sorry what is the pcb guage? the boiler will fire and light but does not sound too good, the pilot light won't stay on. how would we tell if the water guage is blocked? thanks a lot

Is this actually a 400 series fitted to a sealed system, or is it actually a 624 system boiler or an 824 combi? A 424 doen't actually exist! sorry vaillant turbomax 242e combi boiler we have had a plummer to look at this and he says it needs a new circuit board and a new water meter guage...

we have a vailllant 424 with no water pressure. when we try to add water its goes out of the overflow pipe, is ther another way to add water to the boiler thanks jean
