Whirlpool Washer Error Code F51

Suppose your Whirlpool appliance is displaying the error code F51 on the screen. In that case, it usually means that there’s a problem in the electric motor rotor’s position or a damaged lower wiring harness that leads to the control board. This can cause improper rotation of the washer’s drum.

Usually, this error code can be fixed by the user without requiring professional help. In this guide, we’re going to explore all the possible causes of the code F51 in Whirlpool appliances and how to fix them. So, without further ado, let’s get right to it!

How to Fix the Error Code F51 on a Whirlpool Cabrio Washer

When diagnosing your Whirlpool washing machine, it’s important that you check every component in the right order. Why? Simple because each element has a higher chance of causing the error code than the other.

You wouldn’t want to check a component that has a 5% chance of causing the error while leaving the component with an 80% chance unchecked.

Putting that aside, follow these steps to clear the error code F51 from your washer:

Check if There’s a Glitch

In some cases, this error code may appear because of a glitch. You can get rid of that glitch by resetting the Cabrio washer as follows:

  • Unplug the power cord
  • Wait for a few minutes
  • Plug the power cord back in and start a new wash cycle

If that didn’t work, proceed with the following.

Unload Some Items

If this is the first time your Whirlpool washing machine displays the fault code F51 in the middle of a washing cycle, it could be because of overloading the drum, which causes uneven rotation. Try removing some heavy items from the drum and see if it solves the problem.

Inspect the Motor Rotor Position Sensor and the Control Board

Inspect the Motor Rotor Position Sensor and the Control Board

A malfunctioning Rotor Position Sensor (RPS) is one of the most common reasons for the error code F51. If the sensor is sending out an incorrect corresponding signal or not responding at all, the error code F51 will appear on display, and the washer will stop working.

Sometimes, the problem isn’t in the RPS sensor itself. There could be a problem with the motor control connector between the sensor and the main control panel.

To check the rotor position sensor and the motor connector, follow these diagnostic steps:

  • Turn off the washer.
  • Pull the washing machine away from the wall a bit so that you’re able to stand and squat behind it.
  • Remove the back access panel.
  • Locate the P5 and P10 plug connectors to ensure that they’re connected properly.
  • Inspect the wiring connections between the lower wiring harness and the washer control board. Look for any signs of damage like kinks or melts.
  • Test the machine after repairing or replacing the drive motor connector and see if the issue is resolved.
  • If you’re still having problems with the washer, then you probably need to replace the RPS sensor with a new one.

Remove Any Foreign Objects in the Drum

Remove Any Foreign Objects in the Drum

If there’s a metal piece or any other jammed object in the drum, it may cause the drum not to rotate uniformly, triggering the code F51. Unload the laundry and inspect the drum for foreign objects carefully. If you spot a foreign object between the walls of the tank and the drum, remove it immediately.

Tighten the Bolt at the Bottom

There’s a hex bolt at the bottom of the washer that could cause an error code. Try tightening the loose bolt a bit and see if the error goes away.

How Do I Run a Diagnostic on My Whirlpool Cabrio Washer?

To enter the automatic test mode on your Whirlpool Cabrio washer, follow these steps:

  • With the knob set at a 12 o’clock position, do the following combination: left – right – right – right – left – right. This should cause the dials on the control panel to start blinking.
  • Turn the knob until it reaches the “spin cycle.”
  • Push the start button to initiate a diagnostic test for error codes.

If the automatic mode hasn’t helped much, you can try checking out the motor in manual test mode that enables you to diagnose the problem yourself.

Fixing the F51 error code is pretty straightforward. If unloading some items didn’t resolve the issue, then you’re probably dealing with a problem in the lower harness wiring between the RPS sensor and the main control board. If the connections look good, replace the sensor.

Suppose the visual inspection didn’t resolve the fault code. In that case, your best bet would be to contact the repair center for professional assistance.

Oh, and remember, if you’re going to diagnose the washing machine yourself, it’s essential to put your safety before anything else. Don’t attempt to inspect the washer while it’s powered on, and if you’re going to remove the access panel, wearing protective gear might be a good idea.
