Spa Touchpad Error Messages & Codes
Revision 4.0.2, 18th October 2013
The messages and codes listed here are a combination of error, operational and reminders
Along-side each code is a brief description of its meaning.
Under no circumstances should you use this information to attempt a repair unless properly qualified to do so. We
have provided this information as a reference, and for qualified tradesmen to utilise as required.
Spa technicians – we can provide access to full diagnostic manuals covering these messages & codes, via an app
direct to your Android, iPhone, Windows Phone or Symbian Phone. Please ‘create an account’ on our website and
follow instructions listed in the ‘Trade Pages’ category. Alternatively we can email them to you on request (This feature
and access is only available to spa technicians).
Causes of the most common following spa / hot tub fault codes
Flow/Pressure switch open – dirty filters, blockages, switch failure, low water level, pump failure.
Flow/Pressure switch closed – switch failure, pump relay stuck
Hi-Limit fault – dirty filters, blockage, low flow, sensor fault, failed pump – senor reads 45C+ / 112F+
Temperature sensor fault – sensor failed, low flow
Over heat fault – Same as sensor fault, pump not running, relay failed – sensor reads 38-45C / 100-112F
Spa touchpad messages and codes are listed for various models from the following brands:
Chinese
Hercules
Hurricane
Spa-Tech
in.xe (and in.xe swim spa)
