The E11 error on your Hoover Dishwasher means there is a heating fault or the water is not reaching the correct temperature. This typically indicates a problem with the heating element, thermostat, or related wiring preventing proper water heating during the wash cycle.
| Error code | E11 |
|---|---|
| Meaning | Heating system fault - water not heating correctly |
| Severity | Medium — Dishwasher may complete cycle but with poor cleaning results |
| Time to fix | 20–60 minutes |
| Tools needed | Multimeter, screwdriver set, pliers |
What the E11 error means
The E11 error code signals that your Hoover dishwasher has detected a problem with the heating system. The appliance monitors water temperature during the wash cycle and triggers this error when the water fails to reach the required temperature within a set timeframe. This can result from a faulty heating element, defective thermostat, or issues with the electronic control board that regulates heating functions.
Common causes
- Faulty or burnt-out heating element that cannot warm the water
- Defective thermostat or temperature sensor providing incorrect readings
- Loose or corroded electrical connections to the heating element
- Limescale buildup on the heating element reducing efficiency
- Faulty control board or PCB not sending power to the heating system
- Damaged wiring harness between the heating element and control board
How to fix the E11 error
- Reset the dishwasher: Turn off the dishwasher at the mains power for 10-15 minutes to reset the control board. Switch it back on and run a test cycle to see if the error clears. If the error persists, proceed with further diagnostics.
- Check the heating element: Disconnect power and access the heating element at the base of the dishwasher tub. Use a multimeter to test for continuity - a working element should show 20-30 ohms resistance. If there is no continuity or infinite resistance, the heating element has failed and needs replacement.
- Inspect electrical connections: Examine all wire connections to the heating element and thermostat for looseness, corrosion, or burn marks. Clean corroded terminals with contact cleaner and ensure all connections are tight and secure. Replace any visibly damaged wires.
- Test the thermostat: Locate the thermostat attached to or near the heating element. Test it with a multimeter for continuity at room temperature - it should show continuity when cold. If the thermostat is open circuit or stuck, replace it with a genuine Hoover part.
- Descale the heating element: If the element tests functional but has heavy limescale buildup, run an empty cycle with a dishwasher descaler or white vinegar. For severe buildup, carefully remove loose scale with a plastic scraper, being careful not to damage the element.
- Check the control board: If all heating components test correctly, the issue may be with the main control board not supplying power to the heating system. This requires professional diagnosis and replacement if faulty, as control boards contain complex electronics.
FAQ
Can I still use my Hoover dishwasher with the E11 error?
You can technically run the dishwasher, but it will not heat the water properly. This results in poor cleaning performance, as hot water is essential for dissolving detergent and removing grease. It is best to fix the error promptly for optimal results.
How much does it cost to fix an E11 error on a Hoover dishwasher?
A replacement heating element typically costs between £25-£60, while a thermostat costs £10-£25. If you hire a professional, expect labour costs of £60-£100 on top of parts. Control board replacement is more expensive at £80-£150 for the part alone.
How can I prevent the E11 error from happening again?
Use dishwasher salt regularly if you live in a hard water area to prevent limescale buildup on the heating element. Run a maintenance wash with dishwasher cleaner monthly and avoid overloading the appliance. Ensure proper drainage after each cycle to prevent standing water around electrical components.
