I have a Vokera Linea 28 which has been on the 'hot water' setting all summer and worked fine.
Now it has got colder I have switched it to 'combined heat and water' and the pump does not kick in, despite me switching the time clock to "constant" and turning the stat up to full.
I've has a quick look ( having switched off the power) and both pcb fuses are fine and all connections are good.
I have to confess it has not been serviced since new 5 years ago.
Is there anything obvious that I may have missed, save getting it serviced?
Could it be the pump or maybe the clock not switching on?
Grateful for any advice please?
Thanks
K
