Hello fellow vivaldi owners!
Im descaling my vivaldi s1 steam and brew boiler as well. As i was looking for some pictures how to do it i noticed that my machine doesnt have a triac cooler fan on the bottom right of the machine. I found an identical fan in a local shop however it is without a connector. Can anyone help me out what size of connector do i need to connect the fan to the board. ( on the picture is what im looking for :)) Thank you in advance!

From what I have read, Prague uses 220VAC. The S1 Fan is only needed in 110VAC countries. This is because at 110VAC, twice as much current flows through the triac compared to 220VAC systems. Triac boards don't get hot enough at 220VAC to need a fan.

In both machine types, the steam boiler draws 1440Watts:
I=P/V = 1440/110 = 13.09 Amps @ 110V
= 1440/220=6.55 Amps @ 220V
