Actually, based on what the boiler engineer showed me, I clearly didn't know how to pressurize the system and neither did my landlord. When I initially posted, I was hoping someone with Vaillant boiler experience would respond. The F.22 would have given the problem away immediately. No...

Some things are so simple to fix. Underneath the boiler there are two gray knobs. They are used to fill the small tank in the boiler and increase the pressure. I didn't even know they existed as the tank is mounted low enough to where you have to bend down to see underneath it. All the...

I do believe the boiler is only a few months old. I believe it was installed in January. The boiler engineer will be out tomorrow. I'll post the results here when the boiler is repaired.

It's a two story detached home.

I was just following my landlords instructions for when the pressure drops. I shouldn't of ever had to do it because it's clearly a problem if the water pressure is fluctuating low enough to shut the boiler down over and over. He didn't think it was a problem, but I'm not sure he ever read the...

This is a very recent boiler. It is possible with a little ingenuity to increase the system pressure to the correct value of about 1.5 Bar. The F22 error may be caused by other factors than the low pressure but that should be sorted out first before coming to any diagnosis. Your...

The home I am currently renting has a ecoTEC plus 837 that doesn't seem to get adequate pressure to work for very long. I am constantly having to reset the system due to error F.22 and even then the pressure never goes above 0.6. My landlord insists this is normal, but the Vaillant book he...
