Trouble Shooting
HEATER WILL NOT SWITCH FROM STANDBY TO ON (RED LIGHT)
In most cases this will be the result of one of the following points not
being met.
Possible cause 1
: The temperature point set has been achieved. To confirm
the increase of the temperature set, turn the dial to a value greater than the
current water temperature.
Fig 15.
Possible cause 2 :
NO FLOW message
This message is displayed (see Fig.15) only when the heater is not receiving
enough flow. This could be due to the circulation pump being switched off.
The pump is not powerful enough to meet flow requirements (page 8). The
cartridge filter needs cleaning or replacing. The sand/glass media filter
creates too high a backpressure and needs backwash.
Possible cause 3 : HEATER DELAY message
Please refer to page 12
