The E14 error on your Hoover Dishwasher means there is a problem with the water heating system. This typically indicates the water temperature sensor (NTC thermistor) has failed or the heating element is faulty, preventing your dishwasher from heating water properly.
| Error code | E14 |
|---|---|
| Meaning | Water heating system fault - faulty temperature sensor or heating element |
| Severity | Medium — Dishwasher may still run but dishes will not be cleaned properly without hot water |
| Time to fix | 20–60 minutes |
| Tools needed | Multimeter, screwdriver set, towels |
What the E14 error means
The E14 error code indicates a fault in your Hoover dishwasher's water heating circuit. The control board has detected that either the temperature sensor is providing incorrect readings or the heating element is not functioning correctly. The temperature sensor, also called an NTC thermistor, monitors water temperature throughout the wash cycle and sends signals to the control board. When this sensor fails or the heating element stops working, the dishwasher cannot determine if the water has reached the correct temperature for effective cleaning, triggering the E14 error.
Common causes
- Faulty NTC temperature sensor providing incorrect resistance readings to the control board
- Broken or burned out heating element that cannot warm the water
- Loose or corroded electrical connections between the temperature sensor and control board
- Damaged wiring harness affecting the heating circuit
- Limescale buildup on the heating element or temperature sensor affecting performance
- Failed control board unable to properly read sensor signals or control the heating element
How to fix the E14 error
- Switch off power and empty the dishwasher: Turn off the dishwasher at the mains and isolate the power supply. Remove all dishes and racks. Use towels to soak up any standing water in the base. Wait at least 10 minutes before proceeding to allow the appliance to reset and any heated components to cool down.
- Access and inspect the heating element: Remove the lower spray arm and filter assembly to expose the heating element at the base of the tub. Check for visible damage, burn marks, or heavy limescale deposits. Use a multimeter set to ohms to test the heating element resistance. A typical dishwasher heating element should read between 15 and 30 ohms. An infinite reading indicates the element is broken and needs replacement.
- Test the temperature sensor: Locate the NTC temperature sensor, usually mounted near or on the heating element. Disconnect the sensor wiring and test its resistance with a multimeter at room temperature. At 25 degrees Celsius, it should typically read around 50,000 ohms (50k). If the reading is zero, infinite, or significantly different from specifications, the sensor is faulty and must be replaced.
- Check all wiring and connections: Inspect the wiring harness connecting the temperature sensor and heating element to the main control board. Look for loose connections, corrosion, burned wires, or damaged insulation. Clean any corroded connectors with electrical contact cleaner and ensure all connections are tight and secure.
- Replace faulty components: If testing confirms a faulty temperature sensor or heating element, order genuine Hoover replacement parts using your dishwasher's model number. Disconnect the faulty component, remove any mounting screws or clips, and install the new part. Ensure all electrical connections are properly seated and secured before reassembling.
- Reassemble and test: Replace the filter assembly and spray arm. Restore power to the dishwasher and run a short test cycle without dishes. Monitor the cycle to ensure the error does not reappear and that the water heats properly. If the error persists after replacing components, the main control board may be faulty and require professional assessment.
FAQ
Can I still use my Hoover dishwasher with the E14 error?
While the dishwasher may attempt to run with an E14 error, it will not heat water properly, resulting in poor cleaning performance. Cold water alone cannot effectively dissolve detergent or remove grease and food residue. Continued use may also cause additional strain on other components, so it is best to repair the fault before running full cycles.
How much does it cost to fix a Hoover dishwasher E14 error?
If you replace the parts yourself, a replacement NTC temperature sensor typically costs between £10 and £25, while a heating element costs between £20 and £50 depending on your model. Professional repair costs range from £80 to £150 including parts and labour. Always verify part compatibility with your specific Hoover dishwasher model number before ordering.
Why does my Hoover dishwasher show E14 after cleaning the filter?
Cleaning the filter should not directly cause an E14 error, but if water entered electrical connections during cleaning or if components were disturbed, this could trigger the fault. The E14 specifically relates to the heating system rather than water flow. Check that all components were properly reassembled and that no wiring was accidentally disconnected or damaged during maintenance.
