Bosch Dishwasher SGS5012EP/04 tripping mains at specific point in wash cycle

My Bosch dishwasher has started tripping my mains earth leakage at the specific point indicated in the picture below, 90% of the time. Never anywhere else. What is interesting is that it's pretty much exactly at the same interval as the different settings, just after the last one (glassware). My gut feel is that it is the control unit, but Bosch have informed me that the part (171377) has been discontinued as the dishwasher is a 2002 model. I could try and find an old second hand part, but unless I'm sure this is the problem, it could be a lot of effort for nothing.

I would super appreciate it if someone "in the know" could confirm if I'm possibly correct or what else I could look at. The dishwasher itself is still in good condition, so my feeling is "why replace if I can repair".

Many thanks

Hi, as much as we would love to help you, we can't, your model is completely different than the USA models.
