Whirlpool WFW8740DW0 washer Parts

A 4.5 cu. ft. washer is typically considered medium capacity, and it handles most everyday family loads well. For Whirlpool front-load washers like WFW8740DW0, “large capacity” usually starts just above 4.5 cu. ft., but real-world capacity depends on how freely items can tumble.

What 4.5 cu. ft. means in real use

Instead of focusing only on cubic feet, we recommend loading by drum fill so clothes can move and rinse properly. Whirlpool’s guidance in the WFW8740DW0 owner’s manual is:

• Small load: about 1/4 full
• Medium load: about 1/2 full
• Large load: about 3/4 full
• Extra-large load: full, but items must tumble freely (do not pack tightly)

Quick capacity guide

Capacity (cu. ft.)	Common label	Best for
3.5 to 4.4	Small to medium	Singles, couples, light weekly laundry
4.5	Medium	Most families, mixed loads, towels
4.6 to 5.0	Large	Bigger households, bulky items more often
5.1+	Extra-large	Frequent comforters, large loads regularly

Why it matters

If you treat 4.5 cu. ft. as “extra-large” and overfill the drum, you can get poorer cleaning, more vibration, and longer dry times because items do not tumble and rinse efficiently.

Helpful tips to get the most from your capacity

• Wash bulky items (comforters, jackets) one at a time when possible
• Keep the top of the load below the door opening so the drum can tumble
• Use HE detergent and measure carefully to reduce residue
• Run the washer’s cleaning cycle regularly to control odor buildup
• Confirm cycle and option limits for your model in the WFW8740DW0 owner’s manual

Yes. On the Whirlpool WFW8740DW0 washer, the most reliable “reset” is a power reset and a control reset using the POWER button; this clears many temporary faults so you can reselect and restart a cycle.

Quick reset options (WFW8740DW0)

• Control reset (most common): Touch POWER once to clear the display or error code, then touch POWER again to restart and reselect your cycle.
• Power reset: Unplug the washer (or switch off the breaker) for 1 minute, then restore power.
• Cycle restart: After clearing the code, reselect the cycle and touch and hold START.

What to do if an error code is showing

Many Whirlpool Duet-style front-load washers clear certain codes by powering off the control.

What you see	What it usually means	What we do first
“Sud”	Excess suds routine is running	Let it finish; use only HE detergent and reduce amount
F8 E1	Water supply issue	Verify both faucets on; check inlet hose kinks and inlet screens
F9 E1	Drain issue	Check drain hose install and standpipe depth; inspect for clogs
“rL” / “Int” (interrupted)	Cycle paused/canceled; may still be draining	Wait for stop, then touch POWER to clear and restart

For code meanings and next steps, use our Whirlpool duet he front load washer error codes.

Steps that prevent the code from coming right back

• Use HE detergent only; too much detergent can cause “Sud” and slow draining.
• Confirm hot and cold hoses are connected and both faucets are fully open.
• Check inlet valve screens for debris if filling is slow.
• Make sure the door closes and latches fully before touching START.
• Verify the drain hose does not push too far into the standpipe (a common drain setup problem).

When a “reset” points to a part problem

If the washer repeatedly won’t drain or ends with wet loads after resets, the drain system is the first place we check. A common repair is replacing the washer drain pump WPW10605427.

Why it matters

Resetting clears temporary control logic and lets you restart safely, but repeated error codes usually mean a real issue (suds, water supply, or draining) that needs correction to prevent cycle stops and wet laundry.

For model-specific button sequences, diagnostics, and troubleshooting, follow the WFW8740DW0 owner's manual.

Yes. The Whirlpool WFW8740DW0 front load washer has routine cleaning you should do, especially the door seal area and monthly maintenance cycle, to prevent odors and residue buildup. For many Whirlpool front-load designs, a drain pump cleanout is also used to clear debris that can affect draining.

What to clean on the WFW8740DW0 (regular maintenance)

• Door seal (bellow): wipe residue and check for trapped items around the seal folds.
• Glass window underside: clean film that can cause odors.
• Monthly maintenance cycle: run the washer’s cleaning cycle at least monthly (or every 30 cycles).
• Detergent use: use only HE detergent and measure correctly to reduce buildup.

For the exact maintenance steps and cycle selection for this model, follow the WFW8740DW0 owner's manual.

Where the “filter” usually is on Whirlpool front-load washers

Many Whirlpool front-load washers use a drain pump cleanout (often behind a small lower access panel). Cleaning it helps when the washer:

• will not drain
• leaves loads wet
• stops mid-cycle
• shows drain-related symptoms

Quick comparison: door seal cleaning vs drain pump cleanout

Item	What it prevents	Typical signs it needs attention
Door seal (bellow)	Odors, mildew, residue	Smell, visible grime, water droplets trapped in folds
Drain pump cleanout	Drain problems, slow draining	Standing water, long drain time, wet loads

If you suspect a clogged drain system

If your WFW8740DW0 is not draining or is leaving clothes wet, debris may be restricting the drain path. A failing pump can also cause similar symptoms. The model-specific replacement pump is the washer drain pump WPW10605427.

Why it matters

Keeping the washer clean reduces odor-causing residue and helps the washer drain and spin correctly. It also helps prevent suds and buildup issues caused by using too much detergent or non-HE detergent.

The most common Whirlpool washer problems are draining/spinning issues, water fill problems, and excess suds, and those are also the top trouble areas we see for the Whirlpool WFW8740DW0. In many cases, the root cause is a simple setup, detergent, or hose issue rather than a major failure.

Most common issues (and what to check first)

• Washer not draining or leaving clothes wet: check the drain hose installation and look for clogs.
• Washer will not fill or stops mid-cycle: confirm both faucets are fully on and inlet hoses are not kinked.
• "Sud" (excess suds): use only HE detergent and measure carefully.
• Vibration, rocking, or "walking": level the washer and confirm feet are locked.
• Door will not lock or unlock: verify the door is fully closed and nothing is caught in the bellow.

Quick troubleshooting for WFW8740DW0

Start with these steps from the WFW8740DW0 owner's manual:

1. Suds and slow draining

   • Use only HE detergent.
   • Reduce the amount; too much detergent can slow or stop draining/spinning.

2. Water supply errors or no fill

   • Make sure both hot and cold hoses are connected and flowing.
   • Clean inlet valve screens and straighten any hose kinks.

3. Drain hose setup

   • Keep the drain hose from pushing too far into the standpipe (a common cause of drain errors and siphoning).

Common symptoms and likely causes

Symptom	Most likely cause	First action
Clothes still wet	Drain restriction or excess suds	Run Drain & Spin; reduce detergent
Won’t fill	Water supply issue	Turn on both faucets; check screens
“Sud” code	Too much detergent or non-HE detergent	Switch to HE; measure correctly
Walking/vibration	Not level or feet not locked	Level and lock feet

Parts that often relate to these problems

If the checks above do not fix the issue, these model-matched parts are commonly involved:

• Washer drain pump WPW10605427 (drain/no-drain, wet loads)
• Washer water inlet valve WPW10435242 (no fill, fill errors)
• Washer door lock WPW10443885 (won’t start, door won’t lock)
• Washer bellow W11106747 (leaks at the door, door sealing issues)

Why it matters

Front-load HE washers like the Whirlpool WFW8740DW0 use lower water levels and rely on correct detergent and hose setup. When detergent, leveling, or drain hose installation is off, you can get error codes, wet loads, odors, and repeat service issues.
