LG washing machines are known for their efficiency and modern features, but even the most reliable machines can display error codes from time to time. One common code is “Sud”, which signals that there are too many suds in the washer. Understanding this error, why it happens, and how to fix it can help you get your laundry back on track quickly.

What the “Sud” Error Means

When your LG washer shows the Sud error, it essentially means the machine has detected excessive foam during the wash cycle. This triggers the washer to pause or temporarily stop to prevent overflow or damage to internal components.

Typical signs include:

• Washer stops mid-cycle and displays Sud on the screen.
• Excessive foam spilling over the drum.
• Extended cycle times as the washer tries to clear the suds automatically.

Why This Error Happens

The Sud error usually occurs due to using too much detergent or using the wrong type of detergent. Factors contributing to this problem include:

• Using standard detergent instead of high-efficiency (HE) detergent.
• Overfilling the detergent compartment.
• Washing very small loads with a normal or large dose of detergent.
• Hard water causing certain detergents to foam excessively.

How to Fix the Sud Error Yourself

Fortunately, the Sud error is one of the easier LG washer issues to handle without professional help.

DIY Fix Steps:

1. Wait It Out: The simplest approach is to let the washer run its anti-suds routine. The machine will drain water and reduce suds naturally before resuming the cycle.
2. Manual Drain Option: If waiting isn’t practical, you can manually remove the water. Most LG washers have a drain or spin-only option to help clear suds quickly. Check your user manual for specifics.
3. Clean Residual Detergent: Once the cycle is complete, wipe down the drum and detergent drawer to remove leftover foam and detergent residue.

By following these steps, you can get your washer back to normal operation and prevent potential damage caused by excessive suds.

Preventing the Sud Error in the Future

Avoiding the Sud error involves proper detergent use and a few simple habits:

• Always use HE detergent in an LG washer. HE detergents are designed to produce less foam and work efficiently with high-efficiency machines.
• Follow the recommended detergent dosage on the product label. More detergent does not equal cleaner clothes.
• Avoid combining standard detergent with fabric softeners that may increase suds.
• Wash medium or small loads with proportionally less detergent to prevent excess foam.
• Occasionally run a clean washer cycle with no clothes and a small amount of vinegar or washer cleaner to remove residual detergent build-up.

Quick Troubleshooting Checklist

• Check that you’re using HE detergent.
• Verify detergent amounts are within recommended limits.
• Allow washer to automatically drain and clear suds.
• Manually drain water if needed.
• Clean drum and detergent drawer regularly to prevent residue buildup.

By understanding the Sud error and taking these preventive measures, you can enjoy smooth and efficient washing cycles without interruptions. LG washers are designed to handle suds carefully, and following these simple steps ensures your laundry stays on schedule.
