I've diagnosed your La Marzocco Linea Mini. There's a short circuit in the main power board, likely caused by water damage. Since this is a high-end machine, I'll need to order specific parts from the manufacturer.

That's concerning. Is this covered under warranty? And how long will the parts take to arrive?

Yes, this is covered under your warranty. I've placed the order for the parts, which should arrive within 5-7 business days. La Marzocco parts sometimes take a bit longer due to their specialized nature.
