Another Brewunit Block

[P.Viby]

It all started with that I had to open the machine because the machine could not steam anymore. I fixed it actually by decalcifing and cleaning the steam system.

Since I had the machine opened I though I would clean also the grinder and brewunit. When I was about to put it all together again. I started up the system and it now comes up with brewunit block. The brewunit seems fine, it is not stucked or anything.

I have tried to bypass the 3 swithes (waste box, brewunit and access led to brewunit) and even without the brewunit installed it still does not turn the brewunit motor.

I have googled around and some forums talk about a service menu you can enter and recalibrate the motor limits ??

Any help from you super users ?

Thanks in advance

Check the resistance (range 200 Ohms) between "yellow-yellow" at 4-pole motor connector (yellow-yellow-red-blue) - disconnect mains before !

HEHE..Okay

I had the cupheater panel disconnected all the time during my work. The yellow-yellow goes to that panel. Makes absolutly no sense to me it then comes with a Brewunit Block message when this cupheater heating panel is disconnected.

Anyway connected the heating panel again and it worked.

BIG thank you for the help

Hi,

Look at the diagram of the brew unit circuit in this file -->> Saeco Getriebemotorregelung ---- Autor: hmilbradt ... and you will get an idea how it works.

Yep, Thanks. That shows it clearly how and why these are connected.

I just got fooled by the brewunit block message
