Water has flowed over onto floor the last few times the dishwasher has run. Could is be the float switch or any other suggestions
You will want to check to make sure that the spray arms are not clogged or cracked which would cause wave action in the tub of the unit. If the unit does not stop filling with water and overflows then you would want to check the float switch. Check the continuity. If the switch checks ok then it may be the spray arms or the water valve allowing water to continue to come into the unit.
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.
