Display showing “Water deficiency: follow the instructions in the heat gen.” No error code showing. Water pressure is 0.8, which is within acceptable range. I’m not sure what the heat gen is, or where to look for mentioned instructions. Can you please advise?

The "Water deficiency: follow the instructions in the heat gen" message on a Saunier Duval Mono FW 200-6 indicates that there is insufficient water in the heating system. This can cause the system to stop working correctly.

To resolve this, you should check the system pressure and refill the heating circuit if needed. The instructions for checking and correcting this are found in the troubleshooting section of the operating instructions. If the issue continues, contact a competent person.

Hello I have heating but I don’t have hot water. Saunier duvel géniaset fw200-6

If there is heating but no hot water in the Saunier Duval GeniaSet Mono FW 200-6, possible reasons could include:

1. Hot Water Temperature Setting – The domestic hot water temperature may be set too low or turned off.
2. Fault Messages – The system may display an error indicating an issue with hot water generation.
3. System Pressure – If the system pressure is too low, it may affect hot water production.
4. Magnesium Anode or Heat Exchanger Issues – Corrosion protection failure or a blocked heat exchanger could prevent proper heating of water.
5. Expansion Relief Valve or Safety Devices – If the expansion relief valve is faulty, it may prevent hot water from reaching the required temperature.
6. Back-up Heater Issues – If the back-up heater is not functioning correctly, water may not be heated properly.
7. Heat Pump Functionality – If the heat pump is not working correctly for hot water but still functions for heating, the issue may be specific to the domestic hot water system.

Checking the settings, reading fault messages, and ensuring proper maintenance can help identify and resolve the issue.
