error 1 grinder block on Lyrica

[espressotech]

Hello
board type 1.9.30.231.00_v01
what component gives current to the grinder?
in case of failure and error 1 when grinder is not actually block and new motor and grinder sensor card is installed
Thank you
Guy

Check all Resistors

 

[espressotech]

thank you, checked 113Ω in every resistor

 

[uhrmacher]

Is the big 4.7 ohm ceramic ok too?

 

[espressotech]

Is the big 4.7 ohm ceramic ok too?

Do you mean f1 ,f2 fuse ?it seems ok there is continuity, what is 4.7 Ω mean? I also checked grinder under current there is 60v dc and when I press to make espresso it go170v , 208 v for a second and go back to 60 v nothing happen . for some reason I cannot access test mode
I succeed once with menu+coffee+turn on and it was the same grinder show 0

I meant the big ceramic resistance with 4.7 ohms. It is located directly in a row to the mill engine and when it is burned. the mill is blocked. The mill motor must start with externally connected 12V DC voltage.

 

[espressotech]

@uhrmacher I do not know what resistor you mean can you share picture and or code on the board?

 

[espressotech]

@uhrmacher these? give 12.2Ω each

[espressotech]

@uhrmacher seems ok 10.6Ω

 

[uhrmacher]

10,6 Ohm is not OK 4,7 Ohm

 

[espressotech]

not ok even with resistor connected to the board?

 

[uhrmacher]

Not OK, it must be 4.7 ohms even when installed.

 

[espressotech]

@uhrmacher i checked again before replacing now it is 4.9Ω. I guess it was influence of capacitors

 

[uhrmacher]

Then he's okay
Connect a 230V light bulb to the two connections of the grinder motor and see if it lights up briefly when the grinder is started.

 

[espressotech]

@uhrmacher yes there is light for a second and than error 1
the machine also not entering test mode

 

[uhrmacher]

Do I understand that correctly, you have installed a new motor and it does NOT turn, not even for a short time, but the lamp lights up briefly?

 

[espressotech]

yes correct I tried 3 motor and 3 sensors manically with dc they turn but not when connected to board

 

[uhrmacher]

Dann kann er den Sensor nicht lesen, ist dessen Stecker richtig gesetzt?

 

[espressotech]

I think so there is not other option to connect it, and other side to the board
