LG WM2450HRA OE Error Code Will Not Clear
« on: April 20, 2017, 04:24:10 PM »
I know what the OE error code means and typical causes.

1) NONE of the hoses are blocked and I have verified this with a garden hose. There are no kinks or leaks.
2) I have a new pump housing and new pump installed. I have double-checked to make certain the polarity of the wiring is correct.
3) I can't locate anything in between the tubs that could be blocking the drain hose. I have run water into the wash tub with the drain hose disconnected and the water drains freely from the tub.
4) The machine is level. 

So I reassemble the machine, reset it, start a rinse & spin cycle, and the OE error code pops up again.

Is this a control board issue? What else could it be?

drain it into a bucket rather than your house drain and see if it still throws the code

I don't understand what I have to gain by draining it into a bucket. Please explain. I'm losing my n patience with this thing.

I'm assuming that the washer is pumping water out at a decent rate, (draining it into a bucket allows you to verify this) it just throws the OE error after it begins draining.  If there are no clogs or restrictions and you have installed a new pump, I would suggest you look for crud in the stub going to the pressure switch hose at the bottom of the tub or in the pressure hose. It could also be a bad pressure switch, but I don't ever recall seeing one fail on an LG. The pressure switch checks the water level in the washer and sends a signal to the control board, which reports the water level as a frequency. If you press and hold the Wash/Rinse button and the Delay Wash buttons together, you should see a water level frequency greater than 25 kHz on the display. If it's lower than that, you most likely have a problem with the pressure hose or pressure switch. It could also be a control board issue but check the other things first.
