There is no hot water in the Viessmann VITOPEND 100-W due to one of the following reasons:

1. The heating system is switched off.
Remedy:
- Turn on the ON/OFF switch.
- Switch the mains isolator ON (if installed).
- Check the MCB/fuse in the power distribution board.

2. The control unit is incorrectly adjusted.
Remedy:
- Ensure DHW heating is enabled.
- Check and correct settings for:
- Operating program
- DHW temperature
- Time program for DHW heating

3. Message code 06 is flashing, indicating low pressure in the heating system.
Remedy:
- Top up with water or notify a heating contractor.

4. A fault code (F02, F03, F04, F05, F07, or F08) is flashing, and the on-symbol is shown.
Remedy:
- Simultaneously press the MODE and OK keys until the symbol flashes (reset).
- If the fault reappears, contact a heating contractor.
