I have a Hotpoint LTB 4B019 dishwasher. Recently we have been turning it on, shutting the door and after a few minutes of inactivity, we open the door to find the power light flashing and the first and third light on. Any ideas what this fault is?
I believe error codes can change; the nearest model I can find states the first and third lights flashing indicate a pressure switch error E7, which includes checking the circulation pump.
