Sorry guys, I can't give you any details re this machine.
I live in New Zealand but don't use F&P because of all the electronics packed in and very expensive service or back up.
Washing Machine i use is Simpson, (Australian made) with a simple electromechanical timer and rotary knob. Very reliable > 10 years old now.
Dishwasher i use is Westinghouse (Australian ) with electronic timer
and already problems after three years. The programme only starts via the timer delay e.g. after 1 or 2 hours after starting the d.w. cycle.
I reckon that the electronic parts simply don't last in the arduous environment with humid temperatures and steam and soap fumes I guess.
Back in The Netherlands, my parents had an AEG Lavamat washing machine which lasted for 16 years when the actual washing drum bearings worn out, mechanical clockwork timer of course. Also they had a Miele dishwasher which lasted about the same time with no control problems, only a water pump was replaced once, with lose plastic impellor over the 16 year period.
IMHO, Electric controls are poorly designed and, or made to fail just after the warranty period expires. If not that than it is plastic, which has it's usuall fatigue problems too.
On your photo I think that it is a mosfet, thick track at terminal 3 and heatsinked through cct board via terminal 2 and rear of case.
