DRY is an error code meaning that the heater is trying to run without water flow through it. You need to verify that the pump that supplies water to the heater is running and has good water flow. In most cases the pump is not running or has an air pocket in it if you just emptied and refilled spa. If it has an air pocket just loosen the union nut on the front of the pump to release the air then re-tighten and power spa back up. If the pump is running good and you have good water flow then the Flow / Pressure switch on the heater may be bad and need replacing.
