Learn how to diagnose problems with the solenoid valve, plus clean and replace it if needed in the Gaggia Classic Pro.
Getting no water flow from the group head but have flow from the steam arm? If so, your solenoid valve may be blocked with scale deposits or malfunctioning in some other way. This detailed video takes you step by step through accessing the solenoid valve, cleaning it, and replacing it if necessary.
Most of the time, solenoid valve problems are caused by scale build up inside the boiler or valve itself. It's also possible that, while descaling your machine, chunks of scale broke off and got stuck in the solenoid valve.Â
If either of these issues is what's causing the problem, a simple cleaning of the solenoid valve should return your machine to good working order.Â
If cleaning the solenoid valve DOES resolve the issue, it MAY still become clogged again if you have additional scale still in the boiler. So, if the machine clogs back up in a few days, that doesn't mean that the solenoid valve has failed; it means you would need to do the full teardown and deep cleaning of the boiler.
