Tools needed:
- Multimeter
- 13mm socket
- 7mm socket (optional)
Before doing this you will need to remove the left side panel.
1. Verify that the connections shown below are securely attached and in good shape.
2. Verify that the machine's steam boiler safety thermostat is not tripped by depressing the central button with your finger. A protruding central button that clicks down softly when pressed indicates a tripped switch.
3. Pull the black rubber protective covering back from the heating element legs.
4. Set your multimeter to the lowest resistance range and probe the element legs. (You may need to unscrew the electrical connections to get an accurate reading.)
5. You should see a resistance reading close to 12Ω (+/- 10%). If you see a resistance value much higher than 12Ω or the "O.L" message indicating discontinuity, that's a sure sign that the heating element is compromised and will need to be replaced.
