The Short Answer
An Amana top-loader stuck on “sensing” is failing one of its pre-wash checks, and three parts account for nearly all cases: the lid lock (must click shut and confirm electrically), the shifter assembly under the tub (must find the basket's position and report it), and the water inlet valve (must actually deliver water when asked). One sixty-second unplug is a fair first try; after that, the clicking, humming, or dry silence tells a technician exactly which suspect to charge.
What “Sensing” Actually Does
When you press start, an Amana top-loader — built on Whirlpool's vertical modular platform — runs a quiet pre-flight routine: lock the lid and confirm it, jog the basket to measure the load, and open the valve to begin the fill. The “sensing” light simply reports that this checklist is running. A healthy machine passes through it in a couple of minutes; a machine stuck there is repeating a step that keeps failing, like a pilot who can't get one gauge to read green. The good news: only three gauges matter.
Suspect One: The Lid Lock
Nothing proceeds until the lid is locked and the board believes it. Close the lid and listen: a firm click followed by a steady lock light is a pass. A click with a flashing lid-lock light means the mechanical latch caught but the electrical confirmation never arrived — the switch inside the lock has failed, and the washer will wait on sensing until the end of time. It is among the cheapest, fastest repairs our washer technicians perform, and the single most common answer to this complaint.
“A washer stuck on sensing has already done the diagnosis — it's been repeating the failed test for twenty minutes. Our job is mostly to listen.”

Suspect Two: The Shifter
Beneath the tub, the shifter assembly swaps the drive between agitate and spin and tells the control board where the basket sits, via a small optical sensor. Age fogs the sensor and wears the actuator, and the board — never receiving its “in position” signal — jogs the motor, waits, and jogs again: the soft, rhythmic clicking and humming owners describe from underneath the machine. The washer may even fill and then freeze. The shifter is an inexpensive part, and replacing it also cures the sibling symptom of washing normally but never handing off to spin.
Suspect Three: The Fill Valve
Sensing also expects water on schedule, and a washer that sits bone dry while the light blinks is waiting for a fill that never comes. Check the human causes first — taps fully open, hoses unkinked, and the little filter screens where hoses meet the valve (Alberta hard water silts them shut reliably). If water pressure arrives at the machine but never enters the tub, the inlet valve's solenoids have retired. Like its co-conspirators, it's a stocked, same-day part — and the full family playbook for these Whirlpool-built top-loaders lives in our Whirlpool washer bulletin.
Sensing Questions
How do I reset an Amana washer stuck on sensing?
Unplug it for sixty seconds, plug it back in, and start a small, empty cycle. That reboots the control and gives the machine one clean chance to pass its checks. If it locks the lid, hums briefly, and parks on “sensing” again, the fault is physical — a lid lock that isn’t confirming, a shifter that can’t find its position, or a valve that isn’t filling — and no quantity of resets changes physics.
What is the shifter on an Amana washer?
The shifter assembly sits under the tub and swaps the drive between agitation and spin, reporting the basket’s position to the control board through an optical sensor. When the sensor window fogs or the actuator wears, the board never gets the “ready” signal and waits on sensing forever — often clicking softly as it retries. It’s the most common single cause of the stuck-on-sensing complaint and an inexpensive, same-day part.
Why does my Amana washer click but never start washing?
That rhythmic clicking is the machine retrying a check that keeps failing — usually the lid lock striking without confirming, or the shifter actuator hunting for position. Listen to where the click comes from: lid area points at the lock, underneath points at the shifter. Either way the washer has already diagnosed itself; the click is just it asking for the part.
