Having problems with your Dishwashers ?

I had a service tech at my house to repair my refrigerator. He also took a look at my Maytag WU504 dishwaser, which was not cleaning the dishes anymore. He was less familiar with dishwasher diagnosis, but found that the lower spray arm was pumping out water through the jets properly in the cycles, but that the spray arm was not rotating. He seemed stumped and called his supervisor, who suggested it might be the wash impeller. I have looked at the parts diagram on partselectdotcom and taken t

Both spray arms of my DU943PWKQ0 do not turn or spray. The motor is moving and the it drains without problem. During the wash and rinse cycle I can hear the sound of water, however it doesn't clean at all and the sprays arms stay where they were. It seems the motor only creates no spray, but wave. I powered cycled the dishwasher, the problem remains the same. Anyone know what's wrong with it? Thanks James

The cycle doesn't seem to stop correctly. I start a load. It doesn't seem to matter which mode that I start in, but it will count-down the time, but at the end it hasn't stopped running. I've cleaned out the filter and the trap below. I've ran vinegar through a cycle. I've cleaned all of the spray arms. It doesn't seem to advance out of the wash mode. There is still some suds at the end. I have to end the cycle by canceling and draining it manually, then run a couple of "rinse--9 minute" cycles

Component failure Actually a Kuppersbusch IGV 645.2 Dishwasher There is a plastic conduit which takes water from the base of the machine to the upper spray arm. This now comes adrift from its connection at the base (behind the lower spray arm) on every cycle, resulting in poor or incomplete washing. It can be replaced easily and seems firmly inserted when done but is always adrift again by the end of the next cycle. Anyone any ideas?

Hi, I have an LG LDS4821 dishwasher and it appears to stop working properly. The dishes don't seem to be cleaned at all. It seems like the spray arms are not spraying the dishes as the dishes are still dry/dirty after a normal wash cycle. I did notice that the detergent was used during the wash, and a trail of white residue was at the bottom of the tub. I can hear water pumping into the dishwasher, but when I opened it during a wash cycle, there was a puddle of water at the bottom of the

Noticed dishes on top shelf not entirely clean. Ran machine empty and opened many times during wash. Noticed that Lower Spray Arm works as expected, but Middle Spray Arm turns only 1/8 or less, then Lower Arm spins again. Schematic with Use and Care manual just says pump motor switches from one to the other in certain cycles, but I don't see this happening. Looked for obstructions to water flow and pressure seems normal. Is control for this function part of the pump, or in the control panel?

My Kitchen Aid KUDS01FLSS2 dishwasher does not spray water thru the wash arms nor do they seem to turn. Additionally, one of the the bottom arms hits the "cap, internal rear feed" where it clips to "feed tube assembly" when rotated by hand. The spray arm assembly appears true on visual examination. The unit fills, cycles and pumps out in an apparent normal way. While on this site a while back I was advised to clean the unit and referred to a downloadable repair manual that was, in fact, not

Dishwasher, nautilus, doesn't spray water out the top arm? I'm haivng to wash dishes 2 times, and still no better results. I've tried opening the door fast during a water cycle to see which is the problem - can only figure it is the upper arm, the lower arm seems to have water coming out, can't tell if the tower raises completely up.


The jets on the arms can sometimes get blocked with food bits that have got past the filter. This reduces the water flow and rotation of the arms.The arms are easy to remove without tools (they are intended to be removed by the user). ... GE Nautilus 24" Built-in Dishwasher

My Kitchenaid ModelKUDI01TJBL0 only leaks at initial start up. Just after the water fills, the first few seconds of the wash cycle. It pours out the front door for a couple seconds than no more for the rest of the wash. It is level, no cracked arms, or loose pumps.Splash guard is in place. The float seems to be working, not too much water in the bottom. I am stumped.

My Kitchen Aid KUDS01DJSS0 seems to have water going to the upper spray arm (I see water coming out of the unit just beneath the upper rack), but the pressure doesn't seem to be high enough to clean the upper rack. No evidence that water is coming out of the spray arm on the very top. Lower rack dishes seem to clean OK.

My dishwasher makes a banging sound, I've checked the arm & even when the washers is empty it still makes that sound.

Bosch Exxcel model number SGS46E12GB had the check water light on a week ago, checked supply and cleaned filters, all good. light still on, got upset and slammed the door, light off. since then the unit will either wash stuff, or not. didn't seem the arms were spraying very well when I opened the door, so I bypassed the door switch tonight and put it through a pre rinse cycle.

Whirlpool dishwasher doesn't seem to fill with enough water despite good water pressure. Therefore, pump sounds like it is cycling from pumping water for about 2 seconds to going dry for 2 seconds to pumping water for 2 seconds to going dry for 2 seconds, etc. Spray arms rotate only for the 2 seconds when pump is actually pumping water.

Our Bosch dishwasher (model unknown) collects small rock-like deposits in the ends of the top spray arm. From what I've read, these could be calcium or other mineral deposits.
