Why won't washer not spin or agitate during wash cycle?

gabehart....sounds like belt is slipping. Replace it. The water pump is on a separate smaller motor so is not affected by the agitator/spin motor.

Hi this could means that you may need to replace the washing machine bearings. Once the bearings are bad, the motor overheats and it will automatically shut down after the first rinse.

When the washer initially fills for the wash, is it only hot water entering the drum? Try switching the water temperature between hot and cold as it fills. If any of them show little or no water getting through, it sounds too easy but check to make sure water supply taps are on, and that the cold/hot fill hoses aren't reversed. Remove the fill hoses and check any of the screen filters for blockage (in the hoses and in the inlet water valve). When the machine stops and waits to fill but all you hear is a hum, it sounds like there is power going to the valve but water is not able to get through it.
Good luck!

Check the lid switch. Through out time the lid switch housing can come apart from years of heat and cold. When I checked mine, I found the glue deterriated and the housing came apart. What I did to fix it is I zipped tied the housing together and did a functional check and it worked.

CHECK THE LID SWITCH THE PART THAT PUSHES THE SWITCH DOWN MAY BE WORN ENOUGH TO CAUSE THIS PROBLEM. WITH THE LID OPEN START THE WASHER IN THE SPIN CYCLE AND PUSH THE SWITCH WITH A POPSICKEL STICK AND SEE IF THIS PROBLEM STILL HAPPENS
