Maytag 7600 dishwasher. The wash arm seems to have plenty of water and no blocking by debris. However, it wobbles and therefore gets stuck (by water feed tube on bottom) and stops turning. The screw is part of the arm assembly......should I buy a new arm?
Answer Linda, The first check needs to be at the water manifold 99002642 make sure the manifold is still attached to the tub brackets and the outlet at the top of the pump W10296525. Then remove the lower spray arm, and check the bottom side center for excess wear and damage to the openings. The last check is to the motor, remove the lower access panel, and make sure there is at least 1/4 inch clearance between the bottom of the motor and the floor, if the dishwasher is setting on the motor, this can also throw everything out of alignment.
Lower washer arm will not turn during wash cycle. Stays stationary. Should I repair or buy new?
We would need to have to model number to help to determine what my be going on with the unit. It may be a bad impeller or just something that is lodged in the pump assembly causing to not work properly.
How can we tell if the wash arms are worn?
Answer Hello Gloria,
The spray arms don't "wear" in that sense. The thing you are looking for is any holes clogged with debris and separations between the two halves of the spray arms where they are "melted" or crimped together at the factory. When the spray arms separate, the water pressure escapes from the separation and causes a "wave" to develop in the water in the bottom of the tub and this causes the water to jump the air gap. This in turn puts water in the floor.
i am getting noise during operation so i checked it out while not running, it appears that the lower washer arm is rubbing against the lower portion of the manifold. is there a gasket or friction washer that goes on the lower washer arm to act as a bearing and raise the washer arm so that it does not hit the manifold??
Answer Bill, No there are no bushings or seals between the lower wash arm and top of the pressure dome in the center of the pump. You mat want to check and make sure the bottom of the spray arm is not worn out, and that the shaft it mounts to is straight and has not been dislodged, by something sticking out the bottom of the lower rack. You may need to remove the lower access panel and check that the motor is not sitting on the floor, there should be at least 1/4 inch clearance between the bottom of the motor and the floor. Thanks and Good Luck
