What To Know
- A malfunctioning or clogged breather valve can cause water to leak from the top of the machine.
- In some cases, a leak can be caused by a blockage in the machine’s internal plumbing.
- A leak from the bottom of the machine is often caused by a loose or damaged water tank, worn O-rings, or a clogged internal blockage.
If your once-reliable Breville coffee machine has started springing leaks, don’t panic. This common issue can be caused by several factors, and with a bit of troubleshooting, you can get your morning brew back on track. Here’s a comprehensive guide to help you identify and fix the source of the leak:
1. Loose Water Tank
The water tank is the primary culprit behind leaks in Breville coffee machines. Ensure that the tank is securely attached to the base and that the lid is closed tightly. A loose connection can allow water to escape, resulting in a messy leak.
2. Damaged Water Tank
Inspect the water tank for any cracks, chips, or other damage. A compromised tank can leak water even when properly attached. If you find any damage, replace the tank to stop the leak.
3. Clogged Water Filter
A clogged water filter can restrict water flow and cause pressure to build up inside the machine, leading to leaks. Regularly clean or replace the water filter to prevent this issue.
4. Faulty Breather Valve
The breather valve is a small component that helps regulate pressure inside the machine. A malfunctioning or clogged breather valve can cause water to leak from the top of the machine. Clean or replace the breather valve to resolve the leak.
5. Worn or Damaged O-Rings
O-rings are rubber seals that create a watertight connection between different components in the machine. Over time, O-rings can become worn or damaged, allowing water to leak. Replace any damaged O-rings to stop the leak.
6. Loose Fittings
Check all the fittings and connections in the machine, including the portafilter and the group head. Loose fittings can create pathways for water to leak. Tighten any loose fittings to eliminate leaks.
7. Internal Blockage
In some cases, a leak can be caused by a blockage in the machine’s internal plumbing. Mineral deposits, coffee grounds, or other debris can accumulate and restrict water flow, causing pressure to build up and lead to leaks. Run a cleaning cycle or descale the machine to remove any blockages.
Troubleshooting Tips
- Reset the machine: Unplug the machine for a few minutes and then plug it back in. This can reset the machine’s internal components and potentially stop the leak.
- Check for leaks when the machine is idle: Turn on the machine and let it run for a few minutes without inserting a portafilter. If there is a leak, it will be easier to identify the source.
- Use a flashlight: Shine a flashlight into the machine’s interior to look for any visible leaks or water droplets.
- Contact Breville support: If you are unable to identify or fix the leak yourself, contact Breville customer support for assistance.
