Hi,
I am looking at a Rangemaster RDW6012FI Dishwasher. The top spray arm is turning ok, but the bottom one isn’t turning at all. The arm itself is completely unblocked. Any clues appreciated. I can see that the main wash pump assembly has a water valve on the side, does this control flow to the lower arm? if so is this the most likely culprit or is it more likely to be the PCB? Can you get just this valve or is it only available with a replacement wash pump?
Thanks,
Jon
