spatech (the unreal one) Posted September 2, 2008 Report Share Posted September 2, 2008 This is caused by 1) clogged filters, 2) BLOCKAGE in system plumbing, 3) a non-functioning heater cicrculation pump, 4) power was not disconnected from spa before it was drained and 5) an air lock in the plumbing lines. I checked the filters and there was no clogged filters so I eliminated option #1 and option #4. Before you eliminate #1 based on a visual inspection, take out the filters and try to run the spa and see what happens. They don't have to look all "gummed up" to cause a restriction. How old are these filters? Quote Link to comment Share on other sites More sharing options...
Dan.The.Spa.Man Posted September 3, 2008 Report Share Posted September 3, 2008 Check the circ pump with your hand to see if it is vibrating and causing a ripple on the surface of the water. If there is no vibration, no ripple, and the pump is hot to the touch then it is shot. If it is working then I would replace the hi-limit thermistor. My guess is that the circ pump is dead.
