Why won't my Whirlpool washer switch from filling to actually washing?

Yes, there is still a pressure tube in there, but on these digital Whirlpools the pressure switch isn't a separate mechanical clicker anymore—it's an electronic transducer soldered right onto the main control board. A small clear tube runs from that board down to an air dome on the bottom of the outer tub. If that tube slipped off, developed a pinhole, or got pinched during assembly, the board never senses the pressure rising. It assumes the tub is completely dry, so the valves just stay open indefinitely waiting for a signal that never arrives. When it does the exact opposite and barely trickles in two inches of water, that's usually either a corrupted calibration file or detergent suds backing up into the air trap. The auto-dispensers on these models are notorious for overdosing concentrated HE soap. If excessive suds get pushed up that pressure line, they dry into a gummy film and trap pressure against the transducer, tricking the computer into thinking the tub is already full. Before you take anything apart, force a **calibration cycle**. Put the machine in standby with all lights off. Turn the cycle knob one full click counter-clockwise to clear it, then do three clicks clockwise, one click counter-clockwise, and one click clockwise—all within about three seconds. When all the status lights start blinking, turn the knob until only the Rinse LED is lit, then press Start. Let it run completely uninterrupted for about four minutes while it recalibrates the tub weight and pressure zero-point.

If the calibration fails or aborts with an error, stop messing with it and call Whirlpool for warranty service. At four months old, you're well within your one-year factory window. Whirlpool's quality control on these top loaders has been pretty rough lately, and you shouldn't have to foot the bill for a bad main board or cracked pressure line on a practically brand-new machine.

This modern computerized junk drives me up the wall. You used to pull the knob on an old direct-drive, hear the mechanical timer click along, and the tub filled til the physical switch went thump. Simple. No secret handshake codes with the dial just to convince a circuit board to do its job. While you're dealing with warranty, stop using that auto-dispenser entirely. Go back to tossing two tablespoons of regular powder straight into the tub before loading, like we did for forty years. Half these modern headaches started when engineers decided a washer needed an onboard computer just to pour soap.

Check your drain hose depth before you tear your hair out. If whoever hooked it up shoved that corrugated hose more than four or five inches down the standpipe without the plastic anti-siphon bracket, it's constantly siphoning out the back while it fills. The tub never builds head pressure, so the inlet valves just run indefinitely.

Pull your fault codes in that service mode. If you see an F8E1 for long fill, look down the pipe while it's running to see if water is trickling out. If the plumbing is solid, you're probaly looking at a dead turbine in the W11220230 valve assembly not counting pulses.

Wait, does yours have that slow-close glass lid where you can actualy watch the whole wash cycle?? I just bought my very first house and was literally staring at that exact machine at the store last weekend, the giant glass top looks so cool, like a spaceship!

Quick question though since you have one—does that window actually stay clean long-term or does the underside get all permanently streaky and scratched up from detergent splashes? I'm totally obsessed with being able to see inside while it runs, but now I'm super curious if you can even see trough it after a few months!

Honestly, cut your losses and see if the store will let you exchange it. If you want a top loader that never pulls this sensor nonsense and actualy cleans your clothes, buy a Speed Queen TC5. We went trough two modern Whirlpool and Samsung units before giving up and getting the TC5003WN. Zero touchscreens, no finicky auto-dispensers to gum up lines, and it actually fills the tub with hot water when you tell it to. Total commercial-grade tank that will easily outlive three of those glass-lid gimmicks.
