A washing machine not filling with water is, most of the time, starved on the wall side of the machine rather than broken inside it. Start at the faucets: both the hot and the cold valve have to be open, and the two hoses between them and the washer must be free of kinks. If water reaches the machine but only a trickle gets in, the small mesh screens where the hoses meet the inlet valve are probably packed with sediment. Only after those three checks do the door lock, the lid switch, a badly placed drain hose, or the inlet valve itself come into question. The valve is the one part on this list that usually needs a technician.
This page covers a washer that will not fill, fills slowly, or starts filling and then gives up. A machine that does nothing at all when you press Start is a different fault, covered under washing machine won’t start. Every other symptom is listed in the washing machine troubleshooting guide.
Where the water is stopping, by likelihood
| Cause | Likelihood | Difficulty | What to do |
|---|---|---|---|
| Faucet closed, or only one of the two supply lines open | Very likely | Easy (no tools) | Open both the hot and the cold valve all the way; the washer needs both connected |
| Inlet hose kinked, pinched behind the machine, or frozen | Very likely | Easy (no tools) | Pull the washer forward a little and straighten the hoses; thaw a frozen hose with a warm towel |
| Inlet screens clogged with sediment or rust | Likely | Moderate | Shut both faucets, unscrew the hoses, clean the screens with a soft brush |
| Door not latched, or lid not seated on the lid switch | Likely | Easy (no tools) | Close the door firmly; on a top loader, check nothing is keeping the lid up |
| Drain hose too low or sitting in standing water, so the tub siphons out as it fills | Possible | Easy (no tools) | Snap the drain hose back into its holder with the end above water level |
| Weak household water pressure (other taps are weak too) | Possible | Professional recommended | Compare with a nearby faucet; if the whole house is weak, that is a plumber’s job |
| Failed water inlet valve, or rarely the control board that drives it | Possible | Professional recommended | A hum at the back with open faucets and clean screens points here; stop and book service |
Faucets, hoses, and screens: the checks that cost nothing
Whirlpool’s product help page on a washer that is not filling opens with the faucets, and it is blunt about it: “Both hot and cold water must be connected to the washer supply and turned on.” A washer with one line shut will stall on any cycle that calls for the missing temperature, and plenty of machines end up that way after a plumber’s visit or a well-meaning attempt to save on hot water. Turn each valve all the way open, not a half turn. Then look at the hoses. The same Whirlpool page lists kinks in the inlet hoses as a flow restriction, and a washer that got pushed back against the wall after a move is the classic case. LG adds a detail people forget in winter: if the supply valve or the hose runs along an outside wall and has frozen, wrap it in a warm towel rather than forcing anything.
If water clearly reaches the machine and it still fills at a trickle, the screens are next. Every inlet hose ends in a small mesh filter, either inside the hose fitting or on the back of the washer’s inlet valve, and sediment collects there over the years. Samsung’s support page is explicit about the order: shut the hot and cold taps before you touch the hose filters. Then unscrew the hoses with a bucket under them. Whirlpool says to clean the screens on the valve in place, with a brush and mild soapy water, without pulling them out or shifting their position. LG’s instruction for the hose-end type is to pull the filter out with pliers and scrub it with a toothbrush. Reconnect, open the faucets, and check the fittings for drips before running a cycle. Whirlpool’s page also notes that fill hoses should be replaced every five years, which is worth remembering if yours are stiff or bulging.
One more supply-side check is the house itself. Samsung notes that its 4C and 4E fill errors can be caused by poor water supply valves or water pressure, not only by the washer. Run a nearby faucet while the machine is trying to fill: if that tap is weak as well, the washer is the victim, not the cause, and the fix is on the plumbing side.
Door locks, lid switches, and a drain hose that empties the tub
A front loader will not open its inlet valve until the door is locked, and a top loader with a lid switch behaves the same way with the lid. Samsung’s first instruction for a machine that does not work is simply to “check that the door is tightly closed.” Push the door shut until you hear the latch, and on a top loader make sure a sock or a bottle of detergent is not propping the lid a fraction open. A lid that closes but no longer presses the switch is a part problem, and the won’t start page covers how that shows up.
The drain hose is the cause nobody suspects, because it has nothing to do with water coming in. If the hose end has slipped down into the standpipe or sits in standing water, the tub can siphon out as fast as the valve fills it, and the machine never reaches its level. LG’s fill-error page says to make sure the end of the drain hose is not submerged, and that if the hose has popped out of its holder, to snap it firmly back into place. That is a thirty-second fix on a washer that has been “not filling” for a week. On LG machines this whole family of faults shows as the IE water inlet code; on Samsung it is 4E or 4C, and Samsung says the machine then drains for three minutes with the power button inoperative, so wait that out before pressing anything.
What is left after all of that is the inlet valve, an electrically operated valve on the back of the machine with one solenoid per supply line. When the control board calls for water, the valve should click or hum and water should flow. A hum with nothing coming in, with both faucets open and both screens clean, is the valve not opening. A valve that lets water in when the machine is off is the opposite failure. Replacing it means opening the cabinet and working near the wiring, which on this site means a technician. The control board can fail to send the signal at all, but that is rare and it tends to come with other symptoms. A power cycle, unplugged for a few minutes the way your manual describes, is worth one try before you call.
Repair or Replace?
Most no-fill complaints are solved for free, with a faucet handle, a straightened hose, a cleaned screen, or a drain hose put back where it belongs. None of that is a reason to shop for a washer. A failed inlet valve is a modest repair on most machines and worth doing on anything that is otherwise sound, since the valve is an external, bolt-on part. The calculation changes if the technician finds the control board behind the symptom on an older machine, or if the fill fault is one of several problems arriving at once. The washing machine repair cost guide walks through where that line usually falls.
Frequently Asked Questions
How do you fix a washing machine that will not fill with water?
Open both faucets fully, straighten the inlet hoses, and close the door or lid firmly. If it still fills slowly, shut the faucets and clean the mesh screens at the hose ends and on the inlet valve. Check that the drain hose end is above water. What remains is the inlet valve, which is a job for a technician.
Why is my washer making a noise but not filling with water?
A hum or buzz from the back when the cycle calls for water is the inlet valve trying to open. With the faucets open and the screens clean, that noise with no water means the valve itself has failed and needs replacing.
Why is my washing machine just filling up with water and not washing?
That is a different fault. The fill side is working, so the faucets, hoses, and screens are fine. A washer that fills and then sits is usually waiting on the lid switch or door lock, or has a drive problem, and the won't start and not spinning pages on this site cover it.
How do I hard reset a washing machine?
Most manufacturers describe a power cycle: unplug the machine or switch off its breaker, wait a few minutes, and plug it back in. The exact wait and any button sequence vary by brand, so follow your manual or the reset guides on this site rather than a generic recipe.
Why does my washer fill so slowly?
Slow filling with open faucets almost always means clogged inlet screens or a partly closed valve. If a nearby tap is weak at the same time, the house pressure is the problem. A hose kinked behind the machine does the same thing.
Can the drain hose stop a washer from filling?
Yes. If the drain hose end sits in standing water or has slipped too far down the standpipe, water siphons out as the tub fills and the machine never reaches its level. LG lists this among its checks for a fill error. Put the hose back in its holder with the end above water.
These checks sort a supply problem from a part failure. They are not a substitute for a qualified technician once the fault is inside the cabinet, near the wiring, or comes with water on the floor.
