The top spray arm was not rotating on this machine so I replaced the ditributor and heater unit, just had a recall two days later now the bottom spray arm is not rotating!.
Checked and no water is spraying throught the bottom spray jet. Could this be a faulty distributor or is there something else I should be looking at?
Did you check the IC on the control module ? Sometimes if the diverter valve goes , it takes out the chip on the main board .You can see the top of the IC broken off if this is the case .
I’d also look to make sure the new heater was seurely fitted and not leaking onto the diverter motor from one of the seals .
