Hersteller: Nivona | Typ-/Modell: NICR 960 - Typ 698 CafeRomatica | ca. Baujahr: 2019

Hi. I have an error on my machine, it says error 12 and stopped. Only if i make coffe with milk.
I Think it has something with the stellmotor to do, but i don’t know where it is placed.
Any ideas or advices?

Thanks for the answer, I’m still not sure how to get there, but I will give it a try.

Hi again. I did not find it, Do you have a picture of your mashine, so I can see where it is?
Thanks and best regards
Anette

Thanks, but has anybody tried to pull that apart on the 1030?
Have anybody connected the mashine to the internet?

Hi sb_NUE

Thanks for your input, you are close to my situation. Here's what i found;

Fault/fehler/fejl 12

The milk frother in our Nivona 960 began to create new noises, and eventually stopped working, which gave a red ”Fejl 12” in the display. Sometimes you could reset the machine by the main switch and get lucky with a cup with not so ”foamy” milk, but something had to be done.

A danish workshop with relation to a dealer, could evaluate the machine for 500 Dkr, and make a repair offer. Today I am convinced that the total cost would end up in 2 – 3000 Dkr – ish. (3-400EUR)
So – on the internet for clues, which led to komtra.de

Not much about ”Fault 12” in a model 960 there, so I had to search for myself. After general cleaning in the main body shown on YouTube many places, I turned focus to the front, where an Antrieb für milchtemperatur is located.

You get access by removing the NIVONA cover below the display. Carefully remove the spout tubes and the four rubber seats for holding the cover. Deep inside you find four screws, and with these removed you lift the display up. Now you take pictures to make sure how to reassemble the unit again.

Remove the tubes and connectors except the one for the display. Carefully open four clips for the lid by the white motor assembly, and remove two screws for the motor.

Now you have the motor assembly which was the culprit here.
I opened it up and found a wormgear lubricated with a white substance, visible similar to wood adhesiveBison | White wood adhesive . Problem was that this lubrication also worked as an adhesive, because the axle next to the motor was almost stuck. This white stuff appeared very sticky and it took strong fingers just to rotate the axle.

The good news is that this explaines the Error 12, as it indicate a current limiter for the motor. As an electrical motor is prevented from working while it is powered, the current increases. If the circuit did not have this limiter, components might have burned and we would have a worse situation, so thank you Nivona for this electronic design. Besides the wormgear mechanism is full metal and not just plastic, so I found no damage to the gear.

I concluded that this white stuff must go. I unsuccessful tried different types of solvents, but ended up using a shorthaired brush for a while. Instead I lubricated the gear with another type of grease like you would use in for example a wiper motor for a car.
Finally all of this was reassembled and it was time for a cup of coffee. Tadaa – the machine worked perfectly with creamy foam and the right sound.

BTW – should you decide to buy a new motor. I recommend to open it before mounting, to see which type of lubrication is used. I am convinced that others will confront this issue as well.
