The E13 error on your Hoover Dishwasher means there is a water heating problem or the heating element has failed. This error typically appears when the dishwasher cannot heat water to the required temperature within the expected time frame.
| Error code | E13 |
|---|---|
| Meaning | Water heating fault or heating element failure |
| Severity | Medium — Dishes may not clean properly without hot water, but the dishwasher is not at immediate risk |
| Time to fix | 20–60 minutes |
| Tools needed | Multimeter, screwdriver set, socket wrench, towels |
What the E13 error means
The E13 error code indicates that your Hoover dishwasher is experiencing a problem with heating the water. The dishwasher monitors water temperature during the wash cycle and expects the water to reach a specific temperature within a set time period. When the heating element fails to raise the water temperature adequately, or when the control board detects an issue with the heating circuit, the E13 error is triggered and the cycle stops.
This fault prevents the dishwasher from completing its wash programme because hot water is essential for dissolving detergent properly and removing grease and food particles. The error can be caused by a faulty heating element, a defective temperature sensor, wiring problems, or issues with the control board that manages the heating function.
Common causes
- Faulty or burned-out heating element that no longer generates heat
- Defective NTC thermistor or temperature sensor providing incorrect readings
- Loose, corroded, or damaged wiring connections to the heating element
- Limescale buildup on the heating element reducing its efficiency
- Malfunctioning control board not sending proper signals to the heating element
- Tripped thermal cutout or safety fuse protecting the heating circuit
How to fix the E13 error
- Reset the dishwasher and check for simple issues Turn off the dishwasher at the mains power for five minutes, then restart it. Try running a short cycle to see if the error clears. Check that the water supply is working properly and that the inlet filter is not blocked, as insufficient water can trigger heating errors.
- Test the heating element with a multimeter Disconnect the power supply completely. Access the heating element by removing the lower panel or side panels of the dishwasher. Disconnect the wires from the heating element terminals and use a multimeter set to resistance mode. A working element typically shows 15-30 ohms of resistance. If the reading shows infinite resistance or zero, the element is faulty and needs replacement.
- Inspect and test the temperature sensor Locate the NTC thermistor, which is usually near or attached to the heating element. Disconnect it and test with a multimeter at room temperature, which should show around 12,000 ohms at 25°C. If the reading is significantly different or shows no continuity, replace the temperature sensor.
- Check all wiring and connections Examine all wires connected to the heating element and temperature sensor for signs of damage, burning, corrosion, or loose connections. Clean any corroded terminals with fine sandpaper and ensure all connections are tight and secure. Replace any damaged wiring.
- Remove limescale from the heating element If the heating element appears heavily coated with limescale, this can reduce heating efficiency. Remove the element if possible and soak it in a descaling solution or white vinegar for several hours. Scrub gently with a soft brush and rinse thoroughly before reinstalling. Alternatively, run an empty cycle with a dishwasher descaling product.
- Replace the faulty component or contact a technician If you have identified a faulty heating element or temperature sensor, order the correct replacement part for your specific Hoover dishwasher model. If you are uncomfortable with electrical repairs or the control board appears to be faulty, contact a qualified appliance repair technician to safely diagnose and fix the problem.
FAQ
Can I still use my Hoover dishwasher with the E13 error code?
You should not continue using the dishwasher when it displays the E13 error. While the appliance may start a cycle, it will not heat the water properly, resulting in poor cleaning performance. Dishes will not be sanitized adequately, and the cycle may stop mid-programme. Continuing to use the dishwasher with a faulty heating element could also cause additional damage to other components or create an electrical safety hazard.
How much does it cost to fix an E13 error on a Hoover dishwasher?
The cost depends on the specific fault. A replacement heating element typically costs between £20 and £60, while a temperature sensor costs £10 to £25. If you hire a professional repair technician, expect to pay £80 to £150 including parts and labour. If the control board is faulty, replacement costs can range from £100 to £200 for the part alone, with higher labour costs for installation.
How can I prevent the E13 error from happening again?
Regular maintenance helps prevent heating-related errors. Use a dishwasher descaler or run a cleaning cycle with white vinegar every one to three months if you live in a hard water area, as this prevents limescale buildup on the heating element. Ensure you use the correct amount of detergent and rinse aid, and avoid overloading the dishwasher. Consider installing a water softener if your water is particularly hard. Always ensure proper ventilation around the appliance to prevent overheating of electrical components.
