Breville Barista Pro Steam Coming From Bottom: How To Fix?

The Breville Barista Pro is a popular espresso machine loved by coffee enthusiasts for its convenience, performance, and quality. 

However, like any machine, it can occasionally run into problems. One such issue is steam coming from the bottom. 

This post will explore the reasons behind this issue and provide step-by-step instructions on how to resolve it.

Understanding Your Breville Barista Pro

Before diving into the issue at hand, it’s essential to understand how your Breville Barista Pro works. 

The machine uses a ThermoJet heating system to heat water rapidly and create steam for frothing milk. If you notice steam escaping from the bottom, it’s a sign that something is amiss.

Why Is Steam Coming From The Bottom?

There could be various reasons why your Breville Barista Pro is leaking steam from the bottom:

  1. Loose Connections: Over time, the connections inside your machine might become loose due to regular use, causing steam to escape.
  2. Worn Out Seals or Gaskets: Seals and gaskets prevent steam and hot water from leaking. If they’re worn out or damaged, you might notice steam coming from the bottom.
  3. Cracks in the Water Tank: A cracked water tank can cause water to leak onto the heating elements, creating steam.
  4. Overfilling: Overfilling the water tank or the drip tray can lead to leakage and subsequent steam.

Step-By-Step Guide To Troubleshoot And Resolve The Issue

Step 1: Check For Loose Connections

Ensure your machine is turned off and cooled down. Open the machine’s casing carefully (refer to your user manual for guidance). 

Inspect the internal parts for any loose connections, especially around the boiler and steam wand. Tighten any loose connections you find.

Step 2: Inspect Seals and Gaskets

Check the seals and gaskets inside your machine. They should be flexible and snugly fit. If they’re hard, brittle, or ill-fitting, they need replacement. 

Order the right parts from Breville or a trusted supplier and replace them following the manufacturer’s instructions.

Step 3: Look for Cracks in the Water Tank

Inspect your water tank for any cracks or damage. If you find any, you’ll need to replace the tank. While waiting for the new tank, avoid filling the current one to the brim to minimize leakage.

Step 4: Avoid Overfilling

Ensure you don’t overfill the water tank or the drip tray. Always follow the manufacturer’s guidelines on filling the water tank and empty the drip tray regularly to avoid overflow.

Step 5: Seek Professional Help

If you’ve tried all the steps above and still see steam coming from the bottom of your Breville Barista Pro, it’s time to seek professional help. Contact Breville customer service or a professional appliance repair service.

Preventive Measures To Avoid Future Issues

To prevent issues like steam coming from the bottom of your machine, here are some preventive measures:

  1. Regular Maintenance: Regularly clean and descale your machine to keep it running smoothly. Pay particular attention to seals and gaskets during cleaning.
  2. Use Quality Water: Using filtered or bottled water can reduce mineral buildup inside your machine, prolonging the life of its components.
  3. Handle With Care: Handle all parts of your machine gently, especially the water tank, to avoid causing cracks or other damage.
