Heat pump water heater is one of the best equipment for hot water needs, but still make sure that friendly and beneficial to the natural environment. In particular, this product also helps you save costs. They can be used for many different purposes in addition to water treatment such as: Air conditioning, distillation, drying, more flying ...
In the course of using the machine, some errors can be caused by the impact of internal or external factors. To help customers understand more about the product, we will summarize the common errors in the use of heat pump water heaters for your reference as follows:
- The heat pump is not working
Failure of the heat pump may result from the following: No power is supplied to the machine, fuse burns, the wiring point is loose, the AC circuit of the equipment in the heat pump is broken.
- The pump is working but there is no water circulating and the pump noise is too loud
The reason is: The water supply system for the pump is malfunctioning, causing a shortage of water. Excessive air emissions in the water system put pressure on the water flow, causing them to decline in number. The water valves are closed, so it is not possible to provide the necessary amount of water for the heat pump to work. Dirty water pipes or water filters cause the water to become blocked and inaccessible to the heat pump.
- Compressor is not working
The compressor may not be working due to a broken compressor contactor, or a loose cord. Power supply for the compressor is not available. At the same time, the compressor is too hot, so it automatically switches to high and low pressure. Lack of flow or protection of water with too high temperature also makes compressor not working.
- Improper water temperature
The cause of this error is the lack of refrigerant in the heat pump. At the same time, the heat exchanger cooling process is not efficient, or due to lack of flow in the pump.
- Exhaust fan is not working
This is also one of the basic errors that heat pumps often encounter. The cause of this situation is the exhaust fan is burnt, the screws of the fan are loose and unable to maintain operation. In addition, the fault of the heat pump contactor also causes the exhaust fan to stop running.
- The compressor generates too much noise
The compressor suddenly generates a lot of annoying noises, which may be due to: The refrigerant has leaked into the compressor, or a part of the compressor has been damaged that is still working. , but make a loud noise. Lack of lubricant in the compressor is also the cause of this situation.
- The compressor works but there is no hot water
The refrigerant leak is too much, making the heat pump water heating performance affected. In addition, some parts of the compressor malfunction can cause the situation.
- Lack of water to supply heat pump water
This situation often occurs with long-term heat pumps and customers do not pay much attention to checking the water source, as well as the plumbing system. Specifically, the lack of water supply is due to insufficient water flow in the source tank, dirty water filters leading to clogging.
- The compressor stops working right after the power is turned on
The reason is that the air pressure in the system is too large, so the protection switch will automatically turn on to protect the machine, to avoid fire. Too much refrigerant in the machine also leads to the compressor stopped working after turning on the power. Besides, abnormal voltage or high voltage, low voltage conversion problem is also the cause of this situation.
- The circulating pump is working but the fan is not working
At that time, the customer should check the fan capacitor and fan motor for any unusual signs? If so, it is necessary to immediately repair or replace it before returning the heat pump back to service.
- The discharge pressure is too high
The discharge pressure of a heat pump is too high, either because the refrigerant is too much in it, or the air in the system condenses too much. In addition, lack of flow and too many scales in the condenser also cause this situation.
- Continuous low pressure
Continuous low pressure may be due to the lack of refrigerant, the circulation and the temperature of the water, and the surrounding environment is low.
- Fire fuse after closing the adapter
The reason is that the compressor is clogged or burnt. In addition, you should also review the electrical system as this could be a sign of a power leak.
