the second pump (one on the left) is a single speed pump, so that is ok. the 3 relays on the bottom of the board are all for the heater, no pumps connect there. are you sure the spa is calling for heat? is the little icon on the screen lit up? make sure that the spa is in "standard mode" then and that icon is lit. if so, test for 240 combined volts (NOT FOR POWER TO GROUND ON EACH WIRE)on the red and black at the heater. if no 240 the relays are probally bad. if 240 is there the heater is bad.

try cleaning the connection between the pc board and the control panel. Power down the spa unplug the panel (its the phone cord lookin one on on upper right hand of board) clean and plug back in. Sometimes this will get it going again.

Thats a bad flow sw. If the flo is displayed solid on the screen it's the flow sw. If it's flashing flo, it's the circ pump.

Definetly sounds like bad contactors to me... Easy to replace, just make sure you get the right coil voltage.

I cut about an 1/8 inch slot in the center of the new clip where the strap rides, turn it sideways and feed the strap through the cut in the clip. It's hard to explain but easy to do.

probally from being banged around.. I'd bet the board is ok. replace the sensor.

I'll help also... for 2 weeks... aleast.

So your saying with the temp sensor in the water, it reads a 104- but the water is really 90... if so the sensor is bad.

Take my opinion for what's worth, I'm just another fool on the internet... But, I have been serviceing spas for about 10 years. I am Independent service company. I do not sell spas, so I have no loyalty to any brand per say. Cal spas are average quality at best. They use they same balboa controls as 80% of they spas out there. I can tell you I have seen a few new shells cracking around the led lights... And quite a few leakers that were brand new. I don't feel that their customer service is all that great either. Costco can't help you there, where a dealer could. Go try a sundance, jacuzzi, d1, marq... what ever. Look around, wet test, and ask questions... Find a dealer who will stand behind what he sells. 5-6 grand is alot of money these days! I'm not bashing Costco either, I feel that spas are kind of a specialty items that need a dealer with qualified people to handle any issues you might have.

In my opinion, I would shy away from cal spas at all costs...

I would definetly stay away from calspa... Out of the rest I would go for the certa.

Ivan, Make sure your in standard mode, Then set the cycles... I could tell how to set it but you'd be better off to print the manual which can be found here http://www.sundancespas.com/Communications...als/1997750.pdf Don't forget, your spa uses military time!

Since I was right, Do I get a free weekend at the cabin??? Just kiddin' Your welcome ~ Otis

My guess... It's set to economy mode. Press and hold the up and down temp buttons, then set to f3, It should stay on and heating in that mode...

if it has a "excellent" (brand name) transformer in it, that is the problem... replace it.

I seen a guy at one of the spa/pool shows a quite while back selling just this type of thing, it was a frame on metal ball bearing looking wheels. He was marketing them for showroom floor use which I thought was a good idea, but I don't know anyone who bought one. They kinda looked like this with wheels instead of pads. http://www.thespalevel-r.com/index.html

There are 2 boards, 6600-027 (This is the correct one) comes with rev4.50d and is for spas that have a circ pump, 6600-059 for a non-circ pump model, you can use this board and reuse you original eprom. But, I'd bet you don't need a pc board. Most of the time, It's a bad temp sensor on sundance spas that cause a watchdog mode. (part 6600-167) It's about 40.00 as opposed to 400.00 for a board. If I'm wrong your only out 40 bucks, but if I'm right you saved 400.00... definetly worth a shot, and you could change that sensor your self. Let me know if it works.

Is the light you are reffering to lit up in green on the top? If so, there is no problem. that should be lit, it indicates that there is good water flow. If the spa is flashing "flo" on the red temperature display that would mean there is an error and you should call service, otherwise your good. Your owners manual can be found here http://www.sundancespas.com/Communications...ls/99750850.pdf Good Luck Otis.

if I remember right, there is not one... it's all hartford loop deal on that one, if you just moved the spa thats probally why it got wet in there... (flipped on it's side to move).

http://www.spaandpoolsource.com/6500-75965...-speedpump.aspx here's one. make sure it comes with the bracket, or order one also.

Thats a hack move to me...Those pumps are not hard to come by... Sundance part# 6000-125, old part# 6500-035. both are interchangable. Although it will work if they changed the Eprom chip to a non-permaclear logic one . (Which I would make sure they did) I like a circ pump on them, because it's quieter, more efficent, better filtration and more ozone in the water. Is this being done at a cost to you? or is this under warranty from spring? Either way it's yours, and if you happy with it this way... leave it.

it's normal.

The circ pump does not "send error information" to the board... The flow switch reads if the circ is functioning correctly or not, if no flow threw the switch, then it flashes flo on the screen and disables the heater. From what you are describing, The circ pump is just probally bad. When the flo error was on the screen, did it go away when ever you turned the two speed pump on low? If so then its the circ pump... The circ pump draws water off of the pressure side of the 2 speed pump, when you turn the pump it will push water through the non-op circ, heater & flow sw... so the spa will heat when the 2 speed pump is on.

the one with the sunstar label is the new one.. it will have a flat lock on it, where as the other will have kinda like 2 prongs on it... they are both equal quality.

that looks right to me.. the open end is the air intake.
