Gas control electronic fault detected (ICON System V1)
LED: 7 flashes, 3-second pause
On the ICON System V1 control, seven flashes with a three-second pause mean "Gas control electronic fault detected". The manual's probable causes are that the control needs to be reset or that it is wet or physically damaged, and its service procedure is to reset the control first and replace it if the fault returns.
Applies to
Applies only to tanks fitted with the ICON System V1 gas control. The V2 control chart does not document a seven-flash pattern, so a seven-flash reading identifies the control as V1.

Why a code is not a diagnosis
The code is the control's own fault report, and the manual's first step is a reset: a control that has been damp, disturbed or faulted once may clear and run normally. A pattern that returns after the reset points at a wet or damaged control that must be replaced.
Safe things to observe
- Note the flash count and whether the pattern clears after the manual's reset.
- Check the area around the control for moisture or recent flooding before anything else.
Do not
- Do not reset the control repeatedly to restore hot water.
- Do not dry a wet control with heat or compressed air or open the control body.
- Do not bypass the control to force the burner on.
How professional service helps
- A technician resets the control by the manual's procedure, inspects it for moisture or damage, and replaces the gas control if the fault returns.
