To change the main power fuse, unscrew the 10 top screws in order to remove the top panel.
The main fuse is located on the power supply unit PCB, as shown on the photo.
Turn the cap 90° to the left to open the fuse holder.
Replace the fuse with a new identical one (2 A T).
In case the fuse should blow again when you switch the power on, please contact a repair office.
Don't forget to unplug any external power supply and to empty the batteries compartment before any repair inside the mixer.
