No matter what the gas company says. If you are taking a menometer reading at the inlet to th gas valve, and you know that you have the proper lengths and diameter of gas pipe, And you have no flex pip on the gas line, then th gas company is wrong, and you need a larger regulator or a regulator adjustment.

Consult your installation manual to ensure you have the proper diameter gas line and so not use any flexible gas pipe .

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

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.

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.

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.
