Direct answer
For the Haier HWD100 combination washer/dryer, verify both water supplies, inlet screens, hose routing and the selected cycle before treating the inlet valves or pressure system as failed. First, open both faucets fully and note whether hot, cold or both are missing.
What this covers
- Haier HWD100 combination washer/dryer (HWD100-B14979*)
- Combination platform; controls and codes are region-specific.
- The specific fault this record addresses: will not fill with water or fills too slowly
What it does not cover
- ×The same symptom on a different Haier product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
One or both supply faucets are closed or only partly open
What separates it No fill at all, or the machine fills only with cold or only with hot. Each temperature comes from its own hose and its own valve, so a single closed faucet produces a partial rather than total failure.
How to confirm Open both faucets fully and note which temperature is missing — that identifies which side of the supply to inspect.
- 2
The inlet screens are clogged with sediment
What separates it Filling is very slow rather than absent, often worse on one temperature than the other, and the machine may time out and report a fill fault.
How to confirm With both faucets closed and power disconnected, the small screens in the inlet valve ports are owner-cleanable on most machines. Sediment collects here after plumbing work or in hard-water areas.
- 3
A supply hose is kinked behind the machine
What separates it Slow or absent fill that began after the machine was moved, or after something was stored behind it.
How to confirm Pull the machine out far enough to see the full hose run rather than reaching blindly behind it.
- 4
The door or lid is not locked, so filling never starts
What separates it The cycle appears to start but no water enters and no fault appears immediately. A front-load washer cannot fill until the door locks, because the water level sits above the door opening.
How to confirm Watch for the lock indicator before the fill phase. If it never appears, this is a door-lock problem rather than a water-supply one — see door-lid-not-locking.
- 5
The machine is filling correctly and the level only looks wrong
What separates it Water enters but never submerges the load, on a high-efficiency machine. This is by far the most common reason people report a fill problem on a modern washer.
How to confirm Watch whether every item becomes thoroughly wet and turns over during the wash action. If it does, the machine is working as designed — see not-level-water-too-low.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether no water enters at all, or water enters slowly, or water enters normally but to a level that looks too low.
- Which temperature is missing — hot, cold, or both — since each has its own hose, faucet and valve.
- Whether the door or lid lock indicator appears before the fill phase should begin.
Open both faucets fully and note whether hot, cold or both are missing
ReversibleThis identifies which supply side to inspect and rules out the most common cause in seconds.
Disconnect power and close both faucets before inspecting hoses and inlet screens
ReversibleNever work on an inlet valve with water pressure or power present.
Clear kinks and clean the owner-accessible inlet screens
ReversibleSediment in these screens is a common cause of slow filling, particularly after plumbing work or in hard-water areas.
Confirm the door or lid actually locks before the fill phase
ReversibleA front-load washer that cannot lock will never fill, and that is a lock fault rather than a supply fault.
Run a normal fill and confirm the water stops at the expected level
ReversibleOn a high-efficiency machine, the expected level is well below the top of the load.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- HWD100-B14979*. Combination platform; controls and codes are region-specific.
- Type — COMPACT washer (small-space)
- A COMPACT Haier washer for small spaces, with a door gasket if front-loading. Small drum means small loads — overloading causes poor cleaning, unbalance and long cycles. Built for apartments and tight installations.
- Compact behaviour
- Compact washers spin fast and can vibrate/'walk' if not level or if the shipping bolts were left in — confirm those at install. If this model is a combo with ventless drying, a 'not drying' issue is the condenser/lint path, not a vent.
- Care
- Front-load gasket care (wipe dry, door ajar) governs odour; keep loads modest for a small drum.
- Size class
- One of the smaller models in its line, which has a direct consequence: a smaller body holds a smaller battery, so its rated runtime is genuinely lower than its larger siblings. Runtime that looks poor beside a Max is usually this rather than a fault.
- Symptom boundary
- This record covers Haier HWD100 combination washer/dryer when it will not fill with water or fills too slowly. A different symptom on the same hardware, or this symptom on a different Haier product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Close both faucets immediately for an uncontrolled fill, an overflow, or a leaking hose — do not wait to finish diagnosing.
- !Never probe or disassemble a live inlet valve with power connected.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Haier Appliances publishes this as "Support". Official Haier manuals, model support and service entry point. What that article does not carry is the model boundary — it is written for a product line, and HWD100-B14979* is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
My compact Haier washer vibrates and moves during spin.+
Compact washers spin at high speed and vibrate more than full-size ones. Confirm the shipping bolts were removed at installation (a very common cause of violent shaking if left in), level the machine with locked feet on a solid floor, and keep loads small and balanced, since a small drum unbalances easily with a heavy single item. Those installation checks fix most compact-washer vibration.
The washer only fills with cold water, never hot.+
Each temperature comes from its own hose, faucet and inlet valve, so a missing hot fill points at the hot side specifically — check that the hot faucet is fully open and that the hot inlet screen is not clogged with sediment.
Barely any water goes in — is it broken?+
On a high-efficiency washer this is usually normal. These machines are designed not to submerge the load. What matters is whether every item becomes thoroughly wet and turns over during the wash action; if it does, the fill level is correct even though it looks wrong.
Does this answer apply to every Haier model?+
No. It is scoped to HWD100-B14979*. Combination platform; controls and codes are region-specific.
What should I record before troubleshooting not filling or slow fill or no water?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing not filling, slow fill, no water. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Close the faucets for an uncontrolled fill or leak; never probe a live inlet valve.
