LG WM2455HW washer Parts

The LG WM2455HW washer has a wash capacity of 3.47 cu. ft. (IEC equivalent: 4.0 cu. ft.). This capacity helps you size loads correctly so the washer can tumble freely, rinse well, and reach full spin speed.

Capacity details for LG WM2455HW

Here is how the capacity is listed in the specifications:

Spec type	Capacity
Wash capacity (rated)	3.47 cu. ft.
IEC equivalent	4.0 cu. ft.

For the exact wording and the rest of the model specifications, check the WM2455HW owner's manual.

How to use capacity to avoid performance problems

Even with a large-capacity front-load washer, overloading is the most common reason for poor cleaning and spin issues. We recommend:

• Fill the drum loosely; items should tumble, not pack tightly
• Leave some space at the top of the load (do not compress laundry)
• Wash bulky items (blankets, comforters) in smaller loads
• Balance mixed loads (combine large and small items)
• Use only HE (high-efficiency) detergent and measure carefully

Why it matters

When the load matches the WM2455HW capacity, the washer can lift and drop items properly for cleaning, drain efficiently, and ramp up to high spin speeds. Overloading can lead to longer cycle times, excess suds, and out-of-balance spinning.

To reset an LG WM2455HW washer, we turn the washer off, wait about 1 minute, then turn it back on and reselect the cycle. If you press Power during a running cycle, it cancels the cycle and clears the current settings.

Quick reset steps (WM2455HW)

• Press Power to turn the washer OFF.
• Wait 60 seconds.
• Press Power to turn the washer ON.
• Turn the cycle selector knob to choose a cycle.
• Press Start/Pause to start.

If the washer will not start after a reset

These checks solve most “won’t start” complaints on this LG front-load washer:

• Make sure the door is fully closed and the Door lock indicator comes on.
• Press Start/Pause after selecting a cycle (the washer can turn off automatically if Start/Pause is not pressed within a few minutes).
• Confirm the outlet is a grounded 120 VAC, 60 Hz supply and the breaker is not tripped.
• Verify both water taps are fully open and hoses are not kinked.
• Clean the inlet screen filters if filling is slow.

What “reset” does (and does not) do

Action	What it affects	What it does not fix
Powering OFF then ON	Clears the current cycle selection and restarts the control logic	Clogged drain filter, failed door lock, failed pump, water supply problems
Canceling a cycle with Power	Stops the cycle immediately and loses current settings	Water left in the tub (you may need a drain/spin)

Why it matters

A reset is the fastest way to clear a canceled cycle or a control “glitch,” but repeated no-start, no-fill, or no-drain symptoms usually point to a door lock, water inlet, or drain issue that needs troubleshooting.

For control panel details and operating notes, use the WM2455HW owner's manual.

On the LG WM2455HW washer, the most common customer-reported issue is a drain or spin problem, often caused by restricted water flow through the drain system (such as debris in the pump filter) or an out-of-balance load that prevents proper spinning. See the WM2455HW owner's manual for the model’s troubleshooting checks.

Quick checks we recommend first

• Unplug the washer for safety before inspecting anything.
• Check the drain pump filter area for coins, lint, or small items that can block draining.
• Redistribute the load; heavy items can clump and trigger vibration or poor spin.
• Verify the washer is level and all leveling feet are firmly on the floor.
• Confirm you are using the correct amount of HE detergent to avoid excessive sudsing.

What symptoms usually point to a drain-side restriction

Symptom	What it often means	What to do next
Humming or gurgling near the end of the cycle	Drain pump is running but flow is restricted	Clean the pump filter and check the tub-to-pump hose
Water left in the drum	Washer cannot evacuate water fast enough	Inspect for debris in the pump and hoses
Rattling/clanking during drain	Foreign objects in drum or pump	Remove items and recheck draining

If you find the pump is damaged or seized, the correct replacement for this model is the washer drain pump assembly 4681EA2001T.

Why it matters

A washer that cannot drain normally often will not spin normally. Fixing the drain restriction first prevents repeat errors, reduces vibration, and helps protect components like the door lock and motor.

On the LG WM2455HW washer, diagnostics are handled through the control panel and the washer’s built-in error-monitoring system. For the exact button sequence and what each display or beep means, follow the steps in the WM2455HW owner’s manual.

What you can do right now (quick checks)

Before running any test mode, we recommend doing these basics because they often reveal the same issues diagnostics would flag:

• Unplug the washer (or switch off the breaker) for 1 minute, then restore power.
• Confirm the door closes firmly and the latch engages (a click is normal).
• Verify both water taps are fully open and hoses are not kinked.
• If filling is slow, clean the inlet screens at the back of the washer.
• If draining is slow or noisy, check the drain path and pump filter area.

Using built-in checks that act like diagnostics

Even without a dedicated “diagnostic cycle” button, WM2455HW has built-in behaviors you can use to confirm key systems.

Spin and balance check

The manual recommends a simple stability test that helps diagnose vibration, leveling, and out-of-balance issues:

• Place about 6 pounds of laundry in the drum.
• Press POWER.
• Select RINSE+SPIN.
• Press START/PAUSE.
• Watch for rocking or excessive shaking during spin; adjust leveling feet and retest.

For leveling details, use the WM2455HW owner’s manual.

If you see an error code

LG washers use error codes as the primary diagnostic output. Use our model-matched guide to interpret the code and the most common fixes: LG front load washer error codes.

Symptom or code type	Most common cause	Common next step
Won’t drain / drain-related code	Clogged filter, restricted hose, failing pump	Inspect drain path; consider washer drain pump assembly 4681EA2001T
Won’t fill / fill-related code	Closed tap, clogged inlet screens, valve issue	Clean inlet screens; consider LG washer single-solenoid water inlet valve 5220FR2006H
Door won’t lock / door error	Latch/lock problem	Inspect latch area; consider washer door lock switch EBF49827801

Why it matters

Running the right checks first prevents unnecessary part replacement and helps you pinpoint whether the issue is water supply, draining, door locking, or vibration and leveling.
