Turn the circuit breaker off to the pump. Undo the band that holds the motor and flex plate to the pump. Unscrew the 5 screws on the diffuser ( front of pump ) That will expose the impeller. Remove the rear cover of the motor, (2 -1/4" screw heads) Pull off the rear cover. The impeller might have a screw in the center of it. If it does, the screw is left handed thread. Turn the screw clockwise to remove. Use a 7/16" open end wrench to hold the shaft at the rear of the motor. Put the wrench behind the plate with the two springs on the shaft. You might have to turn the shaft a little to get the wrench on. Remove to screw and remove the impeller, (counter clockwise). Unscrew the 4 motor flange bolts and pull the flex plate from the motor.

If the dishwasher is making a loud whining noise, the drain pump or motor bearings are defective, the drain impeller or wash impeller might have worn out. All these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.

My top sprayer wont turn or shoot out water

Check inside the spray arm does it look like its clogged with food? If not then it might be clogged in the motor and pump assembly. If you open up the motor and pump assembly and you dont see that it being clogged up your motor and pump assembly needs to be replaced. The motor is weak and not giving enough water pressure to spin that top spray arm. It might not be worth fixing cause of the price of the part and difficulity of the job.

Cadet 5' x 36'' Whirlpool white 2771.018W. Bath is filled, turn on, buzz for a few seconds stops and dosen't do any thing. After a few minutes buzz again as if it wants to turn on but nothing.

From the sound of it the pump has seized and the thermal breaker is tripping causing the off and on buzzing sound. The problem could be in the motor or the pump attached to the motor. The easiest way to check this is to pull the pump/motor assembly out and check the rotation of the impeller. The impeller should spin freely with no drag. Most pump/motor assembly have a screw slot in the back under a plug or just open in the middle of the back of the motor. In some cases this test can be done without removing the pump/motor assembly. If the motor and pump do not spin freely, puchase a new pump and motor as one unit..

Dishwasher not draining and making a noise

Ok, normally, when you hear abnormal noises and the draining has stopped, this will point to the pump/motor assembly. this assembly , basically, runs together in unison. the pump/motor are as one and if the motor is malfunctioning, the pump will not drain properly. this noise is coming from the pump housing. There are many parts that are located in this housing and one fragile part that can cause issues is the Impeller. this piece provides the pump action that moves the water during drainage. If the sleeve that connects to the Impeller becomes stripped, the motor drive bolt will simple spin freely, causing this noise and no drainage. The motors fine but, you will have to replace the pump assembly in order for this noise to stop and the normal draining cycle to return. just to be safe, check all the drainage hoses as well.

please rate and god bless:)

Unit not pumping on wash cycle

Could be bad main wash pump motor, bad capacitor on said motor, or broken or jamed pump impeller. You will need to remove the lower spray arm and filter assembly to get access to the pump impeller to see if it is jammed or broken. If you can turn the motor shaft but the motor just hums then the motor of motor start capacitor is gone. You can order the motor with start capacitor and impeller for around $130. Check for 120v at the motor terminals prior to replacing motor/pump assembly to confirm, 120v at motor would but motor not turning equals bad motor and or capacitor.

The only reasons to replace a pump motor are very loud motor or leaking water from the seal of the pump / motor assembly. The motor comes as the pump / motor assembly, and is not real cheap and not particularly easy to replace, so you may want to consider cost of replacing the entire unit. Appliance repair locations can order for you, or you can order directly from GE over the phone. (GE answer center 800-626-2000) Make sure you have complete model number, located on the sticker on the left side of the tub just inside the door.

Motor-Pump Drive assembly is defective.Hey while you have this machine apart pull the drain pump off and look for a jammed flap,it's rare but check it anyway.(to remove the drain pump just twist it and pull it off).For the non believer's out there ,this will be a learning experience.You will NOT resolve this "not clean dish" problem unless the Motor -Pump assembly is replaced with the one they now make that works. THIS to some repairman was called POWER DRIVE ASSEMBLY. Quick note: motor - pump does NOT include the drain pump.Think about that for awhile.Any way the drain pump will not be the problem,the Motor-Pump is!
