Hi there, AEG LW1460.

This washer has only a cold water inlet, and an internal water heater. However, the heating function no longer works. Otherwise all cycles complete normally.

- I opened the washer and tested the 230V 1950W element with an ohmmeter: 25Ω or so.
- The 4.8 kΩ NTC thermistor was an open circuit (infinite resistance).

I ordered the thermistor and installed it today. the new thermistor reads about 8.5 kΩ at a water temperature around 15ºC.

However, the washer is still not heating. The element continues to check out at 25 ohms or so.

One funny thing is that measuring AC voltage between either terminal of the heater element and ground gives me 120V, but voltage between the two element terminals is 0. I find that strange because this is a 230 V unit and the heater is stamped as 230 V as well.

Options:
1. Replace the element (includes another new thermistor) for around $200 CAD.
2. Call in the tech to diagnose properly for around $200 CAD + parts.
3. Any other ideas?

Would be very happy to have your views or any other options.
