Whirlpool Duet Washer Error Code F01

The Whirlpool washer is one of the most common washing machines today. But it’s not uncommon to find a Whirlpool washer error code if your machine is getting old, and the F01 error code is among the most common error codes you’ll see on the display board.

Fortunately, fixing the error is no big deal, so follow along as we explain the F01 error, its causes, and how to resolve it.

What Does a Whirlpool Washer F01 Error Mean?

If your Whirlpool washer is showing an F01 error code and fails to start the wash cycle, it means there are issues in your washer’s electronics. It could be a fault in a short circuit, a dedicated circuit, or a circuit connecting two major parts: the main control board (central control unit) or the memory module (EEPROM).

The main control board is the electronic module that acts as the “brain” of the washing machine. On the other hand, the electrically erasable and automatically reprogrammable ROM (EEPROM for short) is the re-recordable memory of the device. These two parts are what you should look out for if you’re getting an F01 error code.

What Causes an F01 Error Code?

But how can the control board or EEPROM cause an error code in your Whirlpool model washer?

Damaged Transistor or EEPROM

Whirlpool uses an EEPROM capable of re-recording up to a million times. There’s a transistor responsible for storing information on the memory about the selected mode. The EEPROM then sends the signal to the equipment and electric motor about the selected mode.

If the EEPROM or its transistor are damaged, it causes a signal loss, and your washer doesn’t receive your commands, and it lets you know through an error code.

No Connection Between EEPROM and Central Control Unit

You could be getting an F01 error code because of a communication error in one of the connections between the electronic control board and the EEPROM if a cord or wire connecting the two parts is faulty.

Burnt-Out Central Control Unit

The worst-case scenario is a burnt-out central control unit resulting from a power surge.

Unfortunately, you’ll have to buy a new electronic module, which is expensive enough that you might want to consider a new washing machine.

How to Fix the Whirlpool Washer F01 Error Code

Let’s look at some of the repairs you could perform on your Whirlpool duet washer if you’re getting an F01 error code.

Restart the Machine

The first thing you can try is restarting the machine, a relatively simple process.

To restart, unplug the power cord and check the outlet’s voltage, grounding, polarity, and dedicated circuit. If everything is normal, plug the cord and wait a couple of minutes, then switch the machine back on through the appropriate button and see if it works.

This process restarts the machine and can repair the error. But if the error persists, move on to the next step.

Solder the EEPROM Contacts

If your EEPROM’s transistors are damaged and unable to deliver signals between different parts of your Whirlpool washer, you can try soldering the cords and pieces connecting to your EEPROM. If this doesn’t fix the problem, you’ll need a replacement (a new memory module), which should be relatively inexpensive.

Normal Signal Conductivity Error Between the CCU and EEPROM

If the problem is in the connections between the central control unit and the EEPROM, you should start by testing the input/output of the central board and inspecting the main elements of the washer.

First, disconnect your Whirlpool washer from its power supply and unscrew the top panel to access the washer’s electronics.

After unplugging it, check the connections around the interference filter (IF). For reference, the IF is a small, cylindrical part that’s usually white or silver. Make sure all the connections to the IF are secure.

Finally, make sure the washer’s connectors and plugs aren’t faulty and are tight.

If the error is still there after these inspections, then it’s time to measure the washer’s voltage. Connect the voltmeter to the IF, turn on the machine, and set the voltmeter to alternating current. A typical voltage is around 120 volts, so if the meter reads a much higher voltage, that’s the source of the problem.

Alternatively, if you don’t have a voltmeter, you can inspect the power cord. If it looks too faulty, that’s probably because of high voltage. If the cord looks normal, then solder the IF. Otherwise, if everything fails, you’ll need to get it replaced or seek a technician to get it running.

Replace the Burnt-Out Central Control Unit

The last possible cause for an F01 error code is a burnt-out central control unit. Unfortunately, you can’t repair these units, and you’ll have to get a new unit, which is costly. So you might as well get a new washer altogether if you’re going to spend that much.

However, if you choose to replace the control unit, it’s not a complicated process. But before you start disassembling anything, we recommend taking a picture of that section of the washer so you can reference where to place everything. Then remove the old unit and replace it with the new unit.

Washing Machine Maintenance

The best thing you can do to maintain your washer’s lifespan is regular maintenance. Washing machine maintenance should already be part of your home maintenance since it’s such an essential appliance that needs to be working properly. Sometimes, a wrong detergent or clogged water particles could cause an issue without you noticing.

So, if you notice even the slightest irregularities in your washer’s performance, be sure to address them promptly or seek an appliance repair service. Appliance repair is a serious issue.

The Bottom Line

In short, an F01 error code could result if there’s a problem with the EEPROM (memory module), the control unit, or a communications issue between them. You can try restarting the machine before anything to see if it solves the problem.

If the problem is still there and it’s in the EEPROM, you can solder its transistors or replace the EEPROM entirely. But if the problem is in the connection between the EEPROM and CCU, check the connections around the interference filter and inspect the main cords, then solder or replace any faulty cords.

However, if the problem is a burnt-out control board, you’ll have to replace it entirely, which costs hundreds of dollars and might prompt you to buy a new washer. That’s why most people don’t opt for a replacement board.
