Question about Pool & Spa
ICE is an issue with the cold water temperature. I'm guessing that you filled the spa with cold water, or turned the spa off and the water cooled right down. In ICE mode, the spa turns on the pumps and keeps running until it's satisfied that the water is not going to freeze, this can take some time.
DRY is an error that occurs when there's insufficient water in the heater, or a lack of water flow through the heater. This is commonly caused by either an air lock, a low water level, or a problem with the pump.
Is the pump circulating the water through the heater as per usual? If not, can you hear the pump running? If the pump is running but there's no water flow then suspect an air lock.
To remove an air lock, you can slightly loosen the pump union, or heater union to release air from within the system, much like when you have to bleed a radiator. As soon as water starts to come out of the union tighten it again. If you have an air lock you should hear the air escaping from the union prior to the water starting to leak out. If you heard air, that's great, try the spa again.
