If your Dunkirk Boiler has a gas valve command fault, verify all cables and replace the PCB.
What to do if Dunkirk Boiler has gas valve command fault?
If your Dunkirk Boiler has a gas valve command fault, verify all cables and replace the PCB.
What to do if safety thermostat tripped in Dunkirk Boiler?
If the safety thermostat has tripped on your Dunkirk Boiler due to over temperature, which may be caused by a blocked pump or air in the heating circuit, check the safety thermostat and its cable. Also, verify the correct circulation of water and the pump.
How to fix combustion test alarm during calibration of Dunkirk DCB-165?
If your Dunkirk Boiler's combustion test triggers an alarm during commissioning or calibration, examine the flame sensor. Check for any obstructions in the flue pipe and look for recirculation issues. Verify the gas pressure, gas orifice, and gas quality. You may need to perform automatic and manual calibration functions.
What to do if hydraulic pressure is too high in Dunkirk DCB-165?
If the hydraulic pressure in your Dunkirk Boiler is too high, relieve the pressure using the relief valve or by draining the system. Ensure that the water feed is operating correctly.
How to fix low hydraulic pressure in Dunkirk Boiler?
If the hydraulic pressure in your Dunkirk Boiler is too low, refill the heating system by opening the cold water tap.
