Hotpoint WT741 Stuck on 01 minute
I have just changed the PCB on this machine now it fails to rinse and spin after a wash; instead it agitates endlessly on 01 minute until customer cancels.
Sent the PCB back to EMW who tested it and found no fault with it.
Have tested heater and motor for insulation both have infinite, I even changed the heater anyway still the same, is there any think else that I can try.

Thanks for looking

On A1engineers suggestion
I removed the sump hose and pressure chamber along with its hose and cleaned both although they were not that dirty refitted put it on a 30 minute wash and sat and waited all worked ok. I let the customer try it for 2/3 weeks and so far it has worked ok.
