Possible Causes
Corrupted control firmware, Internal memory error on PCB, Incorrect filtration schedule settings, Power interruptions during programming
How to Fix / Troubleshooting
Safety first: Disconnect power before extended troubleshooting.
- Factory reset (if available): Consult the NetSpa user manual for the specific model to perform a factory reset of the control system and filtration schedule.
- Reprogram filtration: After reset, set a simple filtration schedule (e.g., 2 hours twice per day) and test operation.
- Stable power: Ensure the spa is connected to a stable power source without frequent outages or tripping breakers.
If E11 persists after a full reset and reprogramming, the main control PCB may have a firmware or memory fault and will likely need replacement.
