Kenmore washer won't stop fillup
Recently, the washing machine started overflowing back out the drain pipe. To prevent this, rather than snaking the drain, we wrapped duct tape around the overflow tube to the drain pipe to prevent the water from overflowing. This worked for awhile, but eventually the water started backing up in the machine itself and overflowing the bowl. Now the washer's fill cycle does not stop.
Even if you put it on the lowest load setting, it fills all the way to the top and over the side.
I'm wondering what the problem is with the fill sensor. Could it be shorted out due to the water overflow?
It's a Kenmore series 80 purchased new in 2004.
Thanks in advance for the help!
