I have a Sta-rite pool heater , model number SR200NA that is giving me a E01 Error code on the panel and the service heater light is lit on the unit. My owners manual does not specify the E01 error code in the owners manual? What actions should I take to resolve the problem. Heater is inoperable?

Between the two water pipes on the left side of the manifold is a two inch plug. When you take this plug out the thermal regulator assembly will come with it.It consists of "O" rings, a spring and what looks like a thermostat in a car. This is the probal bad part although it could be the spring also. You can get these parts seperatly or in a kit. If this is an older heater the kit is the way to go so you get all the nessary "O" rings and you will be covered on everything you need.

Your temp sensor has gone bad and will need to be replaced. It's a small tube that slides into the water manifold and you can follow the wires back to the board. Just unplug and set a new one in place.

The R5 is a sequence code in the boot up sequence where your error is occuring. There is nothing in the users manual for these pool heaters that explains this error. Your best bet, unfortunately, is going to be to call Sta Rite. Here is their customer service number: 1-800-831-7133
