hi chaps, got a fault with my worcester 350 boiler. hot water works fine and heating switches on straight away, but after i have switched the heating off the pressure seems to drop and only when the system is recharged will it switch on as low pressure light illuminated.
 
could it be as simple as the pressure relief valve?? will check it out in the morning. thankyou.
 
mine was also a question, i will check it out in the morning and go from there thanks for you help.
