5 Surprising Reasons Why Your Espresso Machine Isn’t Building Pressure (and What To Do About It)

If you’re wondering why your espresso machine isn’t building pressure, the first thing you should check is your group head. A clogged group head can prevent water from flowing through your machine properly, preventing it from building pressure. To clean your group head, use a brush or pipe cleaner to remove any buildup. If that doesn’t work, you may need to descale your machine. To do this, use a descaling solution according to the manufacturer’s instructions.

Why Is My Espresso Machine Not Building Pressure?

So, you bought yourself an espresso machine and now you’re wondering why it’s not building pressure. That’s a bummer, but don’t worry, there are a few steps you can take to troubleshoot the problem.

First, check to make sure the water tank is full. If it’s not, the machine won’t be able to build pressure properly. Next, take a look at the water filter. If it’s clogged, the machine won’t be able to draw enough water to build pressure.

If neither of these issues seems to be the problem, the next step is to check the pump. The pump is responsible for building pressure in the machine, so if it’s not working properly, the machine won’t be able to build pressure.

To check the pump, you’ll need to remove it from the machine. Once it’s out, use a multimeter to test it. If the pump is working correctly, you should see a reading of around 12 volts. If you don’t, you’ll need to replace the pump.

If the pump is working correctly, the next step is to check the pressure switch. The pressure switch is responsible for telling the espresso machine when to build pressure. If it’s not working properly, the machine won’t be able to build pressure.

To check the pressure switch, you’ll need to remove it from the machine. Once it’s out, use a multimeter to test it. If the switch is working correctly, you should see a reading of around 1.5 volts. If you don’t, you’ll need to replace the switch.

If the pressure switch is working correctly, the next step is to check the solenoid. The solenoid is responsible for telling the espresso machine when to release pressure. If it’s not working properly, the machine won’t be able to release pressure.

To check the solenoid, you’ll need to remove it from the machine. Once it’s out, use a multimeter to test it. If the solenoid is working correctly, you should see a reading of around 1.5 volts. If you don’t, you’ll need to replace the solenoid.

If none of these steps solve the problem, it’s possible that the espresso machine’s internal components are damaged. In this case, you’ll need to take the machine to a professional for repair.

In conclusion, if your espresso machine is not building pressure, there are a few steps you can take to troubleshoot the problem. If these steps don‘t solve the problem, it’s possible that the espresso machine’s internal components are damaged. In this case, you’ll need to take the machine to a professional for repair.

What Are The Common Causes Of Low Pressure In An Espresso Machine?
