What Does “FL LO” Mean on a Whirlpool Washer? Understanding and Troubleshooting
The error code “FL LO” on a Whirlpool washer indicates a low flow condition during the fill cycle. This means the washer isn’t getting enough water in the expected time.
Decoding the “FL LO” Error: A Common Washer Issue
Encountering an error code on your washing machine can be frustrating. The “FL LO” error on a Whirlpool washer is a frequent issue related to the water supply. Understanding the reasons behind this code and how to troubleshoot it can save you time and money on repair services. This article explores the causes of this error, step-by-step troubleshooting methods, and preventive measures.
Potential Causes of the “FL LO” Error
The “FL LO” error, indicating low flow, can be triggered by several factors relating to the water supply, water inlet valve, or even the washer’s drain system.
-
Water Supply Issues:
- Closed or Partially Closed Faucets: The water supply faucets connected to the washer might not be fully open.
- Kinked or Blocked Water Hoses: The hoses carrying water to the washer could be bent, twisted, or obstructed.
- Low Water Pressure: Insufficient water pressure in your home can prevent the washer from filling properly.
-
Washer Component Problems:
- Clogged Water Inlet Valve Screens: Small screens in the water inlet valve(s) can become clogged with sediment, restricting water flow.
- Faulty Water Inlet Valve: The valve itself might be malfunctioning, preventing it from opening fully.
- Drain Issues: If the drain hose is siphoning water as the washer fills, the ‘FL LO’ error could appear.
Troubleshooting the “FL LO” Error: A Step-by-Step Guide
Here’s a systematic approach to diagnosing and resolving the “FL LO” error on your Whirlpool washer:
-
Check the Water Supply:
- Ensure both hot and cold water supply faucets are fully open.
- Inspect the water hoses for kinks, bends, or visible damage. Straighten any kinks and replace damaged hoses.
-
Assess Water Pressure:
- Test the water pressure at the faucets connected to the washer. A simple test is to attach a hose and see if the water flow is strong. If the pressure is weak, contact your local water provider.
-
Inspect and Clean Water Inlet Valve Screens:
- Turn off the water supply to the washer.
- Disconnect the water hoses from the back of the washer.
- Carefully remove the small screens from the water inlet valves (usually located inside the hose connections).
- Clean the screens thoroughly with a brush and water.
- Reinstall the screens and reconnect the hoses.
-
Check the Drain Hose:
- Ensure the drain hose is properly positioned and not inserted too far into the drainpipe.
- The drain hose should have an air gap to prevent siphoning.
- Check for clogs or obstructions in the drain hose and drainpipe.
-
Power Cycle the Washer:
- Unplug the washer from the power outlet for a few minutes.
- Plug it back in and restart the wash cycle. This can sometimes reset the control board and clear the error.
-
Test the Water Inlet Valve (Advanced):
- This step requires some electrical knowledge. If you’re not comfortable, contact a qualified appliance repair technician.
- Using a multimeter, check the water inlet valve for continuity. If there’s no continuity, the valve is likely faulty and needs to be replaced.
Preventing Future “FL LO” Errors
Taking preventative steps can minimize the likelihood of encountering the “FL LO” error in the future:
- Regularly Inspect Hoses: Check the water hoses for wear and tear, kinks, or bulges. Replace them every 3-5 years as a preventative measure.
- Clean Inlet Valve Screens Periodically: Make it a habit to clean the inlet valve screens every 6-12 months.
- Address Low Water Pressure: If you consistently experience low water pressure, consult a plumber to identify and resolve the underlying issue.
- Use a Water Filter: Install a water filter to reduce sediment and mineral buildup, which can clog the inlet valve screens.
Understanding the Error Code “FL LO” in Relation to Washer Functionality
The “FL LO” error directly impacts the washing machine’s ability to perform its core function – cleaning clothes effectively. Insufficient water means the detergent won’t dissolve properly, and clothes won’t be adequately rinsed. This can lead to residue buildup on your clothes and within the washing machine itself.
Water Pressure and its Impact on Washing Machine Performance
Adequate water pressure is crucial for optimal washing machine performance. Most washing machines require a minimum water pressure to fill correctly within the allotted time. Low pressure extends the fill time, potentially triggering the “FL LO” error and leading to incomplete wash cycles.
Troubleshooting Tools: What You’ll Need
For troubleshooting the “FL LO” error, here are a few handy tools:
- Screwdrivers: For removing panels or accessing components.
- Pliers: For loosening hose clamps.
- Bucket: To catch water when disconnecting hoses.
- Brush: For cleaning inlet valve screens.
- Multimeter (Optional): For testing the water inlet valve.
Frequently Asked Questions (FAQs)
What is the most common cause of the “FL LO” error on a Whirlpool washer?
The most common cause is a partially closed water supply valve. Always ensure both hot and cold water faucets are fully open before further troubleshooting.
How do I clean the water inlet valve screens?
Turn off the water, disconnect the hoses, remove the screens from inside the hose connections, and clean them thoroughly with a brush and water. Reinstall them before reconnecting the hoses.
What happens if I ignore the “FL LO” error?
Ignoring the “FL LO” error can lead to inefficient washing, detergent residue on clothes, and potential damage to the washer’s internal components due to prolonged operation with insufficient water.
Can low water pressure damage my Whirlpool washer?
While not directly damaging, consistently low water pressure can strain the water inlet valve and lead to premature failure. It can also affect the wash quality and cycle times.
Is it safe to run the washer with the water supply partially open to avoid the error?
No, it’s not recommended. While it might temporarily bypass the error, it can still lead to inefficient washing and strain the washer’s components. Fix the underlying cause of the low flow instead.
How do I test the water inlet valve with a multimeter?
Disconnect the power to the washer, disconnect the wires from the water inlet valve, and test for continuity across the valve terminals. A lack of continuity indicates a faulty valve. If unsure, consult a professional.
Can a clogged drain cause the “FL LO” error?
Yes, a severely clogged drain hose or drainpipe can create backpressure and interfere with the water filling process, potentially triggering the “FL LO” error.
How often should I replace the water hoses on my washing machine?
It is generally recommended to replace water hoses every 3-5 years to prevent leaks and bursts, regardless of their apparent condition. Prevention is key.
What if I’ve checked everything, and the “FL LO” error still appears?
If you’ve exhausted all troubleshooting steps and the “FL LO” error persists, the problem might lie with the washer’s control board or a more complex internal issue. Contact a qualified appliance repair technician.
Does the “FL LO” error mean there’s a leak somewhere?
Not necessarily. “FL LO” specifically indicates low flow, not necessarily a leak. However, if you also notice water leaking, address that separately as it’s a different problem.
What does it cost to have a professional diagnose and fix the “FL LO” error?
The cost can vary widely depending on location and the specific issue. Expect to pay anywhere from $75 to $200+ for diagnosis and repair.
Will using more detergent help if the washer is not filling properly?
No, using more detergent will not resolve the underlying cause of the “FL LO” error. In fact, it can exacerbate the problem by leading to excessive suds and residue buildup. Focus on fixing the water flow issue first.
