by Upgraded Home Team

With newer models of washing machines, it can become frustrating running into an error code. Many modern-day washing machines are programmed to display two or three-digit error codes in the case of any issues. These are designed to make identifying the problem easier, but sometimes they can be a double-edged sword.

If an F20 error code shows up on your Whirlpool Duet Washer, this is due to a water supply problem. This means no water is flowing into the machine and cancels the cycle. This is likely due to faulty components or dirty filters, meaning you will need to replace either the clog or connectors.

If you’re worried that there may be a more complex issue going on, don’t worry. We’ve taken the time to research all the reasons why the error F20 code may appear on your screen. Below, we’ve listed possible fixes and what you need to know to get your whirlpool duet washer and dryer working again.

What is the F20 Error Code & What Does it Mean?

The F20 error code indicates that there is an issue with the machine’s main water supply. There are a few reasons why your washing machine may end up showing this error. Out of all the reasons, the most common is when there is no water dispersed into the water. However, another issue is when the pressure switch trip is not being detected.

When the machine detects that this issue is occurring, it will automatically cancel the washing cycle. Errors like this can be frustrating because the device will not work until the problem is fixed. Either you or a professional will need to go in and fix the water dispenser manually.

How to Fix the F20 Error Code

An F20 code can easily be fixed by checking the following areas. Below, we’ve listed a few common fixes that you’ll be able to find yourself. It is recommended to call a professional or the manufacturer if you don’t know what you’re doing.

How to Check Connectors

One prevalent issue is that the hot and cold water connectors are either misaligned or turned off. There are three components you’ll need to check to ensure it’s properly connected.

Step 1: Locate Water Hookups

The water hookups are generally located in the back of front-facing washers. However, every model of the washing machine is different. You should very quickly locate where the hookups are because they will be plugged into the wall. Once you find the two hoses, you’ll need to check the connections.

Step 2: Inspect Connectors

Look to see if both the hot and cold water hookups are screwed incorrectly. If they are loose, this could be one reason why you get the F20 code. If they are hooked up correctly, then you should check to see if the hose is damaged.

Step 3: Screw Back On or Replace Hose

If there is any damage, we recommend unscrewing the hose and screwing it back in. Hoses that are broken will need to be replaced. Use your user manual to identify what type of hoses you’ll need. If you don’t have the manual, contact the washer or dryer manufacturer.

How to Check Hose for Kinks

Similarly to a garden hose, a hose of the washing machine can become kinked. A kinked hose will prevent water from flowing into the engine. To avoid this, you’ll need to observe the hose.

If you can’t see the hose, you can try gently tugging on the hose to straighten it out. If the issue persists, then you may have to move the machine. To unkink a hose, you’ll need to find where the water is being cut off. Once you straighten the hose, you can push the machine back and try again.

How to Check Clogged Water Inlet Valve

The inlet valve is prone to becoming clogged when there is a buildup of debris. Some common debris that can clog inlet valves is dirt, mineral deposits, and small objects. Luckily, cleaning an inlet valve only takes a few minutes. You’ll need the following tools on hand;

  • Slip-joint pliers
  • Towel
  • Noodle-nose pliers
  • Inlet valve screen replacements
  • A utility knife

Step 1: Cut Off Power Supply

Before you open up your washing machine, it’s best to shut off the power. You can do that by unplugging your washing machine from the wall. There should be a cord located at the back of the device that is plugged into an outlet. Make sure to unplug it to avoid getting shocked or electrocuted thoroughly.

Step 2: Turn Water Off

The water valves need to be completely shut off at this point. They should be located behind the washer. Crank the valves so that it cuts off the water supply. There should be one for hot water and one for cold water. Make sure to turn both of them completely off.

Step 3: Unscrew Hoses & Take Out Filter

The water inlet valve can only be observed once the hoses are unscrewed. You’ll need to remove the hose using a set of pliers carefully. Place a bucket underneath your workspace, as water will begin to leak out.

Use pliers to grip the back of the filter before pulling it straight out. You can use a towel or q-tip to remove anything blocking the filter. Once you’ve cleaned out the area, you can put a new filter or the clean filter back into place and reattach everything.

How to Check Water Pressure

Another common issue is that your washer may have low water pressure. Unfortunately, there isn’t much you can do when it comes to low water pressure. If your home is hooked up to the municipal water supply, you won’t have much control over adjusting your home’s water pressure.

However, there are steps you can take to check if the water pressure is working properly.

Step 1: Locate Water Hose

First, you’ll need to move the washer out so that you can see the water hoses. The water hoses should be located on the back of the washer.

Step 2: Check Hose

After you move the washer, place a bucket underneath the hose area to catch dripping water. From there, you’ll need to unscrew the hose and check the opening. Look for any debris located in the hose opening or the opening to the washer.

Step 3: Check Filters

There should be a small filter located where the hose was connected on the dryer. Check to see if there is any debris caught in the filter. At times, a filter may need to be replaced due to being overused. To do that, get a replacement filter for your washer model.

Switch to High-Efficiency Detergent

Regular detergent is suitable for washing clothes, but high-efficiency detergent can help keep your washer in good shape. We see many people who have an updated high-efficiency washer, but they aren’t using HE detergent. If you accidentally used regular detergent instead of HE detergent one or two times, there’s no need to worry. However, you don’t want to do this on a regular basis.

Using regular detergent produces more soap scum and suds, which can ruin your machine over time. It can cause a buildup of residue that can clog open areas and cause the unit to break down. Switching to a high-efficiency detergent allows the clothes to be washed without the excess residue.

Flood Preventing Devices

Flood prevention devices can be installed to help regulate water pressure. The device will need to be installed inside the water hose. What this device does is close off the water when the psi is over 2 gallons per minute.

On the upside, the flood prevention device will help shut off the water to prevent a leak. However, sometimes these devices can also cause issues. When malfunctioning, the valve may shut off the water pressure, causing the error code.
