Whirlpool Washer Error Code FL

Whirlpool washer FL error code explained

The FL code on a Whirlpool washer indicates a flooding or leak detection condition. This error appears when water is detected in the base or when a sensor determines the tub is overflowing or filling incorrectly. It is a protective alert meant to prevent water damage to your home and to avoid electrical hazards. Users typically notice the washer stopping mid cycle, not completing wash or spin steps, water on the floor, or a persistent FL code that prevents normal operation. Impacts include potential flooring and subfloor damage, ruined laundry, longer downtime while troubleshooting, and safety risks such as electric shock or mold growth if water sits under the appliance.

Common causes

• Leaky water inlet hoses or loose hose clamps
• Faulty or stuck door boot seal (front-load models) or tub seal failures
• Malfunctioning drain pump or clogged drain line causing overflow
• Pressure switch or water level sensor failure, or blocked pressure hose
• Excessive suds or detergent overuse causing overfill and overflow
• Cracked tub or internal plumbing leak
• Full or damaged drain pan with triggered floater switch
• Faulty floater or leak detection switch in the base
• Control board misreading sensors or sending incorrect fill/drain commands

Troubleshooting steps

1. Stop the machine and ensure safety first: unplug the washer and shut off the water supply.
2. Remove standing water from the floor and under the washer to prevent further damage. Use towels and a wet/dry vac if available.
3. Check for visible leaks: inspect inlet hoses, drain hose, clamps, and fittings. Tighten or replace worn hoses and clamps.
4. Inspect the door boot and tub seals for tears, holes, or deterioration. Replace any damaged seals to stop internal leaks.
5. Examine the drain pump and filter for clogs or broken impellers. Clear debris and test the pump for proper operation.
6. Locate the drain pan and floater switch under the machine. If the pan is full or the floater is stuck, dry it and test the floater for continuity.
7. Check the pressure hose that connects the tub to the pressure switch for kinks, clogs, or disconnection. Replace collapsed or cracked hose.
8. Run a diagnostic or service mode if your model supports it to read stored fault history and sensor values. This helps pinpoint whether the pressure switch, pump, or control board reported the problem.
9. Inspect for signs of internal tub or plumbing cracks. Small leaks inside the cabinet often require partial disassembly and professional repair.
10. If no obvious mechanical fault is found, test electrical components: pressure switch continuity, pump operation, and relevant wiring harnesses. Replace defective parts as needed.
11. After repairs, clear the error (power cycle and run a drain/spin test) and monitor for recurrence before returning the washer to normal use.
12. If the FL error persists or water damage is significant, contact a certified appliance technician. Avoid powering the washer when you suspect persistent leaks.

Maintenance / Prevention Tips

• Inspect inlet and drain hoses annually for cracks, bulges, or loosened clamps and replace every 5 years or sooner.
• Use the proper high-efficiency detergent and follow dosage guidelines to avoid excessive sudsing and overflows.
• Do not overload the washer; overloading can stress seals and create leaks.
• Keep the washer level to prevent uneven loads that can stress seals and cause leaks.
• Clean the pump filter and drain path regularly to prevent clogs and slow drains.
• Check the door boot and drum seals for wear and replace at the first sign of damage.
• Install a drain pan under the washer if your setup allows, and periodically check it for water.
• Ensure the pressure hose and its fittings are secure and free from kinks.
• Run a maintenance wash periodically to flush out detergent residue that can trap water and damage seals.
• Secure hose connections with stainless steel clamps rather than plastic clips when possible.
• Replace any cracked internal plumbing or plastic fittings as soon as they are detected.
• Avoid placing the washer where it can freeze, since frozen lines can crack and leak when thawed.
• Keep the area around the washer clear to make leak detection and cleanup easier.
• Have a professional inspect the washer annually if it sees heavy use or is older than 8 years.

Conclusion and safety notice

The FL code signals a potentially serious leak condition. Because water can cause electrical hazards and structural damage, prioritize safety: shut off power and water immediately when you see FL, clean up standing water, and inspect the obvious components listed above. Simple fixes like tightening a hose clamp are often user-serviceable, but anything requiring internal access, electrical tests, or replacement of seals, pumps, or the control board should be handled by a qualified technician. When in doubt or if the leak is significant, call a professional to prevent further damage and ensure safe, reliable repair.

If you are uncomfortable performing any troubleshooting steps or if water damage is extensive, contact an authorized Whirlpool service provider to diagnose and repair the issue safely.
