Check your model first

  • Digital 206A-406A
  • Digital Low NOx 207A-407A
  • Professional 268A-408A
  • Above-Ground 106A-156A
  • Digital 206A-406A / Low NOx / Professional / Above-Ground

Match the model on your equipment label to the linked manufacturer documentation. The same code can mean different things across model families.

Quick answer

Reduce high flow rates with a manual bypass valve (target 105-110 deg F outlet). Check U.G. movement, air starvation, improper venting, and insects or debris clogging burner intake ports.

Severity: high · DIY difficulty: easy

Safety

Stop at the exterior: power-cycle at the disconnect, clean the filter/basket, and check for obvious water-flow blockage. Pool heaters combine gas piping, 240 V wiring, and (on heat pumps) refrigerant — burner, control-board, and sealed-system work requires a licensed technician. If you smell gas, shut the gas valve and leave the area first.

What Sooting means

Reduce high flow rates with a manual bypass valve (target 105-110 deg F outlet). Check U.G. movement, air starvation, improper venting, and insects or debris clogging burner intake ports.

Code meaning varies by series

  • Digital 206A-406A / Low NOx / Professional / Above-Ground: High flow rates (add manual bypass valve; adjust outlet to 105-110F), U.G. inoperative, air starvation, improper venting, or insects/debris clogging burner intake ports (clean burners).

First checks before service

This page currently documents the safe reset triage. If the code returns, use the linked source manual or a qualified technician for code-specific diagnosis.

  1. 1. One-time fault event (power disturbance or transient sensor reading) common DIY

    Check: Power-cycle at the breaker/disconnect (or unplug for CPAP), restore, and run the system while watching for the code.

    Fix: If the code does not return after a full run cycle, the fault was transient — monitor, no repair needed.

  2. 2. Fault persists after a clean reset occasional pro only

    Check: If the code returns immediately or every session, note the conditions (startup, heating, after rain).

    Fix: A persisting code points at the component the manual assigns to this code — that repair is technician territory.
