This error is produced when the blower prover switch does not close after the blower starts, the control will stop the ignition and go into lockout. Automatic reset is immediate after the blower prover switch closes.

If you keep having this problem, contact a reputable service company, especially if it's under warranty.

The link to the owners manual is below, it references fault codes, etc..

Hope this helps.

Had a power outage yesterday now heater won't ignite. No error codes.


bo = 'Bypassed Operation'
heater is now controlled via your automation system.
Create a heat call, turn solar off if active.
Heaters should be set to auto on.

The CE code is showing on screen


Communication error


If communication between the ignition board and the display board is not established

within 3 s of power-up an error will be displayed. After communication is

established, if it is lost for 30 s, the error will be displayed. The error code will
be cleared upon a valid data exchange between boards.

Hi I hay a Hayward H400 pool heater. It is 2


This is a water flow problem and will be the by-pass assembly in the water manifold. Or their may be an external by-pass wich will be a valve bridging the inlet and outlet pipes for the water. This valve if you have it should be 80-90% closed to force water through heater. Before you do anything be sure to check to be sure the filter and baskets are clean. Often this is the problem.

Blower runs but no ignition then AO error code


Your problem then would be the pick up tubing and/or switch attached to the blower that closes once the blower is on to allow the heater to ignite. Pull the tubing and check it for dust or other debris clogging it and check inside the blower housing for the same. If you can test the switch under operation, you should see it remains open during start up which is why the burners won’t fire. If you do not find any obstruction (if you can, blow some compressed air thru too just to be sure) then you will need to replace the switch.
