I have a Cal Spas tub. It is about 7 yrs old. Every oncei n a while I get the dY error. I will push a button and it will go back to running normal for sometimes a few weeks other times a few days. This error 'says' Insufficiant water level detected in heater. The tub is filled to the proper level. The filter is clean, so Im not sure what is causing this error. I DID replace the heater a few years ago. I do not remember if I used the new water sensors that came with it or if I just screwed in the old ones. Could these two sensors, which are screwed into the heater tube on each side be the cause of a false low water reading?

Hi I just replaced my brainbox and heater in my 30 year old spa with a Balboa VS500 unit. I am regularly getting a "DY" low flow code and have had no luck troubleshooting. The small 3/4 circ pump is installed after the filter, is it possible that there isnt enough flow through the filter to keep the heater supplied?? Any other ideas anyone has? thanks Dan
