Howdy... I recently replaced the rotted rubber sump on this 2004 ge dishwasher, all was great for a month or so, then the lower spray arm stopped working. Top cleans just fine, fills and empties fine, just the lower arm doesn't spin. So I took the nut and fine filter off and looked down into the top of the motor, and there is/was a hard plastic ball sitting in the bottom, effectively blocking the water flow, I believe.

Where did this come from? It looks like the ball from a check valve but the parts breakdown doesn't show it individually.... did it bust out from its home somewhere inside the motor and just come to rest here? Can I put it back in with maybe a new spring lock or something? Or am I looking at a new motor?

TIA for any help....

exploded view


I took everything from 502 and above off, looked down into 455, and the ball was sitting there. This I believe has restricted the water flow, keeping the lower arm from getting enough pressure to spin.

Take a look at this video. At about 2:50, does that look like yours?

thanks for the link.... looks very similar.... chamber ball? never heard of it, and never saw one during the sump replacement... I don't see it listed in the parts diagram above... but yes, very similar.. but, everything I've found since seeing the video says "orange ball" mine's white... don't know if it could be different, but, found this researching....: "The white ball is suppose to be in the float that's whats stops the water when it's at it's fill line ".... checking my float now.

Maybe.. but I only found one so far....

Dishwasher Pump
The two small white balls that you found in the bottom of the dishwasher, called check balls, are part of the dishwasher pump assembly, which is responsible for moving water out of the unit. Before you can return or replace the balls, you must access the pump. Disconnect power to the dishwasher and then open the dishwasher door, slide out the bottom rack, and turn the spray arm and the spray arm support in a counterclockwise motion to remove the spray arm housing. The pump is inside the housing for the spray arm.

Disassembling the Pump
Once you have reached the pump, the pump must be taken apart to reach the part where the check balls are usually situated. Remove the eight screws holding the pump cover to the outlet, then lift off and remove the seal from around the pump. Under the seal is a screw assembly that can be removed with an adjustable wrench and then the wash impeller, which is a small round disc, can be lifted out. After removing the impeller, take out the three screws that hold the separator in place, which is the larger round disc around the separator screw assembly. Take out the separator and then remove the screw holding the inlet base into the separator. A perforated plate is under the inlet base with a small hole on the lower right side where the drain check balls should be.

Check Balls
Replace the white balls into the small opening on the separator assembly base and then ensure a gasket is underneath the inlet base that sits on top of the drain check balls. If the gasket is broken or missing, that might be why the drain check balls fell out in the first place. Contact your dishwasher manufacturer or another qualified service professional for assistance. If the gasket is in place and the perforated plate that holds the drain check balls does not seem to be damaged or broken, move in reverse order to reassemble the impeller and the spray arm housing.

Drain Check
After you replace the balls and reassemble the dishwasher, run a normal wash cycle and monitor the dishwasher to ensure that the unit drains properly. If the dishwasher doesn't drain correctly, the drain check valve might need to be inspected or repaired. Open the bottom front panel and set an empty container down, and then remove the drain hose and set the end of the hose into the container. Remove the other end of the drain hose from the connection point on the garbage disposal or air gap and blow some compressed air through the drain hose. This will help remove any obstructions. While the hose is disconnected, reach into the dishwasher housing and unscrew the check valve, which is normally connected to the drain hose. Ensure that the flapper on the valve can open and close. If the flapper does not operate, the valve will need to be replaced. Look inside where the valve is connected as well to see whether any debris is causing a blockage. Clean if needed, then replace the valve and the drain hose. Contact an expert if the problem continues.
