And this is commonly caused by clogged debris and internal blockages.
This DR error code can be easily fixed by simply topping up the hot tub water level.
You can also run other simple hot tub troubleshooting steps if the water level is okay.
However, before you do this troubleshooting, it is important to turn off the GFI.
You also need to disconnect the hot tub heater and water pump power manually.
If the water level is okay, then check the cartridge filters and clean them properly.
It is essential to make sure they’re in good condition and not responsible for the DR error code on your hot tub.
Also, check that the jets are not filled with the debris and that the valves are all correctly closed.
You may also need to inspect the suction fitting and skimmer and be sure they have no blockages at all.
The Dr code can also appear if there is an air trapped inside the hot tub pump.
This problem usually happens after refilling the hot tub.
