Can You Use Regular Detergent In A He Washer Troubleshooting Sud Errors

High-efficiency (HE) washing machines have become standard in modern homes due to their water and energy savings. However, they operate differently from traditional washers—especially when it comes to detergent. Using the wrong type can trigger persistent suds errors, reduce cleaning performance, and even cause long-term mechanical issues. Many homeowners unknowingly pour regular detergent into HE machines, unaware of the consequences. Understanding the science behind HE compatibility and learning how to respond when suds errors occur is essential for appliance longevity and laundry success.

Why HE Washers Are Different

HE washers use significantly less water than conventional top-loading machines. They rely on tumbling action rather than full immersion to clean clothes, which means foam and excess suds interfere with the wash cycle. Regular detergents are formulated to generate high levels of suds in large volumes of water. In an HE machine’s low-water environment, this creates a surplus of bubbles that the system cannot effectively rinse away.

The excess suds reduce cleaning efficiency by cushioning clothes instead of allowing them to rub against each other. More critically, they can trap dirt and bacteria, leading to residue buildup. Over time, this residue accumulates inside hoses, pumps, and seals, fostering mold and mildew. The machine's sensors detect abnormal suds levels and display error codes such as “Sud,” “SD,” or “E22” (depending on brand), halting the cycle to prevent overflow or mechanical strain.

“Using non-HE detergent in a high-efficiency washer is like putting diesel fuel in a gasoline engine—it might run for a while, but internal damage is inevitable.” — David Lin, Appliance Engineer at Midwest Home Systems

Understanding Suds Errors: Causes and Implications

A suds error is not just a minor inconvenience; it signals that your washer is struggling to manage foam levels. These errors typically appear mid-cycle and may cause the machine to extend drain times, skip spin cycles, or shut down entirely. Common suds-related error codes include:

• Sud or SD – Samsung, Whirlpool, Kenmore
• E22 – Bosch, Thermador
• F05 – LG
• Err – GE Profile models

The root causes go beyond simply using regular detergent. Other contributors include:

• Overuse of HE detergent (even if labeled “HE-safe”)
• Detergent pods that dissolve too slowly or incompletely
• Residue buildup from repeated low-suds-clearing cycles
• Use of fabric softeners or bleach additives that interact poorly with detergent chemistry

Tip: If your washer displays a suds error, do not restart the cycle immediately. Allow time for the foam to dissipate naturally or run a rinse-only cycle first.

Step-by-Step Guide to Troubleshooting Suds Errors

When your HE washer shows a suds error, follow this structured approach to resolve the issue safely and effectively.

1. Pause and unplug the machine. Safety first—disconnect power to avoid electrical hazards during manual intervention.
2. Wait 30–60 minutes. Let the suds settle naturally. Rushing into draining can cause overflow.
3. Run a Rinse/Spin cycle without detergent. This helps flush out remaining foam. Repeat if necessary.
4. Inspect the detergent drawer. Remove and clean it thoroughly under warm water to eliminate clogs or residue.
5. Check the drain pump filter. Located at the front lower panel, this filter can trap soapy debris. Clean according to the user manual.
6. Run a maintenance wash. Use a dedicated washer cleaner (like Affresh or Tide Washer Maintenance Cleaner) on the hottest setting monthly to prevent buildup.
7. Verify detergent type and dosage. Switch to HE-formulated detergent and measure precisely—most loads require only 1–2 tablespoons.

After completing these steps, resume normal operation. If the error recurs frequently despite correct detergent use, consider internal inspection by a technician, as residual soap scum may be affecting sensor function.

Regular Detergent vs. HE Detergent: A Practical Comparison

Not all detergents are created equal. The formulation differences between regular and HE detergents are critical for machine compatibility.

Feature	Regular Detergent	HE Detergent
Foam Production	High suds, designed for agitators	Low-suds, optimized for tumbling action
Water Usage Compatibility	Requires 25+ gallons per load	Designed for 10–15 gallons per load
Cleaning Mechanism	Relies on suds suspension	Enzyme-rich, fast-dissolving formula
Rinsing Efficiency	Poor in low-water systems	Engineered for complete rinse-out
Machine Safety	Risk of sensor errors and pump strain	Safe for HE components and sensors
Cost per Load	Often cheaper upfront	Slightly higher, but prevents costly repairs

While regular detergent may seem more economical, its misuse in HE machines can lead to expensive service calls or premature replacement. HE detergents are specifically engineered to dissolve quickly, minimize foam, and deliver effective cleaning in reduced water environments.

Real-Life Example: A Costly Mistake in Suburban Laundry Room

In 2022, Sarah M., a homeowner in Columbus, Ohio, began noticing her Samsung FlexWash displaying “Sud” errors every few weeks. Assuming it was a glitch, she reset the machine and continued using her favorite liquid detergent—a popular supermarket brand not labeled for HE use. Over six months, the washer’s spin cycle weakened, clothes emerged damp, and a musty odor developed.

She called a technician who found thick soap residue coating the drum seal and clogging the drain pump. The cost of repair: $287 for parts and labor. After switching to HE detergent and implementing monthly cleaning cycles, her machine returned to optimal performance. “I had no idea one small choice could cause so much damage,” Sarah said. “Now I read labels carefully—and I tell everyone in my mom’s group chat to do the same.”

Best Practices for Preventing Suds Errors

Prevention is far more effective than troubleshooting. Adopt these habits to protect your HE washer and ensure consistent results.

Tip: Measure detergent carefully—even HE brands can cause suds if over-poured. Use the cap’s markings or a tablespoon for accuracy.

• Always choose HE-labeled detergents. Look for the “HE” symbol on packaging.
• Avoid double-dosing for “extra dirty” loads. Instead, pre-treat stains or use a soil-intensive cycle.
• Don’t overload the dispenser. Excess detergent sits unused and leaks into the next cycle.
• Use pods with caution. Some brands release detergent too late in the cycle, increasing suds risk.
• Never mix detergent types. Combining powders, liquids, and pods can create unpredictable reactions.
• Keep the washer door ajar when not in use. This promotes airflow and reduces moisture buildup that interacts with soap residue.

Monthly Washer Maintenance Checklist

Stay ahead of suds problems with routine care.

1. Run a hot water cycle with washer cleaner or 2 cups of white vinegar.
2. Clean the detergent drawer weekly with warm, soapy water.
3. Wipe the door gasket (especially front-loaders) to remove lint and moisture.
4. Inspect hoses annually for cracks or bulges.
5. Ensure the floor is level—vibration increases wear and affects drainage.

Frequently Asked Questions

Can I ever use regular detergent in an emergency?

In a true emergency, a very small amount (1 teaspoon) of regular detergent *might* work in a single load, but it's risky. Even minimal suds can accumulate over time. A better alternative is to hand-wash heavily soiled items or borrow detergent from a neighbor. Consistently using non-HE detergent voids most manufacturer warranties.

Do HE detergents clean as well as regular ones?

Yes—and often better in HE machines. HE detergents contain concentrated enzymes and surfactants designed to work efficiently in low-water conditions. They target soils directly rather than relying on suds to suspend grime. Independent tests by Consumer Reports show HE formulas outperform regular detergents in HE washers across stain removal and fabric care metrics.

Why does my HE washer still have suds after switching detergents?

Residual soap buildup from past use can linger in hoses, pumps, and the outer drum. Run 2–3 cleaning cycles with a dedicated washer cleaner on the hottest setting. Avoid using vinegar and baking soda together—they neutralize each other. Stick to one cleaner per cycle.

Conclusion: Protect Your Investment with the Right Choices

Your HE washer is a precision appliance designed for efficiency, longevity, and performance—but only when used correctly. Using regular detergent may seem harmless at first, but the resulting suds errors are warning signs of deeper issues. By choosing HE-approved products, measuring doses accurately, and maintaining your machine regularly, you prevent unnecessary wear, avoid repair costs, and keep clothes cleaner.

The shift to HE-compatible laundry habits doesn’t require drastic changes—just awareness and consistency. Start today by checking your current detergent label. If it lacks the HE designation, make the switch. Your washer, your clothes, and your utility bill will thank you.
