Hello, have spent a lovely 3 hours climbing around our dishwasher.

Has started giving an F12 fault which is ‘check incoming water’ apparently, as though it can’t get enough in to start the cycle.

The feed is taken from the kitchen tap which is working just fine, so actual flow in is there. Haven’t changed any plumbing or works recently.

It’s then fitted with an aquastop which connects into the back of the dishwasher with a two prong plug thing electrical connector. I cleaned the filter on this which had a speck of limescale to come out but generally was clean and nothing stopping the flow.

How do I work out whether the dishwasher is at fault or if the aquastop is somehow activated and that’s the reason no water is getting in?

Can’t see any leaks and the under tray and floor are all bone dry, it’s been installed and run without fuss for years now. We did have a water leak in the street/locally with low pressure this week which seems coincidental but maybe something?

Have a multimeter but don’t really know much beyond that when it comes to testing connections and continuity!

Can you test for power on those leads when the machine is on. Does the solenoid in the pipe click when it gets power?

It feels like the AquaStop might just be stopping the Aqua. Can you remove it from the loop and test?

You should find if you have a dig that the hose will have standard ends, if not external then inside the machine, so can be replaced with a basic plain hose if you need to test.

I had an Aquastop hose fail with the solenoid stuck closed and I just deleted it by putting a plain hose on to prove it.
