Daikin aircon EE error code
Use this Daikin EE error code guide to decide when to stop resetting, what to capture, and what to check before parts are quoted.
What does Daikin EE mean?
Daikin EE is listed as malfunction of drain water level in Ceiling Cassette, Ceiling Suspended, Inverter Split rows such as SM-TS3 matrix overview. The loaded row is source-backed by official diagnostic material. Confirm the exact model, series, or signal row before accepting a parts quote.
Blocked drain pipe, trap, or concealed drain route.
Float switch or drain-level protection triggered by water in the pan.
Drain pump, drain slope, or pan-level issue after clearing is attempted.
What to do now
Use these steps before running the unit again or approving drain or pump work.
Treat it as a fault signal
Stop using the unit if EE returns, water leaks, or the drain pan keeps filling.
Reset EE once
Capture the EE display, then stop the unit if water is leaking or the drain pan looks full. Power-cycle once only if the area is dry.

Source-specific guidance
These diagnostic-reference notes help match the code to the exact model. Electrical, refrigerant, wiring, resistance, and component checks are technician work, not DIY steps.
| Source detail | What it says |
|---|---|
| Source repair action | Stop the system if it smells burnt, leaks, or trips power; note the exact model and code before booking diagnosis. |
| Singapore / model note | Official Daikin SM-TS3 page-1 matrix row. The matrix gives the broad malfunction wording, but not the detailed cause table; confirm the exact model and installed accessories before treating it as final. |
What to check before repair
Use this split to separate safe evidence capture from the tests a technician should prove before quoting parts.
| You can check | Technician should confirm |
|---|---|
| Before resetting EE, take a clear display photo. | Confirm whether EE is drain overflow, float switch, pump, or water-level protection. |
| Capture the Daikin indoor and outdoor model stickers so the correct family row is used. | Clear and flow-test the drain route, then check pan level and float operation. |
| Note whether one room, several rooms, or the whole system is affected, plus whether it returns after one reset. | Test pump power, pump discharge, and slope on cassette or concealed units. |
What changes the next step
These clues decide whether the first check is room-side, shared outdoor-side, refrigerant-side, source-table, or model-family confirmation.
| What you see | What it points to |
|---|---|
| Only one indoor unit shows EE. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same EE fault. | The shared outdoor side, power path, communication trunk, or refrigerant circuit needs priority checking. |
| Water appears at the indoor unit or ceiling area. | Drain flow, float switch, pump, and pan level should be checked before running again. |
| The model family is different from the row you found online. | Use the model or series filter first; same-looking codes can still belong to different diagnostic tables. |
| The model belongs to Ceiling Cassette, Ceiling Suspended, Inverter Split rows such as SM-TS3 matrix overview. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
Drain clearing or pump decision
Daikin EE normally stays in repair scope: clear the drain, test the float or pump, and check slope before discussing replacement.
A blocked drain is usually a service-level repair if flow returns after clearing.
Pump or float-switch work needs part testing before replacement is approved.
Concealed drainage problems become labour-heavy because access decides the repair path.
