HE Detergent vs. Regular Detergent: Why It Matters
Most washers sold in the last decade or more are HE machines, and the detergent bottle matters more than it might seem. Here's what HE actually means, what happens when regular detergent goes into an HE machine anyway, and what to do about it.
Request ServiceWhat HE actually means
HE detergent is a low-sudsing formula made specifically for high-efficiency machines that use less water per cycle than older washers. Less water means less rinsing power, so the detergent has to produce fewer suds to begin with.
Why suds are the problem
Regular detergent is formulated for machines that use much more water, so it produces far more suds than an HE machine's lower water level can rinse away. That mismatch is the root of nearly every issue that follows from using the wrong detergent.
What excess suds can lead to
Three downstream effects
Suds lock
Excess suds can overflow the machine or strain the pump and motor, a condition sometimes called suds lock, since the extra foam interferes with normal tumbling and drainage.
Error codes
Many HE washers detect excessive suds automatically and stop mid-cycle to protect themselves. See Common Washer Error Codes for how Samsung's SUD code and similar codes on other brands work.
Poor rinsing & longer cycles
Even short of a full suds lock, excess foam interferes with the machine's tumbling action, which reduces stain removal and leaves detergent residue behind, sometimes with a lingering odor.
If it happens once
One accidental load of regular detergent in an HE machine doesn't typically cause lasting damage on its own. Cancelling the cycle, running an empty spin or drain cycle, and following up with a cold-water rinse cycle helps clear the excess suds before running another load.

Making it a habit, not an accident
The easiest way to avoid the issue entirely is checking the detergent bottle for an "HE" label before buying, and keeping a single labeled container near the machine so it's not easy to grab the wrong bottle out of habit.
When it's more than detergent
If suds, odor, or slow draining keep showing up even with the correct detergent and the right amount used consistently over several loads, the cause is more likely a buildup issue inside the machine or a mechanical one than a simple detergent mismatch, and it's worth having the machine looked at directly rather than continuing to troubleshoot detergent choice alone.
Questions
HE detergent questions
How do I know if my washer is HE?
Look for an "HE" label printed on the washer itself or in the owner's manual. Most front-load washers and many newer top-load models without a center agitator are HE machines.
Does using HE detergent in a non-HE washer cause problems?
Generally no. HE detergent works fine in a standard washer. It's specifically regular, high-sudsing detergent used in an HE machine that causes the oversudsing problem, not the other way around.
Does pod-style detergent count as HE?
Only if the packaging says so. Some pods are formulated as HE and safe for high-efficiency machines, while others use a standard formula, so checking the label matters just as much with pods as it does with liquid or powder detergent.
