4 Reasons Why Your Delonghi Coffee Machine Blocked
1. Limescale Buildup
One of the most common causes of a blocked Delonghi coffee machine is limescale buildup.
Using hard water can cause limescale, which contains high levels of calcium and magnesium. It typically appears as white deposits on the internal components of your Delonghi coffee machine. Such as the filter holder or portafilter handle.
Over time, these deposits can accumulate and cause blockages in the system. To prevent this from happening, you should regularly descale your Delonghi coffee machine using a descaling solution or vinegar solution.
2. Clogged Filter Basket
Another common cause of a blocked Delonghi coffee machine is a clogged filter basket. The filter basket collects grounds from the beans that we use to make your espresso shot, and over time these grounds can accumulate and cause blockages in the system.
To prevent this from happening, you should regularly clean out the filter basket with hot water or an espresso cleaning brush. This will help keep your Delonghi coffee maker running smoothly.
3. Grounds in Group Head
If you don’t use a good coffee brand subscription. The group head (the area where you insert the portafilter) can also become clogged with grounds over time if not properly maintained.
When too much ground accumulates in the group head it can cause blockages in the system. To prevent this from happening, make sure to clean out the group head after each use with an espresso cleaning brush or hot water. This will ensure that you removed all grounds before brewing more espresso shots.
4. Blocked Water Lines
Finally, if your water lines become clogged with mineral deposits it can lead to problems with water flow and eventually blockages in your system.
To prevent this from happening you should regularly flush out your water lines using an approved cleaning solution or vinegar solution every few months. Keeping your lines clean will assist in preventing clogs over time.

Then, remove the filter basket and clean out any grounds or debris that may be clogging it.

Delonghi Dedica Clogged Pump – Fixed
If you’ve got a clogged pump of the Delonghi Dedica, there are several things you can do to fix it.
First, make sure the water tank is full and not too low.
Next, check for any blockages in the hose leading from the tank to the pump assembly.
If there is a blockage, try using a thin wire or pipe cleaner to clear away any debris that could be causing an obstruction.
Finally, if all else fails, try cleaning out the pump assembly itself. You can do this by unscrewing and removing any parts of the pump assembly.
If possible, remove any debris that might be blocking its path (such as filters) and then brush it away.
Delonghi Coffee Machine Low Pressure
If your Delonghi coffee machine isn’t producing enough pressure when making espresso shots or cappuccinos, there are several potential causes:
Make sure your machine’s brew group is properly cleaned; over time. Hard water mineral deposits can build up in this area and reduce water pressure significantly.
If this is not an issue, then it’s possible that your machine needs new gaskets (or O-rings) installed in order to generate more pressure.
These gaskets tend to wear down over time due to the frequent use of hot water inside the machine’s boiler chamber. Installing new gaskets will likely require assistance from an authorized service technician.
