E0

Lockout

Retry / recycle lockout

Failed to sense flame after the retry limit (typically three trials). One-hour-class auto retry.

Walk E0 in Diagnose

4 plates — walk the one on the cabinet

First check

1 Airflow before you touch the limit

On Daikin DM80VC a limit is airflow or overfire until proven otherwise. Do not replace the limit first. Filter, blower wheel, A-coil, and the heat-speed setting for THIS motor (tap, model plug, or communicating CFM — not a sister SKU chart). Watch one full try: inducer, HSI, valve, flame, µA.

Expect: Rise in the rating-plate window. Static vs this cabinet’s blower chart.

The rest of the walkthrough is Diagnose.

On the plates

  • Watch one full try: inducer, HSI, valve, flame, µA.
  • Gas supply and manifold low then high.
  • Do not keep resetting — find which step dies.
  • Full try at the percent it is attempting. A valve that will not come off minimum looks like E0/E6.
  • Gas supply, HSI, rod, ground.

Plates that use E0

Same number, other makers

E0 on Daikin is not the same code on these plates.
