why is my delonghi automatic espresso machine making loud bubbles in the milk froth?

You're likely using milk that's not cold enough or is the wrong fat content.

Here's what to do:

1. Use milk straight from the refrigerator, ideally around 41°F or 5°C.
2. For best frothing, use skim or 2% milk.

If you're doing that and still get big bubbles, try a different brand of milk. Some brands just don't froth as well in these machines.

Also check: Is your cappuccino maker clean? Residue can ruin froth. Make sure to clean it after every use by removing it and washing all parts.

Heads up: Always start with cold milk and a clean system for consistent microfoam.
