Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | Whale Underfloor Space Heater's diagnostic LED is lit, but no fault code is showing yet | The fault code has to be actively displayed - it doesn't appear on its own | Press and hold the Space Heater Function Button to display the fault code - the number of bars that light on the temperature bar is the code (1 bar = fault code 1, 2 bars = fault code 2, and so on). Match that number against the fault codes below. | DIY Safe |
N/A | Whale Underfloor Space Heater: 1 bar lit on the temperature bar (diagnostic LED lit) | 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. | DIY Safe |
N/A | Whale Underfloor Space Heater: 2 bars showing on the temperature display (diagnostic LED on) | 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. | DIY Safe |
N/A | Whale Underfloor Space Heater: 3 bars showing on the temperature display (diagnostic LED on) | Low or high supply voltage (operating range is 10V-15V DC measured at the Space Heater) | Check the battery's voltage, and if it's within range, inspect the wiring linking the Space Heater to the battery, then clear the lockout. | DIY Safe |
N/A | Whale Underfloor Space Heater: 4 bars showing on the temperature display (diagnostic LED on) | Combustion air fault | Make sure neither the combustion-air inlet nor the exhaust flue is blocked, then clear the lockout once they're clear. | DIY Safe |
N/A | Whale Underfloor Space Heater: 5 bars showing on the temperature display (diagnostic LED on) | Other/internal fault | Attempt to clear the lockout. If that fails, contact Whale Support on +44 (0)8452172933. | DIY Check / Tech Fallback |
N/A | Whale Underfloor Space Heater is locked out and won't clear by cycling the power | A lockout requires its own reset procedure - simply turning the power off and on does not clear it | Follow the heater's own reset procedure until the fault code disappears from the temperature display, allowing a few seconds for the diagnostic light to go out; a gas-related lockout (fault 1 or 5) still lets you run the heater on electric only. If the problem continues, contact Whale Support on +44 (0)8452172933. | DIY Check / Tech Fallback |
N/A | Whale Water Heater's diagnostic LED is lit, but no fault code is showing yet | The fault code has to be actively displayed - it doesn't appear on its own | Press and hold the Water Heater Function Button to display the fault code - the number of bars that light on the temperature bar is the code (1 bar = fault code 1, 2 bars = fault code 2, and so on). Match that number against the fault codes below. | DIY Safe |
N/A | Whale Water Heater: 1 bar lit on the temperature bar (diagnostic LED lit) | 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. | DIY Safe |
N/A | Whale Water Heater: 2 bars showing on the temperature display (diagnostic LED on) | Overheat | Check there's water in the Water Heater; wait at least 5-10 minutes to let it cool before clearing the lockout. | DIY Safe |
N/A | Whale Water Heater: 3 bars showing on the temperature display (diagnostic LED on) | Low or high supply voltage (operating range is 10V-15V DC) | Check the battery voltage; if it's within range, check the connections between the heater and the battery, then clear the lockout. (Note: the source handbook's own text for this fault refers to 'the Space Heater' here rather than the Water Heater - reproduced faithfully as printed, possibly a copy-paste artifact in Elddis's own document.) | DIY Safe |
