Baxi Primary Flow Filter 7216596

The Baxi 7216596 is a primary flow filter supplied by Baxi for the Main Eco Combi range of gas boilers. It sits in the primary water circuit and traps circulating debris before it can reach the heat exchanger and other hydraulic components. Keeping the primary side clean protects flow rates and helps the boiler maintain stable heating and hot water performance.

• Reduced heating output or uneven radiator temperatures across the system
• Boiler cycling or locking out when demand is high
• Sludge or magnetite visible on the filter element during a service
• Restricted primary flow causing the boiler to run hotter than expected
• Noisy operation from the pump or heat exchanger area

• Check the GC number on the appliance data badge against the compatibility list to confirm the correct fitment.
• Cross-reference the alternative number 1132081 if you are working from an older parts listing.
• Inspect the filter housing and seals while the part is out, and replace any worn seals before reassembly.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
