High efficiency washers were a genuine improvement. They use a fraction of the water of the machines they replaced, they are gentler on fabric, and they spin fast enough to cut drying time substantially.
They also changed the rules, and almost nobody was told. People kept using the same amount of detergent they always had, and the machines started smelling, and a decade of complaints followed that were really just a mismatch between old habits and new equipment.
The design change, and what follows from it
An old top loader filled the drum with water and sloshed clothes through it. That took a lot of water, and the surplus did something useful that nobody noticed: it diluted the detergent and it carried residue away.
A high efficiency machine uses a small amount of water and moves the clothes through it instead. Less water, more mechanical action, same cleaning.
The consequence is that the margin for error shrank. With a small amount of water, the concentration of detergent is far higher for the same dose, and there is much less spare water available to rinse it out.
So the two habits that were harmless before are now the cause of most complaints: using too much detergent, and using the wrong kind.
Use less than you think, and then less again
The cap on a detergent bottle is not a measuring device so much as a marketing one. The fill lines are frequently hard to read and generously placed.
For a high efficiency machine with a normal load, roughly two tablespoons of liquid detergent is the honest amount. Most people use three or four times that.
What excess does:
It does not rinse out. There is not enough water. The residue stays in the fabric, where it holds odor, stiffens texture, and attracts dirt faster on the next wear.
It coats the machine. The drum, the hoses, the dispenser channels, and the door seal all accumulate a film that becomes the food source for everything that grows in there.
It creates suds that interfere with cleaning. High efficiency machines rely on clothes rubbing against each other. Excess suds cushion that action, so more detergent actually washes worse.
It can trigger a longer cycle. Many machines detect suds and add rinses, which is the machine trying to correct your dosing.
Use the HE formulation as well. HE detergent is specifically low-sudsing, and standard detergent in a high efficiency machine produces exactly the problem described above.
The other three habits worth changing
Do not overload. The temptation is strong because the drums are large. But a high efficiency machine cleans through tumbling, and clothes packed tight cannot tumble. Fill it so you could still fit a hand in at the top.
Skip liquid fabric softener entirely. It is sticky by design, there is very little water to carry the excess away, and it coats the drum and seal along with the fabric. Half a cup of white vinegar in the rinse does the same job.
Run a hot load regularly. A machine that only ever sees cold water accumulates body oil, and there is not enough water volume to compensate. Towels warm or hot once a fortnight is enough.
Adjusting for what the machine cannot know
Most high efficiency machines weigh the load and decide how much water to use. That works well for ordinary loads and badly for two cases.
Bulky lightweight items. A comforter or a set of pillows weighs very little and absorbs a great deal of water. The machine reads the weight, adds a small amount of water, and the item never gets properly wet in the middle. If your machine has a bulky or bedding setting, that setting exists specifically to override the sensor.
Heavily soiled loads. The sensor measures weight, not dirt. Use the heavy or extra rinse option rather than expecting the machine to work it out.
A trick worth knowing: adding a quart of water to the drum before starting a bulky load helps the sensor read it correctly. Slightly awkward and it works.
The maintenance the manual assumes you are doing
Every high efficiency machine’s manual says to run a cleaning cycle monthly. Very few owners do.
Monthly: an empty cycle on the hottest setting with two cups of white vinegar, or the tub clean cycle with a machine cleaning tablet.
Monthly: wipe the door seal fold and pull out the detergent drawer.
Every three months: clear the drain pump filter behind the small panel at the bottom front.
Every load: leave the door and the drawer open afterward.
That last one is free and it is the most effective item on the list.
When the load genuinely needs more water
Some things want to be washed in a lot of water, and a high efficiency machine cannot provide it by design. Bedding that needs a real soak, a load of towels that has gone sour and needs stripping, anything with sand or grit in it, and any item large enough that the drum cannot tumble it freely.
The machines at our self-service laundry on Oram Street move considerably more water per cycle and have the drum size for a full comforter to move freely. For a strip wash specifically, water volume is the entire mechanism, since the whole point is carrying residue away rather than redistributing it within a small amount of water.
Our machines and the store are also cleaned daily, which is the maintenance schedule the manual for your machine at home is quietly assuming and not getting.
Our wash-dry-fold service covers everyday laundry if you would rather hand it over.
The short version
High efficiency machines use a fraction of the water, so the same dose of detergent is far more concentrated and there is much less spare water to rinse it away. Roughly two tablespoons of HE liquid for a normal load, which is a quarter of what most people use. Excess detergent does not rinse out, it coats the machine, and the suds cushion the tumbling the machine relies on to clean. Do not overload, skip liquid fabric softener, and run a warm or hot load regularly. Use the bulky setting for comforters, because the sensor reads weight rather than absorbency.
