Saw the error code and saw it was most likely the stack flue sensor. Ten minutes after receiving my part, I had my spa running hot again!
Pools hot again
For my heater, it would come on for about 30 seconds then shut off and give me an EO5 error code. Holding down the Pool On button, you get the stack flu temperature. Mine was saying 80 and flashing 40 occasionally. This sensor was the problem and very easy to replace.
Takes only five minutes to install. Only tools needed are a screwdriver and a wrench. Fixes E05 error messages on Pentair Mastertemp pool heaters
My Pentair heater wasn't working, Pentair specailist said to try replacing the flu- found it here for the least expensive! Got within 5 days, install was simple and the connections were redesigned so less likely to get moisture at connection.
