Fault: Phase reverse protection (no such protection)
Phenomenon: A fault code starts to appear within a few seconds after power is turned on, and the unit cannot be started
Cause:, enter The power supply is out of phase, the incoming power supply is not connected properly or the main line is out of phase, and the incoming power supply phase sequence is reversed
Check: Check whether the incoming power cord is well connected or the main line is in phase. Check the incoming power phase sequence
Treatment: Connect the incoming power cord or wait until the power supply is normal, change the power phase sequence
Fault: Outlet water temperature is too high protection (°C)
Phenomenon: A fault code appears just after the unit is started or after a period of time
br/>Cause: The amount of circulating water is not enough. The circulation pipe is blocked. There is air or no water in the circulation pipe
. The inlet water pressure is not enough (direct heating machine)
Check:, check the circulation volume of the circulating water pump,. Check the circulation Pipe, check the cold water inlet pressure
Treatment: Replace the circulating water pump with a large flow rate, clean the circulating pipe, remove air or add water to the water tank, and pressurize the incoming water
Fault: High-pressure switch protection (system pressure is too high High.)
Phenomenon: The press reports a fault and shuts down after starting for a few seconds or a period of time. After adding refrigerant to the system, the system fails to start and run
. At first, the system runs normally and the heating is good. It appears after a period of use that the heating capacity is significantly reduced, there is frost at the throttling part, and the high pressure is high and the low pressure is low. At this time, the compressor makes a dull sound until it fails and shuts down
Cause: The high-voltage switch circuit is open ., the high-pressure switch is broken, there is air or no water in the circulation pipe, the inlet water pressure is not enough (direct heating machine), the water temperature is too high, there is no water in the circulation pipe, the water flow is not enough, whether there is scale on the inner wall of the heat exchanger
, the amount of refrigerant added is too high Many times, the throttle valve (capillary tube, electronic expansion valve, thermal expansion valve) is blocked by debris in the system. The system contains excess moisture, causing the water to freeze at the throttle valve. Blocking the capillary tube is called ice blockage
Inspection:, check the high-voltage switch circuit, measure the high-pressure switch, check the circulation pipeline, check the cold water inlet pressure, check whether the water tank probe is installed in place, use a multimeter to measure the resistance of the water tank probe, check pipes, valves and heat exchangers
, check the system pressure and current, and check whether there is frost at the throttle valve when the machine is turned on. After shutting down, use a hot towel to wrap the entrance of the throttle valve into the evaporator several times. After the ice blockage melts, you can hear the pipe. There is a smooth sound of refrigerant flowing
After starting the compressor, frost begins to form again, resulting in the above situation, which can be used to determine that the capillary is blocked by ice
Treatment: Connect the high-voltage switch wire, and replace the high-pressure switch. Eliminate the air or add water to the water tank, pressurize the incoming water, install the water tank probe in place, replace the water tank probe, open the valve wide to remove foreign matter in the pipes and use a scale cleaning agent
Clean the heat exchanger, drain away excess refrigerant or press The nameplate requires quantitative addition of refrigerant, draining the system refrigerant and replacing the throttle valve, draining the system refrigerant and drying it, then vacuuming and adding refrigerant to the air energy heat pump water heater maintenance and disassembly service concept
