Everything else seems to be working fine. When I turn off the power at the GFI box, then turn it back on, the display cycles through its normal cycle. It even lights the "heat" button after about 2 minutes.
Then, after about a minute, the "Dry" error message comes up and the heat turns off.
Both jets buttons work fine. The light button works fine. I am able to switch between the three modes (Standard, Economy and Sleep) and I keep it on Standard, which is the manual says to.
The temperature is set to 104 (the max) but the actual temp is 88F.
Does that help? Please let me know if there's anything else you need to know. I just know that with regard to the "Dry" error, the manual says to make sure and 'prime the pump' but I can't find anywhere that it tells how to do that.
