Before you order
- Confirm the part number AA078331 matches the item required for the boiler being worked on.
- Check the appliance model and any installer or service documentation before ordering, as pressostat fitment varies between boiler ranges.
- Inspect the existing pressostat, its sensing pipework and electrical connections so that any associated faults are identified before the new part is fitted.
