Question and Answers

Q:

WM3431HW power issue WM3431HW Lg Washer

A:

Thank you for your question and I understand your concern.
 
Try leaving the washer unplugged for 2-3 minutes and the reconnect the power cord. If it does not power up, it could have a bad or loose wire connection, a faulty noise filter or a faulty main PCB control board.
 
I strongly suggest calling a service technician to properly diagnose and repair your LG washer.

Q:

LG WM3431HW: Cold water over-pumping question in the condensation dryer parts

A:

I recommend that you check the operation of that water level pressure switch using the diagnostic test that is shown in the first image. Make sure that the frequency is changing properly when the washer fills in the test mode. You can also check the other components in the unit using that test mode. You can unplug the unit and check the components in the dryer using the information in the second and third images. I don't recommend that you conduct any live voltage checks as shown in that third image. You should be able to check the resistance of the components using a volt/ohm meter to determine whether they are okay. Check the wire harness connections.

There are the preliminary checks that I recommend to properly diagnose and repair this dryer problem. Reply with details of the results of the checks and we will try to assist you further.

This can be a complicated machine to diagnose and repair. I understand that you were able to tear down the unit and replace that bearing. Diagnosing and repairing the failure that you are describing will normally require some detailed checks such as the ones described above. We will assist you as much as possible in trying to determine the cause of this failure. If you get to a point where you would rather have a service technician physically examine the unit and repair it, you can schedule service using this link: Sears Home Services .

I am glad to hear that you got an answer for your problem. Unplugging the wire on that cold water supply valve for that dryer will definitely prevent the water from running constantly in the drying cycle. If you replace that triple valve assembly and it fixes your problem, let me know. If the valve was defective and was allowing too much water to flow through the condensation chamber, then replacing that valve should fix your problem. I was not aware that you could have that type of failure in the dryer water valve. If you replace that valve and still have problems, you could have a sensor or control board issue that is causing the valve to be constantly energized. A problem with the duct assembly or the inlet water line/nozzle could cause too much water to enter the drying system. Let me know what happens when you replace that water valve.

Q:

outer rear tub replacement worth it??

A:

The diagnosis sounds reasonable based on your symptoms. I am not aware of refurbished models like that one being available. That type of machine is not a huge seller. The parts from LG are normally reasonable. The labor charge sounds normal. If the washer/dryer combo is over 5 years old, then I would probably consider replacing it instead of repairing it.

I hope that this information helps. If you need more assistance, let us know.
