Xiaomi Roborock S5 Docking Station CDZ02RR Error 13 couldn`t charge properly - Capacitor 420v 68uf 16x25 Replacement

Introduction

The robot vacuum tries to dock several times, starts charging, and leaves the dock shortly after.

This behavior repeats several times, until the robot stops with "Error 13 couldn't charge properly" in front of the charging station. (also watch the Video - 3x speed)

Most of the time this is not an issue with the robot but rather of the charging station.

Normally it is done by cleaning the charging contacts on the Robot and the docking station.

If that doesn't fix the problem permanently, it is most likely due to a faulty capacitor.

420V ELKOs mit 68uf sind praktisch nicht erhältlich. Kann man auch auf einen 400 oder 450 V zurückgreifen? Wenn ja auch welchen? Danke

Hi @danielk223,
ja siehe oben.
Genau deshalb habe ich als Ersatzteil auch schon einen üblicheren angegeben, der funktioniert.
Viel Spaß!

Ah even erst gesehen, vielen Dank. Dann hoffen wir mal, dass das die Lösung ist :)

ELKO ist getauscht, Problem besteht leider weiterhin. Also ist es wohl das Mainboard des Roboters…

Daniel K. -

Verhält sich der Roboter so wie im Video oder anders?
