hi
sounds like the thermo coupler is faulty. 99.9% sure this is the probem.
easy fix all ou need is new thermo coupler buy a universal one cost around £15. look in boiler you will see a thin copper wire on both ends there is a nut. undo the nuts pull out and re-fit new one. simple as that. any problems or q mail me on taz2023@talk21.com
