Frequently Asked Questions - MBS-B 200 DE DIETRICH
How do I reset the boiler after a fault?
Press and hold the reset button for 3 seconds. If the fault persists, check the error code on the display and consult the manual or contact a technician.
What is the recommended water pressure for the system?
The recommended water pressure is between 1.0 and 1.5 bar when cold. If it drops below 0.5 bar, refill using the filling loop.
How often should I service the boiler?
An annual service by a qualified engineer is recommended to ensure efficient and safe operation.
Can I install the boiler myself?
No, installation must be carried out by a registered gas safe engineer or qualified heating installer according to local regulations.
What does error code E01 mean?
Error code E01 typically indicates a fault with the flame detection. Check the gas supply and ensure the burner is clean. If it persists, call a service engineer.
How do I adjust the hot water temperature?
Use the temperature control dial on the front panel. Turning clockwise increases temperature. Allow a few seconds for adjustment to take effect.
Why is my radiator not heating up?
Check that the radiator valves are open and the system pressure is adequate. Bleed the radiator if there is trapped air. If still cold, there may be a balancing issue or a faulty valve.
Can I use the boiler if the pilot light is out?
If the boiler has a pilot light, it should be lit for correct operation. Follow the relighting instructions in the manual. If it repeatedly goes out, contact a technician.
What type of gas does this boiler use?
The boiler is compatible with natural gas (G20) or propane (G31), depending on the configuration. Check the data plate for the correct gas type.
