| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | Damage found on the appliance or electrical supply cord prior to or during installation | Component or power cord damaged during transit or handling | Don't install the appliance. A damaged electrical supply cord must only be replaced by the manufacturer, one of its service agents, or another similarly qualified person, to avoid a hazard - contact an authorised service agent or Whale Support straight away. | Professional Intervention Required |
N/A | Water heater control panel shows 'No Flame Detected' (number-of-bars-lit fault indicator) | No gas supply, empty gas bottle, blockage in the gas line, using butane below 5C, or a blocked combustion air inlet/exhaust flue. | Check the gas supply, making sure there is gas in the bottle and no blockage in the gas line. At temperatures below 5C, use propane gas rather than butane. Check the combustion air inlet flue and exhaust flue for blockages. Clear the lockout by pressing the water heat setting button and the plus (+) symbol button simultaneously for 3 seconds. | DIY Safe |
N/A | Water heater control panel shows 'Overheat' (number-of-bars-lit fault indicator) | No water in the appliance, or the water heater has not been given time to cool. | Check that there is water in the appliance. Whale recommends waiting at least 5 to 10 minutes to allow the water heater to cool, then clear the lockout by pressing the water heat setting button and the plus (+) symbol button simultaneously for 3 seconds. | DIY Safe |
N/A | Water heater control panel shows 'Low/High Supply Voltage' (number-of-bars-lit fault indicator) | Supply voltage at the water heater is outside the 10V-15V d.c. operating range. | Check battery voltage. If between 10V d.c. and 15V d.c., check connections between the water heater and battery. Check the alternator or external battery charging. Clear the lockout by pressing the water heat setting button and the plus (+) symbol button simultaneously for 3 seconds. | DIY Safe |
N/A | Water heater control panel shows 'Air Proving' (number-of-bars-lit fault indicator) | Combustion air inlet flue or exhaust flue blocked. | Check the combustion air inlet flue and exhaust flue for blockages. Clear the lockout by pressing the water heat setting button and the plus (+) symbol button simultaneously for 3 seconds. | DIY Safe |
N/A | Water heater control panel shows 'Other/Internal Fault' (number-of-bars-lit fault indicator) | Internal fault. | Attempt to clear the lockout by pressing the water heat setting button and the plus (+) symbol button simultaneously for 3 seconds. If this fails, contact Whale Support on +44 (0)845 217 2933. | DIY Check / Tech Fallback |
N/A | Water heater control panel shows 'General Fault' (number-of-bars-lit fault indicator) | Two faults have occurred at the same time, or at least five lockout-clearing attempts have been unsuccessful. | Turn off power to the water heater, check the water heater for faults, then turn power back on and clear the lockout by pressing the water heat setting button and the plus (+) symbol button simultaneously for 3 seconds. | DIY Safe |
