Dolce Gusto coffee machine – red light blinking, won’t turn on?

Hello.
I have a Dolce Gusto coffee machine and I’ve been happy with it so far. Today it won’t switch on; the light is flashing red and won’t turn green. I like this machine, but I don’t know what to do. Perhaps someone could tell me if there’s a repair service. Thanks in advance, Marzena.

I am responsible for the Dolce Gusto service
You gave too little information .. You need to know what Dolce Gusto model is ...
Do you have a Torx T10 multimeter and screwdriver?
Ev. when you are from Warsaw, I can help you personally

We are also satisfied with the coffee machine, but after 1.5 years I have a problem with the Dolce Gusto Circolo model.
When turned on, it flashes red, and after a few seconds, it flashes red and green.

Has anyone had a similar case?

Please enter your Dolce Gusto model and I will be happy to help.
The model can be found on the bottom of the coffee machine and starts with the letters: KP ....

thank you for your willingness to help
the problem was solved after holding the button for a long time

Hello, I have dolce gusto piccolo genio manual and today I disconnected it from the power supply and after turning it on again the red light does not stop blinking. What could be the cause?
Help ! I am 2 months old

And the machine has no warranty?
From the description, I would bet on a damaged heater .. But there may be many reasons for this ..
It was necessary to start the coffee machine and check with a multimeter whether there is voltage to the heater ... and the transition of the heater, wires, etc.

Hello
The Dolce Gusto KP110 coffee machine does not heat the water. After switching on, the LED is red for 2-3 seconds, then it turns green as if everything was fine, I will add a new machine that has been used twice for a long time, it has been left unused.

99% switch to replace

Thank you for the diagnosis, where can I find such a switch?

To be honest, only repair at an authorized service is involved in the game ..

However, do not throw at the switch immediately and check the heater and the NTC sensor on the heater with a multimeter.

In my experience, this machine is unfortunately quite fail-safe. We bought one for my parents for their wedding anniversary, but before the warranty period expired, it was serviced three times. One time it did not warm up at all, although it reported that it was ready to work, other times it mixed up its functions, and the third time I do not remember. I was discouraged by this type and I would rather not recommend it. It is a pity that it was a gift, because it's hard to withdraw from it.

I have a KP1002 machine
It will flash red twice and the silence will turn green the next time and then it works

Hello.
I have had the same problem for several days ...
Red light flashes and does not turn green.
I undressed express anyone will advise what to check or measure?
Regards.

Flashing all the time? Or only twice and goes out?

Measure the heater and the NTC sensor

That's just how it flashes

nioop - which cables exactly to measure?

Probably brown and blue it will be a heater, the value of a few ohms is what I think. And on this large aluminum element (heater) there will be an NTC thermistor (temperature sensor) installed. Two thin wires, probably a few kilo ohms.

Brown and blue have current, the rest of the wires do not respond ...
I still made the zware on the two in the white circle in the picture and the pump works all the time when connected to electricity ...

It was you who played in checking the elements under the current?
A short circuit of the pump power supply probably damaged the triac on the electronic board.

how brown and blue can power the heater? From ancient times, these colors are used to describe power. Brown is current and blue is neutral.

Only two wires come out of the heater and to be honest I have never looked at what their colors are.
At the top of the heater there is an NTC from which two thin black wires come out.
But that's not the way ...
Please do not take me wrong, but if you want to play electronics, you cannot suggest "measure the red and green wires, then the blue and orange".
Repairing this type of device with basic skills and logical thinking is very simple .. But the heater will have a different resistance, and the NTC will have to be changed to a higher resistance to read something ..

At the moment, please deal with the triac that controls the pump operation.
It is connected centrally to the pump and you can track it without any problems .. There are many ways to check it on the Internet and the triac itself is a penny thing ..

I will dig up the topic a bit, because I also had an ailment with my "Krups KP1101"
When I turn it on at 230V, the red lamp will light up for 5 seconds and then it will turn to orange and blink all the time. It blinks a moment and turns off, nothing shines. After manually switching the lamp on, it is the same, i.e. the red one lights up for a moment, then the orange flashes and it turns off on its own. I was able to start the descaling mode a couple of times and it never got to the end. It turns itself off automatically in the hot water phase during descaling. I tried to repeat it several times but it always shut off at different times during the descaling process. Maybe someone had a similar problem and solved it, or maybe someone knows what may be damaged.

It looks as if the capacitors already have little "efficiency"

Capacitors on the power module? I'll check on Monday and let you know. I think the temperature sensor should be ok.

My coffee machine turns on, the red LED lights up as standard, then it flashes green 7 times, then it lights up constantly red, what could be the reason for this?

greetings

It would be appropriate to write what is meant by "my coffee machine"
It would also be appropriate to write what steps were taken, where the problem was encountered, or if you also intend to open the coffee machine and check it.
I am asking because I notice a big tendency - I will write on the forum, but I will send it to the website anyway

The coffeemaker is Dolce Gusto Circolo. I have it for about 7 years, it worked without any problems so far, about a month ago it was descaled. The symptoms described above appeared today. So far, I have not worked anything towards repair. I do not know what to do, is there a repair option or is the machine suggesting something with these light signals? can it be repaired?

Check if it gives voltage to the heater.
Check the heater itself and the two thermals on it. Possibly the ntc sensor (remembering that the ntc sensor should be checked at high resistance)
If it turns out that two thermals are damaged at the same time, you need to check the triac on the board. The one on the heat sink.
In case everything turns out to be okay, we'll keep looking.

Unfortunately, I do not attempt to brew this coffee machine, I do not have time or sufficient constipation, if someone is willing, I can give it back for shipping costs.

I join the discussion. I have had a dolce krups oblo machine type KP110 for over 1.5 years
When I turn it on at 230V, the red lamp will light up for 5 seconds and then it will turn to orange and blink all the time. It blinks a moment and turns off, nothing shines. After manually switching the lamp on, it is the same, i.e. the red one lights up for a moment, then the orange flashes and it turns off on its own. Unfortunately, I was unable to start the descaling mode. Is it worth repairing and what may the cost be?

There is a triac T835H-6I 8A, 600V, 35mA, 150C there, what to replace it with, I have a choice BTA 08-600C has 25mA, and BTA 16-800CW has 35mA and 16A, 800V?

Added after 7 [hours] 13 [minutes]:

I installed BTA08-600C, replaced 0.47uF 310V and 2 130C 10A thermal fuses and it works, including the oblo there is also a problem with the contacts on the switch, this lever, when turned to the right, often stops working, you need to correct the contacts because they disconnect!
