Hello, i'm having problems with my Worcester 24i combi. It's approx 6yrs old and the water drops (dumps) from 1.5 bar down to almost zero resulting in me having to refill every time i require heating is the a quick fix solution and what spare parts if any are required? many thanks for reading this.

i'd say you have a leak of some sort! is the prv drain-off (which is the small pipe on the exterior of the building) dripping? if so, then the prv is faulty. needs a new one.
if not you have a system leak. that could be on the boiler itself ( any drips underneath?) or anywhere on the wet side. pipework, rads, rad valves. you'll need to start isolating parts of the system to find the cause. happy hunting!
