How Samsung Jet Bot Error System Works

Samsung uses letter-number system:

• C-codes (C01-C10): Component errors (physical problems)
• E-codes (E10-E99): Electrical/power errors
• S-codes (S01-S09): Sensor errors

Error Display:

• Beeping pattern (1-5 beeps)
• LED light flashing red/orange
• SmartThings app shows code and description
• Display on Clean Station (if equipped)

Unlike Roomba (numeric only) or Roborock (voice alerts), Samsung uses visual + app notifications.

Common Questions

How do I clear error codes on Samsung Jet Bot?

Fix the underlying problem first, then power cycle robot (off 30 seconds, back on). Error clears automatically once issue resolved. Don't just factory reset - this doesn't fix hardware problems like stuck brushes or dirty sensors.

Why does my Jet Bot keep showing C03 error every few days?

C03 (main brush stuck) repeats if you have pets with heavy shedding. Clean main brush weekly instead of monthly. Also check if brush bristles worn flat (under 5mm height) - worn brushes tangle faster. Replace brush roller every 6-8 months with daily pet hair cleaning.

Can Samsung Jet Bot errors damage the robot if ignored?

Yes. Running robot with stuck brush (C03) or stuck wheel (C02) forces motors to work under strain, shortening motor lifespan. Always fix errors immediately. Samsung error system designed to protect robot from damage by stopping cleaning when problem detected.

What does E20 battery error mean for Jet Bot lifespan?

E20 after 18+ months with daily use is normal - battery reaching end of life. Replacement battery ($40-100) gives robot 2+ more years. If E20 appears in first 12 months, warranty should cover replacement (contact Samsung). Battery is designed consumable part, not defect.

Why does my Jet Bot AI+ show S01 camera error but lens looks clean?

Even invisible smudges or fingerprints trigger S01. Use clean microfiber cloth (not paper towel, not shirt). If error persists after thorough cleaning, camera lens may be scratched or damaged - requires Samsung service ($60-100 repair).

Do I need SmartThings app to see Jet Bot error codes?

No, but highly recommended. Without app, you only get beep patterns and LED flashing (harder to decode). SmartThings app shows exact code (C03, E19, etc.) plus plain-English description and fix suggestions. Free app available on Android/iOS.
