When the SUD Error Occurs on a Maytag Washer

The Sud error code on Maytag washing machines occurs when an excessive amount of detergent, or the wrong type, is used, causing an overflow of suds.

You may usually see this code during the wash cycle when the machine detects suds beyond the normal level, impeding proper washing and rinsing.

Which Maytag Washer Parts Cause the SUD Error Code

Understanding the components involved in the Sud error is important to find a solution:

1. Detergent Dispenser: Dispenses detergent into the washing machine. An issue with the dispenser can contribute to excessive suds.
2. Water Drain System: The drain pump and hoses remove water from the drum. Excessive suds can affect the drainage system, triggering the Sud error.
3. Pressure Switch: The pressure switch monitors the drum’s water level. Excessive suds can interfere with the pressure switch’s operation, resulting in the error code.

How to Resolve This Issue

To solve SUD error on Maytag washing machine, you need to follow the next steps:

Step 1: Stop the Wash Cycle

• If the Sud error appears, stop the washing machine and allow it to pause the cycle. The machine will attempt to reduce suds and continue after a brief pause.

Step 2: Reduce Detergent Usage

• Review the detergent manufacturer’s guidelines and use the recommended amount for the specific load size.
• Avoid using excessive amounts of detergent, as this can lead to oversudsing.

Step 3: Check Detergent Type

• Ensure that the detergent used is suitable for high-efficiency (HE) washing machines.
• Use low-sudsing or HE detergent to minimize sudsing.

Step 4: Clean Detergent Dispenser

• Regularly clean the detergent dispenser to prevent residue buildup.
• Remove any clogs or blockages that may be impeding proper detergent flow.

Step 5: Run a Rinse Cycle

• Run an extra rinse cycle to help remove excess detergent and suds from the clothing and the machine.

Step 6: Inspect Drain System

• Check the drain pump and hoses for any blockages or restrictions.
• Ensure the drain hose is not kinked or obstructed to allow proper water drainage.

Step 7: Professional Assistance

• If the problem persists or if you doubt whether to proceed with further repairs, you may contact a professional.

Final Summary and Key Takeaways for the SUD Error Code

Resolving the SUD error code on a Maytag washing machine typically involves using the correct amount of detergent, cleaning the detergent dispenser, and making sure the washer drains properly. By following the steps in this guide, you can identify the cause of the excessive suds, clear the error, and prevent it from happening again.
