Whether your morning cup of coffee is the motivational fuel that gets you through the workday or a cherished ritual that sets the tone for a relaxed weekend, there’s nothing more frustrating than finding your coffee machine on the fritz when you need it most. From blockages and leaks to electrical issues, there can be numerous reasons why your coffee machine is not working as expected. Fortunately, many common coffee machine issues are easy to diagnose and fix.

Common Coffee Machine Problems and Their Causes

1. The Machine Doesn’t Power On

If your coffee machine isn’t turning on, the first thing to check is the power supply[^1^]. Ensure the machine is plugged in and the outlet is working. If everything looks fine but the machine still won’t power up, it may have a blown fuse or a faulty power cord.

2. The Machine Doesn’t Brew

If your coffee machine is powering on but not brewing, the culprit might be a blocked water line or heating element. Mineral buildup from hard water can clog these components, preventing the water from reaching the right temperature or flowing into the brew basket[^2^].

3. The Coffee Tastes Bad

Poor-tasting coffee can result from a variety of issues, from using the wrong grind or coffee-to-water ratio to a dirty machine. Regular cleaning is crucial for maintaining the quality of your brew[^3^].

4. The Machine Leaks

Leaks usually indicate a loose connection or a faulty seal somewhere in your machine. The location and amount of the leak can help you identify the source of the problem.

How to Fix Your Coffee Machine

Before trying to fix your coffee machine, always consult the user manual and follow any troubleshooting steps provided by the manufacturer. Here are some general steps to resolve the common issues outlined above.

1. The Machine Doesn’t Power On

If your coffee machine isn’t turning on, try plugging it into a different outlet. If that doesn’t work, the problem could be more complex, and you may need to contact the manufacturer’s customer care team who will activate an alert to the relevant engineer or operative to visit the site and resolve the issue using remote fault tracking technology.

2. The Machine Doesn’t Brew

For a machine that doesn’t brew, start by checking for blockages. If you find any, clean the machine thoroughly, using a descaling solution if necessary. For bean-to-cup machines like the SMARTQUBE X series, ensure the beans are not over-packed and that the grinder is functioning correctly.

3. The Coffee Tastes Bad

If your coffee tastes off, try adjusting the grind size or the amount of coffee you use. Also, ensure you’re using fresh, good-quality beans or grounds. A regular cleaning schedule can help maintain the quality of your coffee.

4. The Machine Leaks

If your machine is leaking, try to identify where the leak is coming from. Tighten any loose connections, and if you suspect a faulty seal, contact a professional.


Dealing with a malfunctioning coffee machine can be frustrating, but with a bit of troubleshooting, many common issues can be resolved quickly. Regular maintenance, like cleaning and descaling, can prevent many problems before they start.

If you are looking for quality coffee machines for your home or office, companies like Refreshment Systems offer a range of options, from bean-to-cup machines to traditional barista-style machines. Furthermore, they also provide maintenance and repair services, ensuring that your coffee machine remains in optimal working condition.

However, always remember that this guide is intended to provide general advice. Always consult with a professional for issues related to your specific coffee machine model.

I think the most important advantage RSL had over other potential suppliers was the use of the mobile drinks van. We knew we were getting quality before we switched suppliers!

Refreshment Systems are brilliant, I thought getting vending and coffee machines for our company would be complicated and time consuming, I was totally wrong, from the minute I called and spoke with Frazer I felt confident they could supply what we needed.
