Washer occassionally overflows WATER DOES NOT SHUT

see this causes and fix it. God bless you
Water Inlet Valve If the washer is overflowing and power is shut off to the washer, the water inlet valve has failed. Replace it.
Pressure Switch If the washer is overflowing the pressure switch might be defective. The pressure switch is attached to a small tube which is attached to the outer wash tub. As the water level rises the air pressure in the tube increases, once the set water level is reached the pressure switch turns off power to the water inlet valve. Check to be sure the air tube to the pressure switch is clear before replacing the switch.

Low Water Pressure from House Supply If the washer is overflowing the water pressure to the water inlet valve might be too low. The water inlet valve requires a minimum of 20 psi to shut off properly. If the pressure is lower, the valve may not close fully when the power is shut off. This results in the valve leaking water into the washer and causing it to overflow.

Hi.... you have a water valve that is not working right

I don't come to this forum very often. Did you get help with the issue? Sounds like a Stuck Open Water inlet valve sorry for the late response.

1. Water inlet valve. It may not be able to shut completely when the electricity to it has been turned off. The valve may leak and drip water into the clothes tub. Water may accumulate substantially and overflow. Remove the washer's cabinet to access it.
   
2. Water level switch. This switch senses the water level in the clothes tub. It is usually a diaphragm device with a small clear tube attached between the switch and the bottom of the washer's outer tub. As the water level in the tub increases, the air pressure in the tube increases and activates the switch when the water reaches a certain level. When the switch is obstructed, it cannot tell the water to shut off and the machine overflows.Clear it from any obstruction.
3. Air-hose. It is connected to the water level switch through a tube. If the tube or hose is cracked or broken, no enough pressure builds up to trigger the switch and shut the water supply off. Check it for any obvious damage.
   

You may have missed something when putting it together. Take it apart again then check and properly install the following:

There should be a dome shaped float switch on the inside bottom of the washer. Make sure it is free to move up and down, or is able to float (possibly cracked or broken).

you need to replace the inlet valve something is stuck in the valve not allowing it to shut.

This is a fill valve gone out

If it only overflows while the washer is running, check the pressure switch, or water level switch. The hose may have come loose, or could have a hole in it somewhere. Otherwise the switch may be stuck or may need to be replaced.

If it's overflowing when the washer is off (i.e. in the middle of the night when there is no laundry in it), then check the water valve.
