Spa Hot Tub Watkins Hotspring Tiger River Caldera No Fault Heater How To The Spa Guy

[@Vegapops]

Great information! What is the part number for the new heater assembly. I have a hot springs prodigy

[@CFraser]

We found other videos that show how to replace the end cap on Watkins heaters. That's where my leak was.

[@spaguyhowto7417]

This video is 6 years old.. At that time there were not heaters or parts.. Now there are plenty of both..

I have a Hot Springs Sovereign hot tub circa early/mid 2000's. I emptied and refilled the tub due to some nasty water. When I attempted to restart the spa, the GFCI on the plug tripped. I reset the plug and it tripped again. I have thoroughly cleaned the filters, checked the connections, and did a visual inspection for "burns" or obvious issues. NOTHING. When I reset the GFCI, I can run the jets without any issues...however, when I turn the jets off, a few seconds later the GFCI trips again.

I’ve got an older Hot Springs Sovreign model with a 110 volt heater. The heater body leaks but the element is good. What would be the modern replacement for this heater? I don’t want to rewire it for 220 volts if I don’t have to. Your recommendation would be appreciated. Thanks Dave

Do you know about a nordic R.M.F. heating element?

Under the heater cover (two screws at side) there's a thermodisc capillary overheat cutoff switch which has failed open circuit in the unit I'm looking at, leading to no heating. Bridging the spade contacts to bypass it when powered up the heater draws just over 6A at 245V so it appears the 1.5KW heater element is actually good (measures about 3 ohms when this cutoff is bypassed)... Any ideas where we can get a replacement thermodisc please to repair the heater - it's labelled model 10H11 and believe opens at 150F, I've had a good google search but not coming up with much? It seems silly to spend so much on a new heater when its just this thermal cutout that's failed (presumably run dry with airlock/pump failure). One of the relays controlling the heater had also gone high resistance contacts too - that's been replaced - trying to think of the failure mode of this lot - the circulation pump had also died. I've put it in the freezer at the moment to see if it ever closes contacts or whether contacts have pitted and become high resistance (not measuring anything though, completely open). I don't think I can satisfactorily open it to make any such repair. Also wired across this cutout switch was a small DBK PTC (EB51 1/18) heating element (32W?) which appeared to be placed just on the inside top surface of that cutout switch - possibly as a diagnostic feature as I don't see any other purpose to it (unless it's to heat up the thermodisc to try to help reset somehow)? Any ideas on that please? Thanks for reading,. hope you can help :)

UPDATE: put capillary thermodisc in freezer and it reset, 0 ohms so contacts are good - put over a flame and tripped with a fairly loud snap... didn't reset (supposedly 40F/22C below trip temp), froze again and was ok - so it clearly isn't able to reset normally at room temp. But it'll get by as a patch on the problem for now as long as there are no more air locks that could cause heater to reach the 'trip' temperature (supposed to be 150F/65C - will try heating a pan of water to check as it's a safety device) - the fact it needs to be frozen to reset is a secondary concern :) I'm now sure the PTC heater element across this cutout switch is there to act as a latch - to ensure that the thermodisc does not reset once tripped - the heater keeps it tripped until power is removed and allowed to cool.

We just refilled our hot springs hot tub and when we hit the reset on the plug, you hear the pump turn on but after a couple seconds everything shuts off. When we unplug the heater from the control board, everything else runs fine. When the high limit reset is continuously pressed in, the heater stays on but as soon as the button is released, everything shuts off.

Hi, my no fault 1500 has died (failed ohms test - no continuity), where can I buy the alternative unit from and what would the price be? Great videos by the way.

[@jbhiroler]

Great video! I have a Tiger River Spa that has given me more headache than pleasure. I can hear the heater circulation pump kicking on, then turning off. After a bit, it just goes into "fault". When it does work the water is sometimes super hot, and sometimes luke warm. Any advice on if I start with the pump or the heater? (Or replace both??) Thank you!!!! Your videos are really informative.

[@Germatti13489]

We go through this every year and have to reset the button on the heater but this year we can't seem to press the button in.

[@spaguyhowto7417]

If the button will not reset you will have to replace the heater..

[@Germatti13489]

@@spaguyhowto7417I apologize, I should have worded that a little better. I should have said that the reset button hasn't popped out, I can turn the Jets on but it does not heat. I am wondering if it isn't the part that shuts the heater off if it doesn't recognize water pressure? I have forgotten the name of it but I know that you will know!😁

[@alexrbombon]

Im currently having an issue that everything shut off, circulation pump not working and the water go cold. I checked the breaker panel and it was normal the red light on the plug is off and will not reset

[@spaguyhowto7417]

What brand tub? If the circ is off you have diagnose why it is off.. If the hi limit tripped and will not reset then there is something wrong with the hi limit.. You really didn't give enough information for me to tell you much..

[@chrislindsey3393]

Still buying Watkins no faults without a problem....hopefully they still keep making em

[@spaguyhowto7417]

Yes they have started making them again. There was a few years you couldn't get them and these were the thing then the company went out and other companies started making them..

[@Mongoloidmike987]

No fault heaters that fail should be called yeah its our fault
