potentially damage the Heat Exchanger.
[How to reset error code 64]
Before resetting the error code 64, purge air
from the internal pump in the Combi Boiler
completely according with pages 68 - 69. Failure
to properly remove air from the internal pump
will cause this error to continuously appear and
potentially damage the Heat Exchanger. To reset
the error code 64, turn off the Maintenance
