3 Key Reasons for Breville Espresso Machine Making Loud Noise

Reasons for Breville Espresso Machine Making Loud Noise

If your Breville espresso machine is making a loud noise, it can be quite disruptive to your morning routine or peaceful coffee time. Here are the most common causes of loud noise in a Breville espresso machine:

1. Grinder Problems

Breville espresso machines are known for their high-quality performance, but sometimes, they may start making loud noises, which can be an indication of grinder problems. Addressing these issues promptly can help you enjoy a smoother and quieter brewing process.

Faulty Grinder Components

If the espresso machine is making loud noises, it could be due to faulty grinder components. Over time, the burrs in the grinder can wear out, leading to uneven grinding and consequently, a louder grinding noise.

Improper Bean Grinding

Another common cause of loud noises in Breville espresso machines is improper bean grinding. If the beans are not ground to the right size, it can put excessive strain on the grinder, causing it to produce loud and disruptive sounds.

Here’s a quick fix guide:

  • Clean the grinder: Regularly remove coffee grounds and oil buildup from the burrs and hopper.
  • Adjust grind size: Use the dial to select the appropriate grind for your brewing method (espresso requires a finer grind than drip coffee).
  • Replace worn burrs: If cleaning doesn’t solve the issue, consider replacing the burrs, which can wear down over time.

2. Pump Issues

If your Breville espresso machine is making a loud noise, it could be indicative of pump issues. The pump is a crucial component responsible for creating the necessary pressure to brew an espresso.

Breville Pump Issues

Water Flow Problems

If the pump is making a loud noise and there’s a noticeable decrease in water flow, this could signify a clog in the pump or an issue with the water supply. To address this, begin by checking the water reservoir for any blockages. Next, ensure that the water supply is unobstructed.

Airlock Troubles

Airlocks within the pump can lead to disruptive loud noises. Firstly, switch off the machine and allow it to cool down. Then, initiate a manual priming process by running the pump to eliminate any trapped air.

Here’s a quick fix guide:

  • Check the basics: Ensure the water tank is filled and properly inserted. Look for any blockages in the water inlet or filter.
  • Run a cleaning cycle: Most Breville models have a built-in cleaning function. Refer to your manual for instructions.
  • Prime the machine: If you suspect an airlock, try running hot water through the steam wand for a few seconds to purge trapped air.
  • Descale regularly: Mineral buildup can restrict water flow. Descale your machine according to the manufacturer’s instructions and frequency recommendations.
