What Is Error 43 on Roomba?

I was in the middle of a much-needed cleaning session when my loyal Roomba suddenly stopped working. The dreaded Error 43 code flashed on its display, sending shivers down my spine. Determined to solve this robotic enigma, I embarked on a quest for answers.

As it turns out, Error 43 is a common Roomba issue that can have several underlying causes. In this comprehensive guide, we’ll delve into the depths of Error 43, exploring its definition, potential causes, and the steps you can take to resolve it.

Types of Error 43 Codes

Error 43 does not come in one, but two forms, each with its own distinct culprit:

  • Error 43 Main Brush: This error indicates a problem with the Roomba’s main cleaning brush, responsible for sweeping up dirt and debris.
  • Error 43 Side Brush: Conversely, this error points to an issue with the Roomba’s side brush, designed to reach into corners and along edges.

Troubleshooting Error 43

To resolve Error 43, it’s essential to determine which type of brush is causing the issue. Here are some troubleshooting steps for both:

Error 43 Main Brush

  • Check for hair or debris: Remove the main brush and thoroughly clean it, removing any tangled hair or debris that may have blocked its rotation.
  • Inspect the brush bearings: Examine the bearings on both ends of the brush. If they are worn or damaged, they may need to be replaced.
  • Reset the Roomba: Turn off the Roomba, wait a few minutes, and then restart it. This simple step can sometimes resolve minor software glitches.

Error 43 Side Brush

  • Unjam the side brush: Gently move the side brush back and forth to remove any stuck objects or debris. Ensure it can rotate freely.
  • Replace the side brush: If the brush is damaged or worn, it may need to be replaced. Consult your Roomba’s user manual for instructions.
  • Clean the side brush motor: Remove the side brush module and clean the motor with a soft brush. Debris accumulation can interfere with its operation.

Expert Tips

To prevent future Error 43 occurrences, consider these expert tips:

  • Regular maintenance: Regularly clean and maintain your Roomba, including removing debris from the brushes, emptying the dustbin, and cleaning the sensors.
  • Avoid obstacles: Keep your cleaning area free of obstacles that could tangle the brushes or prevent the Roomba from moving freely.
  • Update software: Ensure your Roomba’s software is up to date, as firmware updates can sometimes resolve Error 43 issues.
