Know Your Hot Tub

Identifying Parts in Your Hot Tub​

It’s good to know how your tub works, what the components inside are called and at times it will be useful for Dr Hot Tub to ask a few questions about parts of your tub before he gets there.

Use the image below to familiarise yourself with certain components before you call him.

How can I tell if my Tub has a leak?

Normally a Tub can loose an inch or so of water over a 4 week period with regular usage. If your Tub appears to be loosing more than this, look for tell tale signs such as water appearing around the floor of the cabinet that wouldn’t normally be there.

Mark the waterline with a crayon and monitor over a week, if the level drops more than 10mm the likelihood is you have a leak somewhere.

Always check however that your waterfalls/fountains are turned OFF when not using your spa!! This is a common problem for leaking tubs, as when the water from them hits a closed cover, it can run vback on itself and quickly drain the water from the tub.

Keeping your filters clean is vital for the safety and longevity of your hot tub. Make sure
you dedicate time to cleaning your filters to help keep the water in your hot tub fresh
and sanitised.

How often should I clean my filters?

This will depend on your usage, but we recommend
you clean them at least once every fortnight. Heavy
usage will mean your filters clog up quicker. However,
the situation is different when you fill your hot tub
for the first time, or whenever you drain and refill
your hot tub. In this instance, the filters may clog
up within three–four days because of the small
particles contained in tap water and any particles from
manufacturing/transport.

How do I clean my filters?

To clean your filters, we recommend using a hot tub
filter cleaner. For optimum results, spray the filter
evenly with an instant filter cleaner, wait 15 minutes
and then rinse the filter with a hose. An additional
recommended cleaning method is to soak the filters in
a bucket overnight with a filter cleaner solution. This
solution breaks down oils from the pleats and gives the
filter a deep clean. Please ensure your filter is air dry
before placing back into your hot tub.

What will happen if I don’t clean my filters
regularly enough?

Failure to clean your filters may restrict water flow
causing the hot tub to automatically shut down. The
following diagnostic messages may appear on your
touch pad if your filters are dirty; FLO, Heater Dry, LF,
DR, OHH, or — (two lines). To confirm that the filters
are the cause of the problem, remove them and run the
hot tub for a few minutes to see if the message clears.
If the message still does not clear, try switching the
hot tub off whilst the filters are removed, and then back on again.

General Maintenance

DAILY
  • You should check your sanitiser levels (Chlorine or Bromine) and pH daily or at least every 3 days if not weekly using your spa. 
  • Rub the waterline down each time you use your spa or at least once per week if not in use.
  • Always dissolve the chemicals independently before adding to the water and never mix chemicals together.
WEEKLY
  •  Remove the filter(s) from your hot tub
    and rinse with clean water (either use
    a hose pipe or clean them in a bucket)
    •Spread apart each pleat and rinse well to
    get rid of any dirt, hair or debris
    • Spray with rapid filter cleaning spray,
    then leave for 20 minutes before
    rinsing thoroughly.
MONTHLY
  • Clean your filters as normal but also us a ‘filter or cartridge cleaner’ to remove grease, body oils and other oily substances that reduce the efficiency of your filters.
  • Clean the pipes with Hot Tub Flush • Empty and clean the hot tub • Remove and install a new or clean filter • Refill water • Add chemicals and test levels • Clean hot tub exterior wall.
QUARTERLY
  • •Clean the pipes with Hot Tub Flush • Empty and clean the hot tub • Remove and install a new or clean filter • Refill water • Add chemicals and test levels • Clean hot tub exterior wall
Service Your Hot Tub Regularly

I think my Tub keeps tripping my electric breaker

If your electrics are tripping and your unsure what’s causing it, switch off your tub at the isolating switch then at the breaker at your main electric board. Then switch the breaker back on, then switch your tub on at the isolator. If it trips again it could be your Hot Tub however its always a good idea to ask a qualified electrician to check the supply first. Wires can come loose, MCB’s/RCD’s can fail and water can get into isolation switches, meaning it possibly isn’t the Hot Tub at all.

If it is your tub and its tripping as soon as you switch it on, its probably either a faulty pump, blower, heater or circuit board. Sometimes pumps can easily be fixed and Dr Hot Tub will make sure you don’t pay ‘over the odds’ with your repair if he can help it. If its tripping after its been running for a few minutes, its more than likely a faulty heater element. Again Dr Hot Tub will offer to repair it in the most cost effective way he can, he wont tell you you need a complete heater, it probably only needs a replacement element. However, if there is evidence that the heater is old and in a poor state, he will advise that you change the whole heater including sensors/pressure switch and O rings, saving the need for a return call out, saving you the inconvenience but more importantly saving you money.

I have a chinese tub I bought off the internet and cant find parts for it.

Dr Hot Tub does fix Chinese spas however if the part is for example a main circuit board he may advise that you replace the PCB with a more reliable, economical and durable Balboa system. He can do full refurbs for as little as £999 depending on how many pumps/blowers your spa may have. Most of the therapy pumps that the Chinese/Europeans put into their tubs are OK, however he would also offer to replace your Chinese pump with a compatible American one. They are a little more expensive, but tend to last longer than the Chinese versions.

If you have an older Chinese Spa its the Chinese PCB’s and heaters that really lets them down. If you replace it with a Balboa or a Gecko system, your actually making your Hot Tubs major component (the PCB, heater and control panel) as good and reliable as some of the cheaper American/Canadian/European spas on the market, some of which are actually manufactured in China but licensed in the USA. FACT!!!

European and Chinese Hot Tubs (Our Opinion)

A lot of European Hot Tubs are basically Hot Tub’s built in Europe with Chinese components and manufactured quickly with inferior materials and techniques. This makes them them appear to be ‘too good to be true’ when looking at the price tag. The likelihood is that it is ‘too good to be true’ and along with it, in a short period of time will come the common faults and problems associated with cheaper Chinese/European tubs such as expensive running costs, leaks, shell blisters, pillows disintegrating, cabinets fading, covers taking in water, detreating jets etc. etc.

Some Chinese spas are actually very well made and use controls such as Gecko, Balboa and acrylics from Lucite and Aristech. These spas are normally priced quite a bit less than there American counterparts, but offer much more for your money with regards to specification, making a good quality spa which should last many many years. Basically the golden rule is, if its cheap….AVOID!!

When you spend 1000’s of £’s on a Hot Tub, you really should expect it to last for many many years and look good, work well and run economically for those years. 

Dr Hot Tubs advice is Buy from an established, knowledgeable Hot Tub dealer who answers all of your questions and doesn’t just ‘look the part!!

DELAMINATION – Shell Acrylic Blisters and Bubbles

Delamination in acrylic is a result of poorly manufactured spas with inferior materials. This can cause blisters or bubbles in the shell below the water line which can also be caused by chemicals (especially chlorine and PH minus) being thrown into cold water or not dissolved properly, and because of this result in sitting on the acrylic surface. This is not something Dr Hot Tub will repair, however unless the blister is really soft (unlikely) and bursts, its purely an aesthetic uissue and should cause any real issues with your spa.
