Question 1

Whale Space Heater's diagnostic LED is lit red, but no fault code is showing yet

Accepted Answer

Possible cause: The fault code has to be actively displayed - it doesn't appear on its own. Hold the Space Heater's Function Key down together with its Temperature Adjustment Key (+ button) - this displays the fault code as a number of lit bars on the Temperature Gauge (1 bar = fault code 1, 2 bars = fault code 2, and so on). Match that number against the fault codes below.

Question 2

Whale Space Heater's diagnostic LED lights red, 1 bar lit on the temperature gauge

Accepted Answer

Possible cause: No flame detected. Check the gas supply (bottle has gas, no blockage in the line); ensure propane is used below +5°C, then clear the lockout.

Question 3

Whale Space Heater's diagnostic LED lights red, 2 bars lit on the temperature gauge

Accepted Answer

Possible cause: Overheat. Confirm nothing is restricting the Space Heater's air ducts or vents, allow it roughly 5-10 minutes to cool, then clear the lockout.

Question 4

Whale Space Heater's diagnostic LED lights red, 3 bars lit on the temperature gauge

Accepted Answer

Possible cause: Low or high supply voltage (operating range is 10V-15V measured at the Space Heater). Check the battery voltage; if within range, check the connections between the Space Heater and the battery, and check the alternator or external charging, then clear the lockout.

Question 5

Whale Space Heater's diagnostic LED lights red, 4 bars lit on the temperature gauge

Accepted Answer

Possible cause: Combustion air fault. Check the combustion air inlet and exhaust flues for blockages, then clear the lockout.

Question 6

Whale Space Heater's diagnostic LED lights red, 5 bars lit on the temperature gauge

Accepted Answer

Possible cause: Other/internal fault. Try clearing the lockout. If it doesn't clear, contact Whale Support at +44 (0)845 217 2933.

Question 7

Whale Space Heater's diagnostic LED is solid red

Accepted Answer

Possible cause: Two faults have occurred at once, or five or more lockout-clearing attempts have failed. Clear the lockout using the Space Heater's own red Reset Button.

Question 8

Whale Water Heater's diagnostic LED is lit red, but no fault code is showing yet

Accepted Answer

Possible cause: The fault code has to be actively displayed - it doesn't appear on its own. Hold the Water Heater's Function Key down together with its Temperature Adjustment Key (+ button) - this displays the fault code as a number of lit bars on the Temperature Gauge (1 bar = fault code 1, 2 bars = fault code 2, and so on). Match that number against the fault codes below.

Question 9

Whale Water Heater's diagnostic LED lights red, 1 bar lit on the temperature gauge

Accepted Answer

Possible cause: No flame detected. Check the gas supply (bottle has gas, no blockage in the line); ensure propane is used below +5°C, then clear the lockout.

Question 10

Whale Water Heater's diagnostic LED lights red, 2 bars lit on the temperature gauge

Accepted Answer

Possible cause: Overheat. Confirm nothing is restricting the Water Heater's air ducts or vents, give it roughly 5-10 minutes to cool, then clear the lockout.

Question 11

Whale Water Heater's diagnostic LED lights red, 3 bars lit on the temperature gauge

Accepted Answer

Possible cause: Low or high supply voltage (operating range is 10V-15V measured at the Water Heater). Check the battery voltage; if within range, check the connections between the Water Heater and the battery, and check the alternator or external charging, then clear the lockout.

Question 12

Whale Water Heater's diagnostic LED lights red, 5 bars lit on the temperature gauge

Accepted Answer

Possible cause: Other/internal fault. Try clearing the lockout. If it doesn't clear, contact Whale Support at +44 (0)845 217 2933.

Question 13

Whale Water Heater's diagnostic LED is solid red

Accepted Answer

Possible cause: Two faults have occurred at once, or five or more lockout-clearing attempts have failed. Clear the lockout using the Water Heater's own red Reset Button.
