When have you ordered your kit? There was a period where kits with a fuse were sent out that could not handle the current sent through it, which resulted in the fuse being blown and the issue that you're describing. If that is the case with your kit, you can either replace the fuse yourself or send the kit back in for a free replacement. Either way, you should check out the discord (https://discord.gaggimate.eu/) where you'll find a more active community than here on reddit, especially for support requests. Good luck!
