The washer is overfilling when used on super. The pump was replaced earlier this year, with no other problems since then. All other fill levels seem to be fine. What is wrong with this now.

Thanks

Your water level is actually controlled by air pressure. There is a tube that runs from the water level switch down to the bottom of the tub. As the tub fills air is trapped in this tube, as the water rises the air pressure in the tube rises and when it hits the water level set point it shuts the water off and starts agitation. So a number of things can cause your problem.

Open up the control panel.
1. Blow into the tube. It could be some crud is partially blocking the end down in the tub.
2. Check the tubing for cracks/holes etc., which may be allowing some of the trapped air to escape.
3. Cut off about 1/2 inch of the tubing, it may be leaking at the level switch.
4. The level switch is sticking and requires replacement.
