English
Meaning
Indoor unit drain pump or water level switch fault. The air conditioner produces condensate during cooling. When the water level is abnormal and cannot drain properly, protection is triggered to prevent water overflow.
Common Causes
- Drain pump motor seized or damaged
- Float switch stuck and unable to reset
- Drain pipe clogged causing water backup
- Drain pump capacitor failed
- Water level sensor circuit open
Self-Check Steps
- Check for water overflow or drip marks under the indoor unit.
- Open the indoor unit front panel and check whether the drain pump is blocked by debris; clear any obstructions.
- Use a thin wire or specialized tool to clear the drain pipe and ensure smooth drainage.
- Check whether the float switch moves freely; clean any scale buildup around the switch.
- If the drain pump does not run at all, contact Hisense after-sales service to replace the pump.
