A year ago we had a new Vaillant ecoTEC plus 637 system boiler installed.
This morning I was awoken at around 6:00am (the time the thermostat increases the temperature to start to warm the house up) by a loud gurgling sound coming from the boiler in the garage under our bedroom.
I imagined water leaking all over the garage floor! What I found was the analogue pressure gauge was reading zero, but the boiler was still trying to pump water (or whatever it does). I allowed more water into the system, which increased the pressure and the gurgling noise disappeared - everything was back to normal. I noticed that there was some water on the floor underneath the boiler but I wasn't sure where it was coming from. It may have been from the filter next to the boiler, rather than the boiler itself.
It was my understanding that the boiler was supposed to report a low water pressure event and that it certainly shouldn't have continued to attempt to work, producing a noise that sounded like it was doing some internal damage
Does this suggest there may be a problem with the boiler?
