How to Fix F5 Error on Whirlpool Washer: A Comprehensive Guide for Appliance Repair


A Whirlpool washer is an essential appliance in every home, ensuring that laundry is a smooth operation. However, like any other appliance, Whirlpool washers can experience technical issues, such as encountering the dreaded F5 error code. This code typically signifies a fault with the temperature sensor. If you’ve seen the F5 error on your Whirlpool washer, don’t fret – we’ve got you covered. In this article, we will provide you with an in-depth guide on how to fix the F5 error on your Whirlpool washer and offer actionable tips to get your appliance back up and running.

Understanding the F5 Error

Before we discuss how to fix the issue, it is essential to understand what the F5 error means. The F5 error on a Whirlpool washer typically signals a problem with the water temperature sensor, also known as the NTC (Negative temperature coefficient) sensor. The sensor is responsible for monitoring and controlling the water temperature during the washing cycle. When it fails, the washer’s control unit cannot accurately measure the water temperature, leading to errors in the washing process and, consequently, the error code.

Actionable Tips to Fix the F5 Error on your Whirlpool Washer

Now that we understand what the F5 error is, let’s dive into the actionable tips you can follow to fix the issue:

1. Disconnect the power supply: Before attempting any repair or troubleshooting, always ensure that your washer is unplugged from the power source to avoid any risk of electric shock.

2. Inspect the wiring: Begin by checking the wiring connections between the NTC sensor and the control unit. Look for any loose or damaged wires and fix or replace them as necessary.

3. Examine the water temperature sensor (NTC sensor): Locate the NTC sensor, usually found near the heating element of the washer. Check if it is visibly damaged, corroded, or faulty. If so, replace the sensor.

4. Test the NTC sensor: To confirm whether the NTC sensor is the root cause of the problem, you can use a multimeter. Remove the sensor from the washer and test its resistance at room temperature. It should read between 10-20K ohms approximately, depending on your washer model. If the reading is outside this range, you’ll need to replace the sensor.

5. Clean the inlet filter: The F5 error can also be caused by a clogged inlet filter, which may affect the water temperature. To fix this, remove the inlet hose from the washer, clean the filter screen with a brush, and reinstall the hose.

6. Check the heating element: A faulty heating element can also trigger the F5 error. Check the heating element with a multimeter for continuity – if it shows none, the heating element needs replacement.

7. Inspect the control unit: If all the above checks have been performed and the issue persists, it may be attributed to a faulty control unit. If you suspect this is the case, you should consider contacting a professional technician to evaluate and replace the control unit if necessary.

8. Reset your Whirlpool washer: After completing all the necessary checks and repairs, reset your washer by plugging it back in, and press and hold the “Start” button for about 5 seconds. This should clear the error code and restart the washing process.


With these actionable tips, you should be well-equipped to fix the F5 error on your Whirlpool washer, allowing you to get back to your regular laundry routine. Remember, always prioritize safety while working with electrical appliances, and don’t hesitate to reach out to a professional technician if you are unsure about any procedures. Happy washing!
