Whirlpool WTW5100HW3 laundry, residential, washer Parts

Whirlpool washer parts are only interchangeable when the replacement part is listed as compatible with your exact washer model, such as Whirlpool WTW5100HW3. Even within Whirlpool, similar-looking parts can have different connectors, sizes, or calibrations, so matching by model and part ID prevents fit and performance problems.

What “interchangeable” really means for WTW5100HW3

Parts interchangeability is about verified compatibility, not brand name alone. Whirlpool often uses multiple versions of the same type of component across different platforms.

Common examples where “close” is not close enough:

• A lid lock that mounts similarly but has a different harness plug or lock logic
• A drive belt with a slightly different length or rib profile
• A shift actuator with different timing or connector indexing
• A drain pump with a different outlet angle or electrical rating

How we recommend you match parts (fast and accurate)

Use your model number and the exact part ID from the parts list for WTW5100HW3.

• Match the full model number: WTW5100HW3
• Match the part ID (not just a description)
• Compare mounting points and wire connectors before installing
• Replace related wear items together when appropriate (belt and pulley)
• If the washer shows an error, use an error-code guide to narrow the failed system first

Quick compatibility examples for this model

Washer system	Example part for WTW5100HW3	What it affects
Lid locking	Lid lock-sol W11700916	Won’t start, won’t spin, lid won’t lock
Drive system	Washer drive belt WPW10006384	Agitation/spin performance, squeal/slip
Shifting	Actuator, shift W11481722	Mode changes between agitate and spin

Why it matters

Using a non-matching part can cause repeat failures, new error codes, leaks, or no-spin conditions. Correct-fit Whirlpool parts protect the control system, reduce vibration, and restore proper wash and spin performance.

On a Whirlpool washer like model WTW5100HW3, an F1 E3-style code commonly points to a drain or water-level sensing problem; the washer is not draining as expected or the control is seeing an abnormal water-level signal. We focus first on the drain path, pump, and pressure hose.

What to check first (fast, no parts)

• Unplug the washer for 1 minute, then restore power and try Drain/Spin.
• Make sure the drain hose is not kinked, crushed, or shoved too far into the standpipe.
• Check the standpipe or laundry tub for a slow household drain (backups can trigger drain errors).
• Reduce load size and redistribute; heavy, waterlogged loads can slow draining.
• Listen for the drain pump: a steady hum with little or no water flow usually means a restriction or failing pump.

Likely causes and the parts that match them

If the washer will not drain, drains slowly, or leaves water in the tub, these model-matched parts are the most relevant:

Symptom you see	Most likely area	Model-matched part to consider
Won’t drain, humming pump	Drain pump jammed or failing	Pump assembly, drain W11399437
Intermittent drain, odd water-level behavior	Pressure hose issue (loose, pinched, leaking)	Hose WP353244
Won’t start spin, lid won’t lock	Lid lock not engaging	Lid lock-sol W11700916

Why it matters

When the washer cannot confirm the tub is empty (or it reads an incorrect water level), it will often stop the cycle to prevent overflow, protect the drive system, and avoid spinning with water still in the tub.

When replacement is the right next step

Replace the drain pump when you have verified the drain hose and household drain are clear, but the washer still drains slowly, leaves water behind, or the pump only hums. For water-level related behavior, inspect the pressure hose routing and connections; replace it if it is brittle, split, or loose.

The most common Whirlpool washer problem is a no-drain or no-spin condition. On the Whirlpool WTW5100HW3, this is usually caused by a drain restriction, a failing drain pump, or a lid lock issue that prevents the washer from entering spin.

Quick checks we recommend first

• Make sure the load is balanced; redistribute bulky items and restart the cycle.
• Confirm the drain hose is not kinked, crushed, or shoved too far down the standpipe.
• Run a Drain/Spin cycle with the tub empty to see if it drains consistently.
• Listen for the drain pump; a steady hum with little or no water movement points to a clog or weak pump.
• If the lid will not lock, the washer often will not spin for safety.

Most common causes and the parts that fix them

If basic checks do not solve it, these are the most frequent repair paths on top-load Whirlpool washers like the WTW5100HW3:

Symptom	Most likely cause	Common fix
Won’t drain, water left in tub	Clog in drain path or weak pump	Inspect hose and replace pump assembly, drain W11399437 if needed
Won’t spin, lid won’t lock	Lid lock not engaging	Replace lid lock-sol W11700916 and verify strike alignment
Agitates but struggles to spin, burning rubber smell	Belt slipping or worn	Replace washer drive belt WPW10006384
Loud squeal or grinding during spin	Pulley wear or damage	Replace Whirlpool washer drive pulley W10721967

Why it matters

A washer that cannot drain or lock the lid will often stop before high-speed spin. Fixing the drain path or lid lock early prevents repeated cycle failures, reduces standing water odors, and helps protect the drive system (belt, pulley, and motor) from extra strain.
