Drain Pump Can Stop Working After 4-6 years

Has your LG washing machine stopped draining as it should? If so, you could be looking at an issue with the drain pump.

Small objects or particles of clothing can sometimes get caught in the drain pump.

Sometimes you even can hear excessive noise coming from the drain pump. This first sign that the pump needs your attention.

To determine if the pump is blocked or malfunctioned, you’ll need to access it and see if there are any obstructions.

If you find items inside, remove them completely. If you don’t find any and the pump is either noisy or not turning on, you’ll need to replace the part.

Here’s how to locate and repair the drain pump:

  1. Disconnect the power to the washer
  2. Remove the two lower screws on the rear bracket that hold the top in position
  3. Pull the top back about an inch, lift straight up, and remove
  4. Take the soap drawer completely out
  5. Remove the screws that hold the soap housing in place
  6. Remove the screw on the right side of the control panel (if there is one)
  7. Remove the control panel by lifting it up and setting it on top of the machine
  8. Open the door on the bottom left corner of the washer, and set it aside
  9. Remove the drain hose and empty the water present. Set the hose aside
  10. Loosen the screw at the bottom of the drain clean out
  11. Remove the assembly
  12. Remove the final screw holding the front panel in place
  13. Open the washer door and remove the band clamp that holds the bellows in place
  14. Peel the boot away from the front panel and push into the washer opening
  15. Unplug the wiring harness from the bottom of the door lock assembly
  16. Close the door and remove the four screws across the top. Be sure to hold the front panel as you remove the last screw
  17. Remove the front panel and set aside
  18. Remove the hoses attached to the drain pump
  19. Loosen and remove the final screws on the front that hold the drain pump in place
  20. Lift the pump assembly out
  21. Disconnect the wiring harness and remember where the wires go
  22. Remove the screws that hold the pump motor to the pump body
  23. Take the cover off the existing motor
  24. Install the new pump motor and begin working backward to reassemble your machine

Motor Wire Harness Can Break

Another common issue with LG washing machines is you may notice weird noises during the spin cycle.

No in-home service calls. No appointments.

This can be caused by issues with the wiring harness that’s connected to the motor.

Wires commonly break off due to vibration and this disrupts communication between the control board and the motor.

If this occurs you will need to locate the motor inside the washer and visually inspect all the wires.

If you find that a wire is burnt or broken, simply replace the wiring harness or repair the wire that’s broken, if possible.

Position Sensor Wire Can Break

The position sensor is important for communication with the control board. Because it sending the exact position of the motor.

If the wire becomes detached or broken, it can cause your LG washer to stop functioning properly.

Again, you’ll need to locate the wiring to the position sensor and check it for damages.

If you find any damages it will require you changing the wiring harness, or simply repairing the wire that’s broken.

Here’s how to replace this wiring harness:

  1. Disconnect the power and shut off the water supply
  2. Remove the hot and cold water supply lines from the inlet valve. Water will spill out
  3. Carefully tip the machine back so it’s laying on the rear panel
  4. Unthread the mounting nut for the rotor
  5. Carefully remove the rotor assembly
  6. Use a socket to remove the mounting bolts from the stator
  7. Disconnect the wiring harness
  8. Install the new wiring harness the same way you removed it
  9. Reassemble your machine

Water Inlet Valve Can Be Stuck OPEN

LG washing machines will begin overfilling with water due to calcium build up in the solenoid valve and thus valve can be stuck in OPEN position.

This issue sometimes happens even when a washing machine is OFF

So, if you will see a lot of clear water in the drum on the next day after laundry, that’s a sign that something wrong with the inlet valve.

The first thing you will want to check is the inlet valve. These parts commonly fail, as they become stuck mechanically in an open position.

Here’s how to replace this part:

  1. Disconnect all power going to the washer
  2. Turn off the hot and cold water supply valves
  3. Remove the hoses from the inlet valve. Some water will spill out
  4. Remove the screws at the rear of the main top
  5. Slide the main top back about one inch, and lift up to remove
  6. Note the location of the solenoid wires to the old inlet valve and disconnect them
  7. Use pliers to remove the four hoses – remember where these go before pulling them off
  8. Remove teh mounting screws that hold the valve in place
  9. Pull the old valve out
  10. Install the new valve and move backward to reassemble your washer

Washer Inlet Valve Leaking Water on the Floor

Another common issue with the water inlet valve on an LG washing machine occurs when it begins leaking water on the floor.

This water may be coming from either the hot or cold inlet valve.

The water supply lines are under constant pressure, and when water solenoids worn out and not able to keep pressure, you will notice water leaking from them.

Before checking the water inlet valve, first make sure the hot and cold supply hoses are tightened securely. If you find they are loose, simply tighten and see if your problem is gone.

If you do this, and still see water leaking, follow the steps above to replace the water inlet valve because it’s probably faulty and stuck in an open position.

  1. I have an LG WM3997HWA/01 Washer dryer combo. LE code came up. It doesn’t have a positions sensor. The wires have continuity all the way up to the control board. It isn’t the stator or the rotor as they are both new.
    Any thoughts? Thanks

  2. I have lg washer top loader that I set on speed wash which normally take 35 minutes. recently I noticed my 35 minutes load has extended by 20 minutes. therefore, my speed wash load that was 35 minutes is now 55 minutes. Seems there is an additional cycle added somehow. I have reset the settings and disconnected washer to see if it would change but its the same.
    does anyone know if this can be corrected ?

  3. I have a LG washing machine Model WM3470H, aprox. 5 years old that has water coming out of the air vent inlet beneath the water hose inlets and runs onto the floor. Could this be cause by malfunctioning solenoids on the water inlet valves?

  4. My LG inverted drive front loader fills with water, makes noise in wash cycle (wash cycle blinking) and will not start to agitate. Stays on wash cycle. I have not gotten any error code yet.

  5. We have a top loader Lg model wt1101cw everything haas been great with performance. The issue we have had in 2018 and the exact same in 2022 the lid latch on the right side cracked than before we are aware of this the broken box containing the latch components cracks the inside of the lid. ANYONE else experiencing this?

  6. I am using LG 6.5 kg inverter top loading machine from last 3 years but recently when water is pouring in the machine a small noise is coming. Please elaborate this problem. Is it any problem or its normal ?

  7. good day .I have an LG Front load inverter Direct drive wash. The water keeps fiiling and keeps washing the wash cycle does not changed.

  8. Hi, I have a problem with the washing machine whose water always comes out when the switch is turned on. Thank you.

  9. Hi
    We have a LG top loader washing machine …WTG 8520
    We can’t get the fabric softener to dispense. We have cleaned everything but the fabric softener holder generally won’t empty. What is the likely problem?

  10. Hi there the LG toploader drain valve motor moves in and out very quickly when in spin mode. Does not stop in one position. + The inside of drain motor looks worn out.

  11. Hi, I have an LG washer model number: WM3998HBA we purchased in August last year, one thing I have found some of my clothes don’t dry completely at times.I don’t overload the drum. Most times there are no problems. But when I did laundry this week and when it was finished there was water on the floor. Clothes were dry, but don’t know where the water came from, Could you tell me what causes thie.

  12. Recently someone was using my washer and when he turned it on there was like a rattling kind of noised coming from the washer. Never heard that before. I’m hoping it is nothing real major. I turned it off and haven’t used it since. Anyone out there familiar with this little problem?

  13. I have a new Inverter Direct Drive
    When i set the timer for “Normal wash” the clock shows 60 minutes. The washer spins and pre sets for water. After the water is added and agitating starts ,time involved less than 10 min.
    The timer jumps from 60 min. to 35 (lost 20 min. on the timer)
    IS IT normal?????

  14. Each time I press the start button of my LG F1022TD5 I have power failure. Any ideas what ti’s maybe causing it?

    • Hard to say.. this kind of issue needs to be troubleshoot by a professional.
      Sounds like the problem with the control board relay

  15. My Top load washer is only two years old, but it seems to only use hot water no matter what cycle is chosen. The hoses are not reversed, nor are they leaking.

  16. Dreaded OE code on LG front load model WM2501HWA. Machine goes through wash cycle and drains, but then stops and the OE code appears. If I then turn off the washer, and restart it on Rinse/Spin it completes the job and clothes come out fine.

    Drain hose is not clogged or crimped; drain pump filter has no clogging at all. Drain pump is working as it empties the drum of water.

    Any ideas of problem cause?

    Thank you.

  17. I have since discovered, if I shut off the cold water line to the washer and only leave the hot open it will fill with hot water. However, I have to set a timer to make sure I turn the cold back on for the rinse cycle.
    Just trying to determine if this is a “valve” issue on the back of the washer or a solenoid issue?

  18. My automatic front loader F12U2QNP7S is 3 years old…
    I had a few problems initially:
    1. It does release fabric softer
    2. Recently the door won’t close and there is a spring that came of from the door rubber.

  19. Additional info on 1/2/2022 post re: LG WM2501HWA Washer

    Question:
    Initially didn’t load with water when I try & wash – is is also caused by the drain pump? Is there any other way to test what additional might be wrong? Can I run the washer on a specific cycle without anything in it – for additional testing and verification?

    UPDATE:
    Had let washer sit for 2+ days and tried washing a full load of clothes on 1/8, on bulky/large. This time: Water and soap loaded, drum turned & determined size and washed the load. HOWEVER, when it got to the rinse then spin, it never did either. So I drained & cleaned the pump filter, numerous times, [only miniscule particles found], & removed wet clothes.
    Tried rinse & spin again a couple of times, & drained lower pump filter but nothing.
    Finally, found Tub Clean & it adds water, spins & washes tub with no problem, BUT, it stopped probably midway thru.
    Removed remaining water after washing stopped.
    Checked pump filter & drain – no particles found.
    What next to try – if any. The drain pump “appears” to need to be replaced. Anything else?

  20. Hi, there. Inherited an LG WT5001CW washer.. must be 8 or 9 years old. Has been working great the last few months, but one day recently the hot water isn’t going into the machine when I select ‘warm’ or ‘hot’ temperature. It has been working great up until this point.
    Thank you!

      • I am having the same problem. I’ve checked to insure correct water lines, valves are on, hose is warm, ran a sink near by to fill the lines prior but the water only fills will ice cold water. I’ve even tried different cycles, but again only cold water.

      • I have the same washing machine and the same hot water problem. Has anybody figured out what the problem is and how to fix it?
