LG WT4870CW washer Parts

The LG WT4870CW washer has a 4.5 cu. ft. capacity. For cycle-specific loading guidance (bulky items, bedding, and high-efficiency detergent amounts), we recommend following the load and care instructions in the WT4870CW manual.

What “4.5 cu. ft.” means for real-world loads

Capacity is the tub volume; it helps you estimate how much laundry the washer can handle without overfilling.

• Best cleaning happens when clothes can tumble and circulate freely
• Overloading can cause poor rinsing, out-of-balance spinning, and extra wear
• Underloading can lead to inefficient water and energy use

Quick loading guidelines (works well for most top-load washers)

Use these practical checks when loading your WT4870CW:

• Load loosely; do not pack items down
• Keep items below the top of the tub ring area
• Mix large and small items to help balance during spin
• For bulky items, wash 1 to 2 pieces at a time (depending on size)
• Use HE detergent and measure carefully to avoid oversudsing

Common load examples (approximate)

These examples help translate capacity into typical household loads.

Load type	Typical fit in a 4.5 cu. ft. top-load washer	Tip
Everyday mixed laundry	Medium to large load	Leave space at the top for movement
Towels	Several bath towels plus hand towels	Avoid washing only one heavy towel
Bedding	Many comforters fit, but thickness varies	Use “Bulky” cycle if available

Why it matters

Matching load size to the WT4870CW’s 4.5 cu. ft. capacity helps prevent vibration, improves cleaning and rinsing, and reduces strain on key components like the drive system and suspension.

Most LG top-load washers, including model WT4870CW, do not have a front-access drain pump filter like many front-load washers. Instead, draining clogs are usually handled by checking the drain hose, the pump inlet area, and the tub for small items; see the WT4870CW washer manual for model-specific care and cleaning guidance.

What WT4870CW typically has instead of a drain filter

On WT4870CW-STYLE top-load designs, the most common places debris causes “won’t drain” symptoms are in the drain path, not a clean-out filter door.

• Check the standpipe or laundry sink for slow draining
• Inspect the drain hose for kinks, crushing, or a clogged hose end
• Listen for the drain pump running during the drain portion of the cycle
• Look for small items (coins, socks) trapped between the inner basket and outer tub
• If the washer hums but does not drain, the pump may be obstructed or failing

Quick drain-path checklist (safe DIY)

1. Unplug the washer.
2. Confirm the drain hose is not pushed too far down the standpipe.
3. Remove the drain hose from the standpipe and check for blockage at the hose end.
4. If draining is still poor, the next step is typically inspecting the pump and hoses for obstructions.

If you determine the pump is not moving water (or is noisy/humming), the compatible replacement for this model is the kenmore elite washer drain pump 4681EA1007A.

Symptoms and likely causes

Symptom	Most likely cause	What to check first
Won’t drain at all	Blocked hose or failed pump	Drain hose routing and clogs
Drains slowly	Partial clog or restricted standpipe	Standpipe flow and hose end
Hums during drain	Pump jammed or failing	Pump inlet area and impeller
Drains but leaves water	Siphoning or installation issue	Hose depth in standpipe

Why it matters

A restricted drain path can trigger long cycle times, poor spin performance, and standing water that leads to odor. Keeping the drain hose routed correctly and clearing obstructions early helps protect the drain pump and prevents repeat clogs.

On the LG WT4870CW washer, TurboWash is designed to shorten the overall cycle time while still cleaning effectively by using more aggressive spray action and optimized wash motions; a normal wash typically relies on standard fill, agitation, and rinse steps and usually takes longer.

How TurboWash changes what the washer does

TurboWash is mainly about cleaning efficiency per minute. Instead of only depending on the tub filling and the washplate moving the load, the washer uses additional spray patterns and timing to speed up saturation and soil removal.

• Shortens cycle time compared with a comparable normal cycle
• Uses added spray action (water jets) to wet and flush fabrics faster
• Often changes the rhythm of agitation and pauses to improve turnover
• Can reduce “waiting” time during fill by cleaning while filling
• Works best with typical mixed loads, not extreme overloading

For cycle-by-cycle details and which cycles support TurboWash on this model, use the WT4870CW manual.

When to use TurboWash vs normal wash

TurboWash is a good default when you want faster results without stepping down to a “quick wash” style cycle. Normal wash is a solid choice when you want a more traditional, longer wash profile.

Choose this	Best for	What to expect
TurboWash	Everyday loads, time savings	Shorter cycle, more spray action
Normal wash	Heavier soil, when time is not a concern	Longer cycle, standard wash pattern

Tips that matter on this model

Even with TurboWash, load size and water level sensing still affect performance.

• Load loosely around the washplate; avoid packing items down
• Use HE detergent and measure carefully (too much can reduce rinsing)
• Select the right soil level; higher soil can extend time even in TurboWash
• If cleaning seems weak, inspect the washplate area for buildup or looseness

If you suspect poor agitation (clothes not moving, grinding, or slipping), the wash system parts to check first on WT4870CW include the washer washplate AGZ72909711.

Why it matters

Choosing TurboWash vs normal wash helps balance cleaning, fabric care, and time. If you are troubleshooting “not cleaning well,” knowing which cycle you used helps narrow whether it is a cycle-selection issue or a wash system (washplate/drive) issue.
