The 5d code error code on a Whirlpool washer typically means your machine has excess suds. If you have experienced this code, either once or repeatedly, and are wondering how to prevent it, this article will offer tips and advice on the best steps to take. 

While this error code may look like it says “5d,” it actually says “Sd,” but it is often misread as “5d” due to the digital font used on the display of many Whirlpool washers. On some Whirlpool washers, this error code can also display as “Sud.”

Therefore, this guide is suitable for anyone experiencing the “5d,” “Sd,” or “Sud” error code on their Whirlpool washer. Let’s begin.

How to fix the 5d code on a Whirlpool washer

If your Whirlpool washer has too many suds inside and displays the 5d code, the best initial step to take is to let it continue its cycle. Your washer will try to deal with the issue automatically by running a suds reduction routine.

This typically involves the machine pausing its cycle, adding more water, and rinsing for longer to dissolve the excess suds. It may repeat this process a few times until all the excess suds have been removed.

If the 5d error code is flashing on the display of your Whirlpool washer, you will need to manually reselect a wash cycle and let it run through again to remove the excess suds. However, set it to a cold wash temperature when doing so, and remember, DON’T add any detergent.

While these measures should resolve the issue in most cases, they don’t get to the root cause of what triggered excess suds in the first place. This means the problem could arise again. 

If your washer has to deal with excess suds frequently, it could cause a spike in utility bills or faster deterioration of your machine’s components.

Causes and prevention of the 5d/Sd/Sud error code

So, what could be causing excess suds and the 5d error code to appear on your machine, and can you do anything to help prevent it from occurring again? Let’s take a look.

Are you using the right detergent?

Most modern Whirlpool washers are designed to use high-efficiency (HE) detergent. This type of detergent is specially formulated to produce less suds. Therefore, using the wrong kind of detergent, i.e., non-HE detergent, can cause several problems for your machine.

One of these problems is excess suds, leading to the 5d error code. Other problems non-HE detergent can cause in HE washers include inefficient cleaning, residue left on laundry, and even damage to the machine. So, if you haven’t checked already, it’s definitely worth confirming you are using HE detergent and that nothing else has been used accidentally.

Are you using too much detergent?

Even if you are using the right HE detergent, it’s easy to use too much of it accidentally. HE washers are designed to work using less detergent, so if more than the recommended amount is used, it can lead to excess suds and the pesky 5d error code.

The best way around this is always to measure the amount of detergent you use. This measurement should be based on the detergent manufacturer’s instructions and the load size of your laundry. Using the right quantity of detergent helps ensure both effective and efficient washing.

Is the washer being overloaded?

Sometimes, the 5d error code displays as a result of overloading the washer. This is because it may not be able to drain water properly when it is overfilled, leading to the accumulation of water and suds. Therefore, it’s important to stick to the loading guidelines for your Whirlpool washer model.

If you are midway through a wash cycle, try unloading some of the items from the washer and ensuring the remaining items are distributed evenly in the drum, then restart the cycle to see if it resolves the error code.

Check for drainage issues

A blocked drainage system can stop water from draining adequately, backing up the system and causing an accumulation of suds in your washer, which may trigger the 5d error code.

Blockages may occur in the drain hose, water pump, or filter, so it’s worth visually inspecting all these for obstructions if the error code persists. Remember to unplug the washer and cut off the water supply before attempting this, and refer to your user manual for information on locating these components.

Check the pressure switch

The pressure switch monitors the water levels in your washer. However, if it becomes faulty, it can affect the water levels by allowing too little or too much water into the machine, which could lead to extra suds and the 5d error code.

To check the pressure switch, start by switching off your machine’s power and water supply. Locate the pressure switch with the help of the user manual. Then, visually inspect it for signs of damage, loose connections, or faulty wiring. You can also test it with a multimeter for continuity. Also, check the pressure tubing attached to the switch, ensuring it’s free of any blockages or damage.


The 5d/Sd/Sud error code generally means there are excess suds in your machine. It’s not always a major cause for concern, as it can often be fixed with some simple changes to your washing routine, such as following the manufacturer’s instructions on what detergent is suitable, how much detergent to use, and loading guidelines.

However, this error code can also sometimes appear when there is an issue with your Whirlpool washer’s components, such as the drainage system or pressure switch. If you are uncomfortable tackling these issues, don’t hesitate to contact a qualified appliance repair technician to help you resolve the error.
