Hi, I have a Lifestyle lp241 programmer, drayton ma1 actuator.
Recently, when both hot water and heating programmes come on, neither work, although programme lights come on.
When you manually turn either of the systems off at the control box the other one works!!
Have had the actuator changed but fault still persists. Any ideas please?
Did it work fine before ? couldn't be a wiring fault ?
You need a RGI or at least someone that can use a multimeter and see what's happening when you call for heat, you say the demand lights come on but where does the power go ? Some systems are all wired via the boiler, so could be fault with PCB.
