@lindav OE is a drain error displayed when the dishwasher is not fully drained out in spite of 5 min. drain operation.

* Caused for that can be :

* The Drain Hose kinked or blocked.

* Wiring connection is OK?

* The drain outlet of sump is blocked.

* The Drain Pump/Motor or circuit is No drainage though drain pump is working properly? Air in the impeller of the drain pump might cause this case.

  • The Air gap is clogged.

* Knockout plug of garbage disposal not removed.

To remedy these you want to :

Remove the cause of kink or block.

Check the wiring connection.

Measure the electric resistance of Drain Motor. (20-40 ohm )

Replace the Drain Motor or repair

Remove all the water remained in the drain hose that is connected to the drain pump / motor.

Keep the unit upright, don't lay it down. Cautious about leaking on the floor.

Clean the air gap.

Remove knock out plug.
