Possible Causes
Partial failure of heating element, Heavy scale on boiler and element, Low mains voltage, Faulty power relay limiting power
How to Fix / Troubleshooting
Safety first: Unplug and cool before internal checks.
- Compare to spec: Check the expected warm-up time in the Lelit manual. Slight variations are normal; very long times indicate a fault.
- Descale boilers: Perform a thorough descaling to remove insulating scale from the element and boiler walls.
- Measure element resistance: Verify that the heating element resistance matches the rated power. A significantly higher resistance can indicate partial failure.
- Check relays: Inspect heater relays/triacs on the control board for signs of overheating or poor solder joints. Replace the heater relay/triac if defective.
