Samsung Oven Error Code bAd LinE
The oven detected that its own power connection is wrong. It is an installation fault, not a cooking fault, and the correction is at the terminal block by someone qualified to make it.
Also shown as: Bad Line
Common causes
- The power cord was wired incorrectly at the terminal block during installation
- Loose terminal connections on the power cord
- The supply was connected in a way the oven does not accept
What to check, in order
- Stop using the oven and switch off its breaker.
- Note when the message appeared: it almost always shows up right after installation or after the cord was replaced.
- Have the installer or a qualified electrician check the cord connections at the terminal block against the installation instructions; do not rewire it yourself.
- Once the connection is corrected, restore power: Samsung states the message disappears when the cord is connected properly.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down 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 Samsung oven. 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 at the tap.
- 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 bAd LinE, 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 that may be involved
Power cordTerminal block
Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
