Welcome to our forum.
On my display the "dr" code stands for inadequate water level at heater. Sounds like it might be airbound. If the tub is filled try running the pumps to purge the air out.
How can you have a new tub and not know the manufacturer? Where did you buy it from? Tileman
We have a new 2 us tub, not sure of the brand, but now that it is set up and wired it will not heat up. the control panel flashes dr and we do not know what that means. we have checked that the 220 wiring is done correctly and both pumps work but the heat won't go above 57 degrees. can any one help us?
