Quick answer
EE on a Singer AC means the high water level alarm has triggered — the condensate drain pan is overflowing, usually because the drain line is blocked.
What EE means
The indoor unit has a float switch in the drain pan. When water rises above the safe level (because the drain line is clogged), the float trips and the AC displays EE and shuts down to prevent water from overflowing into your wall or ceiling.
Good news: EE is almost always a blocked drain, not a parts failure. A simple drain cleaning fixes it.
How to fix it
- Power off at the breaker.
- Open the indoor unit and find the drain pan underneath the evaporator.
- Clear the drain line. Disconnect the drain hose and flush it with water. Use a thin brush or wire for stubborn clogs. A wet-dry vacuum on the outdoor end works well.
- Clean the drain pan. Wipe out algae, sludge, and debris.
- Test the float switch. Gently lift the float — it should click. If stuck, clean around the pivot.
- Reassemble and test. Run the AC and confirm water drains freely and EE does not return.
Bangladesh monsoon tip: High humidity during monsoon season increases condensate production dramatically. Clean the drain line monthly during June-September to prevent EE.
What does the EE code mean?
EE indicates the indoor unit float switch has triggered due to high water level in the drain pan. The condensate drain is blocked.
Common causes
- Blocked condensate drain line (algae, dust, insects)
- Kinked or improperly routed drain hose
- Faulty float switch stuck in triggered position
- Drain pan cracked or misaligned
- High humidity causing excessive condensation (monsoon season)

How to fix the EE error
Open indoor unit
Access the drain pan.
Clear drain line
Flush with water, use brush for clogs.
Clean drain pan
Wipe out algae and sludge.
Test float switch
Should click when lifted. Clean if stuck.
Reassemble and test
Confirm water drains freely.
Safety first: Water and electricity are dangerous together. Always isolate power before working near the drain pan.
Part you may need: Condensate drain line / float switch
Drop a condensate drain tablet into the pan every 2-3 months to prevent algae growth and future EE errors.
Frequently asked questions
Why does EE keep coming back?
Algae regrows inside the drain line. Use condensate tablets every 2-3 months.
Can EE damage my wall or ceiling?
EE prevents overflow — but fix the drain promptly. If the float switch fails, water can damage your ceiling.
