my vaillan ecotech boiler pressure is at the max on the red side?
I have a vaillant ecotech boiler. The pressure was down so I tried to raise it but forgot to switch the pressure off. It was on all night. It's now leaking and shows on the screen where you normally see the temperature 23c and 2.3 bar. Is this a serious fault and was has gone wrong?
thats ok ,first why did it drop they must be leak in system,repair that first,normal working pressure is 1.2bar can go up to 2.5 boiler will work fine,you can bring it down by taking water from radiator air vent
