If it turns out to be the ERC you may want to check out our website. We repair ERCs. We see a lot of intermittent F1 error cases (of course the meaning of F1 varies between models) but often they are caused by a component that fails in the safety circuit that controls the "DBL" (double break relay). We fully test the ERC and replace components that typically fail or are near end-of-life. We check the temperature calibration and we measure the contact resistance of the relays to help determine their condition.

It's not unusual for the F1 code to start randomly, then become more frequent over time and eventually become permanent.
