What the E03 Error Code Means

The E03 error code on current Lamona integrated washing machines indicates either that the heater has been continuously active when it should not be, or that there is a short circuit fault on the fill valve triac. Both causes point to a technical fault within the heating or water inlet circuit. E03 is not something that can typically be resolved by user checks alone.

Note: on some older Lamona washing machine models, E3 indicates a drainage fault — the machine is not draining water correctly. If your machine shows E3 and is not draining, check the pump filter and drain hose first. On freestanding models such as the FLM8700 series, E03 indicates a pump fault or blocked pump filter. Always check your user manual for model-specific information.

Safe Checks You Can Try

Reset the machine
Turn the programme selection dial to off. Unplug the machine from the mains socket and wait at least one minute. Plug back in, turn on and restart a programme. If the error clears and the machine runs normally, the fault may have been a temporary glitch.

If your model shows E3 as a drainage fault — clean the pump filter
The pump filter is located behind a small cover panel at the bottom front of the machine. Place a shallow dish or towels beneath it before opening as water will drain out. Twist the filter cap anticlockwise to remove it, clear any debris, and refit by twisting clockwise.
