Error Codes for Whirlpool WTW4855#

The Whirlpool WTW4855 series uses LED indicator lights or beep patterns to signal faults rather than alphanumeric codes. If any indicator light is flashing or the unit beeps continuously, try a power reset first: unplug the unit (or flip the circuit breaker) for 60 seconds, then restore power. Many transient errors clear with a simple reset. If the behavior returns, the underlying issue requires professional diagnosis.

Recall Status#

There are no active recalls on the Whirlpool WTW4855 series as of 2026-05-28. We recommend checking the Consumer Product Safety Commission at cpsc.gov periodically with your specific model number, as recalls can be issued at any time. You can also sign up for email alerts on the CPSC website to be notified if a recall is issued for your appliance.

Repair vs. Replace: When Is It Worth Fixing Your Whirlpool WTW4855?#

This is the most common question we hear from Whirlpool WTW4855 owners. The answer depends on three factors: the age of the unit, the cost of the repair, and the cumulative repair history.

General rule for the Whirlpool WTW4855: If the unit is under 10 years old and the repair costs less than 50% of a new equivalent model, repair is almost always the better value. After 10 years, evaluate the total repair history — if cumulative repairs over the past 2-3 years exceed 40% of replacement cost, upgrading to a new unit provides better long-term value and a fresh warranty.

Before You Call for Service#

Before calling for service, verify the lid is fully closing (listen for the click), check that the water hoses are not kinked, and confirm the unit is level. For a washer that will not drain, check for coins or small items in the drain pump filter. Try a manual reset — unplug the washer for 60 seconds, then plug it back in and lift/lower the lid six times within 12 seconds to reset the motor.

What Are the Best Long-Term Ownership Tips?#

To extend the life of your top-load washer, do not overload — the agitator needs room to move clothes through the water. Use the correct amount of detergent (HE if specified). Check pockets before every load — coins and small objects are the leading cause of drain pump failure. Distribute heavy items evenly around the basket before starting the spin cycle to prevent excessive vibration and bearing damage.

Frequently Asked Questions#

How do I replace the agitator dogs on my Whirlpool WTW4855?#

Remove the fabric softener dispenser cap, then pull the agitator straight up. On the underside, you will see a cam assembly with 4 small directional dogs (ratchet teeth). Pry them out and snap in new ones — part 80040, affordable a set. The entire job takes 10 minutes with no tools. This is the cheapest and easiest washer repair — if your agitator wobbles or spins freely in both directions, this is the fix.

Why does my Whirlpool WTW4855 fill with water but not agitate?#

If the tub fills but the agitator does not move, the most likely cause is a failed agitator coupling or stripped agitator dogs. Less commonly, the motor coupling (between motor and transmission) has broken. The motor coupling is a three-piece plastic and rubber connector that absorbs shock — when it breaks, the motor runs but nothing moves. Part 285753A, takes 30 minutes to replace.

How long does a Whirlpool WTW4855 typically last?#

The WTW4855 is a traditional agitator top-loader, which is among the most reliable washer designs. With proper maintenance, expect 12-16 years. The simplicity of the design (fewer electronic components than front-loaders) means fewer things to fail. The most expensive repair is the transmission, but this rarely fails before 10 years.
