Goatboy, don’t worry, I am an electrician. I fiitted an external hose to the drain and took the water outside. Thats why I don’t know what caused the problem. The dishwasher was plugged into a RCD the whole time, no water entered the base whislt the machine was on.

Just to report back, I kept the pump off, ran water through the machine on a cycle, collecting the waste water as I went on and it all started sounding better. I put it all back together and it seems to be working fine.
Thanks again to all those who helped and yes goatboy it was worth looking at again.

Thanks for all your help guys, I managed to split the drain pump but found no blockage, the impeller seems to be sprung is this correct you can turn it and then it springs then turn again etc. Have tried it again and it sounds like the pump is trying and going through various settings i.e. I can hear what sound like relays clicking in and the pump makes various noises.
Not used to not being able to mend things, but it’s looking like a new dishwasher.
Any recommendations, it has to be a slimline. Looked on Which? and they still recommend Bosch but after the palava I have had with this one I am not sure.

As a fellow yorkshireman, do you offer a service of repairing dishwashers?
Think I might have got as far as I can go even with your excellent advice, can’t split the drain pump so it’s either get someone in or but another.

Is this said drainage pump, if so how does it twist apart and where would i look for a blockage, would it be in the flexible black rubber section where it joins what i imagine would be a sump.

Just behind the two rear pipes that are adjacent to the blue one I seem to have what looks like a plastic container that seems to be full of some sort of orangy brown goo, is this worth investigating?

No worries smartin thanks for trying
Is the matrix just the one large piece of large of plastic that the two rear tube and the blue pipe enter into. So if I remove the two rear tube and undo the circlip on the blue pipe I should be able to get to the pump and ultimatley the impeller. The rest of the mechanism looks like it was built by the people who invented the game “mousetrap” so I don’t want to disturb it too much if necessary.

Is that grey plastic assembly around the filter? Can’t see any interlocks or any other type of switches on that.
The pump is running, as I switch on it starts and then changes frequency after a couple of seconds as if it is attempting to turn. I am an electrician and am used to working with electric motors. How can i actually get to the impeller to attempt to turn it as I think that may well be the problem. As penguin mention it could well be a piece of glass or something similar.

Wow, thanks for the quick reply.
I have taken off the metal plate and can pull a tube away from the drain mechanism. How would i find any potential blockage
