Hi colebatchd Fantastic to read you're back up and running Indeed there appears to have been a minor fault record on your two NTC temperature sensors in both your Brew Boiler (Error code 10) and your Grouphead (Error code 12). It looks like you had a few (minor number of) over-temps on your Brew boiler that radiated/spilled over-temps three times to your Group head's NTC temperature monitor system.
