Possible Causes
Partially failed heating element (dual element with one side open), Heavy scale on element reducing heat transfer, Low mains voltage, Faulty power relay cycling incorrectly
How to Fix / Troubleshooting
Safety: Unplug and allow the machine to cool before testing electrical components.
- Verify mains voltage: Measure line voltage and ensure it matches the machine rating.
- Descale boilers: Perform descaling on brew and steam boilers to remove insulating scale from the elements.
- Test heating element: Some elements have multiple circuits. Measure resistance across each pair of terminals and compare to spec. Replace the element if one circuit is open.
- Check relay operation: Listen for rapid or irregular clicking from the heater relay. Replace the control board if the relay is malfunctioning.
