Gents, just found this forum on the internet and it looks very helpful! I bled my heating system last night (Powered by a Baxi Combi 105e) not releasing the error in reducing the system pressure. This was down to zero, since repressurised by opening the valve under the system, but I can't get the low pressure warning light to reset. I've seen various references to the solution being on the FAQ's on here but I can't see the FAQ's. Please can anybody help? Thanks
