Gree Air Conditioner E9 Error Code

Condensate overflow protection on Gree air conditioners.

E9
Easy DIY fix

On GREE units with a factory-installed condensate pump, E9 means the water level in the drain pan rose high enough to trip the overflow protection. The pump has stopped keeping up, usually because the drain line or pump is clogged.

Compatible models

GREE's FAQ ties this code to models with a factory-installed condensate pump. Check your manual to see if yours has one.

Also shown as

On units without a factory-installed condensate pump, GREE lists E9 as a heat-mode status where the indoor fan is delayed, which isn't a fault. Check your manual to see which kind you have.

Safety first: unplug the air conditioner (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Gree E9

  1. Turn the system off

    Switch the unit off at the breaker. Water near electrical parts is a reason to cut power at the panel, not at a plug.

  2. Check the drain line outlet

    Find where the condensate line leaves the house. Clear any mud, insect nests or kinks you can reach at the end of the line.

  3. Let the pan drain

    Give the pan time to empty, then restore power and run the unit in cooling. Watch for E9 over the next hour.

When to call a technician

If E9 returns, have a technician clean the drain pan and pump. The pump sits inside the unit.
