Can any one help me please I have a Ravenheat RSF 84ET that when the timer clock is in the off position the boiler still fires up whether it is switched to either water only or heating and water,it also makes a wooshing noise like a kettle with no water and after a minute the bar guage shoots up to maximum and then the boiler locksout.
when it has cooled down it will let me reset and then it does the same as above.
