We always give credit to Whirlpool for their brilliant washers in our appliance repair articles, especially the Whirlpool duet front display panel.
Recently, many have told us about getting a Whirlpool front load washer F24 error code during a wash cycle.
And that’s what we’re talking about today. So follow along to learn about the Whirlpool washer F24 error and how to fix it.
What Does F24 Mean on a Whirlpool Washer?
The F24 error means there’s an error in the water temperature sensor of your washing machine. We call this a heating temperature sensor failure or a heating circuit failure.
As you might know, the different parts of a Whirlpool washer communicate with each other electrically. For the F24 error, we’re interested in how the water temperature sensor (NTC) and the central control unit (CCU) communicate.
To clarify, the CCU is the “brain” of your washer and controls how the different parts work together to do their job. During any operation your washer is doing, such as the wash or spin cycle, the parts send data to the CCU, which keeps everything in check.
During the water heating step of the wash cycle, the temperature sensor sends a value to the central control board. If this value is out of range, then the CCU will throw you the F24 error to let you know.
There are two main reasons for this whole charade: either your water temperature sensor fails, or the wire connection between the CCU and temperature sensor is faulty. More rarely, the error could happen from a control board failure. Anyhow, let’s get into how to fix the error.
Fixing the Whirlpool F24 Error
Run a Diagnostic Test
First, we want to make sure the CCU isn’t at fault here, and to do so, we run diagnostics.
For this step, pick three buttons that aren’t power, start, or cancel buttons and press them in a sequence three times. For example, if you picked buttons A, B, and C, press ABCABCABC. You must do this in eight seconds.
If the test doesn’t return any errors, then your CCU is fine. But if it does, it means that your CCU is broken, and you’ll need to replace it.
Check the Wiring
Next, it’s time to check the temp sensor wires, but note that the following steps may revoke your warranty if you still have it, so we’d recommend you use it instead in that case. Otherwise, read on and pay attention to the machine’s wiring throughout all the steps.
Make sure your washer is empty, then unplug it. Next, undo the screws holding the lower access panel to remove it. Finally, you’ll see the NTC at the wash tub base next to the heating element (if your washer has one).
If any wires are disconnected, which can happen due to the washer vibrating, reconnect them and test the washer. But if a wire or its connector plug coming in or out of the NTC are faulty or oxidized, you’ll need to get them fixed. You can solder corroded wires and oxidized connectors or replace broken connectors.
We’ll look at the heating element for the next step, so you can skip this if your washer doesn’t have one. First, check the wire harness (the small square-shaped plug) between the heating element terminals. If it’s loose or completely disconnected, then reconnect it tightly into the heater.
Now double-check the wiring, reconnect the rear panel, re-plug the washer, then test it. If it still doesn’t work, then it’s time to check if the NTC is intact.
Check the NTC Sensor
For this step, you’ll need an Ohmmeter for a resistance check on the NTC sensor.
Repeat the first steps of the last solution to undo the rear panel and reveal the NTC. Then, unplug the NTC harness and use your Ohmmeter to measure resistance. Use the following chart to check if the readings look good.
|Temperature Meter||Resistance in K Ohm|
If your readings don’t correspond to this chart, then you need to replace your NTC. Luckily, NTC sensors aren’t expensive, and you can find one for under $20.
Other Whirlpool Duet Washer Error Codes
We’ll wrap up our F24 troubleshoot here. To recap, this error means there’s a water temperature sensor error, and it could be caused by faulty wiring or a broken temperature sensor. Fortunately, it’s easy to fix faulty wiring, and a broken NTC is cheap to replace.
