Question about Danby 22 in. DDW399 Free-standing Dishwasher
My Danby dishwasher (DW) stopped working. The spray arm
stopped spinning completely and very little water was coming out of the arm.
When I removed the spray arm (CAUTION: reverse threaded, turn CW to loosen and CCW
to tighten) and ran the DW, very little water was spraying out of the pump.
I thought maybe the pump was clogged. So, I followed the recommendations I had seen online about running a few cycles with Vinegar to clear the crud from the pump, but this did not help.
It seemed like the motor was operating, and there were no strange smells to indicate the motor was burned…just no water spraying. So I thought it must be the pump. Before disassembly, I tried to locate a replacement pump. I searched far and wide, both locally and online, and could not locate a replacement pump. So with nothing to lose, I decided to disassemble the DW, take a look and see what I could find. I am glad that I did.
The bottom line is that I disassembled the dishwasher and found that the plastic pump impeller had worked its way off the pump shaft and was not turning. I forced some Teflon plumbers tape over the shaft and forced the impeller back onto the shaft. The impeller has a flat spot to line up with the shaft and I pushed the impeller down on the shaft as far as it would go. I then used a small socket to fit over the shaft and GENTLY tapped the impeller for a final seating. I reassembled the dishwasher and it worked like a charm.
Since I could not find any service manual or instructions online for this DW, I thought I would share my disassembly/reassembly procedure.

Check and make sure that there is nothing blocking the pump inlet underneath the mesh removable filter. It should be making a whirring sound like it's trying to pull water in in a cycle. If it's not making that noise your pump is shot.
