How to Descale a Home Espresso Machine

We recommend descaling your espresso machine every few months under normal usage, but you may have to perform this more frequently if your water has a high mineral content. Note: Please be sure to collect the used descaling solution in a container, as the citric acid in it can tarnish metallic components.

The following are recommended descaling instructions for general types of espresso machines. Please consult your machine user manual for specific instructions on descaling your particular machine.

Descaling a Single Boiler or Thermoblock Espresso Machine

  1. Dissolve the descaling agent into a full water reservoir.
  2. Pull the solution into your boiler by running about a cup of water out of your steam and/or hot water wand. Close the steam knob.
  3. Turn off the machine and let sit for 20 minutes. This is important to allow the descaling solution to work.
  4. After 20 minutes, run about 1/4 of the reservoir out of the steam wand, 1/4 out of the brew head.
  5. Turn off the machine and allow to rest for another 20 minutes.
  6. Flush the remaining water out of the steam wand and brew head, and finish by running a reservoir (or two) of clean water through the machine.

Descaling a Superautomatic Espresso Machine

If your machine has an automatic descaling cycle, refer to the owner's manual for instructions. For machines without an automatic descaling cycle:

  1. Dissolve the descaling agent into a full reservoir.
  2. Pull the solution into your boiler by running about a cup of water out of your steam wand. Close the steam knob.
  3. Turn off the machine and let sit for 20 minutes. This is important to allow the descaling solution to work.
  4. After 20 minutes, run about 1/2 of the reservoir out of the steam wand.
  5. Turn off the machine and allow to rest for another 20 minutes.
  6. Flush the remaining water out of the steam wand and finish by running a reservoir of clean water through the machine.
