E11 displayed and pump will not respond to keypad commands; may still run at a default speed.

Safety first: Disconnect power at the breaker before removing the control panel.

• Inspect keypad cable: Remove the front control panel cover and locate the keypad ribbon cable connection to the control board. Reseat the connector and ensure it is fully latched.
• Check for moisture: Look for condensation or water behind the keypad overlay. If present, dry the area and identify the source of leaks (e.g., rain, sprinkler spray).
• Visual inspection: Examine the keypad for cracks or delamination. If buttons feel mushy or unresponsive, the keypad membrane may be failing.
• Test with external controller (if available): If your AquaFlo pump supports external automation, connect it and see if the pump responds. If external control works but the keypad does not, replace the keypad assembly.
