Thanks for the reply Hugh. I'll check that.
Anyone know why the system should play up after being off for two weeks, and why I get the buzzing from the boiler on start up ? I did read that a faulty MPV can cause a Baxi Solo to buzz ?
Many thanks.
Hi, I'm new to this group and I hope there are some experts out there who can help.
Boiler - Baxi Solo 2 40PF
Drayton Mid position 3 port valve
Problem. House left empty for 2 weeks boiler - OFF
On start up - Buzzing sound from boiler.
Boiler starts and we have hot water but No heat...
