How to fix Midea P1
Drain the tray
Turn the unit off and unplug it. Set a shallow pan under the drain at the back, unscrew the drain cap, and let the water run out. Tip the unit back slightly to get the last of it, then refit the cap firmly.
Connect a drain hose for humid days
Midea's fix is to connect the drain hose and drain the water away. Run the hose downhill to a floor drain or bucket so gravity can do the work.
When to call a technician
If P1 keeps coming back, Midea says to call for service. A stuck water level switch is one possibility.
