Lower dishwasher arm not rotating - GE Dishwashers

Confirm that lower washarm is rotating. Initially check by rotating by hand. Second mark arm position turn on unit stop and heck arm position.

Listen very carefully and confirm arm is turning. It is often found debris clogs the lower arm jet preventing the arm from turning.

Also check the water level in washer sump. Low will also keep the arm from rotating.

Hope this helps.

If is clean dishes in the upper basket, I conclude that the pump produces enough pressure what means that the lower spray arm for some reason does not rotate and because that washing result is bad. Before washing I would check the lower spray arm rotates freely and after that open the door during washing and check if the lower spray arm rotates. Sometimes, the holes in the spray arm clog and disable turning which leads to poor washing results in the lower basket.

Both upper and lower washing arms operate on the water pressure and angle of water flowing thru them.
Pressure provided by water pump.

Just about anything that contacts the rotating arm can stop it.
Best thing to do is re-arrange items in dishwasher so that arms can spin freely.
One can always spin washing arms by hand to ensure proper clearance.

Hope this helps...

Hi Matt.
The lower housing underneath the lower wash arm may still have something blocking the water passages.

If the spray arm is clean and it freely rotates try lightly pressing down on the wash arm and then rotate it. Your checking to see that when water is applied to the spray arm it forces the arm down against the lower housing tower and hopefully does not lock up. If it does lock up while pressing down and rotating obviously you need to find out what the cause is.

You may have to remove the lower wash arm housing and clear the debris from the water passages. Once the passages are clear it should work fine.

Thanks for using FixYa,

good day,
hope this link below will solve your problem.

On the LG LDF xxxx dishwasher family, the Vario feature uses a motor/check valve to switch between "full power" cleaning from _either_ the lower or the upper spray arms, never at the same time. So, not seeing the upper arm spin during the lower arm spinning is standard operating procedure.

But back to your problem. Step one would be to remove the filter assembly again and make certain that there is nothing (debris, broken glass) blocking the white areas where the check valve rotates to switch between upper/lower spray arms. A blockage there ~could~ cause impotent spraying/cleaning.

If there is no blockage and the impeller remains in good shape, suspect a failing wash pump motor. Try to isolate the noise to that motor.

Watch for error codes on the display and report back what you find, OK?

Good Luck!

Yes there is the Water Div valve, it diverts the water between the wash arms.

Yes!

rotation is only by water coming out of angled jets at end of spray arm. probable that these are blocked. take spray arms out and run water thro centre hole and remove whatever is blocking the jets - usually rice or sweet corn

Maytag MDB4000AWW dishwasher:

Neither bottom or top arms seem to be rotating during wash cycle and dishs do not come out clean!
