Kenmore heavy duty 70 series model 110-8237012

It could be the clutch or the gearbox. It can be repaired, but top loaders are old dinosaurs these days. Front loaders are as big or bigger, and more efficient and cost a fraction of the cost to run in water and electricity for heating that water.

Series 70 is just that, a series. A model number will give you the cost of spares and how many have been discontinued?

Yours is a 2 speed motor. Does it spin in 2 different speeds. If so, then it most likely is designed with only to agitate in 1 speed. If it only spins in one speed, then your motor is defective

Sounds like the inlet valve is leaking you can get a replacement from sears parts. You need the Model number to look up the part

It could be a dry rot hose or the pump could be leaking might be an easy fix it depends whether you want to repair it or spend allot of money on a new dryer are u pretty handy i could assist you on how to fix it .

If you bought a new washer and you still have a leak, i guess it was not the washer but where it drains into. Sink or stand pipe has a leak. unless you are useing the old drain hose from your old washer. Dry up everything and look for the sorse of water with a bright light when the washer drains .

its a filter inside the water hose thats still blocked or the relay inside the washer for the cold feed is not opening up fully it could just need a clean or maybe a new one fitted

NEW WATER PUMP

Probably the drain pump seal has gone bad.
Check it for leaks.
If your floor is good and level look for water near the front center of the machine.

remove fill hoses and inspected for debris or cloggs ,,,,

You have leaking water pump.
