I have a LG washer, WM3170CW. C comes up after I close the door. Because of that I can't set a wash speed , therefore it doesn't work. I have tried unplugging it but that did not work.

call a local repair service if it is old then plan to replace it

Most likely door latch / lock needs replacing

You don't need to order anything. The manual is available for (free) download at http://www.lg.com/us/support-product/lg-WM3170CW#manuals

IT CANT HOLD TO MUCH

The LE code indicates a motor overload. The washer will not spin to avoid damaging the unit. First unplug the washer and let the motor cool for 30 minutes. When you plug in the washer, check if the unit has been reset.

The error often occurs if you use a non-HE detergent or too much detergent. In that case, do a Rinse and drain steps. Set the Spin Speed to No Spin by pressing that key several times. When that finishes, open the door and remove all of the clothes in the tub. Close the door and set the washer to Rinse and Spin. Run this program several times until you see no suds in the wash tub. If the LE code returns when the washer is empty, check the drain pump and filter for foreign objects. The error can also occur if you wash too many items at once or too heavy a set of items. Try doing a smaller load in the future.

If the error persists, then the tub motor, bearings, motor shaft or wiring may be damaged. Here is the parts diagram and one vendor's list of the replacement parts: http://www.searspartsdirect.com/lg-washer-parts/model-WM1814CW/3204/0153200/K0810333/00002.html . If your washer is under warranty, contact LG.

I hope this helps.

How many years is yoru washing machine? I suspect bthe magnet on the lid of the washer has probabkly come off which causes the washer not to identify that the door is closed. U need to replace a magnet on the lid.

LG WFT70A37ECT Top load washing machine, showing DE error... even door is close still showing this error. that is the solution... really appriciate... thanx

The door switch may be malfunctioning so it is not making good contact and therefore not sending the message that the door is closed.
