Some gurgling is normal as water moves through the system, but loud gurgling usually means an air lock or blockage. Here's what to do:

1. Unplug the machine and let it cool.
2. Check the water reservoir for any debris or scale flakes that could clog the inlet.
3. Check that the basket and filter are correctly seated. A misaligned basket can cause turbulent water flow.
4. Run a clean water cycle (no grounds) to see if the sound persists. If it does, there may be a partial clog in the internal tube. You can try a more thorough vinegar descaling cycle. If the loud noise continues after cleaning, the internal water pump or valve may be failing.
