check gas pressure possibly running out of gas

Your main bord model number and Revision. model 128 Revision 14. This will appear every time the system reboots.

if still has power check gas pressure if ok check burner tubes for blockage if unit tripps breaker check ignitor if lights but goes out check flame sensor

Unplug the keyboard membrane then power it up. That will prove the membrane.

ado is a code for stack flue temp set up if you look at a pentair chart you can find the procedure to change that

check gas pressure if too low will overheat and soot or burner tube blocked

Hi there! Either the buttons are dirty, broke, or damaged in a way that the button is not making contact or the digital circuitry inside has failed. There are no user serviceable parts inside of almost all heaters. You are being advised to not attempt to fix it yourself. All heaters have fail safe/s that typically will keep them from starting a fire when they malfunction so it should be fine to continue to use. Good Luck Mr.Mike

A dirty filter can cause low pressure and as a result, cause the heater's pressure switch to turn OFF. A dirty filter can prevent a heater from firing and it can also cause your heater to shut off before warming the water to the desired temperature. https://www.inyopools.com/Blog/the-most-common-pool-heater-problems/ troubleshoot https://www.youtube.com/watch?v=V8lbH-zVQ2k

one of the stats is faulty and or shorted circuit

Check the power cord for damaged wires. Check for a faulty breaker. Check power going up to the unit...If power stays on up to the unit then you have a short inside the unit someplace.

AFS stands for air flow switch meaning the heater doesn't know if the fan is working. If the fan doesn't turn on, replace the fan. If the fan turns on, replace the tubing to the air flow switch and check the wires to the air flow switch.

It's a reversing cycle to help free it if stuck. It's normal.

Attached is a diagram of this pump. First remove the pump and work backwards until you are able to remove the motor and back cover.

The pump is running at prime speed at start-up. Your highest speed (number on panel) might be much lower than prime. Try setting the rpm for the speed number you select a bit higher. You will need to know how to adjust and lock in the rpm you want.

After 30 minutes of use, feel the outside of the breaker that is tripping. If you feel heat on the surface of the breaker it could be the breaker is going bad. Have an electrician change the breaker and have him check the load on the breaker. My guess is, if the heat pump seems to runs fine for an hour but is tripping a breaker then it is probably not the heat pump.

eo1 error code indicates temp sensor failure. Replace temp sensor. If problem persists then replace control board.

Is there enough Water flowing through the heater?
Is the gas valve open or closed?
What is displayed on the control screen of the heater?

At 8 years your SFS sensor could be going bad. Changing the sensor is very easy and not very expensive. There is another issue that could be causing your SFS to trip, the heat-exchanger inside the heater could be collecting soot for any number of reasons. Change the sensor first and if your issue is still present call a pro to evaluate and clean your heat-exchanger.

I had same issue yesterday in the field. The sensor was bad in my case. After replacement of the Stack flu sensor my stack temp was only reading 80 degrees, a clear indication that the board needed to be replaced as well. Replaced board and the heater fired fine and the stack temp reading was normal, 300 degrees. To obtain a stack temp, after the heater fires hold down the pool or spa button until the temp appears in the display. It will time out after 10-15 seconds.
