Maytag MHW4100DW0 washer Parts

On the Maytag MHW4100DW0, you reset the door lock by canceling the cycle and power-cycling the washer; then restart a cycle so the control can re-run its door-lock self-test (you should hear the lock click and the drum make a partial turn). See the MHW4100DW0 owner’s manual for the exact control steps.

Quick reset steps (safe and effective)

• Touch POWER/CANCEL once to stop the cycle and clear the display.
• Wait for the washer to stop; after a spin, this can take 20 to 30 minutes.
• Unplug the washer (or switch off the breaker) for 1 minute.
• Restore power.
• Close the door firmly and touch and hold START to begin a cycle; the washer will self-test the lock.

If the door still will not unlock or lock

These checks fix the most common “door won’t lock” situations on front-load Maytag washers:

• Make sure the door is fully closed and nothing is caught between the bellow and the glass.
• Remove a few items if the drum is tightly packed; an overfilled load can prevent proper latching.
• If an error code is showing, clear it with POWER/CANCEL, then reselect and restart.
• If you see a drain-related error (for example, the washer cannot drain), address draining first; a washer that cannot drain may keep the door locked.

What you see	What it usually means	What to do next
Door Locked light on	Door is locked during a cycle	Pause or cancel the cycle, then wait for unlock
F## E## code	System or component fault	Clear with POWER/CANCEL, restart, then service if it returns
F5 E2	Door not locking	Check door closure and latch area, then restart

Parts that commonly affect door locking

If the door won’t lock consistently, the lock assembly or related sealing parts are common suspects.

• Washer door lock WPW10443885
• Washer bellow W11106747

Why it matters

The MHW4100DW0 verifies the door lock before tumbling and adding water. If the lock cannot complete that self-test, the washer may stop, display an error, or keep the door locked until it is safe to open.

Most Maytag washers, including the Maytag MHW4100DW0, typically last 10 to 13 years with normal household use and basic maintenance. Keeping the washer level, avoiding overloads, and fixing small issues early helps you reach (and often exceed) that range; see the MHW4100DW0 owner’s manual.

What affects lifespan the most

A washer’s life is usually determined by vibration control, drainage performance, and how consistently it’s cleaned and maintained.

• Keep the washer properly leveled to reduce wear on shocks, bearings, and the tub
• Avoid overloading; heavy loads strain the drive system and suspension
• Use the right amount of HE detergent to prevent residue buildup
• Clean the door seal and leave the door ajar to reduce odor and mildew
• Address slow draining quickly (a struggling pump runs hotter and longer)

Model-specific notes for MHW4100DW0

This Maytag model includes warranty coverage that supports long-term ownership when maintained correctly.

Item	What it means for lifespan	What you can do
1-year limited warranty (parts and labor)	Early defects are typically covered	Keep proof of purchase and follow care instructions
2nd through 10th year limited warranty (drive motor stator/rotor and wash basket side walls; parts only)	Key components are supported longer	Reduce vibration and overload to protect motor and basket
Installation requirements	Poor installation shortens life	Follow the MHW4100DW0 installation guide for leveling and spacing

Quick “repair or replace” rule of thumb

When a Maytag washer is within the 10 to 13 year window, repairs are often worthwhile if the tub and motor are in good shape.

• Worth repairing: drain issues, door lock problems, minor leaks, vibration from worn shocks
• Consider replacing: repeated major failures, severe tub/bearing noise, multiple high-cost repairs close together
• Start with the basics: check leveling, load size, and drain performance before replacing parts

Why it matters

A front-load washer like the MHW4100DW0 can run for a decade or more, but vibration and moisture are the biggest lifespan killers. Correct installation, routine cleaning, and prompt repairs protect expensive assemblies like the tub and motor.

On the Maytag MHW4100DW0, the fastest way to force the washer to empty water and extract it from clothes is to select Drain & Spin. If it will not drain or reach spin, the most common causes are excess suds, an unbalanced load, or a drain hose or pump restriction.

Quick steps to drain and spin

• Make sure the door is fully closed and latching; the washer will not spin with a door issue.
• Select Drain & Spin (add Extra Rinse if you have oversudsing).
• Do not add detergent when running Drain & Spin.
• If the load is tightly packed or a single heavy item, redistribute and try again.
• If the washer was paused or canceled, allow time for it to stop spinning; it can take 20 to 30 minutes.

Check the most common “no drain / no spin” causes

1) Oversudsing (HE detergent issue)

Using non-HE detergent or too much detergent can slow or stop draining and spinning.

2) Drain hose installation

A drain hose that is kinked, clogged, or installed too high can prevent proper draining.

What to check	What “good” looks like
Standpipe height	End of drain hose is below 96 in. (2.4 m)
Air gap	Hose fits securely but is not sealed or taped airtight
Flow	No kinks, clogs, or crushed sections

3) Pump or filter restriction

Coins, socks, and other small items can block the drain path and keep the washer from draining fully. If you suspect a restriction, inspect the pump area and related drain components; the washer drain pump WPW10605427 and washer drain pump filter cap W11568579 are common service parts for drain issues.

Why it matters

Drain and spin problems leave clothes soaking wet and can trigger repeated cycle interruptions. Correcting detergent use, load balance, and drain setup prevents strain on the drain pump and helps the washer reach full spin speed.

For cycle and option details specific to this washer, follow the steps in the MHW4100DW0 owner's manual.

For the Maytag MHW4100DW0 washer, the most common problems we see are “won’t drain/spin,” “won’t fill,” and “door won’t lock.” These are often tied to drain restrictions, excess suds from non-HE detergent, water supply issues, or a door lock problem; the MHW4100DW0 owner’s manual troubleshooting section walks through the exact checks.

Most common symptoms and what usually causes them

• Washer not draining or clothes still wet: clogged drain path, drain hose installed incorrectly, or a failing pump
• Washer won’t run or fill: water supply turned off, kinked hoses, clogged inlet screens, or no power
• Door won’t lock: door not fully closed, latch/lock issue, or a related error condition
• Excess suds (“Sud”): too much detergent or non-HE detergent causing a suds reduction routine
• Vibration or “walking”: washer not level, feet not locked, load too large/unbalanced, or shipping bolts left installed

Quick checks we recommend first (fast, no parts)

1. Use HE detergent only and measure carefully (too much can slow or stop draining/spinning).
2. Confirm both hot and cold faucets are fully on and hoses are not kinked.
3. Check the drain hose setup: it should not be shoved too far into the standpipe (the manual calls out a 4.5 in max insertion).
4. Level the washer and lock the feet; uneven floors can cause vibration and noise.
5. If an error code is showing, match it to the symptom and correct the cause before restarting.

When a part is the likely fix

Symptom	Common part involved	Example part for MHW4100DW0
Won’t drain, drain error, water left in tub	Drain pump or pump filter cap	Washer drain pump WPW10605427, washer drain pump filter cap W11568579
Door won’t lock/start	Door lock	Washer door lock WPW10443885
Leaks at the door area	Door boot (bellow) or clamp	Washer bellow W11106747, washer door boot spring clamp W11218344

Why it matters

Drain, fill, and door-lock problems can stop the cycle completely, leave clothes soaking wet, or trigger repeated error codes. Fixing the root cause (hose setup, detergent, leveling, or a worn part) prevents repeat failures and protects the drive system.
