Spa Control System Error CodesThere are many brands and models of spa control systems on the market. The majority have used or do use either the same or similar error codes for a similar symptom. Rather than list error codes under equipment or spa brands, we have decided to list them alphabetically and numerically for ease of identification. In most cases you should either contact us for further diagnostics, or contact a local qualified spa service technician to resolve your problem quickly and accurately. The following codes cover brands such as: Gecko Electronics, Balboa Instruments, Hurricane, Sundance Spas, Hercules, Brett Aqualine, Splash Pool Accessories, Vita, Spaquip, Ampac, Onga, Dimension One, Sweetwater, and many more. There are many other error and operational codes not listed here - please contact us if you need further info or data, or if you error codes that we can add. Causes of the common following fault codes(most common fault) - Dirty filters (the most common cause), blockage, switch failure, low water level, pump failure, broken wire Flow/Pressure Switch Closed Circuit - Switch failure, switch adjustment required, debris in switch, splashed /leaking water shorting connectors Hi-Limit Fault - Dirty filters, low flow, low water level, blockage, sensor fault, water entry to sensor or connector Temperature Sensor Fault - Sensor fault, pump heat interference, water entry to sensor or connector/corrosion Over Heat Fault - Same as sensor fault - sensor reads extremely high temperature 45C-48C.
