On the control panel there is a “Mode” button that has three functions as indicated in the box. Press the Mode button until the screen reads “Service”, your are now in Service Mode. Once in service mode you can manually control all your equipment, filter pump, heater etc via the buttons on the control panel. Once finished press the mode button until the screen reads “Auto”. By doing this you will not have to change programming.

Hate to be that guy, but it's a 5/8 deep socket, not an 11/16... also, if you don't breach the filter and let the system drain down you will get A LOT of water when you pull any plug/sensor from the heater. Drain filter by opening the air relief valve, wait 5 minutes
Then take drain plug out of heater manifold. Once the heater drains you can replace what you need. DONT pull a plug or sensor when a pump running..

Does it matter which terminal the cables reconnect to?

[@MikeyPipesOrlando]

You gotta take a closer look at the wiring schematic

[@larrymicheletti4517]

I changed the ags and it still will not heat my front panel only shows service heater. The front panel will not light up. The only light is the service heater light. Any suggestions. Thanks

[@MikeyPipesOrlando]

Bad panel?

[@kennethbrandon1418]
