Pump or Waterfall Status Indicators

Overview

In the Gecko App, the pump or waterfall icons may display small status indicators that help you understand why the pump is currently running. These indicators show the operational mode or system function controlling that pump — such as heating, filtration, or safety checks.

Indicator meanings

H – Heating

When H is displayed, the pump associated with the heater is running to support the heating cycle. The heater is active, and the pump circulates water to maintain even temperature throughout the spa. The pump will remain on until the target temperature is reached and the heater shuts off.

CF – Check Flow

The CF indicator stands for Check Flow. This appears when the system is verifying water flow before allowing the heater to activate. The pump runs briefly to confirm proper water circulation and temperature sensing.

CD – Cooldown

The CD indicator means Cooldown mode is active. After the heater has completed its cycle, the system runs the pump for a short period to cool down the heating element. This is a safety feature — the pump will stop automatically once cooldown is complete.

F – Filtration

The F indicator shows that the filtration cycle is running. The pump is circulating water through the spa’s filter as part of a scheduled cleaning routine. This helps maintain water clarity and hygiene even when you’re not using the spa.

Summary table

Examples

In the app, these indicators appear next to the Pump 1, Pump 2, or Waterfall icons.
For example:

• A small “H” symbol on the Pump 1 icon indicates it’s running due to heating.

• A “CF” next to Pump 2 means it’s checking water flow.

💡 Tip: These indicators don’t require user action — they’re informational and part of normal system operation.
