Electrolux Professional LPIn Error Code

Boiler level sensor problem

What does Electrolux Professional LPIn mean?

LPIn means the SkyLine oven has detected a problem with the boiler water level sensors, and the affected cycle stops. The oven can keep operating in convection or ISG mode. The cause is usually limescale shorting the level sensors or insulation issues, and the manual's first remedy is a cleaning program with rinse and descale.

Symptoms

  • LPIn displayed and the cycle stops
  • Oven still runs in convection or ISG mode
  • Boiler-based steam cycles unavailable
  • Often follows heavy scaling

Common causes

  • Humid lime short-circuiting the boiler level sensors
  • Insulation issues with the boiler level sensors

Diagnostic steps

  1. Run a cleaning program

    Run a cleaning program including the rinse and descale cycle to clear the boiler water-level path.

  2. Use the specified tablets

    Use 2 C25 tablets only, following the procedure in the Operating Manual.

  3. Use convection meanwhile

    Continue cooking in convection or ISG mode while the boiler issue is being resolved.

  4. Repeat the descale if needed

    If scaling is heavy, a second descale may be required per the manual procedure.

  5. Call Service if it persists

    If the problem persists after descaling, call Service.

When to call a professional

If LPIn remains after running the rinse-and-descale cleaning program, contact an Electrolux Professional service centre. Boiler level sensors and their insulation are internal components; a wiring or insulation fault, as opposed to simple scaling, needs trained diagnosis. Repeated level-sensor alarms can leave the boiler unusable, so professional repair restores reliable steam operation safely.
