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 has gone into an error condition, then the heat demand will
be (temporarily) ignored and no hot water will be supplied. The frost protection
will also be out of operation. The error conditions are divided into three groups:
•
Lock out error in the burner control
When this happens, the red error lamp in the reset button will light up on the
control panel. The burner control is locked out.
After removing the cause, the reset button must be pressed to re-start the
water heater.
• The water heater cycles continuously
When this happens, the water heater continues to attempt to start-up, but an
error is causing the heating cycle to fail.
See paragraph
7.4 The water heater’s heating cycle .
After removing the cause, the water heater will start-up again by itself.
• Blocking errors
You can recognise this condition by the fact that the water heater makes no
attempt to 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 resumes by itself.
