Bosch Dishwasher SGS46E22GB won't stop running

[sanbass]

I was having problems with my dishwasher continually filling and emptying so I replaced the flowmeter and now it works. When I did the first wash on auto it seemed to go fine with correct refill/drain cycles. It also heats up OK (judging from touching the top and sides). However, when it gets to 1 minute before the end it carries on running and won't stop. I don't think it's the pump because there's no water being drained out and when i switched it off there was water at the bottom. I searched the internet and someone suggested the main circuit board may be at fault and so have started removing it and was going to look for some burnt out solder joints. Then thought i might be getting into deep water and decided to write about the problem here! If someone could help I'd be really glad!
Model: Bosch SGS46E22GB
