Common causes

Sabbath mode switched on deliberately for the Sabbath or a holiday
Sabbath mode switched on accidentally by the Freezer and Wi-Fi button combination

What to check, in order

Safety first. Switch the appliance off and unplug it before checking anything inside it. If you are not comfortable with any step, stop and call a technician.

Touch the display to wake it, then press and hold the Freezer and Wi-Fi buttons together for about 3 seconds until Sb disappears
On some models the button pair is Freezer and Water Filter Replace instead; check the manual if the display does not respond
If you do nothing, Sabbath mode switches itself off automatically after 96 hours

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 display is not a fault, so there is normally nothing to book. Call a technician only if the machine also behaves abnormally, or 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 Sb, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
