I needs some help please. My Grant Vortex 26e boiler has developed a fault.
Both CH & HW pump led’s are flashing continuously - I’ve tried switching it off & putting it back on, but it won’t reset.
I found a fault with the CH pump, so I’ve replaced it. Last year it had a new expansion tank & HW pump.
There are no obvious faults.
I’ve unplugged everything except from the PCB except for the Mains plug & the fault remains.
Got a bad feeling it’s the PCB.
Any advice would be brilliant. Thanks
