Stuck in priming mode?

Upvotes

Hey everyone! So last night I was a moron left the hot tub cover open and the temp at 101 so it was running all night. When I woke up this morning I noticed it was stuck basically in PRIMING mode the jets would just go on and off water coming out. What’s usually the most common issues? I don’t think it’s air locked the only thing I can think of is moisture got into the control panel? Would love some suggestions.

Help needed: Hot tub temp regulating

Post image
Upvotes

I have a smart life hot tub (purchased in April 2026) and I can’t seem to keep the temperature regulated. It will go up to 106 F and I have to disconnect it bc I’m worried that it will burn the heater up. I have a hard time toggling with the temperature controller. Has anyone else had this issue or does anyone have any advice or tips?

Replacing 16 year old tub with one from Alibaba

Upvotes

We did the numbers and saw that our hot tub was 58% of our power consumption (We have a SPAN electrical panel + solar + batteries) and were torn on adding a battery and panels or what.

After running the numbers we decided to order a tub online from a manufacturer who uses Balboa packs/controllers and we had them customize the piping so we can add in a Climb8zone, retrofitting our current tub was about $6000 since we'd have to add a circ pump, new heat pack/controller and panel.

Anyone else purchase one from the factory direct vs a local show room? Any pluses or minuses?

We used a verified and trade assurance shop on alibaba and got DDP pricing included, will do a follow-up post when its delivery

But custom 550 gallon tub door to door was ~$5600 all in

Aquachek color scale

Post image
Upvotes

I am learning my new hot tub and trying to make sure I’ve got the chemistry where it belongs. I am a little stuck on reading the pH scale on my Aqua Chek test strips. It seems like the pH colors don’t match the scale on the back of the bottle, I believe everything is where it should be, but I’m really having to rationalize where the pH falls on the scale. Does anyone have an opinion as to how to read the pH in this photo? I snapped the photo right at the 15-second mark after dipping it.

Keep old J-230 or buy new

Upvotes

New here. Good info so far. I just got my 20-yr old Jacuzzi J-230 repaired… replacement wet end pump. Running good. My conundrum... I have put about $3k into this spa in the last 5-yrs or so. Do I stick it out and keep it and keep repairing, or, do I look at replacing? The shell is in good shape. I take good care of the spa using TFP recommendations. I have relatively new two motors, one pump, heater, new fuse and fuse block (surprisingly unobtainium and expensive to replace)and a repaired jet. Several leaks later and the low corner has nearly rotted out. Both diverters don’t work but at least they broke while still producing bubbles. Jets are strong. Simple spa but we like it. Thoughts?

Hottub water smells like body odor - replaced water twice/line cleanse solution - 1-2 months later, smells again.

Upvotes

So our hot tub has only what I can describe as a body odor smell. It is quite stinky.

For reference the tub is about a year old now, I changed the water once around April/may because it started to smell, it was fine for a bit, then smelled again. I thought I had maybe gunk in the lines because I forgot to use a line cleanser. So I emptied it again this time using a line cleaner chemical before and refilled. All was good. We used it for maybe 1-2 month (and went in literally once or twice), and I just went outside to check on it, smells like body odor.

I’m losing patience and ideas at this point.

The filters are clean/have been cleaned, plus they were replaced around the time I did the first refill, in April. I just replaced the Air Filter cartridge, though the previous one didn’t seem like it needed to be changed.

My chlorine is likely lower than normal because it’s one of the jacuzzis with the tru air ozone/UV bulb etc. so I would usually put two tbsp of chlorine in once a week and that was great for months, and it had lots of use.

Prior to doing the second refill and line cleanse I was dousing it with chlorinated shock, made no difference.

Is it something external? The cover? I don’t think so because if you get the water on you, the smell comes with it. I wiped down the entire interior and cover each time I did the refills with a tub safe spray. I use a shop vac to blow out whatever I could from the lines.

Any ideas?

Marquis hot tubs — good brand?

Upvotes

Someone is selling a marquis 8 person hot tub down the street from me. I got rid of our smaller round Nordic this past year as the family and kids have outgrown it. This seems to be a good price at 5k and only a few years old. Hooked up and in immaculate condition. Good buy?

Hot tub cover torn

Thumbnail gallery
Upvotes

Hi everyone,

I recently purchased a house (hurray), and it came with a hot tub. To tell you the truth hot tubs and pools were something in my no list for buying a house, but when we saw this house we fell in love, and the sound of a hot tub in winter sounded nice then (Canada).

After reaching a price agreement for the house, the previous owners added a clause of taking the hot tub as is. We haven't been able to test it yet, but we actually met the sellers who let us know it did work. Our neighbors also told us they used it quite regularly. Upon inspection, though, the cover is super worn, and we think that was the "as is" clause. More to come on that soon as we test it I guess. For now we've been dealing with some house repairs.

Anyway, my question is, is there any way for us to manually repair this cover, or should we just bite the bullet and buy a new one entirely? I imagine at its current state it will cost us a lot of electricity in the winter.

TLDR: Cover is worn/broken, can we replace this ourselves or should we get a new one?

Edit: formatting as I'm on mobile

Winter shutdown

Closing up early. Will completely drain, disconnect water lines from pumps and controller, blow out lines. Does anyone leave the tub uncovered so moisture/mold not build up under the cover?

Spa Pack Recommendations (Gecko doesn't support their products)

Upvotes

I have an old spa, manufactured by a company that's out of business. Over the years , I've replaced all the pumps and jets, now I need to replace the electronics. I bought a Gecko spa pack, and have installed it. I have many issues with it and have written multiple emails to Gecko tech support. It's clear from their slow responses that they aren't reading my emails, but rather scanning them briefly, and responding back with very partial instructions. So now it seems that the only way to get my spa working again is to return the spa pack back to Gecko and buy one from a company that supports their products. Has anyone had a good experience replacing their spa pack? What brand would you recommend?

Rotomilled vs Acrylic

Recently ordered a tub. A Lifesmart Leganza 6 person unit. Very excited about it. I know the negative opinions about the texture, but would rather be a little grippy than slick. Anyone have any experiences with rotomilled tubs and their longevity?

Zagłębione jacuzzi – najczęstszy błąd #5: źle przygotowane zasilanie

Post image
Upvotes

trzeba zaplanować przed wykonaniem niecki, płyty fundamentowej i tarasu.
To brzmi oczywiście, ale w praktyce bardzo często spotykamy sytuację, w której wanna jest już zamówiona, taras prawie gotowy, a dopiero wtedy pojawia się pytanie:
„Gdzie właściwie ma wychodzić kabel?”
I zaczynają się problemy.
Nie każda wanna ma takie same wymagania
W zależności od modelu SPA może wymagać innego sposobu zasilania, zabezpieczeń oraz przekroju przewodu.
Dlatego nie warto przygotowywać instalacji „na oko” ani na podstawie wymagań poprzedniej wanny.
Najpierw wybieramy konkretny model.
Dopiero później przygotowujemy instalację według jego dokumentacji technicznej.
W Wellterra przy każdej realizacji określamy wymagania dla konkretnego modelu SPA jeszcze przed rozpoczęciem prac budowlanych, tak aby elektryk i wykonawca tarasu dostali jasne wytyczne.
Kabel nie powinien wychodzić przypadkowo
W przypadku wanny zagłębionej bardzo ważne jest miejsce wejścia przewodu do urządzenia.
Jeżeli kabel zostanie wyprowadzony po niewłaściwej stronie, może później:
● kolidować z konstrukcją wanny,
● utrudniać dostęp serwisowy,
● wymagać prowadzenia go dookoła niecki,
● albo oznaczać konieczność ponownego wiercenia w gotowym betonie.
Dlatego punkt zasilania ustalamy jeszcze na etapie projektu niecki.
Zostaw możliwość serwisowania instalacji
Najgorszym rozwiązaniem jest zalanie przewodów lub połączeń w miejscu, do którego po wykonaniu tarasu nie będzie żadnego dostępu.
SPA jest urządzeniem technicznym.
Po kilku czy kilkunastu latach instalacja nadal musi być możliwa do sprawdzenia, naprawy lub wymiany.
Elektrykę wykonuje elektryk
Samo przygotowanie fundamentu czy niecki może wykonywać ekipa budowlana.
Podłączenie SPA powinno jednak zostać wykonane przez osobę posiadającą odpowiednie uprawnienia i zgodnie z dokumentacją konkretnego urządzenia.
Prąd i kilka tysięcy litrów wody to zdecydowanie nie miejsce na improwizację.
Najlepsza kolejność prac?
Model SPA → dokumentacja techniczna → projekt niecki → lokalizacja zasilania → beton → taras → montaż wanny.
Nie odwrotnie.
Po wykonaniu tarasu praktycznie niczego już nie widać.
I właśnie dlatego najważniejsze błędy przy zagłębionym jacuzzi powstają zwykle dużo wcześniej — zanim sama wanna pojawi się na budowie.

High flow filter

Upvotes

I recently bought a celtic hot tub model luna 114. Ive noticed when the filter is in the jets are pretty weak with some of the smaller ones not hardly blowing anything. If I take the filter out and let it run for a few seconds the jets work perfect. The filter is new and clean. I understand there will be some restriction with filter but to not make some jets even move water is excessive. Is there a high flow filter I can use or something else I need to do?

I'm not sure if it's from a kid bathing suit or is this glitter is from a copper reaction or if the heater is corroding. Anyone ever experience this?
