Hello Enricko, I'm sorry but we will need to ask you to post a new question including the model number from your units' I.D. tag so we can recommend test procedures and parts that can be guaranteed to work properly on your unit. Thank you for your patience and understanding in this matter.

Johnny, You use a resistance reading (ohms) Place the meter leads across the terminals, the display or indicator should deflect towards a "closed" circuit(infinite resistance) and drop back down to an open(no resistance) circuit, if it is good.

Ken, The capacitor would not cause the motor to not run. This sounds like it is a faulty motor on the unit which will need to be replaced.

Charlie, This would be more likely a motor issue rather than a capacitor if the capacitor checked ok when testing.

Frank, It would be recommended to pull the pump off the front of the motor and then try to put the unit into a spin cycle and see if the motor just hums or check to see if the motor turns. If it turns then replace the drain pump which will be the most likely cause since the unit is not draining. It may have something clogged in it or is just seized up.

James, Yes, you would want to start at the lid switch WP8318084 if the switch is faulty or not making contact properly, the neutral side of the circuit will not be completed and the motor wont run. Also check the lid hinges and sleeves, make sure they aren't worn out or loose and causing too much movement or play in the lid and loosing alignment with the switch.

James, You will want to check the pressure hose and air dome to make sure that it is not clogged up The most likely cause for this issue of intermittent operation sounds like a loose connection. This also could be a timer that the contacts are sticking causing power to agitate and spin at the same time.

Based on the noise, I assumed that there was probably a problem in the gear case. However, based on the fact that the motor now doesn't run (the machine is disassembled), I thought I'd try a new capacitor (not expensive). I don't know if the motor is OK, however there was no burning smell when the machine died and I disconnected it immediately after the agitator stopped. I want to verify where the problem lies before I buy any more parts, but am trying to figure out how to check the motor and the gear case. The coupling is worn and should be replaced, but it was basically intact.
