Bosch E01 Error Code: Troubleshooting Heating Element Problems
Updated: February 2026
When your Bosch dishwasher shows E01 , it indicates the heating element isn't working properly. This means your dishes won't get hot water for effective cleaning and sanitizing.
Understanding the E01 Code
The heating element heats water to the optimal temperature for dissolving detergent and removing grease. When it fails or the thermistor malfunctions, the E01 error appears. This could also indicate wiring issues or a faulty control board.
Troubleshooting Steps
- Step 1: Unplug the dishwasher and turn off the circuit breaker for complete electrical safety.
- Step 2: Access the heating element by removing the lower front panel and then the lower spray arm and filter assembly.
- Step 3: Use a multimeter to test the heating element for continuity. Set the meter to ohms and touch the probes to the element terminals. A reading of 15-30 ohms indicates a working element; infinite resistance means it's faulty.
- Step 4: Check the thermistor (temperature sensor) with the multimeter. It should show resistance that changes with temperature.
- Step 5: Inspect all wire connections to the heating element for corrosion or loose terminals.
- Step 6: If the element tests bad, order a replacement specific to your Bosch model number.
Replacing a heating element requires moderate DIY skills. If you're uncomfortable working with electrical components, contact a qualified appliance technician. Remember to always prioritize safety when working with electrical appliances.
