Re: water not going through spray arms

Have same problem except big motor spins independent of stripped? impeller. tried to reassemble but seems mechanical or adhesive agent misssing from one shaft or the other and the motor spins the impeller (now tight) only to have it slip off again and stop pumping water.

Re: water not going through spray arms

1.does motor run? no. replace motor. door and leave the bottom rack inside dw.spin the spray arm underneath the bottom rack by hand. it should spin freely without binding. if it doesnt spin freely take out the bottom rack and try again. if it does spin freely then your bottom rack is laying on your sprayarm preventing it from rotating. could also not be getting enough water into your dw.

My Kenmore ultra wash dishwasher fills with a little bit of water but does not spray water and does not proceed through the wash cycle. Any advice? We had problems yesterday with blinking lights and not...

The spray arm rotates based on the water pressure coming out of them. If no water pressure, then no rotation. You probably have a clog on the intake hose. You can pull out the dishwasher, tip it forward so you can get to the bottom and then remove the intake hosing to check for debris that might be clogging it. Also check that the arm will spin freely if you spin it by hand, it should.
Let me know what you find. Have a great day.

Dirty dishes

It could be a motor or a pump issue. The dishwasher has a motor that attached to a pump which forces the water up into the sprayer arms and during the drain cycle, it pushes the water out of the dishwasher.
The motor (and pump) located beneath the dishwasher.
Check if motor spins. In case it spins, the problem is with the pump ,in case it doesn't spin it could be a motor problem or a motor and pump problem.

First of all: filter plate clean? Clean any locked hole.
1) Can you remove the upper spray-arm and verify if holes inside are locked by any residus. Clean the holes , and check if pure water come out when you fill the center hole with some water.
2) Switch on the dishwasher , coldest wash cycle dish-washer empty and without the upper spraying arm. Once you hear water streaming in, open the door and look if a little water fountain comes out from the center hole where the upper spraying arm was fixed. If not, this canalisation is blocked and should be cleaned. Try to continue the wash cycle, often the water pressure will clean itself this canal. Check also lower spray arm: it should be rotating a while and ejecting water thru its holes. If not, verify this canalisation as well.

3) Put the spraying arm again on its place, verify also the sealing else water pressure is going down and spraying will not turn and spray water.

4) Again, continu a wash cycle, open the door and look; upper arm should be rotating and some rays trown out.

Hopefully, this helps .

If not, pump pressure may be low; have a repair verify, can be that only brushes in the motor must be replaced, can be the pump worn out and to be replaced at all.

Arms are not spinning

Hello there:
Here is a few things to try ok?
Make sure all spray arm holes, top and bottom, are clear of foreign matter. Does the bottom spray arm turn freely by hand or does it bind? Check under the bottom spray arm to see if the seal (split ring) or the bearing is worn. Check all other seals in the filter system and impellers closely for any wear for if they are swollen. If everything checks out OK and you have lots of water in the unit and the motor is running you should be good to go.
Hope that this is very helpfull for you
Best regards Michael

I have a Beko D 2731 FW its about 4 years old and recently it has begun to leave a gritty deposits. I think this may be due to the top spray arm not running as freely as it used to. I would appreciate any...

Here are a few things to check.

* Worn wash impeller (depending on design). Test by placing a glass upright in upper rack with full charge of water in the basin. Run dishwasher for 30 seconds. Glass should fill up. If not, replace wash impeller.

* Debris caught in spray arm holes. Remove spray arm and clean out with water and compressed air.

* Heating element burned out. Check water temp during wash--should read between 130 to 140 F.

* Insufficient water fill in basin. In most models, proper fill level is just up to the heating element. Much less than this will result in poor cleaning.
Hope this helps.

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!

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!

Maytag MBDF550Aww upper spray arm doesn't spin.

Cleaning the filter was the right thing to try.
Since you don't see cracks/breaks on the spray arm and it appears that it is spinning freely, I doubt that replacing the spray arm will fix your problem.
If your dishwasher is several years old, your problem is likely a failing pump motor, but before you swap that out, check that the impeller is not damaged. Good Luck!

Top arm not spinning

only the top rack isnt getting clean?
there is a little plastic circle in the middle of the bottom of the upper spray arm. turn it counter clock wise to pull the upper spray arm from the upper rack. make sure that isnt clogged and the spray holes are not clogged. otherwise....

the piece that the bottem spray arm plugs into and runs along the back wall of the tank to the top is called a feed tube. pull the bottom spray arm out. now you can see the part of the feed tube that feeds the upper spray arm water. does it pop out freely and easily? if so then you need a new feed tube, if not then its most likely your not achieving the right water level or your impeller connected to your circulation pump(motor) is clogged not supplying enough water pressure to travel up the feed tube to spin the upper spray arm.

possible you have a leak and the bottom tray has water in it. tilt the machine back to 45deg and see if water runs out of the back. if it does, after putting upright, the machine will work - then find the leak!!
