8 Troubleshooting
8.1 Introduction
This chapter covers the following errors:
•
Gas smell .
• Water leakage .
• Explosive ignition .
• Poor flame profile .
• No hot water
• Insufficient hot water .
If the water heater should go into an "error" state, you will be unable to draw hot
water. These error conditions are divided into three groups:
•
Lockout error due to flue gas thermostat
The lockout (push button) of the flue gas thermostat in the draught diverter
has been activated. See paragraph
5.7 Flue gas thermostat reset button .
After removing the cause, the push button must be pressed to re-start the
water heater.
• Lockout errors of the burner control
In this event, the red error LED on the control panel will be illuminated. The
burner control is locked out.
After eliminating the cause. the water heater must be returned to service by
pressing the reset button (see
5.6 Burner control reset button ).
• Blocking errors
You can recognise this status by the fact that the water heater will not start
operation, despite the water temperature being lower than you have set with
the control thermostat (see
5.5 Control thermostat ).
These errors disappear automatically once the cause of the error has been
removed, after which the water heater re-starts itself.
The following pages provide troubleshooting tables for each type of error.
