What SD Or Sud Error Code Mean on A Whirlpool Washer?

If your Whirlpool washer stops in the middle of a cycle and displays an SD error code, you need not panic. Newer technologies in the washer industry ensure the effective use of water and detergent for a better cleaning of fabrics.

How To Troubleshoot & Fix SD or SUD Error On Whirlpool Washer?

After knowing all the probable causes, you might want to try to fix your Whirlpool washer SD code starting from the simple one. This will help you recognize the issue beforehand and act accordingly.

1. Perform Soft Reset

Whirlpool washers use high-efficiency (HE) liquid detergents that are specially formulated so as not to generate excessive suds or foam.

However, using regular detergent instead of HE detergent results in forming a high volume of suds in the presence of a small amount of water.  A similar case happens if you use increased HE detergent in the washer.

Moreover, not maintaining the detergent and fabric type (to be washed) ratio also causes a similar problem. As a result, the excessive suds in the washer drum fail to spin and display the SD or code.

That is you should always refer to the user manual to know what HE detergent you should use in your Whirlpool washer.  To fix the code you need to perform a soft reset of the washer.

Firstly, cancel the existing wash cycle followed by the rinse and drain cycle to remove all suds from the washer drum. After that power down the washer and unplug it.

Shutting down the circuit breaker would also do the same. Wait for a while (1-5 minute) and reboot the washer. Start a fresh cycle and check if it shows the error code again.

2. Clean & Clear Drain Pump Filter

Your Whirlpool washer might also display the SD or SUD error code for clogged or malfunctioning drain pump filters.

When the washer detects excessive suds in the drum it stops the wash cycle and starts to rinse and drain the suds to ensure better cleaning.

The drain pump activates to carry the foamy water out from the washer basket hence it runs for a while to eliminate the code. However, suds in a higher volume can clog the drain pump filter and prevent draining suds from the washer.

Many users have reported that small pieces of clothes such as socks also get in the way of the drain pump hindering proper suds draining. Thus the clogged drain pump fails and the washer shows an Sd or Suds code.

To solve this you need to physically access the drain pump located underneath the washer. Unscrew the lower front panel to get to the drain pump. Place a tray of pieces of clothes underneath the pump.

Afterward, gently rotate the pump cover counterclockwise. Let the pump flush all accumulated suds and water from inside. Clean the pump properly and check the drain hose if it’s functioning properly.

Reassemble and reset the washer. Check if the error code disappears by starting a fresh wash cycle. If not you might need to change the entire drain pump.

3. Repair/Replace Impeller Hub

The agitator in Whirlpool or impeller in Whirlpool washers tends to disengage with the basket after being used for years.

Thus, using excess detergent results in too many suds, and eventually, it goes beneath the impeller hub. As a result, this slightly restricts the spin of the impeller along with the basket during the rinse and drain cycle.

To get access to the tub hub, remove the agitator blade using a specific socket wrench. Nextly, remove the hub from the shaft by unscrewing six Phillips head screws.

If the gear teeth inside the top or bottom hub are worn and torn you need to replace them with OEM. After replacing the hub in the kit, reassemble everything and reset the washer.
