I have a Kenmore Series 80 (8543549) top load washer. It will fill, but not agitate or spin or drain or anything else. The knob does not advance except manually. What component is causing this problem?

Poss. Outlet hose/trap blocked or hose kinked.

The cycle doesn't advance When the cycle doesn't advance, it's probably the timer or a cold-water supply problem:

• It's the timer, if your washing machine fills with water and begins agitating, but the timer never advances--or if the washer is in a spin cycle and the timer won't advance. Then you need to replace the timer.
  
  
• It may be a cold-water supply problem, if the washing machine fills with water, agitates, drains, and spins, but then doesn't fill with rinse water. See There's no cold water.

Warning! To avoid personal injury or even death, always disconnect your appliance from its power source--that is, unplug it or break the connection at the circuit breaker or fuse box--before you do any troubleshooting or repair work on your appliance. Also, because some components may have sharp edges, use caution while working on your appliance.

It doesn't work at all

There's no water at all
The clothes are wet after spinning

The water temperature is incorrect


Hope this may help;

WASHER FILLS WITH WATER, THEN WON'T AGITATE. TURN KNOB TO SPIN AND IT DRAINS THEN SPINS. STILL WON'T AGITATE please show me a diagram

Bad timer. Try to find a used one if possible, this item is a little expensive.
