Amana Washer Not Filling with Water

Most Likely Cause#

When an Amana washer won't fill, the two leading causes tie at about 30% each — a supply valve that isn't fully open, and a failed water inlet valve — with scaled inlet screens close behind. Amana is built by Whirlpool on a deliberately simple platform, which is good news: the parts are interchangeable with Whirlpool equivalents, so they're cheap and easy to find. Start with the free check every time: both the hot and cold supply valves behind the machine must be fully open, and the washer needs at least 20 PSI of water pressure to fill properly. After plumbing work or a main shutoff, a valve is very often left half-closed.

Fault Map: Cause by What You See#

Free Checks First#

Before touching a tool, rule out the plumbing. Turn both wall supply valves fully counterclockwise to open, and check that neither fill hose kinked when the washer was pushed back. If your home pressure is marginal, a cheap gauge on a hose bib confirms you have the 20 PSI Amana needs — a whole-house pressure drop will starve the fill with nothing wrong at the machine. These cost nothing and catch a real share of "won't fill" calls.

The Inlet Valve and Screens#

Inlet valve. The water inlet valve is an electromechanical valve that opens when the control board signals it, and its solenoid coils wear out over time. Listen at the start of the fill: if you hear no click and no hum, the valve or its wiring has failed. On the NTW4516FW the valve sits at the rear where the hoses connect, and it replaces as a complete assembly. Because Amana rides on the Whirlpool platform, the same valve is often listed under a Whirlpool number for less.

Inlet screens. Small mesh screens in the valve ports and at the hose ends filter sediment, and hard-water scale gradually clogs them until flow drops. Shut both supply valves, disconnect the hoses with towels ready, and pull the screens out gently with needle-nose pliers. Soak them in white vinegar for about 30 minutes, scrub with an old toothbrush, and reinstall — clean the hose-end screens too, since either can throttle the fill.

The Pressure Switch#

The pressure switch tells the board when the tub is full. If it fails stuck in the "full" position, the board believes the tub already has water and never opens the inlet valve — so the machine sits dry with no fill. On Amana models the switch connects to the tub through a small air hose, so before condemning the switch, check that hose isn't kinked, cracked, or popped off its port, since a disconnected air line fakes a "full" reading just as convincingly as a bad switch.

Step-by-Step#

1. Cut power at the breaker before servicing.
2. Find the exact model on the serial plate — the NTW4516FW, NTW4519JW, and NFW5800HW differ in layout.
3. Open both supply valves fully and check the hoses for kinks.
4. Listen for the inlet valve's click and hum at fill; silence points at the valve.
5. If the valve and supply are good, clean the screens, then check the pressure-switch air hose.

Cost and Repair-or-Replace#

This is one of the cheaper washer repairs. Opening a valve or clearing a kink is free, cleaning the inlet screens costs only a little vinegar, and the inlet valve and pressure switch are inexpensive parts — cheaper still when you order them under the Whirlpool number rather than the Amana label. Because the machine is a simple, well-supported Whirlpool underneath, it's essentially always worth fixing over replacing rather than scrapping a washer over a ten-dollar screen or a closed valve. If it still won't fill after the free checks, book an EasyBear technician and we'll bring the inlet valve and pressure switch.
