Maintenance failure warning

What happened? 

The Original Prusa MK3.5/S can be equipped with an MMU3 upgrade kit. Having the MMU3 upgrade kit installed significantly increases the number of loads and unloads. 

After a set number of consecutive failed loads and unloads, the printer shows the message "Printer has detected multiple consecutive filament loading errors. We recommend checking the extruder".

Error name: Maintenace failure warning

Error code: #28116 (MK3.5S) #23116 (MK3.5)

How to fix it? 

Follow the MMU3 regular maintenance guidelines and the regular printer maintenance guidelines, in particular those related to the extruder components.
