Good morning, my name is ***** ***** I will assist with your query today.
If hot water is working this suggests the boiler is at the right pressure and the ignition system is all working, the digital display I assume you refer to, is this the one located next to the pressure gauge and normally displays the time?
Should the digital display not show anything (totally dead) this will be the reason why CH has failed, as the timer only affects the CH not the HW.
A new timer is around £60 in parts, if you provide me with your postcode I can recommend a Gas engineer in your area to come and replace it for you.
Good morning, I havent heard from you in a while, do you still require assistance?
Good evening, I havent heard from you in a while, do you still require assistance?
