Bottom wash arm

The bottom wash arm will not spin when the dishwasher is in use. It doesn't catch on anything and will spin around by hand. There is no blockage and the top arm works fine. It has got me totally baffled.

    Have found the problem now.
    A small grey piece of plastic had broken of the underside of the arm. therefore the water pressure wasn't high enough to turn the arm because it was all coming out of the large hole underneath.

There is a blockage but may not be obvious. arm turns only by water spraying out of the angled jets at the end of the arm. take arm off, run water thro the centre hole and this is udually enough to force the debris to the jets. clean out and check

Could you explain why the bottom arm spray is not spinning but the top one is working fine

Does the arm move freely if you remove the lower basket and spin by hand? If not, remove the arm and make sure there is no food or stringy objects around the lip. If it does then you'll need to check for blockages I the manifold (the pipework that connects the arm to the wash pump

Is water flowing, ie pump activated. if you can remove the arms, check the seals are clean. Check to see if the arm is hitting anything by spinning by hand before cycle. Also remove arm and check to see if nozzles are blocked, sometimes you cant see the blockage as the blockage is further inside the arm. Use tweezers to remove anything. Bottom arm could be inhibited by missing roller on rack also

Neither the upper or lower wash arms spin.

Circulation pump might be faulty. or spray arms are blocked. remove spray arms and clean them and try it again.

Upper arm does not spin

If the sprayer arms continues to get caught, see if your racks can be adjusted in height. Some can be moved up or down by the side brackets. Otherwise freely spin it with the unit off and see if it is just getting caught on a pot/pan in the unit. Otherwise, it may not be getting enough water pressure to turn it completely around.

Top spray arm does not turn during wash or turns is free of clogs and spins freely by hand

It will spin freely by hand, but needs to spray water out of the jets at the trailing edge of the arm. Check inside the arm for blockage and make sure that water is getting to the upper arm from the pump.

The bottom arm on my Diplomat dishwasher does not rotate during the wash cycle. All of the holes in teh arm are clear and the arm on the upper basket works fine.

Does the arm rotate if you turn it by hand? If it does. and the top arm rotation is normal, there must be a blockage further back in the piping. Remove the arm, it us usually held in place by a nut or a clip, and check the hole, even try operate it without the arm so see if it will dislodge anything. Also check the inside of the arm again, there may be something there that you did not see earlier.

Yes, the wash arm should spin freely. Recommend that you remove the arms and search for what is stopping it.
In addition to hard water, the ultra-cheap dishwasher powder really does/can leave calcium-like deposits behind. Use brand name powder for 30 days and you will see a difference. Never use gel or tablets in any dishwasher.
Adding a whole-house water softener would eliminate 90 % of your problem. The other 10% will be taken care of by not buying ultra generic powder.

Washer arm not working

If your dishes are getting clean, then your problem is a "feture" not a failure. The LG LDS5811 has a Verio motor/check valve that switches between cleaning the upper dishes and then the lower. Depending on when you open the door, one arm will not be spinning.
All the presure is routed either to the lower or upper arm, so it really does help - especially with a water conserving model like the 5811.
Good Luck!

I have a Frigidaire Ultra Quiet Plus dishwasher. The top spray arm isn't spinning during wash. The bottom spins fine and I can spin the top freely by hand. It appears there is not enough water pressure...

I may have the answer. I had what sounded to be the same problem. I found the dishes were dirty after they were cleaned, but I found there may have been a big pot lid blocking the upper arm. I decided to run the machine again, and after a bit opened the dishwasher after to make sure it was not a problem with the arm. Sure enough, the arm wasn't moving. However, I found out on the Frigidaire webpage that some models have an alternating spray cycle, where only one arm spins at any given time. After reading this I checked again, and it had moved by that time. I checked a few times more to confirm this. So it ended up it was an arm blockage after all. Hope this helped...good luck.

Dishwasher not cleaning

hello kiwi
check the water level in machine this may be low due to pressure switch not sensing correct level try blowing back through air tube to clear any water from tube then try again
quick way is to start machine and when in wash mode check water and position of arms then add a litre or so of water in mid wash then recheck wash arms if they are now moving then you have water level problem
