Question about Saeco Vienna Espresso Machine
Saeco primea ring stays on message "warming up please wait" will not come out of that message. Is there a reset button or reset option? I tried the menu reset to factory settings, but no change.
I had the same problem and could solve it but i had take the machine apart.
Under boiler you have 2 thermo fuses that can be resetted. After reset i have checked if boiler get 220volt, It did for a short while but the fuses goes off again.
That means boiler is ok, it gets hot but fuses goes of due to temperature reach over 170 degrees celcius. That means that the power is olways on to the heater and doesnt stop to heat.
In diagnostic i could see that the temperature sensor does show the high temperature. That means that temp. sensor is ok which leads to the controller of the power to boiler. On the board i found big heatsink and a triac atached to it. I soldered it out and measure that it was spoiled.
Ordered new one for 3 euro. Soldered new one on the board and the problem was solved.
Original was BTA16-700CW but they didnt have it so i replaced it with BTA16-600CW, difference is that original one can handle 700volt the new one 600, but there is only 220volt it will controll anyway so that was ok.
I atach a picture.

There is nothing you can do at this point, you will have to get your Saeco Primea Ring Serviced.
