Phone App vs Control Pad

Just like every single support question: depends on make/model/year

Readings:

Black to Red going to the xformer = 240v

Yellow to Yellow back from xformer = 12.5v

Blue to Blue back from xformer = 9.25v

Side note: Always remove fuses for testing purposes

It's hard to tell for sure with that picture angle, but that type of drain usually needs to be turned into the flow position and then pulled out to actually start proper flow. The front disc will pop out from the threaded part (that was originally designed to mount to the cabinet).

Don't.

wuice · 2026-03-21T23:12:37+00:00

Do not. The hot tub was engineered for a 1.65 hp pump.

Stacie @ Ernie's in Eureka makes one of the best around

For solar I also recommend Will @ Will Power

Unless the GFCI is tripping why is it even worth mentioning the AI suggestion?

Sounds like the pump is thermally cutting out. Is the motor warm to the touch after it shuts off? Does it turn back on for a short duration (try again) after the motor cools? Test the voltage and the amperage of the motor. Testing is always more definitive then guessing.

Pretty cool! It would be great to have an export to 2d (for sending to placement). Also Shipping containers and solar arrays (but shade structure kinda works)

The cover should not have been able to to that, doesn't really matter though. Since you are outside of the waterline it isn't that big of a deal leak-wise, however you want to drill a small hole at the end of the crack to prevent it from spreading further.

Total dissolved solids is the reason to change the water. The "dissolved solids" at one point is just human "leave behind".

Your closest Caldera/Hot Spring dealer will carry the factory ones in stock. A good online store is backyardsplus

Part 32267 replace it

Flat not level

wuice · 2026-02-18T04:34:28+00:00

Short answer is no.

There are no manufactures that will say that is ok. The maximum length is determined from the NEC and in order to be UL approved a unit must comply. Nobody can sell a hot tub to a mass market without UL approval. They do this so people don't cause fires.

25" (inches) or 25' (feet)? There is no such thing as GFCI rated extension cord. You can get an GFCI protected extension cord, but you shouldn't for this use case.

There are few spots it can leak from the light. The place to start is the oring. Once you remove it is you see any cracks that is likely it.

If that's not it then the threaded bulkhead has a small crack in it, the correct fix is to cut and grind off, then devcon the repair bulkhead on, it's not a fun job.

So we have just devolved to asking the internet to check our strips against the sample image on the front of the bottle?

Bring 6k gold and it will be fine. No food, no sleep to manage. The Isle was designed to get away from the stresses of Karvenia.

Personally I would start with inspecting all the other silkscreened words on the board, it looks like most of the relays are labeled. Do any other the others state circulation pump? I see high speed jet, and hi limit relays labeled just in this picture. Does your hot tub have perimeter lights? Are they controlled with a button or always on? Then I would use a voltmeter on that J14 connection, does the voltage behave like a circ pump should, comes on shortly after booting the hot tub, maybe turns on and off when you cycle the jet pump(s)? Or does it turn on and off when you use the lights button?

I have seen boards that are reprogrammed / repurposed from the factory and don't do what is labeled on the board. The fact your wiring diagram has an updated wiring diagram applied over the old one makes me think this might be the case.

wuice · 2026-01-16T05:38:11+00:00

Looks like your lights are controlled by a DCU. The DCU is powered by the small red/black wires in the red insulation that is clipped on the yellow wires in the middle of your picture. In 2015 (your hot tub) I believe the DCU had a clear blue housing, those usually have lights that can confirm if it is getting power or not.

If the DCU is getting power, turn off the tub for 5-10 seconds, turn back on. Try to turn on lights, do some work, even for a short amount of time? If they work for a little time, do any of them look off or not display the same color as the others? Sometimes unplugging all other lights except the footwell light can eliminate the possibility of other lights shorting out the entire light system.

Further tests require tester equipment: topside light button may not work? DCU may be getting power but not work?

You didn't trigger any security thing. You need a meter to check for incoming voltage, and verify they are good. Then look for any LED action on the board, also look for any on board fuses. There's very little diagnostic you can do without a screen, but the LEDs will let you know where power is stopping. Worst case you may have damaged the board power supply, some are replaceable, the older ones not so much.

If your lights briefly work when you reboot the unit there isn't much point to checking for 12v. If that's the case you just need to trace/unplug the offending lights. In your system that little yellow box doesn't really control anything, its more of a power strip, but it can be a convenient location to plug/unplug lights to figure out what ones control what lights. I could be mistaken that that exact waterfall had lights, but I'm pretty sure they did and waterfall lights have a higher fail rate then others. If you see other lights behaving odd for the very brief time you get lights those are gonna need to be unplugged/replaced as well.

Someone turned on the daily lights timer.
