Regarding the 4 dashes on the Caldera Spa display, I believe I have found the reason. My spa produced the same 4 dash error and I let the filter soak in 1.25 cups of TSP, Tri sodium phosphate in a 7 gallon bucket over night. The water turned almost brown even though the filter was very white looking prior to that cleaning! I am pretty sure that body oils clogged the filter and restricted water flow causing a shut down! Now after a week, there has been no shut down or 4 dash error! Yay! drof2th@aol.com
