by what means is it overfilling?

has it been properly skimmed/flushed etc. if the water is priming due to contaminants and it is activating the LWCO/auto-feed prematurely/unnecessariliy that would cause an overfill.



what type of LWCO installed?

what type of auto-feed?



pictures would be helpful.

the wet returns

could well be blocked. if the water can;t get back to the boiler fast enough then the auto feeder will feed (presuming you have one). when the water does get back the boiler will be flooded

yeah those are really ...

your only two options ...



in-boiler water level violent and dropping due to contaminants ..

or slow returns ..

both *may* be solved by adjusting the timing between when LW is sensed and auto-feed is activated ..



but in the case of contaminants, a thoroughly cleaning and skimming is really the PROPER means of a correction ..



slow returns may just require that the boiler start a bit overfilled to allow a buffer to catch up .. however, be wary of stacked A Dimension so that you don't stack into your mains due to slow returns



even a leak wouldn't show as an overfill.



curious .. why was the new boiler installed? something happen to the old one?
