Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
1 | Water Heater shows a 'Check gas supply' fault (1) | No gas in the bottle, a blockage in the gas line, or using Butane below +5°C | Confirm the gas bottle has gas and the line isn't blocked, switch to Propane over Butane below +5°C, then clear the fault using the Water Heater's own white Reset Button followed by the iVan Control Panel's OK button. Switch to an electric heating mode instead if the gas problem can't be fixed straight away. | DIY Safe |
2/3 | The Water Heater displays a 'Gas overheat fault' (2) or an 'Electric overheat fault' (3) | The Water Heater isn't completely full of water | Open a hot tap and run the pump until the water flows smoothly, let the heater cool for around 10 minutes, then clear the fault using the Water Heater's own white Reset Button followed by the iVan Control Panel's OK button. | DIY Safe |
4 | Water Heater shows a 'Voltage Supply fault' (4) | Supply voltage at the Water Heater is outside the operating range (source states 10V-12V d.c., though this may be a printing error for 10V-15V d.c. as stated elsewhere in the same handbook) | Check the battery's voltage, and if it's fine, inspect the wiring linking the Water Heater to the battery plus the alternator or external charger. Clear the lockout using the Water Heater's own white Reset Button followed by the iVan Control Panel's OK button. | DIY Safe |
5 | Water Heater shows an 'Air pressure fault' (5) | Airflow through the Water Heater's flues is restricted | Check both flue ends (they're outside the vehicle) and remove whatever's blocking them, then clear the fault with one press of the Water Heater's own white Reset Button followed by the iVan Control Panel's OK button. | DIY Safe |
6-11 | The Water Heater displays one of six numbered internal-fault codes (6-11): Thermistor, Flame simulation, Relay sense, Start-up, Configuration, or Switch fault | An internal fault with the heater | The Water Heater's own white Reset Button, followed by the iVan Control Panel's OK button, clears the lockout with a single press. Contact Whale Support at +44 (0)845 217 2933 if the fault remains. | DIY Check / Tech Fallback |
15 | Water Heater shows a 'General fault' (15) | Either two faults have happened together, or five or more attempts to clear the lockout have already failed | Power the Water Heater off, check for any recurring fault, power it back on, then press the white button on the Expanse and confirm using the iVan Control Panel's OK button. If the fault won't clear, contact Whale Support at +44 (0)845 217 2933. | DIY Check / Tech Fallback |
