DISPATCHAlways disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Frequently Asked Questions: Atlantic E02
FAQ TREEWhat does error code E02 mean on a Atlantic appliance?
Atlantic error code E02 indicates: Boiler overheated and locked out.
What is the root cause of Atlantic error code E02?
The primary root cause for Atlantic code E02 is: Poor water circulation, blocked pump, or faulty overheat thermostat..
How do I fix or resolve Atlantic error code E02?
To resolve error code E02: Check that all radiator valves are open. Bleed radiators. Check pump operation. Reset the boiler.
Is it safe to clear Atlantic error code E02 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Atlantic code E02 persists, the physical component causing Poor water circulation, blocked pump, or faulty overheat thermostat. must be inspected or replaced.
How do I test electrical resistance for Atlantic code E02 using a multimeter?
Set a digital multimeter to ohms (Ω). Disconnect power and test Immersion / Air Heating Element & Klixon Thermostat across Between element terminals (unwired). Insulation to earth casing: >20MΩ (OL). Expected nominal reading is 25Ω–28Ω (230V / 2000W) / <0.5Ω (Safety Klixon closed). Tolerance: Formula R = V²/P (±5%). Any earth leakage reading below 2MΩ will trip the domestic 30mA RCD breaker..
What safety protocol must be followed before servicing Atlantic code E02?
Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
