I own a Samsung Dishwasher DMR77LHS. I get an SE (drainage) error code right after the Wash cycle. I checked all of my drain lines and no problems. I even hooked up directly to my garbage disposal. And yes the plug has been removed. During the wash cycle the machine appears to be working fine, right after the wash cycle ends the machine drains very slowly and the SE error code comes on and the dishwasher stops running altogether. I'm wondering because of the slow drainage that the computer times out? Maybe a new circuit board is the answer, maybe a new pump. But. How much $$$ do you spend on a poor product? Better to go with a proven winner. Any suggestions?

SOURCE: How to knock out garbage disposal plug

Turn off the power source to the garbage disposal. Take the drain hose from the dishwasher off the connector going to the disposal (if connected). Insert a flat blade screwdriver in the drain hose fitting and tap a few times with a hammer. The plastic plug will pop off inside the garbage disposal. Reach inside from the top of the disposal to retrieve the plastic plug. Sometimes you have to use a little force to tap the plug out. Hope this helps you.

There should be an overload button somewhere on the bottom of the disposal motor. This is to prevent the motor from trying to run if the chopping blades are jammed, otherwise the motor would burn up.

First, try to move the blades with something like a broom handle. Using a flashlight you should be able to see the blades. there's probably three of them. try to make sure each one can move even a little bit.

Next, with the disposal switch in the off position, find the overload button and push it in, Then turn on the disposal switch and see if it runs. If the overload button trips off again, repeat the above steps until the blades can turn.

Let me know how this goes. Loringh

I have the same problem with my dmr77. My coffee pot ran over and evidently ran down behind the Samsung dishwasher. It thinks that it is leaking. How do you reset it?
