While examining dishes on the bottom rack I have come to realize that the cups and bowls are not getting washed properly. Through further investigation I noticed the bottom arm is not spinning. I removed and inspected the arm, noting no obstructions. Is there a way check for proper operation?
Answer Hello Ken,
This is usually caused by a lack of water pressure to the spray arms, This means there is either a pressure loss or a clogged screen inside the unit somewhere. You should check for separating spray arms, missing grommets in the main manifold, and if nothing is found it is time to disassemble the pump assembly from the inside of the tub. You will be looking for any screens stopped up to include the one by the chopper blade, (which would indicate damage to the shaft the blade is driven by). Also, if the discharge housing assembly 6-918807 plate has separated from the assembly, it will have to be replaced since this directs the water flow from the impeller and has a major impact on water pressure produced.
The spray arm is wobbly and hits the bottom of the basket. It was suggested that the arm should be replaced because it is worn. It looks like there should be a washer in the housing of the arm. Thanks
Answer Hello Rudi,
There is no washer under the spray arm. It is designed to be wobbly and the water pressure should take up the slack. If it is hitting the bottom of the rack, there are probably some holes stopped up and the pressure in the spray arm is uneven. I would simply replace the spray arm 6-917642 and the retention nut 99002654. Also check the chopper blade screen. The discharge housing has a flat plate inside it that should be attached to it. If it is loose, this will drop the water pressure.
