If your Bosch washing machine is displaying the E25 error code, it means the drain pump is struggling to remove water from the drum. This error prevents proper drainage and often leaves clothes soaking wet at the end of a cycle. While it may sound serious, the E25 error is usually caused by a simple obstruction that you can often clear yourself.

What does the E25 error mean?

The E25 error appears when the washer detects that water is not being pumped out efficiently. Most often, the problem lies with the drain pump impeller, pump filter, or drain hose being blocked by debris. When water cannot flow freely through the drainage system, the washer stops the cycle to prevent damage.

If left unresolved, the issue may cause standing water in the drum, incomplete cycles, and potential strain on the pump motor.

Common causes of the E25 error

• Debris in the Pump Impeller

  Small objects like coins, buttons, or lint can jam the pump’s rotating blades, stopping it from working.

• Clogged Drain Hose

  Kinks or blockages in the hose restrict water flow.

• Blocked Pump Filter

  If the filter hasn’t been cleaned regularly, trapped lint and fabric debris can block drainage.

• Soap Scum or Detergent Residue

  Excess detergent buildup can narrow the drain path, slowing water flow.

• Foreign Objects in the Drain Path

  Hairpins, socks, or other small items may lodge inside the filter housing or hose.

How to fix the E25 error

Follow these steps to troubleshoot safely:

• Unplug the Washer

  Always disconnect power before working on the machine.

• Open the Pump Filter Access Panel

  Usually located at the bottom front of the washer.

• Clean the Pump Filter

  Place a towel and shallow tray beneath the washer. Slowly unscrew the filter cap to release trapped water. Remove lint, coins, or other objects.

• Check the Drain Hose

  Detach the hose and rinse it through to clear blockages. Ensure it’s not bent or kinked.

• Inspect the Pump Impeller

  With the filter removed, look inside for stuck objects. The impeller should rotate freely.

• Restart the Washer

  Plug the washer back in and run a short cycle to test drainage.

⚠️ If the error reappears after cleaning, the pump motor may be damaged and require replacement.

When to call a technician

Professional service is needed if:

• The pump makes grinding noises or doesn’t turn even after cleaning.
• Water remains in the drum despite checking hoses and filters.
• The pump or impeller is visibly damaged.

A certified Bosch technician can test the pump motor, wiring, and control board. If necessary, they can replace the faulty pump to restore full functionality.

Conclusion

The Bosch washer E25 error signals a blocked drain pump, usually caused by debris, a clogged hose, or a dirty filter. In most cases, you can resolve it with basic cleaning and inspection. However, if the pump is damaged or the error persists, calling a professional ensures safe and lasting repairs. Regular filter cleaning and careful laundry habits will help prevent this issue in the future.
