Ninja Foodi Er2 Error — Pressure Sensor Fix

What Does This Error Mean?

Er2 means the Ninja Foodi's pressure sensor has reported a fault. The cooker cannot confirm whether pressure inside the pot is at a safe level, so it stops operation as a precaution. This is most often triggered by a dirty or blocked pressure sensor port.

Affected Models

  • Ninja Foodi OP300
  • Ninja Foodi OP400
  • Ninja Foodi OP500
  • Ninja Foodi OL500

How to Fix It

  1. Release pressure and unplug

  2. Clean the pressure sensor port

  3. Check the sealing ring

  4. Inspect the pressure valve

  5. Power reset and test

Frequently Asked Questions

Can Er2 appear even when the lid is sealed correctly?

Yes. Er2 is a sensor fault code, not a lid-detection code. Even with a properly sealed lid, a clogged or malfunctioning pressure sensor will trigger Er2. Cleaning the sensor port usually resolves it.
