Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
1 Flash | No Flame Detected | — | Check there's gas in the bottle and the gas line's clear, and use propane rather than butane below +5°C. Clear a lockout by switching it on, off, and on again, completing the whole sequence within 2.5 seconds. | DIY Safe |
2 Flashes | Overheat | — | Make sure there's water in the appliance, and give the heater 5-10 minutes to cool before trying the lockout reset: switch off, then on, within 2.5 seconds. If that doesn't clear an overheat lockout, remove the front cover so you can reach the PCB, then press the overheat thermostat's red reset button (it's a manual-reset type). | DIY Safe |
3 Flashes | Low/High Supply Voltage | Supply voltage dropped below 10V or rose above 15V. | Operating voltage at the heater should be 10-15V. Check the battery voltage, and if it's in range, check the heater-to-battery connections and the alternator or external charger. Clear the lockout by switching off then on again within 2.5 seconds. | DIY Safe |
5 Flashes | Other / internal fault | — | Try clearing the lockout by switching off then back on within 2.5 seconds - contact Propex directly if that doesn't work. | DIY Check / Tech Fallback |
