Direct answer: A Whirlpool washer that keeps draining is most often siphoning through a drain hose set too deep or too low, or it is being told the tub is still full because the water-level sensing path is blocked or disconnected.
Most likely: Start with the drain hose position and standpipe setup. If the hose is installed wrong, the washer can keep pulling water out and act like it never finishes filling or rinsing.
First pin down the pattern: is the washer actively pumping water out with the drain pump running, or is water just slipping out on its own while the machine tries to fill? Those look similar from across the room, but they send you in two different directions. Reality check: a lot of 'bad washer' calls turn out to be a drain hose shoved too far into the standpipe. Common wrong move: replacing the drain pump because you hear water moving, when the machine is actually siphoning and the pump is fine.
Don’t start with: Do not start by ordering a control board. On this symptom, hose routing and pressure-sensing issues are far more common than an electronic failure.
You hear water entering, but the tub never seems to hold much. Water may be flowing into the standpipe at the same time.
Start here: Go straight to the drain hose height, insertion depth, and standpipe check.
You hear the pump motor humming or rushing even after the tub looks empty.
Start here: Check for cancel/drain mode first, then inspect the water-level pressure hose path.
The cycle starts normally, but the machine acts like it still has too much water or never reached the right level.
Start here: Inspect the pressure hose and air dome area for soap sludge or a loose connection.
Bulky loads, extra detergent, or a pushed-back machine seem to make it worse.
Start here: Look for a kinked or over-inserted drain hose and heavy suds before assuming a failed part.
This is the most common cause when the washer seems to fill and drain at the same time. If the hose is too low, sealed into the standpipe, or shoved in too far, gravity can pull water out continuously.
Quick check: With the washer filling, listen for water running into the house drain without the drain pump's stronger motor sound. Check that the drain hose has an air gap and is not buried deep in the standpipe.
If the drain pump is clearly running the whole time, the control may be stuck in a drain routine from a canceled cycle, a glitch, or a lid/door state issue.
Quick check: Cancel the cycle, unplug the washer for a few minutes, then restart a normal cycle and listen for whether the pump immediately comes back on.
The washer decides when to stop filling and when to drain based on water-level sensing. If the small pressure hose is clogged with residue, split, or popped off, the control can get bad level information.
Quick check: Unplug the washer, remove the access panel as needed, and inspect the small hose running from the tub air dome area to the water-level switch or sensor for kinks, soap buildup, or a loose fit.
Once the hose and drain setup check out, a bad level-sensing component becomes more likely. The machine may keep draining because it never gets a believable tub-level signal.
Quick check: Only suspect this after the drain hose setup is correct and the pressure hose is intact, clear, and firmly connected.
You need to know whether the washer is pumping water out on purpose or whether water is just being pulled out through the drain hose. That one observation saves a lot of wasted time.
Next move: You now know which path to follow instead of guessing at parts. If you cannot tell by sound alone, pull the washer out enough to watch the drain hose and standpipe while the cycle starts.
What to conclude: Water leaving without pump noise points to drain hose setup. Continuous pump noise points to a stuck drain command or bad water-level feedback.
A bad drain hose setup is the fastest, safest fix and the most common reason a washer keeps draining while filling.
Next move: If the tub now holds water normally and the cycle advances, the problem was siphoning and you are done. If the pump still runs when it should not, or the washer still acts like the tub level is wrong, keep going.
What to conclude: A corrected hose setup that fixes the issue confirms the washer itself was not the main problem.
Some washers get stuck in a drain routine after a canceled cycle, power glitch, or incomplete lid or door state. This is a quick check before opening the cabinet.
Next move: If the washer fills and runs normally after the reset, the issue was likely a temporary control hang-up. If the pump still runs right away or the washer returns to draining after a brief fill, inspect the water-level sensing path next.
When the washer cannot read tub level correctly, it may keep draining or refuse to move on. The small pressure hose is a common trouble spot and often fails before the sensor itself.
Next move: If the washer now fills to a normal level and stops draining, the sensing path was blocked or leaking air. If the hose is sound, clear, and tight but the washer still keeps draining, the level-sensing component is the stronger suspect.
Once the drain setup is correct, the reset did not help, and the pressure hose path is intact and clear, the remaining likely fix is the washer water-level switch or pressure sensor. If the pump itself is running loudly, leaking, or not moving water correctly during other cycles, the drain pump can also be a separate confirmed repair.
A good result: A normal fill, wash, and timed drain confirms you fixed the right problem.
If not: If the hose setup and sensing parts check out but the washer still commands nonstop draining, professional diagnosis is the smart next move because control faults and wiring issues are now higher on the list.
What to conclude: By this point you have ruled out the common installation issue and the usual sensing failure, so any remaining fault is less common and less certain.

Most of the time the drain hose is siphoning. The hose may be too low, pushed too far into the standpipe, or installed in a way that seals the drain opening and lets gravity pull water out as fast as it comes in.
Stand by the washer during fill. Siphoning sounds like water slipping into the drain, while a running drain pump has a stronger steady motor hum from the washer itself. If water is leaving without that pump sound, start with hose setup.
It can contribute. Heavy suds can confuse water-level sensing and leave residue in the pressure hose or air dome area. It is usually not the only problem, but it can make an existing sensing issue show up more often.
Not usually. If the washer is draining while filling, the pump is often innocent and the real issue is siphoning. The pump becomes a stronger suspect when it is clearly running nonstop, sounds rough, leaks, or also fails normal drain performance.
After you have corrected the drain hose setup and confirmed the washer pressure hose is connected, clear, and not leaking air. If the washer still acts like it never knows the right water level, the switch or sensor moves up the list.
Not until you fix the cause. A siphoning washer wastes water and can overflow a standpipe, and a washer stuck in drain mode can overwork the pump. It is better to correct the hose setup or sensing problem first.
