i have a Worcester 9.24 electronic combi boiler. the overheating
cut-out keeps cutting out and i have to keep resetting it. not had any
watermain work being done anywhere near or any other cause for loss of
water pressure. any ideas what it could be. do i need an overpaid
expert to suck his teeth and ask me who's had a go at this.it's cut out
about 4 times in the last week.
