Coffee Machine Clogged Nozzle

A clogged nozzle is one of the most common coffee machine faults. Dried milk residue and coffee oils build up inside the narrow outlet and gradually block the flow of steam and hot water.

⚡ TL;DR — Quick Answer

Soak the nozzle in hot water with a drop of dish soap for 10 minutes, then clear the opening with a pin and rinse.

Understanding Clogged Nozzle

The steam and hot-water nozzle is a narrow passage that milk proteins and coffee oils pass through at high temperature. Over time these residues dry and harden inside the tube, restricting flow until the machine splutters or delivers nothing. Regular rinsing after every milk drink is the simplest prevention.

Universal Troubleshooting Steps

These steps work across all major brands:

  1. Remove the nozzle or frothing tip following your machine manual.
  2. Soak it in hot water with dish soap or a descaling solution for 10-15 minutes.
  3. Clear the opening with a pin or nozzle-cleaning needle, never a metal tool on coated parts.
  4. Rinse thoroughly, reattach, and run the steam function for 30 seconds to flush the line.

Frequently Asked Questions

After every use with milk. A 10-second steam purge keeps the passage clear.

Only if the manual allows it. Most frothing tips are better washed by hand to avoid residue in hard-to-reach corners.

Spluttering usually means a partial blockage or water in the steam line. Clean the nozzle and purge the wand.

Soak it longer in a descaling solution, then check the steam wand tube itself for dried milk further up the line.

Yes. Limescale combines with milk residue and hardens faster. Use filtered water and descale regularly.
