Servis dishwasher M4605AL no go

servis mod M4605AL
There are five prog leds going left to right, then a prog button then a start button.
The furthest right prog led (no 5) is on and pressing prog button does not change it.
Start button flashes, then when pressed goes continuous. Water comes in for about 2 secs only then stops and regeneration valve starts buzzing. Continues buzzing and nothing else happens.
Pressing start button again > pause, press again > repeat of 2 sec fill etc.
Can fill machine with water like this but still regen valve buzzes.

Circuit board shows no signs of damage.
Pump not blocked and working ok on flying lead.
Any ideas please. Not keen on forking out for circuit board which may not be what’s needed.
Mike.

This machine displays faults by all leds 1-5 being on. one of which will be flashing. The flashing led indicates a fault.

Just for your information.

To reset the programme hold down the start button for 3 seconds, the programme led will flash, keep holding start button until programme led goes off.

From what you are saying it sounds light the programme is just starting. have you left the cycle long enough to see if a fault code emerges?

hope this helps.

Doh! If only I’d known that before.
Went back yesterday. Did the above. Everything kicked back into life.
Customer did not have instruction manual. I’m wondering if that would have been in there.
Many thanks Tim.
Mike.
