Re: Upper arm does not spin

No I don't believe its the pump. I believe the lower spray arm is possibly split open on the side causing a loss of presure and flow to the upper arm and overloading the door seal. As well the loss of flow to the upper arm will resulted in it turning too slow.

Apparently no water pressure to upper washing arm.

Hi sounds like there is a blockage in the circulation pump which causes low water pressure as it cannot push the water around. You would have to remove the unit and turn on it's side and remove the circulation pump to clear the blockage.

Also check all the holes in your spray arms for any blockages. Best to remove each arm and clean in the sink. Any blockages causes the arms not to turn.

Top rack does not wash dishes.

Possible causes of spray arm inefficiency:
Loading large or tall items in the lower basket which stops the arm revolving.
Upper spray arm split along seam.
Upper spray arm blocked.
Under dosing of powder causing foam and reducing upper spray arm water pressure.
Blocked strainers reducing water to circulating pump, therefore reducing upper spray arm water pressure.
inefficient wash motor impellor (faulty)

Upper spray arm on dishwasher does not move

you most likely have gunk inside the arm or holes not allowing the water to spray out and turn the arm. Otherwise, the arm bearing may be stuck and will need a gentle push to loosen up.

Spray Arm Doesn't Move on my GSD5630d01ww!

When you say the dishwasher is running do you mean that the pump is operating?  If the pump is not pumping water the arm will not spin.  Is there a bottom arm and is it spinning?  If it spins then the pump is working. The upper arm will not spin if it is blocked by hitting a large dish or utensil.  There should be some sort of tube or tower (some are collapsible) in the center of the lower rack that shoots water into the bottom of the spin arm above.   Is it missing, blocked or clogged?

LG LDS5811WW Low pressure out of spray arms

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!

Lower and upper spray arm will not turn

If the spray arm is not binding due to worn out plastic bushings, then it could be a lack of water pressure, because it is water pressure which makes the arm turn.
Give it a gentle tap in a clockwise direction,,does it spin easily?
If it does,,then it will be lack of water pressure that will be the cause.
Possible pump wear or failure.

Spray arm does not move

the spray arm is moved by water spraying out of angled jets at the end of the arm. the mostly cause of no rotation is these jets being blocked - its not always obvious. remove spray arm and run water into centre hole and see if you can see anything blocking the jets
