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 WB1A007 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 WB1A007 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 check if the gas train opens in a Viessmann Boiler?
If the gas train opens in your Viessmann Boiler, which is related to fault F4, you should check the gas train itself for the correct control voltage (230 V) and also verify the gas supply pressure.
What does Fault code 38 mean on a Viessmann WB1A007?
If your Viessmann Boiler displays Fault code 38, this indicates a break in the boiler water temperature sensor. You should check the boiler water temperature sensor.
What to do if the fan in my Viessmann WB1A007 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 WB1A007 Boiler 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 WB1A007 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.
How to solve control unit issues with no increase set value in Viessmann WB1A007 Boiler?
If the control unit of your Viessmann Boiler is not increasing the set value, increase the set value and ensure heat is being drawn off.
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.
