The OE error code on a LG dishwasher can mean several things. Here is a quick reference guide.
-Is the drain hose kinked or blocked?
-Wiring connection on pump OK?
-Drain outlet in sump blocked
-Drain pump motor circuit shorted. (Check Wires inside door)
The drain motor should read between 20 and 40 ohms. If the pump is clear from debris, replace the drain motor.
You can enter your LG dishwasher model number into the search box to order the motor.
