How to check the error log
Samsung ovens do not have a user-accessible error log. The code stays on the display until you fix the cause or cut power at the breaker for 3 minutes; if it returns after a reset, treat it as real.
Clear the log after a repair so you can tell whether the fault has really gone.
FAQ
What does SE mean on the Samsung range and wall oven?
Defective or stuck key on the control panel (short in the touchpad membrane). The board sees a key held down or shorted. Moisture or grease under the membrane, a stuck button, or a failed membrane. On older ranges it can also be the ribbon cable to the control board.

SE during startup or during use?
Samsung range and wall ovens report SE any. That timing is a useful clue when narrowing the cause.

Generally yes — SE is more of an annoyance than an emergency. Fix it when convenient; just do not let the cause sit for months.
Will SE clear on its own?
Sometimes. Try the reset and cleaning steps first — they cost nothing and clear the milder cases. A code that returns within a day or two needs the parts fix.
