Descaling Breville Barista Pro

The water used to brew espresso causes mineral buildup inside your Breville Barista Pro. While not toxic, this buildup can impact the machine’s water flow, temperature and overall performance. It can negatively affect the taste of your shot of espresso too. Descaling Breville Barista Pro machines regularly removes these mineral deposits to extend its life. Keep reading to find instructions on how to descale Breville Barista Pro machines using a safe descaling solution.

How Often To Descale Breville Barista Pro

In addition to regular cleaning, your Barista Pro needs to be descaled every 3 months. The Breville Barista Pro has an LCD display that will show a DESCALE alert to remind you that descaling is needed.

You need to descale whether you are using filtered water, bottled water or tap water with a low to normal mineral count. You will need to descale more often if your tap has “hard water.” That means it contains higher level of minerals. If you are not sure about the level of minerals in your water, you can always get a low-cost water testing kit.

You should also descale if you are having any of these issues with your Breville Barista Pro:

  • Produces a lot of steam while brewing
  • Runs for extended periods with only steam output
  • Does not use the full amount of water in the water tank
  • Brews slowly

Can You Descale Breville Barista Pro With Vinegar?

You should not use water and vinegar solution to descale Breville Barista Pro machines. White vinegar contains 5-8% acetic acid. This type of acid can wear down stainless steel and cause your machine to leak. Plus, vinegar cannot remove oils left by used coffee beans.

Instead, the best way to deep descale your espresso maker is with one of the below commercial solutions. They have safe and effective types of acids that won’t damage your machine.
