Removing a wash impeller on a Kitchenaid KUDSE124 dishwasher; about 20 years old.

KitchenAid Dishwasher Model KDS 20 KDS20 KDS 20 Parts

Hi, if the water doesn't drain from your dishwasher, check the drain line and pump..

A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again.

Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.
Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.

Do you hear a humming sound, like the motor trying to run, then stopping for a minute or two before trying again?

Usually, dishwashers run the motor one direction to wash, and the opposite direction to drain, but some use a valve to switch. If you see wires going to a bulky flapper looking part sticking off the side of the pump/motor, you might have a bad valve actuator.

Otherwise, you might have a motor refusing to turn in one direction. You can usually access the shaft from inside the tub by removing the washer arm to get access to the pump impeller. Do not remove the impeller unless necessary, but see if it will turn both directions. Broken glass or pieces of bones or other debris might be interfering with the rotation. If it turns freely both ways, but still won't wash, it is likely you have a bad starter coil on the motor, and will need to replace the motor/pump assembly. These usually have a longer warranty than the rest of the unit, so if yours is less than 5 years old or so, it would be worth checking with factory service.

Hi,

• A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain.

• Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.

• Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.

• Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water.

HI. the wash impeller is damaged. this will cause much noise during the wash and it will affect the nature of the wash dramatically. this impeller is attached to the circulation motor under the sump. it should be replaced asap, if possible.

HI. this sounds like a busted impeller in the pump housing. there are two impellers. one for the wash and one for the drain. the drive shaft will strip the impeller center nut, causing this noise. I would inspect the pump housing for lose impeller action. replace the faulty impeller if found to be damaged.

OK, that piece of glass may have jammed the wash impeller. this will destroy the motor windings. you will need to gain access to the circulation motor asap.the impeller is attached to the motor that is housed within the pump casing(upper). try to manually move the impeller. if its stuck, try ot remove the obstruction.

It is possible that, the motor is already damaged to the point of no return. in this case, replace the circulation motor. your drain pump should be ran by a totally separate motor(wax).


**NOTE

Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

Yes, you are at the point that where the wash motor needs to be replaced. There is no magic bullet to avoid doing the replacement.
If you want further guidance, please post back here. Ok?

If this LG LFD6810 dishwasher is less than 24 months old, the parts are still covered, just not the labor.
Recommend you contact LG service and discuss your failed wash motor.
And yes, because the impeller (and the motor it is connected to) does not spin freely, it is the culprit.
Good Luck!

Either:

1. the water does not get into the dishwasher open the dishwasher 3-4 times during cycle, you should see some water at least once, if not - check water valve, water level float and water pressure.
2. the pump is clogged - there is water, the motor will run but no water is circulated. Check pump filters, check chopper and impeller.
3. motor in main pump is not working - could be caused by something stuck on the impeller or chopper or could be a problem with the motor itself or control board. Check if line voltage is coming to the motor during wash/rinse cycle.

Good luck,
