4 Main Reasons Why Gaggia Classic Machine’s Steam Wand Leaks

Reason 1: Worn out O-rings

O-rings are located inside the steam valve and provide sufficient pressure for the hot water.

The company recommends to replace these O-rings on an annual basis.

However, you need to check them often for their possible wear and tear.

When you notice damage of O-rings, then it causes steam wand to start leaking.

Reason 2: Broken Steam Valve

Another reason why the steam wand is leaking could be due to a worn-out steam valve.

A steam valve could be broken or damaged due to several reasons such as calcium buildup over the years and a damaged seal.

In that case, you need to replace the steam valve to stop steam wand leaking of Gaggia Classic machine.

Reason 3: Steam Valve not Closed Properly

The steam wand also starts leaking when the steam valve is not tightly secured in its place.

This is one of the most common reasons behind steam wand leaking.

Because constantly using your espresso machine can lead to loosening of the valve bolts and they need to be retightened again.

This can lead to your steam wand leaking later on.
