Our 15 year old Bosch dishwasher has stopped filling although the heater still comes on. I've checked the water inlet valve for blockages and put a meter across it which has given a reading within expected range.
Haynes Dishwasher manual suggests a pressure system fault is most likely but it's pretty vague about how to diagnose/solve the problem
--- "The pressure system has no standard design or location" --- so I'm struggling to know what I should investigate next.
I can't see an obvious, separate pressure switch but there is a large plastic matrix behind the side panel.

pointers as to likely problem / location / solution would be much appreciated.
