Dimplex Electric Fireplace E2 Error — Sensor Fix

What Does This Error Mean?

E2 on Dimplex indicates the temperature sensor isn't reading correctly.
The unit disables heating; flame and ember effects typically still work.
Power off at wall switch, wait 5 minutes, restart.
If E2 persists, sensor replacement is needed — Dimplex authorized service.
Dimplex's higher-end units typically warrant repair (50-150 USD parts plus labor).

Affected Models

  • Dimplex Optimyst
  • Dimplex Revillusion
  • Dimplex IgniteXL
  • Dimplex Synergy
  • Dimplex BLF series

Common Causes

  • Temperature sensor failed
  • Sensor wire disconnected
  • Connector pins corroded
  • Heat-cycle wear
  • Controller sensor input damaged

How to Fix It

  1. Power off and wait.

    Turn off via wall switch.
    Wait 5 minutes for full controller reset.
    Some E2 events are transient and clear after this fresh boot.

  2. Restart and test.

    Restore power.
    Try heating function.
    E2 returns immediately = hardware failed.
    E2 returns after some operation = intermittent fault, usually connector issue.

  3. Use flame and ember effects alone.

    Dimplex flame and ember effects (especially Optimyst water-vapor models) are sophisticated.
    Use without heat for ambiance.
    The visual experience is unaffected by E2.
    Optimyst models use water vapor for incredible realism — heat is supplementary.

  4. Don't disassemble.

    Dimplex units are sealed for safety.
    Disassembly voids warranty.
    Service-tech work only.
    Don't attempt DIY on the heating system.

  5. Contact Dimplex support.

    Dimplex North America customer service: 888-346-7539.
    For warranty service (typically 1-2 years), they'll arrange repair.
    Out of warranty: Dimplex-authorized service centers handle sensor replacement.
    Cost: 100-200 USD typical.

Frequently Asked Questions

Are Dimplex Optimyst units repairable?

Yes — Optimyst is Dimplex's premium technology and worth repairing.
The water-vapor flame system is unique and well-engineered.
Dimplex maintains parts availability and authorized service for these.
Repair makes sense even on units 5-10 years old.

Will the water vapor still work?

On Optimyst models, yes — the water vapor system is independent of the heater.
You can still enjoy the ultra-realistic 'flame' (actually water vapor and LED lighting) without heating function.
This is one of Dimplex's best features and works regardless of E2.
