How to Fix Error E11

DIY Fix Basic gas supply and ignition checks

  1. Ensure the gas supply valve to the heater is fully open (no partial closure).
  2. Check that the gas hose/connection is not kinked or blocked.
  3. If you have recently disconnected the gas hose, try restarting the unit several times to remove air from the line (common for gas heaters with ignitor-based systems).
  4. Confirm that the heater’s power is stable (plug/socket/breaker) and restart the unit to see if error clears.

Technician Only Professional inspection of ignition / gas system

  1. Verify correct gas pressure at the heater (using manometer) as per manufacturer spec.
  2. Inspect ignition components (ignitor, flame sensor/probe) for wear, fouling, or misalignment.
  3. Test gas valve operation and check for blockages/flow issues.
  4. Confirm that internal safety devices (e.g., flame rollout or thermocouples) are functioning and not falsely triggering shutdown.

Parts needed: ignitor / flame sensor, gas valve assembly, pressure regulator / gas line components
