aqualtis- flashing lights and f10

hello
this customers machine will work perfectly for a few days then through up an f10 fault. ive done all the usual pressureswitch checks and of course the fault doesnt show when im there.

the latest feedback is that it still shows f10 but now all lights are flashing and drain pump runs continuously.

do the aqualtis boards suffer from the same capacitor fault (flashing lights) and could low heater insulation be a likely culprit. (i havent been back yet).
