I have an inbuilt whirlpool dishwasher it is marked with an Ikea logo not sure of the model its D something.
Anyway it fills with water and just sits without the main washer pump starting, the water heats up if left it would stay like that all day, if you open the door the program can be cancelled and as the door is closed again the drain pump takes all the water out of the machine. Anything obvoius, or is a new washer on the cards?
