1. Is there any foreign object blocking the outlet pipe of the water pump, which prevents water from being pumped out? We suggest trying to unblock the outlet pipe of the water pump;

2. The water level switch is broken, causing the air conditioning fan control motherboard to have no working signal for the water pump;

3. The water pump is broken. If possible, it can be disassembled and cleaned.

No, because it is necessary to use a water pump to send water to the water distributor and wet the wet curtain to achieve cooling effect. If there is no replacement equipment for the water pump, the water cannot send sufficient response to the wet curtain, which will result in the cooling fan not having cooling effect, which is equivalent to spending thousands of dollars to buy a large fan.

The reason why the water pump always breaks down is mostly because there is no water in the bottom basin, and the water pump will idle, causing it to burn out. So it is possible to check if the water inlet of the machine has been blocked by green moss in the water. If it is a quality issue with the water pump itself, then it can only be said that the brand of the cooling fan you have chosen is problematic
