My dishwasher diplomat adp8242 is showing the E3 error light (the first 2 lights on the left flashing and the 5th light on permanent). In the book it says that it means the water isn't heating up, can you help me as to what I need to replace/do to get it working again.
Many thanks.

Hi Dean it could be that the heater stat has tripped, look underneath and there is a white sta with a red button.Pressthe button and see if it clicks,with the power off.If it doesn't then you will have to change the heater element.this can be done from the front.All the best.
