Hello
Wondering if anyone here is a plumber or their dh/dp/anyone they could ask for me, please please!
Noticed the '40' light flashing on my boiler last night, a google for manuals for the boiler model says it means the DHW (domestic hot water) sensor is faulty or has a fault.
Does anyone know how urgent this is to be looked at/fixed?
Still have hot water, although it's a little bit cooler than it used to be it's still fine.
Is it an emergency?
Any idea what it would cost to fix?
Thank you in advance
