Air heat pump water heater 3 major fault

With the improvement of living standards, it has become a trend to promote "hot water civilization" life, provide environmental protection, health, safety, and a large number of continuous hot water, and these are precisely the inherent advantages of air source heat pump water heaters; With the improvement of residential conditions, there are more and more high-rise residences and large-area houses. Air-source heat pump water heaters are easier to integrate with homes than other water heaters because of their small size, easy installation, and sustainable water supply. Products that combine and meet water demand.

So what kind of failure can air heat pump water heaters generally appear?

First, the analysis of the compressor surface frost failure: It may be caused by the expansion of the temperature sensing package off, or failure of the expansion valve, or chip stuck, temperature setting problems, or refrigerant preparation is not enough.

Diagnosis: Re-adjust the inside of the device, replace the thermal expansion valve, the temperature package needs to be re-adjusted, at the same time pay attention to cleaning inspection.

Second, the unit does not turn, no display failure analysis: It may be a power supply fault or blown fuse, thermal overload protector burned and the power cord is loose.

Diagnosis: First power off, then check the power switch, update the power cord, and check the unit.

Third, the compressor noise failure analysis: the fixed part of the pipe inside the loose vibration, thermal expansion is too large, the oil pressure is too low, or the muffler damage.

Diagnosis: Adjust the opening degree of the thermal expansion valve, check the piping of the compressor, and replace the lubricant and muffler.
