The 1F error on your Maytag Washer means the control board has detected a communication failure between the main control board and the motor control unit. This is often triggered by a power interruption or a faulty wiring connection, and in many cases can be cleared with a simple reset.

Error code 1F
Meaning Loss of communication between the main electronic control board and the motor control board
Severity Medium — washer usually stops mid-cycle but is repairable at home
Time to fix 10–45 minutes
Tools needed Multimeter (optional), screwdriver

What the 1F error means

The 1F code appears when the washer’s main control board loses its connection with the motor control board, usually because of a wiring fault, a power surge, or a failing board component. It’s closely related to other communication codes such as the Maytag Washer F1 Error Code, which shares a similar root cause. Most of the time the washer will pause the cycle and flash the code on the display until the issue is cleared or resolved.

Common causes

  • Temporary power surge or brownout that disrupted board communication
  • Loose or damaged wiring harness between the main control board and motor control board
  • Corroded or dirty connector pins on either control board
  • Failing main control board or motor control board
  • Static discharge affecting the electronics during operation
  • Faulty ground connection causing electrical noise on the control circuit

How to fix the 1F error

  1. Power cycle the washer: Unplug the washer for 60 seconds, or switch off the breaker, then restore power. This clears many temporary communication faults.
  2. Check the wiring harness: Unplug the washer, remove the cabinet panel, and inspect the wiring between the main control board and motor control board for looseness, fraying, or corrosion.
  3. Reseat all connectors: Disconnect and firmly reconnect every connector on both control boards to rule out a poor connection.
  4. Test board continuity: Use a multimeter to check for continuity along the wiring harness if you’re comfortable working with electrical components.
  5. Inspect for corrosion or damage: Look for burnt marks, corrosion, or discoloration on both boards, which indicate a component failure needing replacement.
  6. Replace the faulty board: If the wiring checks out fine but the error persists, the main control board or motor control board likely needs replacing — this is best done by a qualified technician if you’re unsure.

FAQ

Can I keep using the washer if the 1F error keeps coming back?
It’s not recommended. Repeated communication faults can leave the washer stuck mid-cycle and may signal a worsening board or wiring issue that could cause further damage.

Is the 1F error the same as the F1 error?
They’re related but not identical. Both involve control board communication issues, though F1 codes often point more specifically to the main control board. See the Maytag Washer F1 Error Code guide for more detail.

Do I need a technician to fix this?
Not always. A power cycle or wiring check can resolve it yourself, but board replacement is safer left to a professional if you’re not confident working with electrical parts.
