LG wash machine # wm 2277 hb front loader display flashes LE wont

We had the OE message come up and did the above procedures...that didn't fix it. I removed the dual pump modules (they come off in one piece...one is the recirculating pump, the other is the drain pump). Turns out, the drain pump impeller design sucks. Even though it turned when I put power to the pump, that doesn't mean your pump isn't bad. Once it is under load pumping water, the impeller can slip where the pin connects to it from the motor. We replaced the motor for $60 and that fixed the problem. Our unit is at least three years old and we have a family of four, so it does get used quite often. Nobody told us about the filter at the bottom of the unit and I figure if we knew this ahead of time, we probably could have avoided the impeller issue...but it is still a sub-par designed motor/impeller. The new one I ordered looks like an updated design so I don't see this happening again. It is quite easy to remove and replace the pump, btw.

It is a locked motor error. One of the following is causing the problem but you may need the help of a qualified appliance technician:

1. The connector (3-pin, male, white) in the motor harness is not connected to the connector (3-pin, female, white) of the stator assembly. Connect them properly.
   
2. The electrical contacts between the connectors (3-pin, male, white) in the motor harness and 4-pin, female, white connector in the main board assembly is bad or unstable. Clean the connectors and connect them properly.
   
3. The motor harness between the stator assembly and main board assembly is cut or open. Reconnect or rewire.
   
4. Motor winding is defective. Check the resistance between the terminals of the stator. Resistance should be between 5 to 10 ohms, else replace the stator with part number 1266809. Price ranges from $100 to $150.
   
5. The hall sensor is out of order/defective. It is located at the stator assembly. If the hall sensor is out of order, it cannot detect magnetic field and the main board sees it as the rotor is locked then displaying the error code. Replace it if no evidence of defect is found above. Part number is 1268238 at about $25.
