The boiler starts but does not produce heat: pressure, circulation, and draft may be behind the fault.
Smoke in the air, poorly closed doors, and irregular combustion: this is how this fault is diagnosed and corrected.
The fault indicates the sensor of accumulator 2 and affects the hot water. This is how it is interpreted and why it usually requires a technician.
The fault usually points to the internal electronics and requires specialized technical inspection to avoid further damage.
The warning usually indicates an internal link fault or a power supply issue. This is what it means and how to address it.
Lack of flow in a Dietrich boiler usually points to air, pump, low pressure, or closed valves.
The boiler sparks but does not ignite: causes, checks, and useful signs to diagnose the fault.
The boiler turns on, but the ionization signal does not reach the minimum level. This is how it is interpreted and acted on safely.
A reversed circuit can stop the boiler. These are the key checks to locate the fault systematically.
This warning indicates a detection, connection, or configuration problem with the SCU card and usually requires technical review.
The fault usually points to overheating: sensor, circulation, air, and pressure account for most cases.
The boiler may lock out due to an internal anomaly in the ABM03 control unit. These are the causes and the actual scope of the fault.
