LED OPERATION
Refer to
on page 9 for further information on the types of flashes the LEDs produce.
All LEDs are Off (no illumination)
If all LEDs remain off, check there is a power supply
to the water heater.
Refer to
“Is the electricity switched on?”
on page 19.
If there is power available, there may be a problem
with the water heater. Phone your nearest Solahart
Dealer to arrange for an inspection.
All LEDS are Solid (constant illumination)
If all LEDS remain on with a solid illumination, there is
a problem with the water heater.
Phone your nearest Solahart Dealer to arrange for an
inspection.
Yellow LED is Solid (red LED is off)
If the yellow LED is solid, this is a warning there may be a fault with the water heater. The fault may be
cleared by resetting the water heater.
Reset the water heater. Refer to
on page 20.
Red and Yellow LEDS are Standard Flashing Together
If the red and yellow LEDs are flashing together, with a three (3) second pause between the sequences
of flashes, there may be a fault with the water heater.
Reset the water heater. Refer to
on page 20.
Red LED is Fast Flashing (yellow and green LEDs are off)
If the red LED is fast flashing, there may be a fault with the tank Master Controller Module.
Phone your nearest Solahart Dealer to arrange for an inspection.
Blue LED is Blink Flashing
The blue LED blink flashing indicates the external control device has not communicated with the water
heater for more than thirty (30) minutes. Communication may re-initiate after this time, or if not this may
indicate a fault with the external control device or the water heater.
Check the operational
status of the external control device. Refer to the Owner’s Guide / Instructions
supplied with the device. If the external control device is not operating as described in its literature, phone
the Service Provider to arrange an inspection.
If the operational status of the external control device is as described, reset the water heater. Refer to
on page 20.
RESET THE WATER HEATER
To reset the water heater:
Press and hold the Push Button for between three (3) and six (6) seconds, then release.
During this time, the green LED will be solid for three (3) seconds, then go off. Release the Push Button
whilst the green LED is off.
The water heater will enter an ‘Initialisation mode’ and the green, yellow and red LEDs will flash in an undefined
sequence for up to sixty (60) seconds, which will include different types of flashes and may include short
periods where the LEDs are remain all on or all off. This is normal operation. Check the blue LED is extra fast
flashing, indicating it is communicating with the external control device.
When the Initialisation mode is complete, and if a potential fault is cleared, the green LED will either be solid
(Standby mode) or standard flash to indicate the current operational status of the water heater. The blue LED
will continue to extra fast flash.
