The FL error on your Maytag Washer means the machine has detected a water flow or level problem, often shown as “LO FL” (low flow) on the display. This usually points to poor water supply to the unit, a clogged inlet filter, or a faulty pressure sensor, and it can often be fixed without calling a technician.

Error code FL
Meaning Low or no water flow detected during fill cycle
Severity Medium — washer won’t complete cycles until resolved
Time to fix 15–40 minutes
Tools needed Pliers, small bucket or towel

What the FL error means

The FL (or LO FL) code appears when your Maytag washer’s control board senses that water isn’t entering the drum fast enough or in the expected amount during the fill stage. The machine is designed to pause or stop the cycle rather than run with insufficient water, protecting the motor and preventing an unbalanced wash. This is a safety and performance check, not a sign of a serious mechanical failure in most cases.

Common causes

  • Water supply valves partially closed or not fully turned on
  • Kinked, twisted, or bent water inlet hoses
  • Clogged inlet screens/filters where hoses connect to the washer
  • Low household water pressure feeding the machine
  • Faulty water inlet valve that won’t open properly
  • Defective pressure sensor or water level switch misreading fill levels

How to fix the FL error

  1. Check the water taps: Make sure both hot and cold water valves behind the washer are turned fully on.
  2. Inspect the hoses: Straighten any kinks or bends in the inlet hoses and confirm they aren’t pinched behind the machine.
  3. Clean the inlet filters: Turn off the water, disconnect the hoses, and use pliers to remove and rinse the small mesh screens inside the hose connections.
  4. Test water pressure: Run water from an outdoor tap or another faucet to confirm your home has adequate pressure; low pressure may need a plumber’s attention.
  5. Reconnect and reset: Reattach the hoses securely, restore water supply, and run a quick test cycle to see if the code clears.
  6. Call for service: If the error persists after these checks, the water inlet valve or pressure sensor may need replacing by a qualified technician.

FAQ

Can I keep using my washer with the FL error showing?
No, the washer will typically pause the cycle until the water flow issue is resolved, so it’s best to fix it before continuing.

Is the FL code related to other Maytag error codes?
It’s a separate issue from control board faults like those covered in the Maytag Washer F1 Error Code: Causes and Fixes or Maytag Washer F2 Error Code: Causes and Fixes guides, though all point to specific system checks.

Do I need a plumber to fix this?
Usually not — most FL errors are solved by checking taps, hoses, and filters yourself, similar to troubleshooting steps used for the Maytag Washer F3 Error Code: Causes and Fixes and Maytag Washer F5 Error Code: Causes and Fixes. A plumber is only needed if household water pressure itself is the problem.
