The age and over all condition of the heater would help. Try removing the Thermal Reg and see if it smooths out. If the heater responds, replace the Thermal Reg with a new one.

This issue sounds tricky. I recommend you callthe Sta Rite technical support at 888-782-7483 and they should be able to helpyou figure this issue out.

I hope this helps.

Check your stack flu sensor. Sensor can not be jumped. As soon as the heater fires hold down the pool or spa button until the stack temp appears. At 500 degrees the heater will shut off giving a code. The heater should not restart. I would also check for wire damage based on the description of your issue and the board restarting on it own. You may also have damage to the "user interface board" , hard to say with out on site trouble shooting.

Have any mice been inside the heater? If so check the burner. Some times the mice will nest inside the burner and it will need to be cleaned.

Try replacing the Temp sensor. You can not just jump it out, it needs to be repaced.

Water flow might be the issue. Check the Thermal Reg or any other external by-pass.

could be caused by many things. could be an flame sensor error, open saftey switch, stack flue error, etc look on back of circuit board and tell me what errors are lit up

These pool heaters have a very helpful and easy to follow chart in their users manual for problems such as this one. There are questions that you will need to answer that you cant answer unless you are looking at the heater. Below is a pdf version of the manual.

wet blankets are suspect when dried out as the water affects the insulation of the heating medium when a life is considered against the cost of a replacement, a new blanket will win hands down every time.

Today's gas appliances are designed to shut off when combustion problem is detected.For example if burner parts are dirty of clogged, the gas valve continues releasing gas, but not all the gas is burned.This caused potential explosion risk, with unburned gas in the combustion chamber and flueway.Call service tech to clean combustion parts, check pilot or igniter alignment, check gas control valve, and gas pressure, and bleed air out of gas line if needed.Search internet for product manual.

Are your legs really muscular? If yes, then yes.

could be the fan motor or check to see if a rust hole is giving you the whistle

Eo6 is the error code for stack flu sensor/switch. It threads into the exhaust pipe on the heater. Replace it and youre good.

eo1 is a thermistor failure. problem is either with temp sensor, wiring from thermistor to circ board, or the circ board itself

What is this error code? do you have any legend? this has no specific error codes as listed.

display board runs on 24 volts. make sure the secondary side of the transformer is putting out 24 volts. if the control pad is getting proper voltage and it doesn't work, replace the control pad and board

sounds like you need a new control board did mice nest under it that happens frequently

not a good move you will void warranty

you might want to add a bypass to the heater and not let the full return water through it this is called temp rise to slow the water down so it gets hotter

e05 error code means shorted stack flu switch or sensor. oder heaters have the switch, newer heaters have the sensor. make sure you know which one you have before ordering a replacement.
