You could jot down and publish all your settings to see if any are obviously wrong.
They will be close to but not identical to these for the synchronika i would imagine. See bottom. I do not have the exact settings for the go.
To enter the advanced PID settings mode on the PID :
Turn your machine off
Hold down BOTH the left and right button on the PID at the same time
While both PID buttons are pressed down, turn the machine on and wait for “F.01” to appear
From here, you are in advanced PID settings mode. You can change your machine to function in Celsius or Fahrenheit, switch between 15 and 20 amp power modes (on applicable machines), change boiler temperature offset, and adjust boiler temperature.
To change a setting, press the left button on the PID until the setting you wish to change is showing. Press the right button on the PID to view that setting’s current value, and while the current value is shown press the right and left buttons to adjust it up and down. To exit advanced PID settings mode and save your settings, simply turn the machine off and back on again.
Its not recommend, changing of the P, I, D, or b settings on any of the machines. Changing those 4 settings will change the way the machines reheat and maintain temperature.
The settings that we recommend changing if you are looking for something a little different are:
The setting for which temperature scale you would like to use, commonly shown in the PID settings as F.01. - C (celsius), and F (Fahrenheit)
The setting to change your machine for running in 15 amp or 20 amp mode (on applicable machines). This setting is commonly shown as F.02
The setting to change the temperature of the coffee boiler, commonly shown in the PID settings as T1.
The setting to change the temperature of the steam boiler, commonly shown in the PID settings as T2.
NOTE: We do not recommend changing P, I, D or b settings. These change the algorithms for reheating and maintaining boiler temperature.
