Question about Mr Steam Ms Super 1e Steam Shower Generator
You would need a multi-meter or voltmeter to trace the power path. Turn on the generator and wait until you hear the water feed solenoid stop. This means the water has reached the satisfied level and the pc board should have sent 24v to engage the contactor. On the actual pc board there is a section label "cont" which is what sends the 24v to the contactor the engage the heating element. Verify that you have 24v on the spade terminals going out to the contactor, if not then you may have a pc board issue. Second possibility is the contactor, if it is recieving 24v and it is not engaging then it's simply a bad contactor. Check the load side of the contactors with the blue wires. Lastly if these two steps check ok, then perform an ohm reading with a multimeter on the actual heating element(with the power off, put your two test leads on the two flathead screws that hold down the blue leads the go to the heating element). If you get an open reading then this may indicate a failed heating element. Pulling the heating element out on the left side panel will confirm any element failure.

probably scale build up from tap water unfiltered. Scale caused by mineral deposits will affect safety systems and auto cut offs in the unit

CU - 750 - the unit fills, element energizes, it doesn't make steam.
The element was installed two weeks ago. If the element went bad so soon, what could have caused this?

SOURCE: error code Prr
I had this problem, and checked the connections, emptied the resivour, and refilled it, and it had no effect.
To fix the problem, I ran the regular shower on hot for 10 minutes to warm up the shower chamber. Then, when I pressed the power button on the steam shower, it displayed "110" as normal.
The problem with "Prr" appears to be that the temp sensor is reporting a value out of range. Heating the shower chamber (and therefore sensor) provides a good value to the sensor, which then allows the shower to operate.
Try warming up your sensor by running the shower.
