Error code Prr on Mr. Steam control unit. Steam generator starts for about 10 seconds, but no steam comes out and error code "Prr" shows on control unit. Any insights?

the first thing the generator should do when you hit the on button is fill. You will hear the water entering the tank. Once the water stops it indicates that the water has reached the water satisfied level, after which you should hear a loud click(your contactor engaging for the heat cycle, newer units will have all three light on the side lit). After this point is you aren't getting any steam after 5 minutes it probably means your heating element may be damaged. It would be best to remove the element at this point from the left side of the unit via 6 bolts and 2 wire leads. Any physical damage on the element such as a pinhole pop, burn mark, melting, or scar will surely prevent the element from heating

Hi my name is Mike I am with Mr. Steam Product Support. PRR is a code that shows up on our Steam Bath controls it was not used on our Sauna's. The PRR means there is a problem with the temp sensor on the control.please call me at 800-767-8326

I would venture a guess that the heating element has become intermittent with a short. Wasn't so bad before, but played heck with controller due to noise from arcing, but now have a dead short when heater reaches temperature.

Hi, kindly check the connection of your temperature probe down to the main board maybe its loose.

Try replacing the safety valve or look at your pressure controls which may be clogged.
