Wyze Robot Vacuum Error Codes - Complete Troubleshooting Guide
Your Wyze Robot Vacuum just stopped mid-clean with a red flashing light and cryptic beep pattern. What does it mean? How do you fix it?
Wyze error codes signal specific problems - and 92% can be fixed in under 10 minutes without replacement parts. This guide decodes every Wyze error code (E01-E12) with exact fixes and prevention strategies.
Covers all models: Wyze Robot Vacuum, Wyze Robot Vacuum S.
How Wyze Error Codes Work
Wyze's System: Unlike Roomba's numbered errors or Roborock's app messages, Wyze uses both LED patterns and in-app error codes.
Three Ways Wyze Shows Errors:
- Red LED Flash Pattern: Number of flashes = error code number
- Beep Pattern: Audio confirmation (if volume enabled)
- Wyze App Notification: Detailed error message with code
Reading LED Patterns:
- 2 flashes, pause, repeat = Error E02
- 5 flashes, pause, repeat = Error E05
- Solid red (no flashing) = Critical error, check app
💡 Wyze Quirk: Error codes reset after fixing the issue - no manual error clearing needed like some brands.

- Reinstall: Screw back on (snug but don't overtighten)
- Test Run: Start cleaning to verify error cleared
Time: 3-4 minutes
Success Rate: 92%
Cost: Free (or $8 for replacement brush if damaged)
⚠️ Wyze Specific: Wyze side brushes have thinner arms than Roomba's. Don't overtighten the screw - it can crack the brush hub.
Prevention: Check side brush weekly for hair buildup.
Error E03: Main Brush Roller Stuck
What It Means: Main brush roller is jammed and can't spin freely.
Why It Happens: Hair wrapped around brush ends, debris stuck in brush chamber, or foreign object blocking rotation.
Symptoms:

Common Questions
What do solid red lights on Wyze robot vacuum mean?
Solid red (not flashing) typically means critical error requiring immediate attention. Check the Wyze app for specific error code and message. Most common: dustbin missing, LiDAR blocked, or charging error.
How do I reset Wyze robot vacuum to clear error codes?
