Re: dishwasher indesit di620
Check the tap is turned on, test the fill valve with a megger or multimeter, check the heating element for insulation faults, check the wiring between the PCB and fill valve for continuity, check the pressure switch for correct operation. If all else fails try the control PCB.
All with the mains plug removed of course.
You could of course just buy something better, it wouldn’t be difficult. :rolls:
PS. Removed your other post, it only leads to confusion. 😉
