How to clear Gree vrf L3...
Gree L3 error indoor service
If your Gree VRF indoor unit is displaying L3, it typically means Water Full Protection. This fault occurs when the indoor unit detects that the condensate drain system is full or cannot drain properly.
To troubleshoot:
Check whether the condensate drain pipe is blocked or kinked.
Inspect the drain pump (if your indoor unit has one) and verify it is operating.
Check the water level (float) switch for a stuck float or faulty switch.
Make sure the drain hose has the correct slope and water can flow freely.
After fixing the drain problem, turn the system OFF for 5 minutes and then restore power. The L3 error should clear automatically if the fault is gone.
