Frigidaire washing machine overfills

If it fills with water and starts the cycle and the water keeps running in then your water inlet valve on the back where the water supply comes in is sticking. It needs replacing. This is also the problem if it happens sometimes.


Your pressure switch stops the water and allows it to start the next cycle. It's a switch either in the control panel or at the top of the tub with a small tube connected to it which goes down between the inner and outer tube. As the water level increases the air in the tube is compressed until there is enough pressure to make the switch stopping the water from filling. This tube can get clogged and the switch won't work. Remove the tube and clean it out. Blowing on the tube when it's still connected to the switch will make the switch if it's working and clear.

You are correct. Sounds like the pressure switch is broken or leaking and may need to be replaced.

To replace it, the back of the appliance needs to be open, there is a plastic tube that is connected to the tub and to a shiny round piece. That part is the pressure switch. It should have a part number engraved so it can be used to order a new part.
