Cafetera Delonghi EN95. R, pushing down the on button, the two green lid lights are dim. Pay attention as this data is important, if it has these problems, it may be caused by a fault of the condenser which is the purpose of this report.

SUMMARY: CAFETERA NESPRESSO Takes time to heat up or button remains flashing dim lights. In this guide I will focus on how to change the condenser of 680 mf/275V which affects both the button and heating for the water in the boiler.

We remove the case on the right with a screwdriver TORX T9, We begin to see the two screws which connect the electronic module to the chassis.

For better work it’s recommended to lay the machine down.

We extract the electronic module and open up the lid.

Here we have the PCB in sight, our problem in 95% of cases is that the buttons are turned on, the fault is located in the center of the condenser, the one bigger in size.

To come up with the measurement, we slightly separate the condenser from the PCB and short circuit its terminals with a pair of scissors and a screwdriver BEFORE we measure it, so we don’t damage the measuring apparatus with residual voltage

Testing with a capacitance meter, a 680 nF condenser measures 315 nF in this case. Clearly, it is faulty, under capacity, and it must be replaced.

Confirming that it is damaged, we proceed to replace it. We will cut the other terminal of the condenser

ALWAYS test the replacement, especially if it is recycled or reused from another PCB.

Once you’ve replaced the condenser, lift the machine, connect the network cable and check if the buttons light up bright green. Machine repaired.

This is just an exhibit, as general culture, if the problem is not solved replacing the large 680 nF condenser, replace in 2º the small one, and if the problem persists, the last option is the 3º electrolytic, but I don’t think it will come to this.

At last, position the PCB in its location, take the cover and screw it on
