I have a Protherm 80E combination boiler it is roughly 3 years old. over the last week, daily the display shows code F1 and i have to keep reseting my boiler daily. The bar pressure varies from 1.9 to 2.2 is the pressure too high? The manual states that F1 occurs after a safety lock out. What does this mean?
Is this a major problem? can it be fixed easily? Obviously this shouldnt happen daily so any advice would be grateful.
hi i have the same problem but only happens when the heating is on. its quite annoying as it can happen when in the bath or shower and the water turns cold.
would appreciate an answer if anyone knows
thanks

Hi,
your boiler pressure is fine between 1.9 - 2.2 bars and this would not be the reason your boiler is locking out.
is there anything specific happening before the lockout occurs, for example does it happen whilst the heating is on or if there is a demand for hot water?
do you have a manual for the protherm 80E?
