What does it mean if my Vaillant ecoTEC plus has gas valve shutoff delay defective?
If the gas valve shutoff delay is defective in your Vaillant Boiler, it could be due to a leaking gas fitting or defective electronics. Inspect the gas fittings and replace faulty electronics.
Why is my Vaillant Boiler showing 'Electronics temperature too high'?
If your Vaillant Boiler displays 'Electronics temperature too high', it means the electronics are too hot due to an external effect or the electronics are defective. Ensure proper ventilation for the electronics and replace them if they are defective.
How to fix a flue gas safety temperature limiter issue in Vaillant Boiler?
If the flue gas safety temperature limiter is addressed in your Vaillant Boiler, it indicates that the flue gas temperature is too high. Check the flue gas system and ensure it operates within temperature limits.
What should I do if my Vaillant ecoTEC plus Boiler shows water shortage due to a quick temperature rise?
If your Vaillant Boiler displays a water shortage due to a quick temperature rise, it could be caused by a blocked pump, insufficient pump output, air in the appliance, plant pressure being too low, or the flow and return NTCs being interchanged. Check for pump issues, air in the appliance, and ensure proper pressure.
What should I do if my Vaillant ecoTEC plus shows water shortage due to a large temperature spread?
If your Vaillant Boiler indicates a water shortage due to a large temperature spread between the flow and return probe, the pump might be blocked or defective, or the pump output might be too low. Check the pump for blockages or defects.
What does it mean when my Vaillant Boiler displays an EEPROM error?
An EEPROM error on your Vaillant Boiler indicates that the electronics are defective. Replace the defective electronics.
What causes a safety temperature limiter to be addressed in a Vaillant ecoTEC plus?
If the safety temperature limiter is addressed in your Vaillant Boiler, it could be because the flow probe is not correctly thermally connected or is defective, or because the appliance does not shut down. Ensure proper thermal connection of the flow probe and replace it if it is defective.
Why is my Vaillant ecoTEC plus Boiler showing a dry fire error?
A dry fire error in your Vaillant Boiler can occur if there is too little water in the appliance, the water shortage switch is defective, the cable to the pump or water shortage switch is defective, the pump is blocked or defective, or the pump output is too low. Refill the water and check the water shortage switch and pump.
What to do if the flame goes off during operation of my Vaillant Boiler?
If the flame goes off during operation and subsequent ignition attempts fail in your Vaillant Boiler, it might be due to a temporarily stopped gas supply, a spark failure in the ignition transformer, or faulty earthing of the appliance. Check the gas supply and ignition transformer to resolve this issue.
What to do if my Vaillant ecoTEC plus Boiler appliance does not start and ignition fails?
If your Vaillant Boiler fails to start and the ignition attempts are unsuccessful, it could be due to faults in the gas supply such as a defective gas meter or gas pressure detector, air in the gas, gas flow pressure being too low, or the fire protection tap has disengaged. It may also be due to faults in the gas fitting (main gas magnet or operator defective), wrong gas setting, a defective igniter (ignition transformer, ignition cable, ignition plug), stopped ionization current (cable, electrode), faulty earthing in the appliance, or defective electronics. Check the gas supply and fittings for faults, and replace any defective parts.
