πŸ” Troubleshooting Suggestions

Error code A indicates that the tray motor is either losing its power or not working at all. There are three common reasons underlying a defective motor:

  1. Its internal gearbox may have a physical damage, such as a broken or jammed gear tooth.
  2. Its carbon brush may have degraded naturally after extended use.
  3. Its cable or pin may have a loose connection.

In tandem with this code, the status light will also turn into the solid red color, and a special diagnostic mode will activate automatically. The onboard buttons will then function as follows:

  • Key 1 (Clean): Rotates the tray forward (stops at the neutral position if passing by)
  • Key 2 (Bin): Rotates the tray backward (stops at the neutral position if passing by)
  • Key 3 (Sifter): Opens the sifter
  • Key 4 (Fn): Closes the sifter

A new tray motor will be needed if the tray doesn't move after pressing Key 1 or 2. Otherwise, please double check the connector pin by referring to the video guide below.
