear the obstruction: Rotate the impeller with your fingertips and pull out any stems, glass, or plastic until it spins freely.
6. Reassemble and test: Snap the cover back on, reinstall the filter stack and spray arm, restore power, and start a quick cycle. The dishwasher should drain immediately before filling.
