I have a Samsung dishwasher (don't know the model number) that throws Normal and Heavy code as soon as it starts filling. This is an overfill code. I have 1) replaced the drain hose, 2) disconnected the drain hose and drained to a bucket (drains fully and completely), 3) replaced all the under sink plumbing just in case, 4) opened and cleaned all the drain components in the wash tub, 5) removed the side panel to make sure that the water is not reaching the fill sensor (it is not). The unit starts, drains, and as soon as it starts to fill, it throws the code. This is BEFORE more than about 1/2 inch of water enters the sensor compartment and well below the level that should trip that sensor. Any thoughts?
