My dishwasher overflows on the last rinse. The float works and the switch is ok. What else will cause it to overflow?
Answer Hello Phil,
There are a couple of things that I would suspect. The water valve could be sticking, causing a longer fill than designed. The water pressure could be low enough that if someone is washing their hands or otherwise using the water, there isn't enough water pressure to close the valve. There could be an over soap situation. The bubbles will jump the air gap at the bottom of the door and pop before they hit the floor, appearing to be a simple water leak.
Let us know if we can answer any more questions for you.
When I added hot water to the start of the cycle it cleaned much better especially for the top tray. Suspect not filling with enough water. What part would cause this problem?
Answer Chas, the most common issue for your complaint, is a clogged fill valve W10648041 debris and sediment from the pipes enter the valve and reduces the water flow into the machine. You do want to check the float assembly, manually raise and lower the flaot, make sure it moves freely, and you can hear the water level switch "click" then replace the fill valve. With a proper operating float and fill valve, the water level in the bottom of the tub, after a fill and three to five minute wash, should be in touch with the bottom of the heater element. Thanks and Good Luck
