How to Repressurise Baxi Platinum Combi Boiler

Maintaining the correct pressure in your Baxi Platinum Combi boiler is crucial for its efficient and safe operation. This comprehensive guide will walk you through the step-by-step process of repressurising your Baxi Platinum Combi boiler, ensuring optimal performance and preventing potential issues.

Identifying the Filling Link

Easy-fill Filling Link

Locate the green lever on a brass fitting near the front on the right-hand side of your Baxi Platinum Combi boiler.
Firmly pull the green lever down with your finger. You should hear the sound of water flowing into the system.
Keep a close eye on the pressure gauge while holding down the lever.
Release the lever when the needle on the pressure gauge rises to the middle of the green triangle, which indicates a pressure range of 1 to 1.5 bar.

Rigid Filling Link

Identify the two blue taps located underneath your Baxi Platinum Combi boiler.
Ensure that both blue taps are in the off position, perpendicular to the pipes.
Remove the two brass caps attached to black rubber straps.
Fit the copper bend with rubber washers to each side of the filling loop and tighten the wing nuts securely.
Push the blue tap on the left-hand side away from you.
Slowly open the second blue tap on the right-hand side until you can hear the water start to flow.
Continuously monitor the pressure gauge and close the tap when the needle rises to the middle of the green triangle (1 to 1.5 bar).
Pull the right-hand lever towards you to close the tap.
Turn the tap on the left-hand side towards you to turn it off.

Additional Tips

Ensure that the pressure gauge needle is positioned in the middle of the green triangle, which corresponds to a pressure range of 1 to 1.5 bar.
Always turn off the boiler before attempting to repressurise it.
If you find yourself needing to top up the pressure frequently, it may indicate a larger issue with your Baxi Platinum Combi boiler. In such cases, it’s recommended to contact a heating engineer or Baxi Customer Support for further assistance.
