Thanks for all your help.

I’ll order a replacement capacitor to see if that works and let you know in a couple of days.
Worst case I’ve learnt a lot about how dishwashers actually work.

I’ve just tried it again. The sound is coming from the motor. It makes a constant buzzing/droning noise (like it is spinning) then after about 20 seconds you can see the water in the pipe to the upper spray arm start to splash around.

Is that capacitor in the link the compatible one for my dishwasher? The current one is ICAR MLR25L40303063.
Is it worth trying a replacement capacitor?

It fills. Towards the end of filling I can hear a motor (or possibly the heating element) kick in. Once it finishes filling, there’s a slight pause and the pump tries to pump the water to the spray arms. After that it drains and the process repeats. It is still following the full programme but, presumably, not enough water inside it.

I have noticed this morning that the second chamber of the blue water in box has drained and is currently empty. It has been sat for just under 2 hours since the last test.

I managed to remove the switch and the hoses last night. Both hoses seemed dry and clean on the inside but 1 of them has what appears to be a scorch mark on the outside. I’m not sure if the material in the hose has reacted with contact to the black material on the underside of the main dishwasher body. Or if it is near the heating element and has actually started to burn after 16 years. Either way, I replaced that hose with one I had lying around then tested both switches. I can hear each of them click as I increase the preasure in their respective chambers. I’ve reattached the switches to the dishwasher and run through a cycle but the water level didn’t improve and the inside still appears dry.

I poured the water in midway through filling and it cancelled the programme and drained the water.
I then waited for it to finish filling and start trying to clean before adding more water and it accepted a little extra water. But when I put enough in it that it would be about an inch below the spray arm, it drained the extra water and carried on with the same volume of water that was originally in it (just from the fill process).

The fill process takes about a minute.

I’ve let it fill and opened the door. The water barely comes above the filter so probably 2 inches below the lower spray arm. I’ve added a photo of it to the link in my original post but you cannot really see the water as it is so low.
