Swan SDWB75110 Dishwasher

Hi and Happy New Year,
Our dishwasher stopped turning on after a wash. On checking everything unplugged it for a few days. After which I decided to just take a chance and see if it started to work. Which it did.
This as now happened a few times, on which after unplugging for any number of days, which is completely random it decides to work.
Checked the controller which appears to have a live voltage going to it. Checked pipes and cleaned the full unit including draining without tilting the unit.
The unit as now decided to not turn on after around 3-4 days, which in the past worked on occasions.
Does anybody have any idea what if anything could be causing this issue. I was going to strip the full unit down, but wanted to get any advise before doing this.

When in fault mode, no lights show, no response from any button presses, including holding down each to try a form of reset.
But voltage again reaching control panel.

Any help would be very much appreciated.

Thank you.
