Zanussi w/d ZWD1627ow not starting wash cycle

Prod no. 914604003

Hi, this machine starts no problem on a drying cycle. Motor turns and heats up…all good.

But when you select any wash, door locks, pump comes on and then start light flashes constant along with the length of time above and door opens. I tested all 3 valves and got 3.6ohms on the outer 2 solenoids and 6ohms on the centre valve which for the dryer. Tested heater and thermistor and ok. Motor is ok anyway. No fault code comes up??? I’ve never had to change a pcb on a zanussi before so if this is a pcb issue, are there any things like programming that needs to be done?
