The F01 fault code signals “motor triac short”, which, in most cases, requires professional help.

An electronic component featured in the printed circuit board (PCB) is the triac. If it is shorted, it needs to be replaced. This type of failure often occurs due to outside factors (malfunctions in other components, short circuits due to poor insulation, etc.)  Not unlikely, the problem will necessitate replacement of the entire module. This is a kind of task, which a trained technician only can handle.
