Beko DIN28R20 Dishwasher Diagnostics

Hi, could somebody please advise how to run the diagnostics on a Beko DIN28R20 integrated dishwasher? Other guides online don’t seem to quite match up to this model.

I can get onto the diagnostic menu by pressing the power and programme buttons. There are then six options that cycle through by pressing the programme button, but I’m not sure what they mean (doesn’t help that there are a few dead segments in the display too!).

The issue I have is that the dishwasher occasionally stops during the cycle. It’ll then continue the cycle once the door is opened and reclosed. Sometimes it’ll stop once and then run to the end of the cycle once restarted, other times it’ll stop every few minutes. It doesn’t seem to have any issue heating or draining the water, and dishes eventually come out clean.

Thanks in advance.
