It's amazing we had still been able to wash clothes at all! With the help of the excellent... Read more

The upper counter-balance weight mount design is a poor design to begin with. It started to rattle loose approximately 5yrs into the 8yrs that we've owned it. As it would start to loosen up (as evidenced by the loud banging noise exhibited during operation); I'd shut it down, pull the top off, remove the weight (it was almost always half rattled off at this point), wrap the mount lugs with friction tape (the plastic lugs were being worn down/chaffed by the balance weight), put the weight back...

Vent Hose
Genuine Lg part
By: Lg
Part Number: 4738ER2002A

The Vent Hose is an OEM part for LG washing machines. This hose is essential for ensuring proper ventilation within the washer, allowing air to circulate and preventing the buildup of moisture and mildew. It helps maintain the efficiency of the washing machine by facilitating the expulsion of air and excess water vapor during operation.

Causes of a bad washer vent hose can include wear and tear over time, blockages from lint or debris, or damage due to bending or pinching.

Symptoms of a bad vent hose include:

  • Excessive moisture or condensation inside the washer
  • Musty odors from the washing machine
  • Visible cracks or holes in the hose
  • Poor ventilation leading to inefficient washing cycles

This OEM LG part is also compatible with Sears/Kenmore.

What's included: One tub-to-pump hose Install notes:
  • Unplug the washer and turn off water supply; drain any remaining water from the tub/hoses
  • Access location varies by model; remove panels as needed to reach the hose and clamps
  • Use pliers to release spring clamps; note routing and clamp orientation before removal

Do-It-Yourself Stories from Customers like You The washer appeared to be leaking   Michael M. • Newbury , MA • December 14, 2015

Based on info around the web and your site I chose to replace all of the bellowed hoses (3) in the machine, as I did not know which bellow was leaking without taking the washer apart first. If one hose was old enough to leak I figured the others were not far behind. The appliance parts pros videos were very helpful, although I chose to replace the drum drain bellows via access through the rear panel thereby saving myself the time of disassembling the front of the machine, as was instructed.

My son in law easily replaced the stator and the machine worked. I washed a couple of loads and it shock more than before. The next day I washed a load and it shook so much it took two of us to keep the machine from traveling across the room. So back to the drawing board. Read more

Rotor Position Sensor (Hall Sensor)
Genuine Lg part
By: Lg
Part Number: 6501KW2001A

This rotor position sensor (Hall sensor) tracks the direct-drive motor's rotor position and speed so the control can commutate the washer motor accurately. Replacing a failed sensor can restore proper wash/agitate and spin performance. What it does:

  • Detects rotor position and speed from the stator assembly
  • Sends timing feedback to the control for correct motor start, direction, and speed
  • Supports smooth agitation and spin ramp-up/ramp-down
  • Failure may cause: no spin or agitation, cycle stalling/pausing, or an LE motor error code
What's included:
  • 1 rotor position sensor assembly
Install notes:
  • Unplug the washer and shut off water; wear protective gloves
  • Access the motor at the rear of the tub; remove the back panel if needed
  • Remove the rotor and stator; support the stator to protect wiring, then unclip/unscrew and replace the sensor
  • Align the sensor correctly and seat the connector fully before reassembly and testing
