Dawlance inverter air conditioners show a code on the indoor display when they detect a fault or enter a protection mode. This is the complete Dawlance inverter AC error code list for Pakistan, with what each code means and what to do about it.
Dawlance AC Error Code List #
| Error Code | Description | Possible Cause | Solution |
|---|---|---|---|
| DF | Defrost Mode (not an error) | Automatic defrosting to prevent coil freezing | Wait for the defrost cycle to complete; no action needed. |
| E1 | Indoor Room Temperature Sensor Error | Faulty room sensor or loose connection | Check connections and ensure the sensor is secure. Replace if needed. |
| E3 | Outdoor Coil Sensor Error | Faulty coil sensor or wiring issue | Check the outdoor coil sensor and connections. Replace sensor if necessary. |
| E4 | Indoor Unit Fan Motor Error | Motor malfunction or blockage | Inspect the fan motor for obstructions. Contact a technician if unresolved. |
| F0 | Outdoor Fan Motor Error | Fan motor malfunction or obstruction | Clear any debris blocking the fan; consult a technician if needed. |
| F1 | Outdoor Module Protection Error | Module overheating or failure | Ensure good airflow around the unit. Let it cool down and restart. |
| F2 | Power Factor Correction (PFC) Error | Power supply issue or PFC malfunction | Inspect power connections; use a voltage stabilizer if needed. |
| P1 | High Voltage Protection | Voltage fluctuation | Use a stabilizer to maintain stable voltage levels. |
| P2 | High Discharge Temperature Protection | Blocked filters, airflow issue, or refrigerant problem | Clean filters and ensure good airflow; refill refrigerant if low. |
| EC | Compressor Overload Protection | Compressor overheating | Check compressor airflow and wait for it to cool. Seek support if it persists. |
| E8 | Communication Fault Between Display Board and PCB | Loose connections or display board malfunction | Ensure connections are secure. Replace the board if necessary. |
| F3 | Compressor Start Failure | Compressor or start relay malfunction | Inspect the compressor relay and call support if needed. |
| E9 | Low Pressure Protection | Refrigerant leakage or blockage | Contact a technician to inspect and refill refrigerant. |
What the most common Dawlance codes mean #
DF — defrost mode (not a fault) #
DF means the unit is running a defrost cycle to clear ice from the outdoor coil. It is normal behaviour in cold weather, particularly on heat-and-cool models running in heating mode. The unit will resume normal operation by itself after a few minutes — no action needed.
P codes — voltage and overload protection #
A P code means the AC has shut down to protect itself, most commonly because the incoming voltage is too high or too low. Check your stabiliser first. Repeated protection trips point to a supply problem in the house rather than a fault in the air conditioner.
E5 and E8 — communication errors #
These indicate the indoor and outdoor units have stopped communicating. The usual cause is the interconnecting cable — a loose terminal, corrosion, or damage where it passes through the wall. Isolate the power and check both terminal blocks are clean and tight before calling anyone.
F0, F1 and E4 — fan and motor faults #
These point to the fan or motor circuit. Check first that nothing is physically obstructing the indoor blower or the outdoor fan and that neither is stiff to turn by hand with the power isolated. If both spin freely and the code persists, the motor or its control circuit needs a technician.
How to reset a Dawlance AC #
A reset clears temporary faults — communication glitches, a one-off protection trip, or a code left on screen after the cause has gone. It will not fix a genuine hardware fault, but it is always the first thing to try and costs nothing.
- Switch the unit off with the remote and wait a few seconds.
- Turn the AC off at the circuit breaker or unplug it.
- Leave it isolated for 5 to 10 minutes so the control board fully discharges.
- Restore power and switch the unit on with the remote.
- If the same code returns immediately, it is a real fault — note the code and call a technician.
Which codes you can clear yourself, and which need a technician #
| Type of fault | Can you fix it? | What to do |
|---|---|---|
| Communication error between indoor and outdoor unit | Sometimes | Reset first. If it returns, the interconnecting cable or a board is at fault — technician. |
| Voltage or over-current protection | Often | Check your stabiliser and supply voltage. Repeated trips mean an electrical problem, not an AC problem. |
| Dirty filter or blocked outdoor unit | Yes | Clean the filters and clear debris and vegetation from around the outdoor unit. |
| Sensor fault (room, coil or outdoor sensor) | No | The sensor needs testing and replacing. Technician. |
| Refrigerant or gas-related fault | No | Usually a leak. Needs pressure testing and recharging by a technician. |
| Compressor, inverter module or PCB fault | No | Board-level repair. Do not attempt this yourself. |
