What to do if my Vaillant ecoTEC plus 615 shows water shortage and a quick temperature rise?
If your Vaillant Boiler indicates a water shortage and a quick temperature rise, the pump might be blocked, the pump output might be insufficient, there might be air in the appliance, or the water pressure might be too low. Check and unblock or replace the pump and ensure adequate water pressure.
What causes fan speed variation in my Vaillant ecoTEC plus 615 Boiler?
Fan speed variation in your Vaillant Boiler can be caused by a blocked fan, a plug not inserted correctly on the fan, a defective hall sensor, a fault in the cable harness, or defective electronics. Check the fan for blockages and connections, and inspect the sensors.
What does it mean if my Vaillant ecoTEC plus 615 shows eBUS undervoltage?
