Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
1 | No flame detected on Whale Space Heater | Not enough gas getting through, or air trapped in the supply line | Make sure the bottle has gas in it and the line isn't blocked, and use propane rather than butane once it's below +5°C, then clear the lockout. | DIY Safe |
2 | Overheat on Whale Space Heater | Air ducts or vents blocked or restricted | Make sure nothing's blocking or restricting the air ducts and vents - Whale suggests giving the Space Heater 5-10 minutes to cool down before you try clearing the lockout. | DIY Safe |
3 | Low/high voltage supply on Whale Space Heater | Supply voltage outside the 10V to 15V operating range (measured at the Space Heater) | Check the battery's voltage - if it reads between 10V and 15V, check the wiring between the Space Heater and the battery, and check the alternator or any external charger, then clear the lockout. | DIY Safe |
4 | Combustion air fault on Whale Space Heater | Blockage in combustion air inlet flue or exhaust flue | Check both the combustion air inlet flue and the exhaust flue for blockages, then clear the lockout. | DIY Safe |
5 | Other/Internal fault on Whale Space Heater | Internal heater malfunction | Try clearing the lockout first; if that doesn't resolve it, get in touch with Whale Support directly on +44 (0)845 217 2933. | DIY Check / Tech Fallback |
Solid | General fault on Whale Space Heater | Either two separate faults have happened together, or five or more attempts at clearing the lockout haven't worked. | Press the Space Heater's own red Reset Button to clear the lockout. | DIY Safe |
