Question about Coffee Makers & Espresso Machines
Milk gets sucked into the boiler when the boiler rapidly cools and creates a vacume while your steaming milk. this can be caused by water inlet problem involing the level probe inlet valve or level board. there is also an anti syphon valve that is built into the overpressure relief valve that could be malfunctioning.

Unless you have milk hooked up as a water supply to your machine there's no way milk can get into the boiler. It's probably due to your water supply. Do you use filtered water? I would suggest pulling the boiler and flushing it with Scale Kleen and cleaning the unit.
