Hot Tub Maintenance Guide

The maintenance of your hot tub it to ensure the pump runs smoothly and also to keep your spa clean, safe and hygienic.

Change the Water…

Every week or so it is a good idea to change the water over, putting in clean fresh water. This is good as it will prevent any algae or bacteria building up. Just attached the hose and drain away somewhere safe, perhaps into a flower bed.

How To Disinfect Your Inflatable Hot Tub

Whilst a hot tub can provide hours of fun, it is vital to keep hygiene at the top of your priority list. This is so you can remove the possibility of spreading germ or recreational water illnesses. Regardless of the size of your hot tub, cleanliness is paramount.

To ensure that the water is clean and properly treated it should be cleaned after each use and this should be done through disinfecting to ensure that any microorganisms present are killed off. Your hot tub will come with built in filters which will need changing, these help prevent dead flies and hair from building up and being pumped around your spa. These filters do need changing every couple of weeks, dependant on the manufacturers recommendation.

In order to clean your hot tub there are certain items required to carry out an efficient and thorough job. A large bucket, a hose, a soft brush or hose and chlorine-based liquid disinfectant will all help to get the job done.

The first stage is to drain the hot tub and this is vital because water that has remained in the tub for some time can cause recreational water illnesses. It may seem a waste and time consuming but ultimately it is worth it in the long run.

You can use a bucket and soapy water, or we recommend the Miracle Sponge Eraser Pad, a clever sponge from Clearwater that makes it easy to clean any build-up on the waterline as well as removing grease and grime. This sponge can be used with the hot tub full or water, or when emptied. With this sponge there is no need to use and clear detergents or cleaning chemicals. This is perfect if there is some dirt that you can clean up without having to drain the spa.

Now it is time to let the tub dry out for several hours and after this time inspect that it is dry before storing it away. This type of cleaning should be carried out regularly and it is a good habit to get into as it keeps diseases at bay ensuring that all those who use it do not become ill.


If there is just one thing you should do is keep your filters clean and change them every regularly. The filters will clog up with dirt and particles preventing them building up in the spa or the pump itself. You can take the filter out that comes with your lay-z-spa and wash it under the tap with water, it is also a good idea to change the filter too with anew one, the better you look after your hot tub the longer it will last.

To ensure that they work as they should they have to be cleaned on a regular basis to ensure that any debris is removed along with dirt and bacteria. If the filter is not cleaned regularly then it increases the possibility of it harbouring harmful elements that could cause long term damage to the hot tub which can impact your health.

Cleaning the filters also helps to keep costs down as it can save on having to purchase new filters. In order to clean the filters there are some required items such as a soft brush, a power washer, a bucket, chlorine bleach and a spare filter.

The process begins once all the necessary items have been assembled and it starts with turning off the power to the hot tub. Now locate the filter, in most instances it can be found located close to the sprayer on the inside of the tub. The dirty filer can be removed by lifting the cover and then pulling out the filter, quickly replacing it with the spare.

Check the filter and look for any debris that may be lodged in there such as hair and remove it with the soft brush. To remove the risk of damaging the filter, carefully brush downwards along the seam of the filter and then spray the filter the pressure washer, spraying both the inside and outside until the water runs clear. Once this is done you are now ready to replace the spare filter with the original filter.

The hot tub water needs to be kept clean and free of germs. There are inflatable hot tub chemicals that can be purchased to clean the water. These chemicals will not damage the inflatable hot tub in any way. They will not eat away at the material that the hot tub is made from.

      • Toots

    Is it safe to use liquid chlorine in lay z spa and how much shoud i use for 670 gallons

  3. Donna

    Hi, I’ve bought a Paris spa second-hand an whilst it all works and the surfaces are for a, there is mould inside the inflatable walls. These walls are transparent so it really shows. So…a few questions please; does the spa water circulate inside this inflatable area? If not how did it get wet? The manual says to use the pump to ‘blow dry’ the inflatable…what does that mean? Lastly, can the pump run without water then, as I know it was told not to on my Bestway pool pump?
    Hope someone can help…thanks, Donna

    Keep getting error message E02 coming up,I have changed filter,drained spa and refilled it,checked pipes for kinks,back washed pump replaced filter housing,but still happens,we live in hard water area,the last time we used spa,two years ago it was ok

    • Ralph

      This happened to me constantly, but I soon solved it!

      Remove the filter/s and then run the filtration system for around 30 seconds or so – whilst it is still running, replace the filter/s.
