The E31 error code in Bosch dishwashers indicates a problem with the water supply. This can be caused by various factors, ranging from a clogged filter to a faulty water valve. Understanding the causes of the E31 error code is crucial for effective troubleshooting.
Troubleshooting the E31 Error Code
1. Check the Water Supply
- Ensure that the water supply is turned on and that there is adequate water pressure.
- Inspect the water inlet hose for kinks or blockages. Clean or replace the hose if necessary.
2. Clean the Water Filter
- Locate the water filter inside the dishwasher and remove it.
- Rinse the filter thoroughly under running water to remove any debris or buildup.
- Reinstall the clean filter securely.
3. Inspect the Drain Hose

- Ensure that the drain hose is properly connected to the drainpipe.
4. Test the Water Inlet Valve
