Pump will not hold schedule or timer settings; clock resets after power interruptions.

Safety first: Turn off power before opening the control housing.

• Check user settings: Confirm that time and schedules are being saved correctly per the Kripsol manual; some models require a specific save/enter step.
• Inspect PCB battery: If accessible, look for a small coin-cell or backup battery on the controller PCB. Replace with the same type if depleted.
• Use external timer: As a workaround, control the pump from an external Kripsol time clock or automation system and leave the internal schedule disabled.
• PCB replacement: If the internal memory cannot retain settings, the controller PCB may need replacement.
