Beko Dryer Error Code E12
The drum is not turning because the drive belt has snapped or come off. On these models the belt is a known wear item, especially if it has been slipping or squeaking.
Applies to: Beko heat-pump tumble dryers, BX B7S and BLED platform models
Common causes
- Snapped drive belt
- Belt slipped off the motor pulley
- Seized idler pulley or drum bearing that wore the belt through
What to check, in order
- Open the door and turn the drum by hand — a drum that spins very freely with almost no resistance suggests the belt has gone.
- Listen at start-up: a humming motor with no drum movement points the same way.
- Belt replacement means opening the cabinet — a technician job for most owners.
Clear the code and test
- Fix what the checks above found first — a filter cleaned, the vent or hose freed. Clearing the code without fixing the cause only brings it back.
- Close the door and plug the dryer back in (or restore its breaker).
- Run a short timed drying cycle with a small load and watch the point where the code appeared before.
- If the cycle finishes with no code, the fault is cleared. If the code returns, write down the code and the stage before calling a technician — it speeds up the diagnosis.
When to call a professional
This code usually points to a faulty part, wiring or the control board on a Beko dryer. Run the checks above to rule out the simple causes, then book a technician — and book one straight away if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code E12, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
Repair or replace?
This fault is in professional territory: the fix usually means a major part or board-level work, and the labour adds up. If your machine is already well into its service life, get the repair quote first, then compare it with the price of a current equivalent model before you decide. Paying a large share of a new machine's price to repair an old one is rarely the better deal; replacing a machine over one cheap fault is wasteful too.

Parts are model-specific. Find your model number first — usually on a label inside the door or on the back — and match the part to that number before ordering.
