Kinked drain hose
Faulty drain pump motor

Tools You'll Need

Pliers Soft Brush Towels / Bucket Flashlight

Most of these fixes need only basic hand tools. If your repair requires opening electrical housings or testing live components, a multimeter and basic electrical safety knowledge are essential — when in doubt, call a technician.

Technical Explanation

Bosch's EGO module monitors drain pump motor current via a shunt resistor. A blocked impeller causes a current spike; a failed motor shows zero current. Both conditions cause the module to time out the drain cycle and post E25.

Is It Safe to Keep Using?

Fix today. Standing water develops bacteria and odor, and the machine cannot be safely used until draining is restored.

Technician's Pro Tip

After cleaning the filter, manually spin the pump impeller through the sump opening with your finger to verify it rotates freely. If it is jammed or gritty, rinse with water. If it spins freely but machine still doesn't drain, the pump motor is the culprit.
