Hot Tub Repairs! Every so often, your hot tub or spa will unfortunately encounter some errors and need a hot tub repair. For most of us, we just like to enjoy or hot tub and do not know much about how they work or even how to repair them!
As with everything, it could be one of a large number of problems, that all have multiple solutions, sometimes cheap, sometimes expensive.
My little guide should aid troubleshoot some of the most common problems and help you isolate exactly what is wrong, then either fix it yourself of call in an engineer for the hot tub repair.
Warning: Electricity is obviously dangerous, especially when water is present. Hot tub Repairs sometimes have to be made by an electrical or spa engineer to ensure correct and safe fitting.
Make sure all power to the hot tub or spa is unplugged before you start your spa repair. Turn it off and shut down at the mains also.
Basic Tools you may need for your spa repair: Screw Driver, Grips, Socket set, wire cutters, a voltage meter for checking ohms and resistance etc. Basically just a good array of basic tools, nothing too expensive needed.
Your spas topside control panel will usually tell you all the most common faults. I have compiled a list of the most common fault codes:
PD – The spa is running on battery backup.
OHH – Overheat. hot tub shuts down.
FLO – Flow error, can be a number of different reasons – research needed
ICE – Water is far too cold to be started up
SN1 – Hi-limit sensor error
SN3 – temperature sensor error
DRY – The heater is sensing there is inadequate water flow
HFL – Large difference between heater sensors
Sometimes the spa will just say error, that’s when some manual fault detection will need to used. If your hot tub doesn’t run at all or even pump or heat, the problem is most likely to be in with the electrical system of your spa.
The most important and usually most expensive parts are the control box, pumps, blowers and heaters. The secondary and less expensive components for a hot tub repair are the ozonator, filters and the jets / Plumbing.
It’s best you take an organised approach to checking all these and eliminating the possible causes. If you get through all of these and still have no idea then you can always get advice from and hot tub parts company.
These guys can usually help you over the phone with advice, if not then it’s time to call an engineer.
sometimes even a damaged shell can caused problems, Minor damage to the hot tub shell, for instance a small crack that leaks water can cause low flo problems if the spa is not at the efficient water level.
if you do figure out which part its faulty and needs repairing then always shop around! if you call an engineer, he may try to fit
a part that he will supply, that can be twice as expensive as one you could buy from a dedicated parts store.
