What does Fault code 30 mean on a Viessmann B1HA?
If your Viessmann Boiler displays Fault code 30, this indicates a short circuit in the boiler water temperature sensor. You should check the boiler water temperature sensor.
What to do if my Viessmann B1HA Boiler starts a self-diagnostic check when turned on?
When the Viessmann Boiler is initially turned on, it starts a self-diagnostic check. Wait until the temperature display stabilizes and the boiler displays the actual temperature.
What to do if my Viessmann Boiler shows fault F4?
If your Viessmann Boiler displays fault code F4, there are several potential solutions: * Check the ignition module connection. * Check the gas train (control voltage 230 V) and the gas supply pressure. * Check the ionisation current, the electrode adjustment, and the gas line for air-locks.
What to do if Viessmann B1HA burner shuts down below set temperature?
If your Viessmann Boiler burner shuts down below the set boiler water temperature and restarts immediately, check the flue system for tightness to prevent flue gas recirculation. Also, inspect the condensate drain and verify the gas flow pressure.
What to do if Viessmann B1HA displays fault F4?
If your Viessmann Boiler is showing fault F4, check the ionisation current, the electrode adjustment, the condensate drain, and the gas line for airlocks.
What to do if the fan in my Viessmann B1HA starts no after approx. 51 s?
If the fan in your Viessmann Boiler does not start after approximately 51 seconds, check the following: 1. The fan itself. 2. The fan connecting cables. 3. Power at the fan. 4. Fan control.
What to do if Viessmann B1HA shows fault F4 (Check gas train)?
If your Viessmann Boiler displays fault F4 related to the gas train, you should check the gas train, ensuring the control voltage is at 230V. Also, verify the gas supply pressure.
What to do if Viessmann B1HA Boiler shows fault F4 (Measure ionisation current)?
If you're seeing fault F4 on your Viessmann Boiler related to measuring ionization current, you should measure the ionization current. Also, check the electrode adjustment and inspect the gas line for any airlocks.
What does fault code 38 mean on Viessmann B1HA Boiler?
If your Viessmann Boiler displays fault code 38, which indicates a lead break in the boiler water temperature sensor, check the boiler water temperature sensor.
What does fault code 10 mean on my Viessmann Boiler?
If your Viessmann Boiler displays fault code 10, it indicates a short circuit in the outside temperature sensor. Check the outside temperature sensor and lead.
