The problem of water leaks is not exclusive to the Delonghi brand or its Eletta model; it is common to all coffee makers. The most frequent leaks that can occur are the coffee infuser area and the machine’s base.
Water leaks are, in addition to being uncomfortable, a problem that can end up affecting the amount of water that comes out to prepare coffee, decreasing the flow and even blocking it completely. Before these leaks cause damage to other parts inside the coffee maker, pay close attention to this problem.
The problem: Our Delonghi Eletta Cappuccino coffee maker leaks from the front, just behind the coffee spouts, and the drip tray overflows with water.
The cause: The O-rings in the internal connections of the machine, with time and the use of the coffee maker, tend to wear out or get damaged, often being responsible for causing water leaks.
A leak produced by the damage of a gasket will be easy to identify, but others are less visible, such as those that occur inside the piston valve of the coffee generator group.
The solution: Start by turning off and unplugging the coffee maker before disassembling it; once the coffee maker is dismantled, locate the piston of the infuser and disassemble the valve attached to it (picture above). Check each valve component until you find the damaged gasket and replace it.
If you also notice that the piston structure is damaged, you will have to replace it. Clean each of the parts you removed very well and put the piston of the coffee generator group back into the coffee maker. Finally, reassemble the entire machine.
