I am writing with a possible resolution to an oE (over level water) error code. The manual suggests shutting off water and power and contacting a service tech should you get the error. I got the error a month after the 1-year warranty ran out. I looked around but couldn't find much in the way of a solution for this model. I removed the interior drain assembly and cleand it thoroughly. It was disgusting. I reassembly and re-installed it. I was able to run the dishwasher through one cycle, but got the oE error on the second attempt. It took the drain assembly apart and cleaned it again with the same result. I finally removed the dishwasher from under the counter and found the float and sensor for the water level. I revoved this assembly and cleaned it thoroughly. I used wire brushes, pipe cleaners, and drain cleaner to clear the clogs. I also cleaned the tubes that connect to this assembly. They were rather plugged as well. I reassembled the unit and it is running fine now. I am going to attempt to run the sanatize program more often and make sure that we don't leave dirty dishes in the washer for extended periods of time. Hope this helps.

I just had this same problem, and I think I figured it out. There was water on the bottom from the last cycle, so I pressed HEAVY and DELICATE at the same time for 3 seconds (you'll see it printed on the control panel), and the unit drained. I was then able to start the new cycle normally without the error. Hope that helps!

Hi If the water inlet
valve is fine and it fills with water then the issue seems to be with the float
switch assembly that is bad and should be replaced. Float assembly is found
inside the dishwasher's tub, on the bottom. The water that fills the dishwasher
lifts the float, and when it reaches a certain level, it acts as a trigger for
the float switch. The float triggers the float switch to shut off, thereby
shutting off the flow of water into the dishwasher. A defective switch may
interfere with dishwasher's filling and/or draining ability. Use voltmeter to
test the switch. Set the device to the ohms setting x 1. Take each probe and
touch them to one switch terminal each. This should produce a reading of either
zero or infinity. Continue to touch the probes to the terminals, and press down
on the switch's button. The reading should change to the opposite extreme. If
the switch fails either of these tests, you should replace it. Hope this helps...please post back for
further assistance. Daniel

A Samsung service tech showed me how to fix this one. You can take that float and the white box apart from the dishwasher and once opened, if its like mine, there will be gunk on the float and in the box at the line where it fills with water. This gunk floats in there and prevents the float from swinging and activating the switch. Just clean that gunk out with a toothbrush, I end up doing mine about once every four months, and it should work fine again. This tech said to prevent this, make sure the water is hot at the beginning of the cycle and pre-rinse the dishes-but this doesn't seem to work with mine.
