Hi - Can anyone offer advice - We have a Riello Oil Burner RDB2.2. The complete unit was replaced at the beginning of the year and we have had problems since. The motor is seizing and causing the fan etc to jam. If you turn the fan until there is no resistance, then it will restart. It only runs for 30mins to a couple of hours and then the same thing happens again. It runs on Diesel and has the lubricant additive in the tank and the pressure is set to 12Bar. Has anyone had similar problems. Our previous pump ran for many years without problem until it needed replacing but we don't know why this new one won't run properly. Thanks for any help offered.
