The upper arm on our 11 year old Frigidaire dishwasher won’t spin. The arm can be spun manually and the holes appear to be clear. I ran it with the door open and it looks like a lot of water is flowing thru it. All I can think of is that either the tube going up to the arm is restricted or the pump is going bad. I hate guessing when the pump motor is $150.00.
Any ideas?
Thanks
