Question about Zanussi ZT485 Built-in Dishwasher

Lower arm spinning slow/intermittent

I have cleaned both spray arms and filters and have run the machine with the door open. The lower spray arm spins slowly and intermittent. If I run it with the arm and filter assembly out, the water jet pulses. I would imagine this should not pulse but be constant. Also the upper spray arm does not spin at all (on a quick cycle). Any ideas.

Running with the door open indicates another fault that could be dangerous unless you have bridged the catch for testing only, water should flow fast and forceful at all times that it circulates, through both spray arms at once, you have to look for blockages in the system, is the waste outlet pipe high enough, this allows the machine to fill adequately so it doesn't pump intermittently, i doubt very much this is an electrical problem hope i have helped a little

Top spray arm doesn't spin


The filters are probably plugged. This will require removing the lower spray arm and cleaning the screens or its possible your not getting enough water in the dishwasher which will cause th upper spray arm to not turn

LG LDF6810ST dishwasher won't clean and spin arms properly


Check for a worn bushing washer on the lower arm. Also, make sure the arms are clean inside - they are propelled by reaction from the water jets spraying out, and clogs will prevent proper water flow through the jet orifices. Sometimes food debris will get through the pump and cause this problem. The diverter valve may also have trash inside clogging it and keeping from seating properly - this could account for both low pressure at the spray arm and water coming out of the lower rack when it should not.

After filling and only when rinse commences a loud chattering noise begins. Somewhat like a circuit breaker making intermittent contact. It ends when I cancel and remains silent while the pump empties...


  • It sounds like you have an obstruction with upper or lower spray arm. check to see if the something is stuck in the path of the lower spray arm.
  • move the lower rack out
  • spin the spray arm by hand to see if it is hitting anything
  • if not .....spin the upper spray arm by hand under top shelf to see if it is hitting anything.
  • let me know how this works

The top shelf is not getting clean. There is food residue on the glassware that was not there at the start of the wash.


Hi,

The most likely answer is that your upper rotor spray arm isn't spinning or spraying water. They aren't powered by a motor - they are driven by water pressure. The most common reason for them not spinning is a blockage somewhere. The lower rotor arm is spraying dirt from the plates in the lower rack onto the glassware and there is no spray from the upper rotor arm to rinse it off.

Check the small spray holes on the top of the upper rotor arm. If they are blocked, use a large pin or a cocktail stick to clean them out. If they aren't blocked, check to see whether the upper rotor arm is spinning by following these steps:

1. Note the exact position of the upper spray arm or spin it so that it is running precisely left to right or front to back
2. Close the door
3. Start any wash cycle
4 After it has finished filling with water and starting cycling the water, open the door and note the position of the upper spray arm again.

If the spray arm is in the exact same position as when you closed the door it's almost definite that it's not spinning. In this event, cancel the wash and do the above test one more time just to eliminate the element of pure chance.

Try the above tests and checks and then post back with the results if you need any further assistance. If posting back, please include the full model number of your Frigidaire dishwasher

Regards,
BElectric.

Moyer Diebel Dishwasher arms are not spinning and doing lousy


Hello there
First to check is the water level is it just cover the round filter and no more, or is it much lower from the filter. It seem you have not enough water in the tank to do the washing that is why you have a lousy washing job, not enough water to spray upwards don;t talk about the top spray arm , the water doesn't reach there at all.
You can check it out by manually fill the machine with water up to the filter and start the machine up when the machine is running open the door and you can see the water spray up to the top be careful the water will spray out to your face too.
This is only to check to see the motor is running normally.
If the water level is good ( that is just touch the filter) and the problem still there, then the other cause the problem will be inside the pump motor the part call the impeller may need changing.
Do you have the manual book so I can show you which part we're talking about and let me know where your district so I can tell you where to get the parts from . My email address is dickson@lau.com God Bless Have a nice day, Dickson

The arms do not spin and no water is going through them


Switch to a brand name powder detergent like Electrosol or Cascade. Never use ultracheap, generic DW detergent powder in any dishwasher. Run a load with dirty dishes and see the results are.

If cleaning results remain poor open the sump area by removing the lower spray arm and the filter assembly. Remove all debris in and around the sump area. Inspect the impeller down there to make sure it is not broken and that it spins freely. Clean the filter well in the sink. Reassemble. Also, check all spray arm holes for blockage.
Run a load of dishes and check cleaning results. If problems continue, you almost certainly have a failing wash motor and replacement is your next step.
Post here is you would like more assistance. Good Luck!

I have a kenmore 665 dishwasher where the spary arms do not spin.


  • First, check water level. Start machine, wait until the machine begins main wash. Open the door, the water level should be just below the heater element. If too low replace inlet valve.
  • If you can't hear the wash motor running or is just humming, the motor may be bad.
  • To check if the food chopper is blocked or broken;
  1. Remove lower spray arm by holding the arm and rotating the spray arm retainer.
  2. In the back of the tub, unclip or remove the screw from the upper spray arm supply tube.
  3. Rotate the lower spray arm support to the right while disconnecting the supply tube from it.
  4. Remove the four torx screws from the sump cover, remove assembly.
  5. There may be a primary filter in the left side of the sump, if so, remove the torx screw and the filter.
  6. On the right side there is the chopper assembly cover. Remove the torx screw and cover to expose the chopper.

Hope everything goes well for you,

Regards

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.
