Troubleshooting · Skimmi Troubleshooting
Why is my Dolphin Skimmi beeping with a flashing red LED?
Short answer: Beeping and a flashing red LED can signal a blocked wheel or temperatures too low or high for charging.
Count the red flashes in each 2-second cycle and check the app error. Three flashes mean a blocked wheel; one or two mean a temperature alert.

The fix
Step by step.
If your Dolphin Skimmi beeps and its LED flashes red, count the flashes every 2 seconds. The pattern identifies a blocked wheel or a temperature alert.
3 red flashes every 2 seconds: blocked wheel
This pattern means something is caught in a wheel. Follow these steps:
-
Step 1Check which wheel is blocked
Read the error message in the app to identify the stuck wheel. Remove any object or hair caught in it.
-
Step 2Clean the filter tray
Empty the tray, then rinse it with water.
-
Step 3Try the wheel-unblocking setting
You can also change Wheels Unblock to Increased Force in the app. This setting uses more power and reduces the Skimmi's total cleaning time.
1 or 2 red flashes every 2 seconds: overheating or freezing risk
When the Skimmi is too hot or too cold, it beeps and displays an error message in the app. This alert does not mean the skimmer is malfunctioning. It is a protective feature that pauses battery charging. If the Skimmi overheats, charging remains paused until its internal temperature cools down.
- 1 red flash every 2 seconds: The pool or outdoor temperature is below 39°F or above 131°F. Charging stops.
- 2 red flashes every 2 seconds: The battery temperature is below 39°F or above 131°F. Charging stops.
-
Step 1Address the temperature alert
If the Skimmi is too cold, move it to a sunny or warmer spot. Before putting it back in the pool, confirm that the pool temperature is within 39-131°F.
If the Skimmi is overheated, put it in the pool for 1-2 hours and gently splash a little water onto the solar panel.
-
Step 2Adjust the daytime schedule
In the MyDolphin Skimmi app, set Day Cleaning, the cleaning duration, to 20-30 minutes. Set Day Pause, the interval between cleaning periods, to 1 Hour during the day. These settings help preserve the Skimmi battery.
-
Step 3Turn off the beeping if preferred
To silence the alert, open Device Setting in the app and switch Alert Sound off. You can change this setting again once the weather cools down.
