When no water enters the drum, the fault is on the supply side far more often than inside the machine — and that is genuinely good news, because most of the supply side costs nothing to fix.
The fill path runs in one direction: wall valve → supply hose → inlet screens → inlet valve → tub. Five stages. Four of them are behind the machine where you can reach them with nothing more specialised than a towel and a bucket. Only the last one, the inlet valve, is a part you would have to buy — and it is the least likely of the five to be the problem.
There is one question that cuts this diagnosis in half before you touch anything: does it fail on both temperatures, or just one? Hot and cold each have their own hose, their own screen, and their own valve solenoid. If cold works and hot doesn’t, you have just eliminated two-thirds of the possible causes and you know exactly which side to look at. Most people never ask, and end up checking everything twice.
This guide is for a washing machine not filling with water at all — no meaningful amount, not even a steady trickle. If water enters but far too slowly, see washing machine fills too slowly — same path, different threshold. If it fills then empties straight away, see washing machine fills then drains.
Is the washing machine not filling with water, or did it never start?
Everything below this section assumes the machine asked for water and did not get it. There is a second situation that looks identical from across the room and has nothing to do with your plumbing: the machine never began the fill step at all, because it is still waiting for permission to start.
The distinction is easy to make and it saves you disconnecting hoses for nothing. A machine that is trying to fill has begun its cycle — the display counts, the drum may turn briefly to sense the load, and you will usually hear the inlet valve click as it opens. A machine that never started is silent in a different way: no valve click, no drum movement, and the timer is not moving.
The most common reason for the second case is a door or lid that is closed but not latched. No washer will admit water until it has confirmed the door is locked, because an unlocked door and a filling drum is a flood. The gap between “shut” and “locked” is small enough that you cannot see it, which is exactly why this gets misread as a water fault. Samsung’s whole door family carries this meaning — “the door is not detected as closed and locked” (Samsung washing machine information and error codes).
Press the door firmly until it clicks and start the cycle again. On a top-loader, check that nothing is sitting under the lid edge and that the lid closes fully flat. If a garment strap or a sleeve is caught in the seal, the latch cannot engage and the machine will sit there indefinitely without ever calling for water.
| What you notice | Which problem you have |
|---|---|
| Timer counting, drum turning, a click from the valve | It is trying to fill — continue below |
| Timer frozen, no click, no drum movement | It never started — door, lid or start permission |
| A door or lid code on the display | It never started — see door locked after cycle |
| Display lit but Start does nothing at all | Start permission — see power but won’t start |
The fill path, stage by stage, and what fails at each
- The cycle never started — a door or lid closed but not latched, so the machine is still waiting for permission and has not asked for water yet. Ruled out in the section above.
- A supply valve closed or barely open. The most common cause and the fastest to rule out. A valve cracked a quarter of the way open passes enough water to look on if you glance at it, while delivering nothing usable to a machine expecting mains pressure. Plumbers close these during other work and forget to fully reopen them constantly.
- A kinked, crushed or frozen supply hose. Here is the part people find genuinely surprising: vibration during spin gradually walks a machine backwards until it pinches its own hoses against the wall. That is why a machine can fill perfectly for two years and then fail one morning with nothing having changed — nothing did change, except a few millimetres a week for two years.
- Clogged inlet screens — small mesh filters where the hoses meet the machine. Sediment, rust, sand and scale collect there and worsen gradually, so the failure creeps rather than arrives. In hard-water areas this is maintenance rather than a fault.
- A flood-safe or auto-shutoff hose that has tripped. These have a check valve that latches shut after a sudden surge and stays shut until manually reset. Genuinely easy to miss, because the hose looks completely normal from outside.
- Crossed hot and cold connections, which on many machines throws a fill-related code rather than simply filling from the wrong tap.
- A failed inlet valve — the electrically operated valve inside the machine that admits water.
- A pressure or water-level sensor misreporting the tub as already full, so the control never calls for water at all.
What to know before you disconnect a hose
- Model number and form factor.
- Any code shown, exactly as displayed.
- Whether it’s both temperatures or one. As above — this single answer eliminates most of the list.
- Whether any water enters at all, even a trickle. None at all and a slow trickle lead different directions.
- Recent history — a plumbing repair, a cold snap, the machine being moved, a new flood-safe hose fitted. Nearly every sudden fill failure has one of these behind it.
Normal behaviour vs an actual fault
Two normal behaviours get reported as faults here more than anything else. Modern machines use far less water than older ones, and add it in stages rather than one visible flood — a level that looks alarmingly low on an HE machine, sitting below the bottom of the door glass, is usually exactly right. And load sensing runs for up to a minute before any water arrives at all, so a machine that appears to sit and do nothing at the start of a cycle is very often just weighing the laundry.
Work the fill path
1. Both taps, fully open
Check hot and cold, and turn each one fully open rather than most of the way. If anyone has done plumbing work recently, confirm nobody left an isolating valve part-closed on their way out.
2. Test household flow
Close the valves, disconnect the hoses at the wall into a bucket, and briefly open each valve. Strong flow from both means the supply is fine and the problem is downstream, inside the machine’s reach. Weak or no flow means the problem is your plumbing and no amount of appliance work will fix it.
3. Inspect the hoses
Look along the full length for kinks, crushing, or a hose trapped behind the machine. Leave clearance behind the unit so vibration cannot pinch its own hoses — this is the fix for the creeping failure described above, and it is permanent.
If it’s cold weather, suspect a frozen line before anything mechanical. Warm the room and allow time to thaw rather than applying direct heat to a pipe.
4. Reset a flood-safe hose
If your hoses have flood-safe or auto-shutoff heads, close the tap, disconnect, let the pressure equalise for a minute, then reconnect and open the tap slowly. Opening a tap fast is precisely what trips them, so doing it quickly again just re-arms the problem you are trying to clear.
5. Clean the inlet screens
With power off and both valves closed, disconnect the hoses at the machine end. The mesh screens sit in the inlet ports. Rinse them clean; don’t force them out or reshape them, because a deformed screen will not seat properly afterwards. Reconnect hand-tight plus a light turn, then check for drips when the water goes back on.
6. Confirm hot and cold aren’t crossed
If cold cycles run hot, the hoses are reversed. On many machines that also produces a fill-related code rather than an obvious temperature complaint — Samsung reports it as 4C2/4E2 rather than 4C. Swap the connections at the wall and retest.
Stop-use warning: Turn off both valves and unplug the machine before disconnecting any hose. Have towels ready — hoses hold water even after the taps are closed. If you find water near electrical components, stop and unplug at the breaker.
Where the flow stopped, and what that means
| What you observed | What it means | Where to go next |
|---|---|---|
| No flow from the wall with hoses off | Household supply problem | Plumbing, not the machine |
| Strong flow at the wall, none into the machine | Downstream of the tap | Screens, then inlet valve |
| One temperature works, the other doesn’t | Single-side fault | That side’s valve, hose, screen |
| Screens came out clogged | Confirmed and common | Clean, retest, expect improvement |
| Flood-safe hose fitted, no flow | Likely tripped check valve | Reset it slowly |
| Everything clear, still nothing | Inlet valve or sensor | Service |

Samsung: 4C2 is a different fault wearing a similar code
- Expect
4C,4E,1 4C,nForE1— Samsung’s “not filling” family, meaning “water is not entering the washer correctly” (Samsung washing machine information and error codes). - Watch for
4C2/4E2/nF1/CEinstead. This is a different fault wearing a very similar code: “the water from the cold water supply is extremely hot.” It means your cold inlet is being fed hot water, which is almost always crossed hoses at installation. Nothing else on this page applies — swap the connections and you are done. - Samsung’s fill-issue guidance covers valve position and hose routing, and stresses connecting each supply line to its matching valve (Samsung, “water fill issues with Samsung washing machines”, read live on 2 September 2026); the installation documentation covers the connection itself (Samsung, “install a Samsung washing machine in your home”, read live on 2 September 2026). Neither covers inlet screens — that procedure is documented by LG, below.
- Full code breakdown: Samsung washer 4C or 4E error.
LG: flood-safe hoses are named as an IE cause
- Expect
IE— LG’s inlet error. LG lists the causes plainly, starting with “there is a water supply outage or the faucet is turned off” (LG washer — troubleshooting fills too slow / does not fill). - LG documents the self-pinching problem explicitly: vibration during wash or spin can move the machine enough to bend or crush its own hoses, restricting flow on the following cycle. This is why the fault so often appears with no apparent cause.
- Flood-safe hoses are called out by name: “Flood safe hoses may interrupt water supply and cause an IE error code” (inlet hose installation — washing machine).
- Water pressure should sit within 14.5–116 PSI on front-load models.
- LG also documents frozen lines as a distinct seasonal cause (LG, “why is there no water in my front load washing machine”, read live on 2 September 2026).
Whirlpool, Maytag, Amana and Kenmore 110 share one low-flow code
Expect F8E1 or Lo FL — the shared-platform low-flow code. The checks on this page apply unchanged; screens and flood-safe hoses are the usual findings.
Frigidaire and Kenmore 417: E11 or E41 on the Electrolux platform
Expect E11 or E41 on the Electrolux platform.

Prove both temperatures fill, then check for drips
- With the drum empty, start a short cycle and confirm water enters promptly once sensing finishes.
- Confirm both temperatures fill — run a warm cycle to exercise each valve, because a cold-only test leaves half the system untested.
- Confirm no fill code appears.
- Check behind the machine for drips at every connection you touched.
- Run one normal load to confirm it holds.
Frozen pipes and dead valves are not DIY
- Strong flow at the wall, screens clean, hoses clear — and still nothing enters.
- One temperature never works after cleaning that side’s screen and confirming its valve.
- A fill code persists through every check above.
- You suspect frozen pipes inside a wall.
- Water has reached any electrical component.
FAQ
Water comes in, just very slowly. Same path, lower threshold — usually partially clogged screens or a partly closed valve. See washing machine fills too slowly.
It fills, then drains straight away without washing. That’s siphoning, from a drain hose pushed too far into the standpipe. See washing machine fills then drains.
The drum looks like it has barely any water even on a full load. Usually normal. HE machines use a fraction of the water older machines did, and the correct level often sits below the bottom of the door glass.
It sits there doing nothing for a minute before any water arrives. That’s load sensing, not a fault. See washing machine stuck on sensing if it never progresses past it.
I replaced the hoses recently and now it won’t fill. Check for a flood-safe head that tripped when you opened the tap, and confirm the screens weren’t dislodged during the swap. Both are common right after a hose change.
No water and the drum still has water from last time. Deal with the drainage first — many machines won’t add water until the tub is confirmed empty. See washing machine won’t drain.
The main fill works but the built-in faucet or sink jet doesn’t. That is a separate water path with its own valve, so the main fill working tells you very little about it. On Samsung models with Active WaterJet, see Samsung Active WaterJet not working.
