    OK the dishwasher has refused to run. The left hand light is on, not flashing. There is standing water in the compartment. bIf I turn it to Reset, there are four bleeps. Any ideas?

    If it helps any, the pump seems to run, because I can hear water goung down the drain, although it sounds a bit of a trickle. The (I presume) fill stage comes then (a hissing sound, sort of), but then there’s a slight clunk and it stops, and there’s nothing but a slight hum, and the LH of the 4 LEDs on. This was using the second setting on the dial, our usual cycle.

    If I reset and Turn it all the way round to the fourt setting, which I think is just rinse or 25 minute wash (not sure cos all the symbols have worn off), it does the above, but the third LED stays lit, not the left hand one.

    Oh and it had a load of coffee grounds in it.

    All error codes are given by flashing a combination of the four leds. At best even those are only a guide on what is to be truthful one of the less reliable machines on the market. 😥

    Without any error codes showing then any observations on our part, not being able to actually see the machine will be speculation at best.

    What you describe sounds like a faulty main circulation pump/motor but that should generate flashing from leds 1 + 3.

    A physical and electrical test of all components with the mains plug removed starting with the main motor is all I can suggest.

    Cheers. Well I took the bottom plate off and disconnected the hoses, poked and peered into the pump impeller housing for the drain pump. Found a plastic label stuck across the drain slots in the bottom of the drain sump, that was all.

    The pumps turn OK (by hand) and there’s no burnt electrical smell. I have no idea how to test them electrically (although I have a multimeter) so I guess I’ll just reconnect everything and try it. 😕

    Anything I should look for while I have the base off?

    Update: It drains OK at the start, but there’s a funny rumble first. But anyway, it drains OK (I checked) then fills, then cuts out once it’s partly full. No flashing lights, just a sudden stop before the water has even covered the elements. No noise but a slight hum. If I reset it, it will go through the same stages but stops at the same point.

    How odd. I thought I’d leave it in the ‘slight hum’ phase. It hummed for a few minutes then the detergent door flipped open, which would normally release the tablet. Nothing else happened – it just carried on humming. The elements are cold.

    Oops, spoke to soon, no, they are now red hot. Switched it off and doused them with water. 😯

    Still sounds like the main circulation pump is goosed.

    If you remove the mains plug, lie the machine on its left and side (from front) and remove the base you can stick a small thin screwdriver into the rear of the main circulation pump motor ( not the small drain pump ) to see if the vanes of the cooling fan will turn freely, if this fan/rotor is very stiff or seized then TBH its time to invest in a new dishwasher.

    OK I’ll give it a go later.
