Top 5 Bosch Washing Machine Error Codes and How to Fix Them

Bosch washing machines are built with German precision, but even the best appliances can encounter faults. When an error code appears, it’s your machine’s way of telling you exactly what’s wrong. Here are the five most common Bosch washing machine error codes—and how to resolve them.

1. E18 / F18 – Drainage Problem

What it means: The washing machine is not draining water. This can be caused by a blocked or kinked drain hose, or a clogged pump filter.

How to fix it:

  • Turn off the appliance and unplug it.

  • Check the drain hose for any kinks or blockages.

  • Open the service flap, drain residual water, and clean the pump filter thoroughly. Ensure the pump’s impeller wheel can spin freely.

  • Reassemble and run a drain cycle to test.

If cleaning the pump doesn’t resolve the issue, you may need a technician to check the drain pump.

2. E24 – Pump Blocked

What it means: This code indicates a blockage in the pump or drain system, preventing water from being pumped out properly.

How to fix it:

  • Unplug the machine and access the pump filter through the service flap.

  • Remove any debris (coins, lint, buttons) from the pump housing.

  • Check that the pump cover is securely fastened.

  • Restart the machine to see if the error clears.

Note: On some models, E24 may also point to a loose pump cover, so ensure it’s tightened correctly.

3. E15 / F15 – Water Leakage Detected

What it means: The water protection system has been activated, meaning water has been detected in the base of the appliance.

How to fix it:

  • Important: Turn off the water tap immediately and do not attempt to run the machine.

  • Check around the machine for visible leaks or damaged hoses.

  • If you find no obvious external leaks, the issue may be internal.

Warning: Bosch recommends not trying to resolve this issue yourself due to health and safety risks. Call a qualified technician to inspect and repair the leak.

4. E32 / F32 – Unbalanced Load

What it means: The washing machine has detected an imbalance during the spin cycle. The drum will either slow down or stop spinning to prevent damage to the appliance.

How to fix it:

  • Pause the cycle and redistribute the laundry evenly inside the drum.

  • Wash large and small items together in the same load to help balance the drum.

  • Check that zippers and buttons on heavy items are closed.

  • Restart the spin cycle.

If the error persists, the machine may have internal suspension or bearing issues requiring professional attention.

5. E23 / F23 – AquaStop Hose Activated

What it means: The AquaStop safety hose has detected a leak and has been activated.

How to fix it:

  • Turn off the water tap immediately.

  • Inspect the AquaStop hose for visible damage or kinks.

  • If the hose appears damaged, it will need replacement by a professional.

Warning: This error cannot be corrected on your own. Contact a certified Bosch technician to replace the hose and check for further water damage.
