Hi there, I have a Vokera 20 80 RS Flowmatic that was serviced about 6 moths ago.
Sometimes the burner won't fire when I put a hot tap / shower on, but if I switch on the heating to 'constant' then switch it off immediately, the burner will fire up when I put hot tap / shower on.
Any ideas what the problem may be.
Thanks in advance.
