An HE top load washer is not meant to fill. You will look into the drum mid-cycle, see damp laundry sitting above a shallow pool of water, and conclude the machine is broken — and it is working exactly as designed. The clothes are supposed to rub against each other rather than float, and the water level you can see is the whole efficiency gain you paid for.
Almost every complaint about these machines traces back to that one misunderstanding, and the complaints that follow from it — long cycles, aborted spins, residue on dark clothes, laundry that comes out stiff — are usually the owner correcting a machine that was not wrong. So this page does the mechanism first. If the machine is already in your house, the first three sections may save you a service call. If you are still shopping, they tell you what you are actually signing up for.

Why the drum looks almost dry and the machine is fine
Take the central post out of a top-loading tub and put a low disc in the floor instead, and you have changed what moves the laundry. There is no longer a fin dragging fabric past itself through deep water. Instead the disc rotates and rocks the load so that garments slide against each other, and that friction between wet fabric surfaces is what does the cleaning.
Friction between fabrics requires the fabrics to be touching. Fill the tub and they float apart, and the wash action stops working. So the machine deliberately adds only enough water to wet the load and let it move, which is why what you see through the lid is a damp heap rather than a bath. Whirlpool describes its version in exactly those terms: “the most striking difference in this washer is the low-water wash plate wash system. The washer automatically adjusts the water level to the load size; no water level selector is needed” (Whirlpool — low water level, washer).
The same page gives the loading instruction that follows from the mechanism, and it is the single most useful sentence available on this subject: load “items in loose heaps evenly around the wash plate”, and “leave the center of the wash plate uncovered for the best results.” Piling laundry on top of the disc stops it doing the one thing it exists to do. Almost nobody is told this, and it explains a large share of the “my HE washer doesn’t clean” reports on its own.
The format difference underneath all of this — post versus disc, and which breaks — has its own page at agitator vs impeller washer, and it is worth reading if you have not yet chosen between them.
An HE top load washer senses the load before it fills
Here is the sequence the machine runs, because knowing it removes most of the anxiety.
The lid closes and the drum moves the load briefly without water. That is the machine weighing and feeling the laundry — mass, and how it shifts. From that it calculates a water volume and a cycle length, then begins to fill. Whirlpool documents that the fill is not a single event: the control “will sense the load and determine if additional water is needed. Your washer may go through a series of small fills to get to the appropriate water level.” So a machine that fills, pauses, waits, and fills again is not hesitating. It is measuring.
Two consequences people read as faults. The first is a cycle time that changes after it has been displayed, because the estimate was made from the sensed load and gets revised as the machine learns more. LG documents the extreme version of this on its own machines: a wash cycle estimated at 30 minutes re-estimating to 1 hour 52 minutes once sensing detects that the laundry went in already damp and is therefore much heavier than it looks. Nothing is broken; the machine sized the cycle for a load twice the size.
The second is the spin. A tub with a sensed, shallow water level and a load that has redistributed itself during the wash can end up genuinely unbalanced, and the machine will not accelerate it. Samsung publishes what its control does about that: a Ur code means “the washer is going to try to add more water, try to balance the load, and then try the spin cycle again. This will extend the length of the cycle”, and — the sentence worth remembering — “a Ur code does not mean that there is an issue with your washer, it’s just there to tell you what’s happening” (Samsung — washer information and error codes).
The one fix to try before you call anyone
If the water level genuinely seems lower than it used to be — not lower than you expected, lower than it was a year ago — there is a documented procedure, and almost nobody knows about it.
Whirlpool states it plainly: “if you feel that the washer level is lower than when you first started using this washer, try running a Clean Washer cycle. This cycle re-calibrates the control and resets it to the factory-set water levels.” The same page recommends running it “approximately one time per month or every 30 cycles.”
Read that twice, because it changes what the tub-clean cycle is for. Most people think of it as a hygiene routine, and it is, but on these machines it is also a calibration reset for the water-level control. A monthly tub clean is therefore doing two jobs at once, and skipping it for a year means both go undone. What the cycle itself does and how to run it is on washer tub clean cycle explained.
That is the free fix, and it comes before any spending. If it does not change the fill level, the next suspect is the water-level pressure switch rather than the machine’s design — and that is a diagnosis, not a purchase.
HE detergent is not a marketing tier
This is the part where an owner can genuinely damage the wash, and it is a dosing problem rather than a product problem.
Low water means high detergent concentration. The same capful that disappears into a tub of water in an agitator machine is sitting in a fraction of that volume here, and the result is foam the machine then has to deal with. Excess suds cushion the load so the fabric-on-fabric friction stops working, lengthen the cycle, and show up as residue and streaking on dark clothes. Whirlpool’s wording covers both halves: “using non-HE detergent or more than the manufacturer’s recommended amount can cause excessive suds and poor cleaning performance.”
So two rules, in order of how often they are broken. Use a low-foaming HE formula — the difference is real and it is explained at HE vs regular detergent. Then dose for your water rather than for the cap, because water chemistry changes the requirement: Whirlpool notes on the same page that “if you have very soft water, you may need to use less detergent”, and detergent itself does part of the work of softening hard water.
And do not use the dose as a substitute for loading properly. Two-thirds of the drum is the working figure on most machines, the empty third is what makes the wash action possible, and the detail is on how full should a washing machine be.
HE top-loaders worth shortlisting
Three, and I am going to be blunt about the state of this category on Amazon: the low-water top-loader is poorly served here, and the impeller subtype worst of all — the one listing that named an impeller in its own title is no longer buyable at all. Most listings are third-party appliance dealers, stock moves, and one of the three below is scarce rather than freely available. Most Americans buy these from a big-box retailer or a local dealer, and that is simply the reality of the channel.
LG WT8400CB 5.5 cu. ft. mega capacity — the one whose load sensing is a published feature rather than a footnote. AI Sensing is LG’s name for the sequence this page has just described: the control reads load size, fabric type and soil level, then sets the water level, the wash time and the settings from what it found, which is why there is no water-level dial to turn. EasyUnload widens the drum opening, which on the deepest basket here is a real ergonomic feature rather than a badge — reaching to the bottom of 5.5 cubic feet for the last sock is the one complaint a big top-loader reliably earns. It is smart-connected, so remote start and end-of-cycle alerts go to a phone rather than being guessed at. The footprint is the standard one: 27 inches wide, 28.4 deep, 43 tall, 130 lb, which is short enough to clear most wall cabinets. Two honest notes, and the second is the reason it is not described as an impeller machine above: it is sold by a third-party appliance dealer rather than Amazon, and the listing does not state whether the wash action is a low plate or a post. If the impeller subtype specifically is why you are here, confirm it against LG’s own specification for this model number before ordering.
Samsung WA50R5200AW 4.5 cu. ft. — the washer-only alternative. A plain, well-established 4.5 cubic foot HE top-loader at 44.35 inches tall and 27.5 wide, which is the one to look at if you want a plain washer from a plain listing rather than a connected machine or a pair. The honest notes are substantial: the listing carries almost no feature detail, it is sold by a third-party appliance dealer rather than Amazon, it sits well down the category ranking, and it is scarce stock. Buy it on the format and the footprint, and read the model’s own manual for the cycle list rather than trusting the listing.
Samsung WA44A320KIT1 — an HE top-loader and matching dryer, sold as a pair. Stating the obvious first, because the listing title does not make it obvious: this is two appliances, a 4.5 cubic foot HE top-load washer and a 7.4 cubic foot electric dryer, not a washer on its own. If you are replacing both at once that is an advantage; if you only need the washer it is the wrong purchase. It is Wi-Fi connected through SmartThings with the one genuinely useful connected feature — the listing says it “automatically detects and communicates issues through the SmartThings app” — and it ships with the dryer vent, power cable and two water hoses. It is in stock rather than scarce, which is why it is here. Two things to note: it is sold by a third-party dealer, and the “12-Month CPS Protection Plan” bundled with it is a third-party protection plan, not a Samsung warranty extension.
When an impeller is the wrong answer
If your laundry is genuinely dirty rather than just worn. Grit, mud, grease and sawdust need water to carry them away, and this is the format engineered to use the least of it. An agitator machine with a deep-fill option is the better tool, and it is cheaper. That is the honest recommendation even though it points away from this page.
If nobody in the house will load it correctly. The whole mechanism depends on loose heaps around an uncovered wash plate. In a household where laundry gets crammed in, an impeller machine under-performs in a way an agitator machine tolerates, and you will spend three years believing you bought a bad washer.
If you are not prepared to switch detergent and dose. Non-HE detergent in one of these produces poor cleaning and long cycles by a documented mechanism. If the detergent in the cupboard is not changing, neither should the machine.
If what you actually want is efficiency. Then look at the certification numbers rather than the marketing. ENERGY STAR requires IMEF ≥ 2.06 and IWF ≤ 4.3 for a certified top-loader over 2.5 cubic feet, against 2.76 and 3.2 for a front-loader (ENERGY STAR key product criteria). Lower IWF is better. An HE top-loader is far more efficient than an agitator machine and still some way behind a front-loader, and the rules say so.
FAQ
Is an HE top load washer supposed to fill with water?
Not to the top, no. It adds only enough water to wet the load and let the garments rub against each other, because floating clothes cannot create the friction that does the washing. A shallow pool under a damp heap of laundry is the normal picture.
Why does my HE top loader not cover the clothes with water?
Because covering them would stop it cleaning. Whirlpool states that the washer “automatically adjusts the water level to the load size” and that no water level selector is needed, which is the design rather than a fault.
Why does the cycle time keep changing?
The displayed time is an estimate made from the load the machine sensed, and it gets revised as the machine learns more — particularly if the laundry went in damp and is therefore heavier than it appears. LG documents a 30-minute wash re-estimating to 1 hour 52 minutes for exactly that reason.
What does a Ur code mean on a top loader?
That the load is unbalanced and the machine is handling it. Samsung’s own wording is that the washer will add more water, try to balance the load and retry the spin, which extends the cycle, and that the code “does not mean that there is an issue with your washer.”
Can I add more water to an HE top load washer?
On most impeller models there is no water-level selector to turn, which is Whirlpool’s own point. Some machines offer a water-plus or deep-fill option on specific cycles. If the level genuinely seems to have fallen over time, run a Clean Washer cycle — Whirlpool says it re-calibrates the control to the factory water levels.
Do HE top loaders tangle clothes?
More than an agitator in one specific way: the load is moving against itself in a small volume of water for a long cycle, so long items can rope together. Loading in loose heaps around the plate rather than folded bundles is what reduces it.
How often should I run the tub clean cycle on one of these?
Whirlpool says approximately once a month or every 30 cycles. On these machines it does double duty, because the same cycle re-calibrates the water-level control, so skipping it costs you hygiene and fill accuracy at once.
Trust the sensor, change the detergent
If you already own one of these machines, do two things before you conclude it is faulty: run a tub clean to reset the water calibration, and reload it the way the manufacturer describes — loose heaps around the plate, centre of the plate uncovered. That combination fixes a surprising share of the complaints this format attracts, and neither costs anything.
If you are buying, buy it for what it is: the efficient top-loader, the one that sizes its own fill and wants a low dose of HE detergent and a sensible load. Buy an agitator machine instead if your washing is genuinely filthy, and if a clear basket with no post to wrap a sheet around is the specific thing you want, confirm the wash action against the maker’s specification rather than the listing — that detail has become hard to buy on this channel. The water you are not seeing is the point of the machine, not a defect in it.
