vaillant boiler pressure too high

Vaillant Ecotec Screwfix Community Forum

2012-6-28 · When heating is on the pressure will rise as there is no charge to push on the expanding water. If it reaches around 3 bar, pressure relief will open and dump or drip away your pressure. When the boiler cools again the pressure will drop down again as the water contracts and shows the real pressure as some of the water is lost.

What Pressure Should My Boiler Be? Making Sure …

2019-8-28 · What if my boiler pressure is too high? If the boiler pressure is above 2 bar or the needle is in the red zone, you'll need to release some of that pressure. The best and easiest way to do this is to bleed 1 or a few of the radiators in your home. Turn off your heating system. Place a radiator key or flathead screwdriver into the top valve.

Vaillant Boiler F20 Fault Code Over Heating - …

2019-1-3 · A boiler's computer will display what it thinks is the most relevant fault code for the issue. If a PRV has been removed or blocked to stop a leak (which is not the correct fix anyway), there's a chance the increased pressure could cause a F20 fault code to appear. Some Vaillant boilers don't have a "pressure too high" related fault code.

How do I reduce water pressure on Vaillant Ecotec 831

2009-12-14 · Best Answer: If your boiler pressure is 3.4 when it is hot, thats okay. If this is the pressure when it is cold, then you can open a bleed vale to let water out until it shows between 1 and one and a half bar. Water expands as it is heated, that is why you get a higher reading when the boiler is hot.
