My dishwasher drains quickly but after it drains the pump won't switch off, and then starts beeping and flashing the delicate light. I have reset it, and still the same... The drain pump kicks on and humms with no water until it trips the error code and flashes the delicate light.. It sounds like the float sensor from what I've researched, but I'm not familiar with dishwashers.
For model number MDT24H3AST
Hi Casey, thank you for your inquiry. According to the description of the issue, you will need to replace the water level switch, part number PS18189266, to fix the issue. The float switch is a small plastic component that looks is located in the bottom of the dishwasher tub. It rises with the water level and is connected to the anti-flood sensor beneath the tub. Glad to be of help!
