How to Fix / Troubleshooting
Safety first: Disconnect power before handling the control board. Static discharge can damage electronics.
- Power reset: Turn off power for at least 5 minutes, then restore. Sometimes a full reset can clear transient memory errors.
- Factory reset: If available in the Kripsol installer menu, perform a factory reset of settings. Re-enter required configuration parameters.
- Surge protection: Install a suitable surge protector on the heater’s power supply to prevent future damage.
- Board replacement: If E20 persists, the control board’s memory is likely damaged. Replace the Kripsol main control PCB and configure according to the installation manual.
