What’s in the Box
WSNUEEE AE103 retail box with the diffuser, a 100 mL oil bottle and the printed user manual laid out beside it
  • ✓AE103 Aroma DiffuserThe body, the atomized head and the built-in plug — everything above the bottle.
  • ✓100 mL Oil BottleRefillable. Fill it with pure essential or fragrance oil — no water.
  • ✓User ManualThis guide, plus a quick card showing the app pairing password.
Keep the Filter
There is a small filter inside the tube that connects the bottle to the atomized head. Leave it in place — it keeps oil residue out of the air path.

Where Scent Becomes a Service
Because the AE103 is app-scheduled and covered up to 500 sq ft, the same unit is used in guest rooms, washrooms, meeting rooms and brand stores — anywhere the scent has to run to a timetable without anyone touching it.
Installation

Setup in 60 Seconds

Four steps from the box to your first scent. No water, no warm-up.

1
Unscrewing the lower cover from the AE103 diffuser body
Unscrew the Lower Cover

Turn the lower cover counterclockwise and lift it away from the body.

2
Unscrewing the oil bottle to fill it with essential oil
Fill the Oil Bottle

Unscrew the bottle and fill it with pure essential or fragrance oil. No water.

3
Screwing the filled oil bottle back into the base of the diffuser
Reassemble

Screw the bottle back into the base, then screw the lower cover on until it seats.

4
Plugging the AE103 diffuser into a wall socket, keeping it upright
Plug In Upright

Plug it into the socket and keep the unit vertical. Rotate the plug prongs if the outlet is sideways.

⚡ Three Things Worth Knowing
1. Do not remove the filter inside the tube. 2. Keep the unit upright whenever oil is in the bottle — tilting or laying it flat lets oil overflow. 3. The first time you pair it, the app asks for the password 8888.

Operating Basics

Indicator & Reset Button

Two small controls carry the whole on-device story. Everything else lives in the app.

Reset

Short pressRestores the original app password, 8888.

Long pressRestores the diffuser to its factory settings.

Indicator

When the light is on, the diffuser is inside a working period and actively diffusing. When Bluetooth pairs successfully, the unit answers with a short “beep”.

Why There Is No On/Off Switch
The AE103 is an APP version unit: on and off are simply your schedule. The indicator tells you whether the current moment falls inside one. If you never pair the app, the unit falls back to its stored schedule and the grade button still works.
App Control

Pair It with the Scent Marketing App

The app controls everything the AE103 does — when it runs, for how long, and how strong. Pairing takes about a minute.

Scan the code for your phone, or search “Scent Marketing” in Google Play or the App Store.

  • Turn on Bluetooth before you open the app.
  • Allow location access — Android needs it to scan for nearby devices.
  • Keep the phone within a few feet of the diffuser while pairing.

What Each Screen Does
Device control → Set is the one you will use most: rename the unit, note where it lives, and add working periods. Slide a period row sideways to delete it.

Device control → About carries the PCB, equipment and app versions — handy if you ever need support — and the way in to Change password.
⚠ Forgot the Password?
Press the reset button on the unit to restore the factory setting. The factory password is 8888. A short press on the same button restores the password only; a long press returns the whole diffuser to factory defaults.

Reading the Numbers
The work time is 15 seconds in every preset grade. What changes is the pause: a longer stop time means a gentler scent and a slower draw on the bottle.
Custom Stall
Tick Custom Stall in the app to set your own work time (3–15 s) and stop time (60–900 s) instead of using a preset.
Care

Cleaning & Maintenance

Two reasons to clean: you are changing oils, or the mist has weakened.

Clean When
  • You are about to switch to a different essential oil.
  • The atomization volume becomes weak, or the scent seems muted.
  • You have been running the same oil for a long stretch and residue is starting to build.
Cleaning Steps
  • Unplug the diffuser, then pull the atomized head out and loosen the bottle.
  • Fill a container large enough to hold the bottle with rubbing alcohol and soak the bottle for 5–10 minutes.
  • Rinse the bottle with clean alcohol and pour it away.
  • Leave everything to air-dry completely before reassembling. Never run the unit while parts are still wet.
⚠ Keep Water Away
The AE103 is a waterless diffuser. Never put water in the bottle, never rinse the body under a tap, and never submerge any part other than the bottle. Water in the air path is the fastest way to ruin an atomized core.
Safety

Important Warnings

Four rules cover almost everything that can go wrong with an oil diffuser.

Keep It Vertical

Keep the machine upright. Tilting it or laying it flat can make oil overflow, and the efficiency of the machine may be affected.

Do Not Modify

Do not modify, disassemble or repair the machine yourself. There are no user-serviceable parts inside the body.

Mind the Environment

Do not use this product under high humidity or high pressure conditions. Keep it away from open flames and direct sunlight.

Screw, Don’t Tape

If you mount the machine on a wall, use screws rather than tape. A tape-mounted unit can work loose and fall — and a fall spills the oil.

Unplug before cleaning. Always disconnect the diffuser from the socket, and let it stand upright while you work on it.
Three orientation diagrams for the AE103: upright is correct, tilted is not allowed, laid flat is not allowed
From left: upright — correct · tilted — not allowed · laid flat — not allowed. Oil reaches the atomized head by gravity and a wick, so orientation is not cosmetic.

Troubleshooting

Before you ask for a repair, run through these first — they cover the great majority of cases.

Swipe the table sideways to see the full remedies →
SymptomRemedy
Does not diffuse Check whether the machine is in a “not working period”. If it is, it will not spray — that is the schedule, not a fault. Otherwise, check whether the air pump is damaged; if it is, replace it with a new one.
Spray little Check whether the gasket is damaged or loose, and adjust or replace it. Then check whether the atomized core is plugged — clean it with alcohol, or replace it with a new one.
Oil spill Check whether the atomized head is damaged. A damaged head leaks oil instead of atomizing it.
Oil overflow Check whether the oil bottle is loose and install it correctly. Check the gasket on the atomized head for damage and replace it if needed. Finally, keep the machine vertical — tilting it or laying it flat will cause oil to overflow.
Still Stuck?
Try a long press on the reset button to return the diffuser to factory settings, then pair it again with password 8888. If that does not clear it, contact us at wsnueee@outlook.com before arranging any repair.

Questions

Frequently Asked Questions

Quick answers to what AE103 owners ask most.

What is the WSNUEEE AE103?
The AE103 is a waterless aroma diffuser that plugs into a wall socket and is controlled over Bluetooth from the Scent Marketing app. It runs on 2 W, holds a 100 mL refillable oil bottle, covers up to 500 sq ft (75 m³ / 2,650 ft³), and offers four preset concentration grades plus a custom setting. There is no water tank and no power cord.
How do I set up the AE103?
Unscrew the lower cover. Unscrew the oil bottle and fill it with pure essential or fragrance oil — no water. Screw the bottle back into the base, screw the lower cover on until it seats, then plug the unit into the socket, keeping it upright. Rotate the plug prongs if your outlet is sideways.
Do I need to add water?
No. The AE103 atomizes pure oil. Adding water or a water-based oil will clog the atomized core and may damage the diffuser.
How do I pair the AE103 with my phone?
Install the free Scent Marketing app, turn on Bluetooth and allow location access. Choose Bluetooth version, tap the refresh icon to scan, select your diffuser in the list, then enter the password. The factory default password is 8888.
What is the factory password, and how do I reset it?
The factory password is 8888. To change it, open Device control → About → Change password and enter the new password twice. If you forget it, press the reset button on the unit — a short press restores 8888, and a long press restores the whole diffuser to factory settings.
What do the concentration grades G1 to G4 mean?
Each grade sets how long the unit pauses between sprays. Work time is 15 seconds in every preset grade; the stop time runs from 285 seconds on G1 down to 60 seconds on G4. A longer stop time means a gentler scent and a slower draw on the oil. You can also tick Custom Stall to set your own work time (3–15 s) and stop time (60–900 s).
How long does the 100 mL bottle last?
The bottle holds roughly 90 g of oil. At G1 the diffuser draws about 0.07 g per hour of operation, so a full bottle lasts well over a month of continuous running; G4 draws more than four times as much (0.30 g/h) and empties the bottle proportionally faster. How long it lasts in practice depends on how many hours a day you run it.
Why does the unit not spray?
First check the schedule. If the current moment falls outside every working period you have set, the AE103 stays silent by design — that is the “not working period”. If the schedule is fine, check whether the air pump is damaged and replace it if so.
What does the indicator light mean?
When the light is on, the diffuser is inside a working period and diffusing. When Bluetooth connects and operates successfully, the machine emits a short “beep”.
How often should I clean the AE103?
Clean it whenever you switch to a different essential oil, and any time the atomization volume becomes weak. Unplug first, pull out the atomized head, loosen the bottle, then soak the bottle in rubbing alcohol for 5–10 minutes and let everything air-dry completely before reassembling.
Can the AE103 be wall mounted?
Yes, but use screws rather than tape. A tape-mounted unit can work loose and fall, and a fall spills the oil. Keep the machine vertical at all times.
Which oils can I use?
Pure essential oils and pure fragrance oils. Do not use diluted or water-based oils, thick or highly viscous oils, perfumes with a high alcohol content, or oils with added carrier liquids.
