what does this mean when displayed on my vaillant ecotec 630 display. My boiler is showing that it is running at 2.5psi and then it cuts out. unless i bleed one of the radiators to lower the pressure it wont ignite, after lowering pressure by doing this it does but for how long is anyones guess. so the long and short of it is i am very confused and a bit pissed off
