The Water Heater is equipped with an electronic diagnostic system which will detect fault conditions ranging from
poor gas or d.c. supply to internal Water Heater malfunctions. In the unlikely event of a failure, the red LED on the
Control Panel will light. To diagnose the problem please refer to the table on page 15.
Option 1 - Whale Space Heater Control Panel
In the unlikely event of a failure, the red LED on the Control Panel will flash a number of times, pause, and repeat
until switched off. Count the number of flashes and refer to the table on page 15.
Gas Lockouts
Gas lockouts
must be
cleared by moving the gas switch from ‘on’ position to ‘off’ position then back to the ‘on’
position. The complete sequence of switch movements
must be
completed within 2.5 seconds for a lockout to be
successfully cleared. If there is air in the gas line, e.g. after a gas bottle change, the Water Heater may require
several attempts before it lights.
Other Lockouts
If the lockout is caused when the unit is operated on electric, the lockout can be cleared by moving the electric switch
from ‘on’ position to ‘off’ position then back to the ‘on’ position. The complete sequence of switch movements
must
be
completed within 2.5 seconds for a lockout to be successfully cleared.
Note:
A cycling of the power supply to the unit will not clear a lockout. Some gas lockouts, e.g. Ignition lockout will
still permit use of the appliance in electric only operation.
If the problem persists contact
Whale® Support on +44 (0)845 217 2933.
Option 2 - Whale Duo Control Panel
In the unlikely event of a failure, the red ‘ ! ’LED on the Control Panel will light (see Fig. 30). To identify the lockout
press and hold, both the Water Heater Function Button and ‘ + ’. at the same time. The temperature control bars will
light to indicate the fault code e.g if 1 bar lights, the fault code is 1, if 2 bars lights, the fault code is 2 etc. Press ‘ + ’
to clear the fault code. Please refer to the table on page 14.
Note:
A cycling of the power supply to the unit will not clear a lockout. Some gas lockouts, e.g. ignition lockout and
combustion air faults will still permit use of the appliance in electric only operation.
If the problem persists, contact

Check gas supply making sure there is gas in the bottle and no blockage in the gas
line. Ensure propane is used at temperatures below +5°C. Clear lockout as described
above.
Check there is water in the appliance. Whale recommends you wait at least 5 to 10
minutes to allow the heater to cool before clearing lockout as described above
.
Minimum operating voltage is 10V, maximum is 15V, when measured at the Water
Heater. Check battery voltage. If between 10V and 15V, check connections between
Water Heater and battery. Check alternator or external battery charging. Clear
lockout as described above.
Attempt to clear lockout as described above. If this fails, contact a Whale Authorised
Service Engineer.
