How do I get rid of the sandy feeling on the inside of the hot tub?

I emptied and cleaned my hot tub, filled it up and put chemicals in it. When i got in it later, the inside area feels like sand particals around the whole inside.

I'm thinking I put too much of some granual chemical in? It has always been really clean and nice when I've emptied and cleaned it before.

I don't know what I'm doing wrong. I use the test strips to check the levels of chemicals.

Cross trainer 2008 Jet # 1 won't shut off

Jet #1 will not shut off.Press the button once it goes high speed, press again goes back to low speed.Temperature is good, filter cycle is set at 6 hours, Was set for standard operation I changed it to sleep(slp) mode but no change, pump continues to run.

The pump 1 would run low speed for either heating or filtering for longer periods. With filter cycles duration set at 6 hours and that the system would perform 2 cycles per day, this would result in long runtime of 12 hours a day. The heating modes such as Standard, Economy or Sleep do not change its filtering runtime. This only affects how it maintains/operates heating. The default filter setting would be 2 hours, totaling 4 hours per day. Unless the amount of use was resulting in water clarity conditions while water chemistry properly maintained, many cases the default 2 hour duration setting (4 hours per day) is adequate.

Hello, i have a to 7.2 without the circ. Pump. Can I add one after?

What is this part on my twilight series hot tub?

There is a piece of PVC, maybe 1/2 inch diameter, that is open ended with what appears to be a rubber check valve. It is inside the cabinet.

It’s behind the right panel of the tub if you are looking at the pumps. There is also a soft tubing nearby, probably the same diameter. When the pumps come on water sprays out of the PVC “check valve”. Nothing comes out while normally circulating, just when jets are started.

This part does not show up in any manual or parts list.

I’m pretty sure I need one. Can I plug it short term until I find a new one?

Due to the unusual times, Master Spas has made some changes in its manufacturing processes in order to ensure that we can meet rising demand for spa and swim spas. We have informed our dealer (and our local retail) about these changes that we are making in our production process. These changes are designed to help streamline the production process and allow us to meet demand in a more timely manner. If you have any questions, please feel free to contact our Customer Service Department at 800-860-7727.

What is standard delivery?

Does that mean they deliver and install. All we have to do is have the electrician set up the right power source.

Hello! The dealer will typically only put the spa in place. It’s the responsibility of the customer to make sure it’s hooked up by a certified electrician per the owner’s manual.

Filter placement

I have a Twilight 7.2 Series Spa I took the filters out the first time not sure what is the proper spot for each filter to back in? Does it matter if one is in the right side or the left side??

1 answer
By Admin on Behalf of the Company #1642094
For your Twilight 7.2, you would want to make sure that your Eco Pur filter is located on the side closest to your topside control panel. This will give you the best release of minerals throughout your spa to eliminate micro-organisms and remove heavy metals. Thanks for asking! Hopefully this helps.

model and info needed

Hi we have an older Freedom Spa Master Spa it's blue in color and it's seats 6 and it has a corner filter pma 40 I have no idea what model it is because of the fact the tag on it on the outside is unreadable due to its age, the spa is fantastic! Love the Spa we love it but I just cannot find out any other info on it and the filter tag is gone so if you could help me that would be great.

I can tell you it's darker blue has founder on one side where feet jets meet milter opening. It seats six. Has brown outer shell.

The control button panel says freedom and has one light and two buttons and temp button four in total. It has two jet control turn knob's on the sides one by the neck massage seat and one on the lumbar side outer ledge.

Thanks for reaching out! From this description, it’s hard to tell which model you have. If you could send us some photos of the spa as well as the model info of the internal main electrical control system, we can try to see if we can match it up. If you need help with parts and such, we ask that you send photos of the components so we can try to help provide part numbers for replacements (if electronics, we would need to see the model info from manufacture labels on the components). We can be reached at Thanks!


I did not check on my hot tub for about two weeks due to illness. When a checked a few minutes ago there was very little water in the spa.

It is raining so I can’t tell where it is leaking. It is a Twilight Series and it’s about six months old and I have had no problems with it up to this point. I have turned the power off but we may have freezing temps tonight.

What should I do? Sent from my iPhone

By Admin on Behalf of the Company #1622089
Unless the water is leaking out very quickly (say as fast as trying to fill it – or where it is dropping below the filters within a day), it is best that you try to keep it running and top off the water as needed in order to prevent any freeze damage from occurring before a service tech is able to look at the spa. In order for service to be able to find the leak, it should be running with water if at all possible. If your spa has been installed and placed in conditions where freezing could occur, we ask that you take appropriate measures to protect your spa from potential freeze damage by providing some means of warmth within the spa cabinet or immediately winterizing your spa. One of our customer care representatives will be following up with you on this. Thanks for asking!

Why is the ozonator in my therapool deep not centrally but laterally installed? This is not mentioned in any brochure.

Master Spas does not answer me.

Aren't the shells all prefabricated and should therefore be identical in construction? Who can answer this question?

1 answer
By Admin on Behalf of the Company #1590280
Thanks for your question. Every shell we make is custom made in our factory. We make over 40 different models and while we build them with the same process, no two will be alike as they all have different curves in the seating design and layout. This means each model will have unique placements for the therapy pumps and other items including the ozonator. We’ll be reaching out privately to inquire more and to make sure you don’t have any other questions.

how to set spa for California use.

TS 8.2 spa overheats with temp set at 82.

1 answer
By Admin on Behalf of the Company #1351610
Thanks for the question and I'll start off with some clarification. During the warmer months of the year, or if you live in a hot climate, it can be common for the water temperature in your hot tub to be higher than what you actually have the temperature set at. This is caused by a number of things including the heat generated by the pumps of the hot tub while in operation, the outside temperature, the intensity of the sun heating up the cover and cabinet of your hot tub, and the actual insulation and design of your hot tub being to retain heat and not lose it.
That being said, remember there is no "air conditioner" for your hot tub to magically drop the water temperature. Instead there are a few simple steps you can take to get the water cooler. First, you may need to drain some of the water in your hot tub. This will allow you to then add cooler water from your garden hose. You may also add a few bags of ice to the water for a potentially faster way to cool the hot tub. You can also leave the cover partially open for a few hours during the night once the sun has set and temperatures have dropped. This allows the hot air to escape.
Some other tips include setting your filtration for lower time cycles. Again, the longer the pump(s) are running, the more heat they generate. Finally, depending on your installation, some people will shade their hot tub using an outdoor patio umbrella. Hope these tips help and if you need anything else please let us know at customer

What is average monthly energy cost for 14' and 17' ?

1 answer
By Admin on Behalf of the Company #1780503
We don't currently have an estimated energy cost for either of those models due to the fact that it varies depending on the climate the swim spa is located in as well as the amount of use it's getting.
