On systems using Vitotronic 200 controls, D6 specifically points to a flow switch issue, indicating that the minimum required flow rate has not been reached.
In some configurations, it may indicate a fault at the DE1 connection on the external safety device adapter. Common Causes of a D6 Fault Several underlying issues can trigger this lockout:
The is a specific fault code that indicates a critical communication or hardware failure, most commonly related to the fan speed or a flow switch malfunction , depending on your specific model . When this code appears, the burner typically switches to a lockout state to prevent unsafe operation or damage to internal components. What Does the D6 Error Mean?
Loose or corroded cables between the fan and the main control board (PCB) can disrupt signals.
