Hi. My father in law has a Worcester Bosch 12/14 Oilslave system. He went to the oiltank the other day and the valve was half turned off - he suspects that someone thought it was a tap and had been tampering with the tank. Although he turned the valve fully on again, he has had intermittent problems with the boiler cutting out since then, and he has to press a reset button in order to clear a 'Lock Out' warning. He's bled the system a couple of times and last night it ran all evening withoout a problem - is the intermittent problem likely to be solved by further bleeding of the system?
Thanks.
Thanks.
