In this case, you need to drain water and remove the laundry. Then, run the rinse mode to clean the drum. Next, start the technique to make sure that the OC error has disappeared. If the washing machine is not correctly connected to the drain hose, OE, OF, E3 will appear on display.

Thank you for your post, friend!

I understand that your Electrolux washer is displaying an "E3" error code while it is spinning. However, it appears "E3" is an invalid error code. It is possible that the error code is missing characters? I suggest resetting your washer. You can do this by flipping the household circuit breaker for roughly ten minutes. If resetting the power does not correct the issue, and your washer continues to display "E3" I would recommend contacting a professional to come and properly diagnose your appliance. -Matt

micheline, according to the LG Owner's Manual for the Model Number you listed, there is no LED display on the casement window unit (please see the Owner's Manual link below). How are you getting an E3 error code? Or by chance, did you list the wrong model number? Even Goldstar, that is made by LG, doesn't show your model number.

Please advise. Thanks.

if split ac display shows e3 what is the solution for that problem

No speed/RPM reading, Console displays "E3" error code
Check data cable integrity All wires in cable should be intact. If any are cut or crimped, replace cable.
Check data cable connections/orientation, insure cable is connected securely and oriented properly. Small latch on connector should line up and snap into place.
Check magnet position (requires shroud removal) Magnet should be in place on flywheel. If no magnet is present, replace the flywheel or the entire base unit (if unable to replace flywheel).
Check RPM Sensor (requires shroud removal) RPM sensor should be aligned with magnet and connected to data cable. Realign sensor if necessary ( 1/8" clearance between sensor and flywheel) if still error 3 then check the sensor with a multi meter unplug sensor leads attach meter to sensor connectors. Have someone by hand rotate the pedal while you observe the multi meter opening and closing the internal sensor circuit if no change in meter readings then replace the sensor.
