Internal error: 105 left wheel short circuit - Model roborock.vacuum.a19 (S4 Max)

I need help. Error keeps occurring, even after I push/pull it for 10 seconds. The robot was purchased in June 2021.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.

  • You are not alone. I have the same issue with my S4Max. Mine is right at 1 year old as well.

    @EAS:

    Hello,


    Thank you for taking the time to reach out to Customer Support and we are sorry to hear about the trouble you are having with your device.

    If the following method doesn't help, you can try a factory reset on the robot.

    1. Put the device on the ground, push it aggressively forward&backward for around 10 sec (like using an eraser). You can push it with some force like in the video below:

    2. When you feel there's less resistance in the wheels, start cleaning again to see if it works.


    Notice:

    Manually pushing the device would cause an overheat of the motor. If the resistance is still high after erasing the wheel for 10 seconds, please wait for a while until the motor cools down, and then try it again.


    If neither the pushing nor reset won't address the issue, the device may need to be repaired. Please reach out to our support team at support@roborock.com to get further assistance.
