I have a 2 year old Kenmore Ultra Wash Quiet Guard 3 dishwasher Model No.
665.16014402. Problems started when I noticed a loud noise during the wash cycle for a week. Next thing I know when I tried to use dishwasher another day the green led "Clean" light is flashing. I can't get the dishwasher to do anything no matter what I press. So I call the local service center, they tell me I need a new control panel. I spend a hundred bucks install it myself, it cures the flashing light.

So now I start a wash cycle to test it, dishwasher fills with water but then when wash cycle is suppose to start, I wait and wait, it does nothing. I do notice a humming coming from the motor like it is trying to start but still nothing, so I turn it off for fear of burning motor up. I tap on the motor thinking maybe it's hung up or something, still nothing. I'm a DiY'er but this time I decide to take it to the local service center since dishwasher is only 2 years old. By the way, called Sears to see what it would cost, they wanted to charge $65.00 just to look at it, my local service dealer doesn't charge to diagnose just labor to install the parts you buy from them, so I took it there.
I get a call in a few days, they tell me I need a new motor. Labor plus parts
would set me back another $145.00. I decide to find a motor myself and install it. So I refer to the ever dependable internet and happen along upon this site. After doing some searching in the forums I find out that my flashing clean light is actually telling me that the control senses a fault in the temperature rise during the heating cycle and that the electronic control could be reset by initiating a service diagnostic cycle.

So I install the old control board to see if this could have been the problem.
At this point I'm wondering if the service tech I spoke with on the phone even knew this and maybe told me it needed replaced to make them some money. So I initiate the diagnostic cycle that I got from the schematics and what do you know, brought my supposedly dead board back to life. Now I'm wondering if the motor is even bad. According to my schematics the diagnostic cycle is suppose to last 16 minutes 15 seconds but it doesn't. At approximately 3:30 the dishwasher shuts off, no leds lit, nothing. I restarted the diagnostic cycle several times and it always turns off after 3:30. If I'm reading the schematics right, at about this time the motor is suppose to activate. I remove the motor, it turns freely. The water pump impeller seems to be turning freely.

At this point what else do I need to check? What setting do I set my digital multimeter to and how do I check my motor with it. My motor has a capacitor attached to it by the way. Also where is motor relay and how do I check it? Any help would be greatly appreciated?

If the noise in the motor start all of the sudden it was like something in the pump.

If the wash impeller got jammed it could have ruined the motor and this would have cause the light on the panel to flash.

To check the winding in the motor make sure you disconnect the capacitor.

The resistance of the run winding should be 3.7 ohms.

The resistance of the start winding should be 6.25 ohms.

Use you wiring diagram to determine the two windings.

The relay is a part of the control board.

You should ask the service person if they took the pump apart and ask if they found any thing in it just so you know.

Here is a list of parts for your dishwasher model 665.16014402.

I'm not sure what you mean by the winding. Are you talking about the copper wiring inside the motor? I see on the diagram where it mentions Run Winding and Aux. Winding but I don't know where to put the probes from my multimeter.

Ok, I disassembled my motor, it turns freely, doesn't appear to be any kind of charring, burn marks, etc. I've tested the windings and I get a 4.6 on the run winding and a 6.8 on the start winding. I also checked the capacitor and get no reading on it. Is this normal?

My Kenmore is a 665.16879000 and is doing exactly the same thing. Fill cycle completes, then motor hums but does not start. Wondering if you found anything else after your motor winding resistance checks?

[lgmccoy1]

No I haven't I gave up trying to troubleshoot it. Just going to take the tech's advice when I first took it to them and buy me another motor.

Good luck. I ended up fixing mine by just freeing up the motor. Apparently it had become bound up, either inside motor or pump. I took out the screw that anchors the motor to the pump housing, rotated the mtor housing free of tabs, then reached in the back of the motor with a small screwdriver and rotated the armature a few times. It seemed to be bound up and rotated with some effort, but then broke free. I re-aligned the motor and put the screw in, then buttoned everything up and it works again. Since you indicated your motor spins freely, I assume you have a different root cause.
