Water not coming in. Been seen twice by British Gas engineer (British Gas Homecare appliance cover) and have been told its not fixable, not safe and must be replaced. I would rather repair it.

Hello,
This is difficult to diagnose especially as it has been condemmed by your Insurance cover.The normal cause for these dishwashers to not let in water is an airlock.Now if you know a bit about DIY you could have a go.Firstly remove the kicking board from the bottom of kitchen unit then remove the metal plate across the bottom of dishwasher in between legs.You will have to prise this off with a screw driver it does not have to have the screws refitted it can just be pushed back into its groove.Make sure the unit is switched off.Inside the unit towards the left hand side is a press. switch with a small clear nylon pipe on it and a couple of wires,its round about 2" Diameter.you can pull the whole thing forward to you it is sort of clipped on to body of unit.When you can get at it undo small wire clip off pipe then prise pipe off switch hopefully this will expel any air trapped.Refit pipe and switch and try again if that does not cure it then you have to pull out the dishwasher to get to the water inlet at the rear of the unit.undo the water pipe (water off first).Remove the screws from the plastic panel around the valve and the screws holding the valve in,pull plastic plate out of way and alongside the valve you will find a pink nylon tube with a white plastic bung in the end gently pull out bung and you should get water out of pipe onto towel.When empty put in bung and refit all now reconnect water and try.If that does not cure it then you do have a more serious problem.

Hope I have Helped.

Good Luck.
