[5 Fixes To resolve] How To Fix The Roomba Error 15?

Error 15 on your Roomba indicates that your Roomba has encountered problems that prevent it from communicating properly with the home base or the app. To resolve the issue, try pressing the Clean button on the robot whenever it encounters this problem.

Later in this article, I’ll go over additional ways to resolve this issue, such as performing a robot reset, reconnecting the Roomba to your Wi-Fi, and more.

What Does This Error Mean?

  • Knowing what Error 15 is, becomes much easier thanks to iRobot classifying all errors into error codes that help troubleshooters identify an issue.
  • According to iRobot, an Error 15 message usually indicates a communication problem with the Roomba.
  • This could be due to a problem with the internal components, the Roomba’s settings, or a problem with your Wi-Fi network.

Why Does This Error Occur?

  • Because Error 15 indicates a communication error, determining why it occurred becomes easier.
  • The error could be caused by internal Roomba components failing to communicate with the home base or your phone.
  • It may also occur if there are numerous obstacles, metallic objects, or thick walls between the Roomba and its home base.
  • If you usually control the Roomba with your smartphone, you may encounter this problem if your Wi-Fi router is having trouble staying connected to the robot.

How To Fix This Roomba Error?

1. Restart Cleaner

  • When this error occurs, some Roomba models prompt you to restart the cleaning process.
  • Restarting the cleaner allows the Roomba to reconnect to its home base and re-establish the lost connection.
  • To restart the cleaning process, press the CLEAN button on the Roomba.
  • The robot will take a few seconds to reorient itself and resume its cleaning routine.
  • If everything goes well and the robot completes its cleaning cycle, you’ll know what to do the next time you encounter this error.

2. Check Wifi

  • One of the reasons you couldn’t resolve the problem by restarting the cleaner was that the Wi-Fi network you were using encountered problems while the Roomba was performing its routine.
  • Log in to the router’s admin tool by entering into your browser’s address bar.
  • Find the default username and password for the tool, which can be found under your router or in the router’s manual.
  • Check and disable the QoS service if it is enabled.
  • Check to see if your firewall is also preventing your Roomba from connecting to your Wi-Fi.

3. Reconnect Roomba To Wifi

Because Wi-Fi issues can cause Error 15, some users reported that reconnecting to their Wi-Fi fixed the problem.

  • To accomplish this, you must first disconnect the Roomba from your Wi-Fi network and then reconnect it.
  • To disconnect the Roomba (S, I, and 900 series) from your Wi-Fi network, follow these steps:
  • Hold down the Home, Clean, and Spot Clean buttons at the same time.
  • Wait for the light surrounding the Clean button to begin spinning before releasing the buttons.
  • The Roomba will restart and complete the reset on its own.

4. Reboot Roomba

If the problem persists, try rebooting the Roomba.

You only need to enter a simple button combination to get started.

To reactivate an S Series Roomba:

  • Hold the Clean button down for at least 20 seconds.
  • The ring of white light around the bin’s lid will rotate clockwise.
  • Wait a few minutes for the Roomba to restart.
  • When the white light goes out, the process is complete.

5. Reset Roomba

If everything else fails, you can hard reset the Roomba to factory settings.

This means that the robot’s custom settings, such as scheduling, home layout maps, and Wi-Fi settings, will be erased.

To hard reset the Roomba, follow these steps:

  • Ascertain that the Roomba has been configured using the iRobot Home app.
  • In the iRobot Home app, go to Settings.
  • Select Factory Reset and confirm the prompt if prompted.
  • The Roomba will now start the factory reset process.
  • Allow enough time for the process to complete.

If you encounter any problems while troubleshooting or require additional assistance to resolve Error 15, please contact iRobot.

Check that all of your Roomba’s buttons work after you’ve tried a reset. Take careful notes on the clean button and ensure that it is operational. If not, try cleaning the Roomba’s dust and electrical contacts, as well as its filters. Charge the Roomba as well to see if it can correctly recognize its home base. If your Roomba isn’t charging, try reinstalling or replacing the battery.
