Quick answers — read this first
Why did my reed diffuser stop working? A reed diffuser has no moving parts, so it "stops" for one of two simple reasons: the reeds are clogged (old reeds fill with dust and thickened oil and stop wicking) or the oil has run low. Fit fresh reeds, flip them, and top up with a SOSA refill if needed. From ₹2,399.Is it broken? No - there is nothing mechanical to break. It just needs fresh reeds or more oil.

Straight answer
Nothing is broken - it needs reeds or oil
A reed diffuser is beautifully simple: no motor, no electronics, nothing to break. So when it "stops working," it is almost always one of two things. Clogged reeds: over a few months, fibre reeds fill with dust and thickened oil and can no longer wick - clogged, old reeds - not empty oil - are the usual reason a diffuser goes quiet. Empty or low oil: the oil has simply wicked away. The fix takes two minutes: fit fresh reeds, flip them so both ends are coated, and top up the oil to the neck with a SOSA refill. That is it - it will be as good as new. From ₹2,399.
One line: a reed diffuser has nothing to break - it stops because of clogged reeds or low oil; fresh reeds and a refill restart it. From ₹2,399.

The two causes, and the two-minute fix
1
Reeds
Clogged, not broken
Old reeds stop wicking. Swap in fresh reeds and flip them - the fix for most 'dead' diffusers.
2
Oil
Simply run low
If the vessel is low, top it up to the neck with a refill. Do not let the reeds sit dry.
3
Placement
Give it airflow
Once refreshed, keep it somewhere with gentle airflow (not a draught) so the scent carries into the room.
