Code "LE" When I power on, the machine starts to fill and then stops and shows a code of "LE" in the display screen.

error is too big of load possible motor draw too much or bad bearings

According to the service manual,

Daewoo Washing Machine Error Fault Code = LE
Fault Detected: Washing Machine Door Open
Washer Has Detected: Washing machine detected door as open or not locked
Check / Repair / Fix = Close door – Door lock switch – Door latch – PCB

f20 code you have problem with inlet valve check screen in the valve maker sure they not clog with dirt

The manual says LE code means your washer has tried to fill but has not reached the proper water level.

Please try the plain VINEGAR in the bottom of your dishwasher. It cleans out the pipes. When you start the machine it automatically starts to drain whatever water has been left from previous cycle. When this cannot happen, due to blocked outlet pipe, it will not precede with the wash cycle. Adding the vinegar, leaving it a few hours, or overnight (hey, I left it for a week one of those times!), it is enough to liquify any heavy fats in that pipe...enough to start the cycle and the normal draining gets reinstated.Hope this helps you, it is such a pain to go & choose another dishwasher to fit into the space allowed & that has all the functions you need. This 'fix' cures all my dishwasher blues! Havagreatday!

The LE code is displayed when the motor goes into an overload situation, if you have changed the Hall sensor and rotor, the only other problem is the stator overheating which will bring on the LE display.
Check the stator assembly, replace is faulty.

Hello,http://136.166.4.200/contents/Laundry/WM2277/WM2277xx_Service_Manual.pdf page 18 of this service manual elaborates on the LE error code and what to check.. Hope this helps you..
Thanks

If water runs in when the machine is OFF but stops when the tap is turned off it means a faulty watervalve.replace water valve. Probably a double valve. Dont mix up the hoses or the wires........Nomess

LE error will get displayed when the Lid is opened. Close the Lid and this will get resolved. Similarly you will get FE when the water is not flowing properly into the Machine its a Fill Error.

"LE" error means the motor has overloaded. There is no way to fix this yourself. You will probably need a new motor. Call for an engineer.
