The novice

My dishwasher has one spray arm that will not rotate. I have cleaned the filter on the bottom of the basin but am wondering how to remove the spray arm without breaking off the two tabs that hold it down in place? I have tried pulling them back but they are not very flexible and I am afraid I will snap them off.

Stick a screwdriver in there and turn it counterclockwise and the whole assembly will unscrew from the tub.

The arm came right out thank you for the reply. I see no buildup or blockage of any kind. Still get little or no pressure to lift rinser or spin arm. Am I now looking at a weak pump?

Put the sprayarm back in, start the washer, and when it’s done filling tell me how much water is in there, you might not have enough water.

Doesn’t seem to keep any water laying in the bottom. The only water is in the drain basin.

Can you hear it filling with water when you start it?

I don’t hear it filling and it seems like it is pumping it out.

You need to figure out if it is draining while it’s filling or is it just not filling?

If it’s draining when filling, do this. Take off the kickplate at the bottom. To the left of the motor is the drain solenoid, is it melted and stuck in the down position?

It seems to hold maybe a 1/2" of water at most. Water has come in enough to raise the sprayer somewhat. Is the device in the front left corner a float switch? It seems to be draining and filling at the same time.

With a stuck drain solenoid is the pump moving water out the drain and into the spray head at the same time when it should be doing one or the other. Resulting in low pressure on the spray head.

The drain solenoid seems to be functioning at least I can see it cycle with maybe a 3/8" move.

Yes, it’s a float switch in the left corner…A stuck solenoid will cause a drain and wash at the same time. So you can manually move the timer around and see the solenoid engage and disengage, if that is the case, you may have a bad flapper seal in the pump causing it to drain and wash at the same time which would require the pump to be replaced.

A new pump and a new timer in a 9 year old dishwasher is not what you would call a smart investment. Would you agree? I want to thank you for all your help it is deeply appreciated.

Nope, time for a new one
