Boomerps2 Posted March 14, 2021 Report Share Posted March 14, 2021 Hello all, I am new here and figured this would be an excellent place to ask a question and get some advice. I have a 2011 Caldera Martinique hot tub that runs beautifully and has been a solid performer the entire time I've had it. One day I noticed the circulation pump was vibrating the entire tub so I figured I better get it replaced. I got the new pump and when I went to the tub to start draining it, I noticed the noise was gone. What happened was the pump gave out completely and tripped the breaker. Reset breaker and pump does nothing. Turned off the breakers, drained the tub and getting ready to install this new pump. Question: Would the circulation pump giving out and tripping the breaker damage the heater at all given the water stopped moving through the heater? Does this typically damage the motherboard in these situations? Anything I need to check before I install this new pump? Quote Link to comment Share on other sites More sharing options...

RDspaguy Posted March 14, 2021 Report Share Posted March 14, 2021 Depends on the control system. Post a pic of the board. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted March 14, 2021 Report Share Posted March 14, 2021 Oh, Caldera. An IQ control has no fuses. The dual breakers provide circuit protection. Quote Link to comment Share on other sites More sharing options...

Boomerps2 Posted March 14, 2021 Author Report Share Posted March 14, 2021 How full does the tub need to be to test this newly installed circulation pump? Quote Link to comment Share on other sites More sharing options...
Boomerps2 Posted March 14, 2021 Author Report Share Posted March 14, 2021 Okay, circulation pump works great however heater is not turning on and the status LED for the heater is red. What do I need to do? thumbnail (1).jfif Quote Link to comment Share on other sites More sharing options...

Boomerps2 Posted March 14, 2021 Author Report Share Posted March 14, 2021 Okay wait, what color is the status light supposed to be on the heater? The temperature is rising and the tub is heating. When I plug the circulation jet with my finger and let go, hot water spits out. Went from 50 degrees to 54 degrees in a half hour. Outside temp is 30 degrees.

RDspaguy Posted March 14, 2021 Report Share Posted March 14, 2021 It's heating, and the led indicators are on/off. 1 Quote Link to comment Share on other sites More sharing options...

castletonia Posted March 14, 2021 Report Share Posted March 14, 2021 On the display, if the word "power" is constant and the temp is going up, its heating. If "power" is blinking, then you have an issue. The word "ready" will appear once the water temperature is within 2 degrees of the set temperature. 1 1 Quote Link to comment Share on other sites More sharing options...
Boomerps2 Posted March 14, 2021 Author Report Share Posted March 14, 2021 Just now, castletonia said: On the display, if the word "power" is constant and the temp is going up, its heating. If "power" is blinking, then you have an issue. The word "ready" will appear once the water temperature is within 2 degrees of the set temperature. "Power" is constant and the temp is rising. So I guess the "HTR" status LED on the mainboard is supposed to be RED. I assumed the red meant there was something wrong because the other two are green. Thank you RDspaguy and castletonia for the help. Much appreciated. Quote Link to comment Share on other sites More sharing options...
