In that case, you can use a flat head and pry it off from the machine.

After that, I recommend to use company recommended Gaggia Descaler Solution to get the best cleaning results.

With this descaling solution, you will be able to remove the stuck group head of the Gaggia Classic machine.

2 Reasons Why Group Head of Gaggia Classic Coffee Machine Gets Stuck

Reason 1: Buildup of Scale and Debris

If you do not clean the group head for an extended period, then the scale will start building up inside the group head and gasket.

Consequently, the group head will get stuck there, and it will be pretty challenging to remove it from there.

Even if you use flat head or other equipment, it will still be tough to remove the stuck group head due to thick layers of limescale and other debris collection.

Problem 2: Gasket is Broken

There is rubber gasket present inside the group head which can also get stuck or damaged.

If the machine’s group head is not opening properly, then it is possible that the gasket gets jammed over there after it is broken.

After this, it will be pretty hard to remove the group head from its stuck position.

5 Steps to Remove Stuck Group Head of Gaggia Classic Espresso Machine

When the group head of your Gaggia Classic machine gets stuck, then it is a bit hard to remove that group head.

Here, I am going to explain the few steps that will help you comfortably remove the stuck group head from the machine.

You will also know how to remove the stubborn screw that holds on your shower screen, how to get out a persistent shower screen holding plate, and how to remove the group gasket.

It is not that hard to do the above troubleshooting if you have the right stuff and the right knowledge about it.

Step 1: First, you will have to use your Gaggia Classic machine when it is not hot and has normal temperature.

Then, take off all the machine components because you will have to turn the machine upside down.

So, you will need to take off the tube, the drip tray, the little cover on the top, and the water reservoir.

Step 2: Now, turn the machine upside down so that you can work on it quickly.

You will need to remove the screw first.

Make sure the screw is clean.

You can use a longer shafted screwdriver that can fit the screw well.

Press it hard when turning, and then remove the shower screen.

Step 3: After that, you will get a shower screen holding plate.

It comes with a 5-millimeter Allen wrench.

Always make sure that it is clean.

Then, turn those screws out.

Opening them can be a little tricky if you had never done this before and had been using Gaggia Classic machine since last few years.

Step 4: Now comes the group head.

The stuck group head won’t come out easily in several cases.

To get it out, you will have to use leverage, take a screwdriver, and just keep wrenching on this.

You may go from side to side, just put a little force on that, and eventually, this will come out.

When the group head comes out, clean it properly.

Step 5: Next thing to take care is the group gasket.

This gasket wears down over time, so you must replace it once you see it is broken or damaged.

Once the parts are removed, you can use a Gaggia Descaler Solution and brush to completely clean and descale the group head.

You can now soak all the elements in the descaler to remove the scale built over time.

You can use the backflushing method to clean the group head from time to time.
