This one slipped throught the net, usually send customers to Miele.
Dishwaser fills (slowly as low water pressure), circ. pump starts to wash for about a minute, stops for short while and re-starts. Does this for about 5-10 minutes then stops dead with the fill/empty light flashing. No leaks and all components seem to test ok from connections on module.
Anyone shed any light onto this?
Likely not enough water to get the high pressure switch to recognise it, if you allow it to start, open the door & throw in a pint or so of water just to see will the extra water be enough to make the presure switch. If this works you will have to look at inlet filters etc . When circulation pump starts it should put up enough pressure to make the high level pressure switch come on & stay on, this can be either due to not filling with enough water in time or thet impellor of circulation pump is fouled by blockage of some kind.
