The E15 error code on your Bosch dishwasher means there’s water in its base. This activates the safety switch and triggers flood protection mode. The dishwasher stops as a precaution. It’s time to fix the issue to prevent damage to your appliance and kitchen.
Why Does the E15 Error Code Appear?
Common causes behind the Bosch dishwasher E15 error include:
- Water Leakage: Often, water in the base pan triggers the E15 error. This water might accumulate from an internal leak or from using too much detergent.
- Control Board Glitch: A glitch in the control board can, at times, mistakenly show the E15 error.
- Blocked Spray Arms or Sump Basin: If blocked, spray arms may misdirect water. This can cause pooling in unintended areas.
- Leaking Hoses or Tank: Over time, hoses or even the water tank might develop leaks that need to be repaired.
How to Fix Bosch Dishwasher Error Code E15
If the E15 error shows up, here are the main steps to resolve it safely and effectively.
1. Perform a Hard Reset
A simple hard reset can sometimes clear the E15 error, especially if it’s caused by a temporary glitch:
- Disconnect the power from your dishwasher for at least five minutes.
- Reconnect the power, and see if the error has disappeared.
A hard reset can clear control board issues. If the error code remains, more troubleshooting may be needed.
2. Try the Tilt Method
Another quick solution is the tilt method to drain any excess water from the base pan. Here’s how:
- Pull the dishwasher carefully from under the counter.
- Tilt it backward at a 45-degree angle.
- Make sure to place a towel underneath to catch any water that spills out.
- Reconnect the power and check if the error has cleared.
This method isn’t a permanent fix but can help temporarily by draining excess water from the base pan.
3. Access and Reset the Water Level Safety Switch
If the E15 error persists, accessing the water level safety switch may be necessary. Here’s what to do:
- Turn off the power and water supply to the dishwasher.
- Use a T20 or T15 Torx screwdriver to remove the outer door panel and kickplate.
- Locate the safety switch inside the base near the polystyrene disk.
Once you’ve accessed the base:
- Remove the polystyrene disk and dry it thoroughly.
- Mop up any remaining water in the basin using a towel.
- Check for debris or obstructions, then reposition the safety switch and disk.
This should reset the safety switch and clear the E15 error code.

Sometimes, despite your best efforts, the E15 error persists. In this case, it may be best to contact a professional technician if:
- There is persistent water leakage or signs of damage.
- Wiring or parts appears damaged. A technician will have the tools to replace or repair parts safely.

Professional repair costs can vary. So, consider this when deciding on Bosch dishwashers.
