    What to do if my DeDietrich Innovens MCA 35 Boiler shows a B02 - BL.HEATING SPEED error?

      Julia EdwardsAug 5, 2025
      If your DeDietrich Boiler displays a B02 - BL.HEATING SPEED error, several issues could be the cause. It may be due to insufficient water flow in the installation, so you should check the circulation, pump, and valves. Also, make sure to check the water pressure and the cleanliness of the heat exchanger. Another potential cause is a sensor error, so verify that the sensors are operating correctly and that the boiler sensor has been correctly fitted.
