Troubleshooting

In the unlikely event that a problem occurs with the ope-
ration of the turboMAX plus or thermoCOMPACT boiler,
the following points should be checked:
1. Boiler fails to operate:
• Is the gas supply turned on? (see page 5)
• Is the water supply turned on? (see page 5)
• Is there enough water in the heating system? (see
page 5)
• Is the electrical supply switched on?
• Is the main ON/OFF control in the „On" position?
(switch position „I") (see page 5)
• Is the burner lock out indicator light illuminated? (see
page 6)
2. Hot water operates but no central heating
(turboMAX plus only)
• Is the heating turned on? (see page 7/8).
• Are all external heating controls ON? (see page 8)
If your boiler still does not operate then please consult
your installer or Vaillant Service Solutions
0870 6060 777.
