My dishwasher has developed an odd fault. Most washes it refuses to wash anything properly in the back of the lower basket on the right. Everything else washes fine. Testing shows the lower arm is spinning ok and if I am quick enough I can open the door and see water coming out of all the holes in the lower arm. This morning I put a dirty cereal dish there and started a cold rinse cycle. Stopped it after a few seconds and dish was still full of dirt. Moved it to the left back of the lower basket and repeated, and within seconds the dish was pretty clean. I am stumped as to what may be the issue and wondered if anyone here may be able to help.
