Ferroli maxima 35c F1 fault in cold weather?

My condenser boiler stopped working today and showed up fault F1. Gas supply fine as gas cooker working.

After a long look I found it was the condensate outlet had frozen up. I cleared the ice from the pipe and now heating working again.

The other possible faults are gas valve and full auto faulty but they were all fine. Hope this helps
