I have a Bosch SGV43A03GB dishwasher about 6 years old.
Recently it has not been getting things clean like it used to and investigation has showed that the mechanism that switches water to the top and bottom rotors in turn is not working.
Only the bottom rotor sprays any water, although in the past only the top one has worked. It seems to be stuck feeding water to one rotor, although possibly it occasionally does move.
The water alternator is part of the instantaneous water heater assembly. I have checked all the wiring to this and cannot see any problems. There are 3 wires going to what I think switches the water, black/grey, a double white wire, and a red wire. Whilst in operation there is 240V between the centre white wires and one of the other connections (cant remember which one) every few minutes the 240v switches over to the other wire but only for a few seconds. Is this normal ? I also cannot see how on earth you would change this assembly although replacement are readily available. It seems buried deep at the bottom of the machine and very difficult to get to.
I am loathe to scrap this machine as I have in the past stripped all the internal pipework and it is now immaculate inside, when working it does a really good job.
My questions are : does it definitely sound like the water heater or could something else be at fault ?
Does anyone know someone who could be recommended to fix it in the Hatfield, Herts area ?
How much should I expect to pay if it's the water heater that needs replecing, the part is about 80 quid alone.
