Hi i have a logic combi 30 and its broke down at least once a month for a year with same problems. It now been banging and gasping since 9:30pm (i filled it so I could get a shower wish I hadnt bothered and kept the flies as mates LMFTO) I have 5 kids and its woke them up (attic bedrooms and boilers in kitchen) no error codes as yet I have to fill it to 1 bar at least once a day and its started again.
