The E25 error code on a Bosch dishwasher is an indication of a problem with the dishwasher’s drainage system. Specifically, it suggests that the pump filter is blocked, preventing the dishwasher from effectively draining water during the wash cycle. When the pump filter is clogged with debris, dirt, or food particles, it hinders the flow of water and can lead to issues like water not draining properly, dishes not coming out clean, or even the dishwasher not completing its cycle.

Regular maintenance and cleaning of the pump filter can help prevent this error from occurring and keep your dishwasher running smoothly.

Common causes behind this issue and guide you through the troubleshooting process to get your dishwasher up and running again. Here are the main culprits of the E25 error:

1. Blocked Pump Filter: The most common cause of the E25 error is a blocked pump filter. The filter traps food debris and prevents it from clogging the drainage system. Over time, the filter can get filled with gunk, leading to drainage problems.

2. Clogged Waste Water Pump: The waste water pump propels the drained water out of the dishwasher. If it gets clogged with debris or foreign objects, the water won’t drain properly, triggering the E25 error.

3. Drainage Hoses and U-Bend Blockage: Sometimes, the drainage hoses or the u-bend, which connects to the sink’s plumbing, can get blocked by food particles or other obstructions. This can disrupt the dishwasher’s drainage process.
