E0 = pump defective water
E1 = high pressure control worked or uncalibrated.
E2 = emersion sensor of the evaporator served or uncalibrated.
E3 = low pressure switch worked or uncalibrated.
E4 = the compressor discharge sensor served for high-temperature compressor discharge.
E5 = high current protector of the compressor served.
E6 = communication error between the plates of the evaporator and condenser.
E8 = motor protection evaporator served.
E9 = water pump protection served or is uncalibrated.
F0 = evaporator temperature sensor acted or is out of calibration.
F1 = evaporator immersion sensor acted or is out of calibration.
F2 = emergence of condenser sensor acted or is uncalibrated
F3 = condensing temperature sensor acted or is out of calibration.
F4 = discharge sensor malfunctioning compressor
F5 = ambient sensor defective diplay.
EH = resistance auxiliary heating failed.
FF = micro switch evaporator in wrong or open position.
C5 = jumper Faulty or no capacity on the main PCB.
C1 = protection against arc.
C2 = protection against dispersion of refrigerant.
CF = short-circuit protection
Here are a few checks on the errors below:
E1 = with flashing red LED - indicates that the OVC signal is not reaching the X20 mainboard connector check in condensing the high pressure switch, the relay current and thermal fuses in the connection terminal block. Some of these components is open or opening during operation generating the error.
E2 = with flashing red LED - indicates that the evaporator immersion sensor detected freezing or is out of calibration. To test the sensor using the table 20K sensor bulletin.
E3 = with flashing red LED - indicates that the LPP signal is not reaching the X-19 connector on the motherboard. Check in condensing the low pressure switch it will be open or opening during operation of equipment indicating lack of gas or that it is out of calibration.
E4 = indicates that the immersion sensor connected to the compressor discharge temperature detected high in the refrigerant gas outlet. Check the gas charge and possible obstructions or lack of ventilation in the condenser. The sensor and 50K.
E5 = indicates that there was a power failure for more than 3 seconds or the current reached up to 25 amperes. The plate off the compressor and presents E5 when this occurs 6 times.
red LED flashing indicates that the compressor discharge sensor is loose or uncalibrated. Check the bulletin in 1303 to test its resistance. After some time appear E3 error together.
Temperature sensor shows no error, but the evaporator is only fanning. Check if it is not in trouble by 15K sensor bulletin. The fact display error does not mean that the problem is on the board or in the open component. Lack of gas, dirty condenser, phase failure, bad capacitor, etc. generate these errors. always check the pressure, current, voltage, insufflation and other data before asking for guidance.
