If your central heating pressure is below 0.8, you'll need to top up your Luthmore central heating system. The Luthmore App may also show a 203 fault code.
It's easy to resolve. We've created a simple guide to help you do this.
Step by Step Guide:
1. Go to App > Setup > Boiler Settings to see the current Central Heating pressure
NB: If CH pressure is below 0.8 bar you will need to top up the system
2. Locate the metal ‘Valve Tool’ (or a T30 Torx screwdriver) and Valve Ports underneath the product and marked with 1, 2, 3 and 4 labels
3. Insert the ‘Valve Tool’ into Port 3 and turn anticlockwise for 3 full revolutions
4. Insert the ‘Valve Tool’ into Port 1 and turn anticlockwise for 3 full revolutions

The central heating system will start to fill with water, and you will see the pressure begin to rise on the App.
5. Fill the system until the pressure is between 1.2 – 1.5bar

6. When at the target pressure, turn the ‘Valve Tool’ in Port 1 clockwise until finger tight
7. Insert the ‘Valve Tool’ in Port 3 clockwise until finger tight
Once topped up, re run the central heating to check it's working as expected. This should also clear the fault code from the App. If the fault persists, repeat the above process and test again.
