No Spray The cleaning in my dishwasher has gotten slowly worse over time. I opened up and checked all spray arms ( all clear). Then removed filter and cover plate near pump. It was very clogged with food particles and ALOT, ALOT of hard water build up. Cleared it all out, but it appears that the spray arms are not working. During cycle,when door is opened quickly all I see is a little bit of water dribbling out of bottom wash arm holes. It appears that there is very little pressure. I am wondering if it is difficult to remove the rest of the bottom area to check for mineral build up. There is a seal around the bottom and if I remove much more it may be a problem getting it all back together the correct way. thanks in advance, Duck

Hi

Please check if something is blocked near the top spray arm, also make sure that all holes are open. Use a sharp metal pin to clean the holes on the top spray arm. Make sure the water pressure is not low.

under the screen and you'll need a Torx screwdriver to get to it after you remove the spray arm and screen. Check to see that the path it travels is clear. I have seen these get blocked up by stuff.

Now check if the top arm spins freely and check the bearings for the arm, if they are producing extra friction while the spray arm spins. Hope this helps... Please post back if you need more assistance.

you may want to check your hot water tank. It may need drained and cleaned, Or you may have the rod in the tank disintegrating. Also check you water faucet areators to see if they have calcium pieces too.

Carefully inspect the lower spray arm for a crack or separation.
Also inspect the holes in the spray arm that may be stopped up with debris.
Remove and clean the filter in the front center of the tub.
Set the spray arm at the 12 o'clock position and start the washer. After 30 seconds open the door and check the position of the spray arm. Do thi several times to confirm the spray arm is rotating.

could be the plastic shaft extension that screws onto the motor shaft to drive the pump. The threads on the plastic extension would sometimes get stripped out so that even though the motor is running, it isn't driving the pump mechanism. Assuming the dishwasher is filling with water and motor is running during the wash cycle. also check spray arm openings to make sure they aren't plugged up.

Hello there:
There are 6 areas that could cause this to happen Please follow these simple steps ok
Investigate each of these six areas if your dishwasher is not completely cleaning your dishes:

Water Inlet Valve

A dishwasher's water inlet valve is its most common part to fail. When your dishes are not being fully cleaned, quite often a faulty water inlet valve is to blame. Test your dishwasher's water inlet valve, and if it is no longer functioning as it should, you will have to replace it.

• Find a dishwasher water inlet valve.

Upper or Lower Spray Arm

Your dishwasher has a lower spray arm. It may also have an upper spray arm at the top of the dishwasher. These spray arms are designed to shoot high pressure, high temperature water at your dishes. It is possible that the holes of the spray arms, where the water comes out, are blocked with debris, affecting wash quality. You should inspect your dishwasher's spray arms regularly. Clean out the spray arms as need be.

• Find a dishwasher spray arm.

Heating Element

Water temperature is a key element in achieving clean dishes. A dishwasher's heating element is not designed to heat the water that enters it. Rather, the heating element is designed to maintain the heat of the water that enters the dishwasher. Its a good idea to run the hot water in your sink for a couple of minutes before you run the dishwasher. Just to make sure the water is nice and hot before it enters the dishwasher. If the water is unable to stay hot, it can adversely affect your dishwasher's cleaning ability.

• Find a heating element for your dishwasher.

Filter/Drain Grate

There is a filter in your dishwasher. Its function is to keep large particles of food and foreign objects away from the pump. Many of the newly-manufactured dishwashers have self-cleaning filters, and routine cleaning isn't a concern. However, some other dishw ashers need to have the filter removed and cleaned regularly. If the filter or grate is clogged or blocked with debris, it may interfere with the normal functioning of your dishwasher. Consult your owner's manual for specific directions for removing your dishwasher's filter and cleaning it.

• Find a filter for your dishwasher.

Detergent or Detergent Cup

It could just be that you aren't using enough soap to completely wash your dishes. Your dishwasher may be designed to dispense soap at two different times during the wash cycle. If you don't fill all of the detergent cups, then the diswasher will lose a cleaning cycle. Also, if you use a gel-type detergent, try switching to a powered kind. Powders tend to dissolve better in hot water. And don't buy in bulk. Detergents are most effective in the first two weeks. After that, they decrease in potency.
Alternatively, your dishwasher's detergent cup could be defective in some way. It is possible that it is gunked up full of built up detergent, and a thorough cleaning may be enough to get it working again. If that doesn't do the trick, you probably need to replace the entire detergent cup assembly. If your cup isn't even opening, please see our section My dishwasher detergent cup won't open.

• Find detergent dispenser parts for your dishwasher.

Cycle Selector Switch

Sometimes a dishwasher's cycle selector switch is the reason why dishes are not coming completely clean. Test your selector switch to determine whether or not it has become defective. If it has, replace it.

The top rack is not cleaning because of low water pressure from the wash motor to the upper spray arm.
Assuming the top spray arms are clear of debris, remove the lower spray arm to access the wash motor. Remove the 4 torx screws and the filter (accumulator assembly). Remove the torx screw and the inlet protector that covers the chopper assembly. Make sure the chopper is not broken (broken chopper will fill with debris and block water flow). While holding the chopper blade, reach inside the "D" shaped opening on top of the motor and spin the wheel/motor by hand in each direction to make sure either the chopper gear or the motor gear that drives the chopper is not broken. Replace the chopper if necessary (part # 8268383). If the motor gear is broken, replace the sump and motor assembly (part # 8535150). Remove any debris from the sump area in the process.
You don't have to because the door will be open, but if you feel more comfortable shutting off the power to the dishwasher, do so.
Good luck!

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

open the door when working and check the spray arms are rotating. if not, the jets in the spray arms may be blocked. very fiddly to clear but doable
