What causes washing machine to overflow?

One thing that hasn’t changed a lot is the pressure switch on your washing machine. It’s this switch that stops water flowing to the water inlet valve once you’ve reached the desired water level. If it isn’t working correctly the water inlet valve will continue to feed your machine causing it to overflow.

Why is my washing machine filling up with too much water?

One of the less common reasons your washer may be overfilling is that there is not enough water pressure for the water inlet valve to work correctly. If there is not enough water pressure, the water inlet valve will not close completely, which can cause the washer to overfill.
