Error codes for wall-mounted gas boilers De Dietrich

To restart the unit, set the mode switch for two seconds to the Reset position. If this device works again, contact a specialist. The ability to make only five attempts to restart the unit, after that it is blocked. To take a new attempt to restart the boiler, it is required to turn it off for a few seconds.
