i have a potterton performa 30he combi boiler,and it has a problem,it keeps coming up with a pump/water pressure warning,if the contact switch above the diverter valve is held up the boiler works as it should,the problem also affects the hot water as well,the plunger in the diverter valve does not seem to be working.i have had a new pump and diverter valve fitted and a new diaphram in the DHW as well,i cannot afford to keep spending on this boiler and i have no heating
