Severity: ModerateWhat Does This Error Mean?
F14 means the water did not reach the required temperature within the set time. The heating element or NTC temperature sensor is most likely at fault.

Common Causes
- Heating element burned out
- NTC temperature sensor failed
- Wiring to heater damaged
- Control board not energising the heater circuit
How to Fix It
-
Reset the machine and run a hot wash programme.
Turn off at the mains for 2 minutes. Restart and select a 65°C programme. Feel the door near the bottom partway through — if it is not warm, the heater is not working.
-
Test the NTC temperature sensor (engineer required).
The NTC resistance should be around 1000–1500 Ohms at room temperature. 0 Ohms or infinity indicates a failed sensor.
-
Test the heating element (engineer required).
A healthy dishwasher heater reads approximately 20–40 Ohms. Open circuit means the element has burned out.
-
Replace the faulty component.
Both the NTC and heating element are replaceable parts. The element is the more expensive repair.
Frequently Asked Questions
Will dishes still get clean without heat?
Somewhat — modern detergents work at low temperatures. But bacteria will not be killed, glasses will not sparkle, and plastics may remain greasy. Do not rely on a cold wash for baby items, cutting boards, or anything that needs sanitising.
