Re: Bosch dishwasher inadequate heating (SRS46A02GB/08)

Thanks for those hints.

However, after spending more time watching it and taking its temperature etc., it turned out not to be a heating problem at all, but a filling problem. It would fill for the pre-rinse, usually fill for the main wash, but then not fill for the rinse.

I’ve just taken the left side off and cleaned out the gunk from the float chamber etc. I also noticed, twiddling the overflow detector, that the overflow float seems to be a tiny bit too sensitive – if I nudged it up to to operate the microswitch, it didn’t invariably fall back enough to release it. So I wonder if a mix of vibration and thermal expansion has maybe been randomly flipping the overflow switch. I tied a small nut on to it to change the balance a little (but small enough that water should still operate it!).

Previously, when I’ve run the self-test, it has always started with showing 2 or 1, and then gone to 0 and stayed there. After putting it back together, the self-test ran showing 0 at all times.

We shall see whether a wash works properly tonight.
