Breville Barista Pro Steam Coming from Bottom – 2 Main Reasons and 3 Easy Solutions

For all the espresso lovers who love to consume frothed milk along with their favorite cup of coffee, the steam wand holds significant importance.

It not only steams the milk to prepare foam but gives it a tasty flavor too.

It makes your coffee tastier and more flavorful than ever before.

Breville Barista Pro is often considered the best espresso machine that froths the milk and gives it the desired texture to make your espresso consumption even more delicious.

If you do not know, milk frothing is the process of thickening milk using heat pressure and giving it a foamy texture.

People often use it to consume with their cappuccino or espresso coffee cup to give it an extra texture and creamy and foamy flavor.

But being a machine, it does not always go the way you want.

Sometimes, it might make things worse for you.

In this article, I will be covering a frequent issue that many Breville Barista Pro users have faced and reported.

I will mention 2 main reasons why the steam leaks from the bottom of Breville Barista Pro coffee machine and will also provide 3 simple remedies for them.

In my extensive research, I have found out that the machine sometimes leaks steam from the bottom and makes some irritating noises as well.

It not only makes the frothing process just worthless but also makes an annoying experience for you.

Just think of steaming milk for your morning coffee in a sugar factory.

Horrible, am I right?

One major cause for your Breville Barista Pro leaking steam from the bottom is the blockage in the steam wand holes.

When any of the holes are blocked, completely or partially, it causes high pressure on the steam wand.

As a result, the machine leaks steam from the drip trays at the bottom.

An easy fix for this issue is to eliminate the blockage in the holes.

You can clean the steam wand using a steam wand cleaner or any other similar cleaning tools as well.

Once you remove the blockage, the machine will be again ready to froth milk for your espresso without making any fuss.

I will mention other important reasons further down the article.

So, I hope you will read this entire article till the end to understand the main issues and their solutions as well.

2 Main Reasons Why Your Breville Barista Pro Leaks Steam from Bottom

Well, there is not only a single cause for the Breville Barista Pro espresso machine steaming from the bottom.

There are several other reasons as well.

Below, I have gathered 2 important reasons for the issue after doing the deep research.

The below mentioned are the major reasons that are causing steaming issues in your Breville Barista Pro espresso machine.

Reason 1: Insufficient Hot Water in the Machine

One possible reason why your Breville Barista Pro is leaking steam from the bottom is the insufficient amount of hot water coming from the machine.

We all know how steam is formed, by heating water, right?

That’s the same process in the Breville Barista Pro machine.

The machine carries out the hot water to its water tank.

After that the thermostat converts it into steam and then completes the frothing process.

But what if the machine doesn’t carry enough hot water to the water tank?

It won’t make enough steam and the extra pressure will cause steam leaking from the bottom. 

This is the problem here.

And because of the same reason, the machine makes irritating noises as well.

Reason 2: Trapped Air inside the Water Tank

In the other case, air might be getting trapped in the water tank of your Breville espresso machine.

This trapped air then causes the steaming issue.

If it is so, it obstructs the water supply process.

This eventually cause steam leaking from the drip tray along with making some unusual noises.

If none of the above solutions work for you, then descaling your coffee machine can be the best idea.

Why is My Breville Barista Pro Steam Wand Weak?

A weak steam wand can ruin the whole milk-steaming process or the milk frothing process.

Just think if the milk is not frothed enough and has a bad texture, then what will happen?

Would you use it with your coffee or espresso?

Would it give the same taste and flavor as it did after the proper steaming?

No, it won’t.

When you steam or froth milk with a weak steam wand, the poorly textured milk can just ruin your coffee taste and flavor.

But why is your coffee machine’s steam wand weak?

Well, it can be due to blockage in the holes present inside the wand.

The steam wand might get blocked completely or partially due to coffee particles and oil residue.

This leads to weakening of the steam wand.

To fix the issue, you need to clean the steam wand properly using a steam wand cleaner.
