WF80F5E0W4W machine stops at different stages of wash, occasionally it will do full wash, other time it took almost 2 days!!! Any idea of the problem, could it be the PCB?

These days it's rare for a washing machine fault not to trigger an error code and abort. There are anomalies, one of which with some washing machines if the heating element goes open circuit it can cause a washing machine to stick without causing an error. The nature if this fault is that it could be so many different things you would need an engineer to diagnose it.
