here are some of the error codes that can be displayed on a Dometic marine air conditioner:

E1: Ambient room temperature error. This means that the air conditioner is not able to maintain the desired temperature in the room. This can be caused by a number of factors, such as a dirty air filter, a blocked air intake or exhaust, or a problem with the compressor.
E2: Evaporator sensor error. This means that the air conditioner is not able to accurately measure the temperature of the evaporator coil. This can be caused by a faulty sensor, a loose or damaged wire, or a problem with the control board.
E4: Display panel communication error. This means that the air conditioner is not able to communicate with the display panel. This can be caused by a loose or damaged wire, a faulty control board, or a problem with the display panel itself.
F4: Outdoor temperature sensor error. This means that the air conditioner is not able to accurately measure the temperature of the outdoor unit. This can be caused by a faulty sensor, a loose or damaged wire, or a problem with the control board.
F0: Refrigerant sensor error. This means that the air conditioner is not able to accurately measure the amount of refrigerant in the system. This can be caused by a low refrigerant level, a faulty sensor, a loose or damaged wire, or a problem with the control board.
CF: Filter error. This means that the air filter is dirty and needs to be cleaned.
LE: Low temperature error. This means that the air conditioner is not able to cool the room below a certain temperature. This can be caused by a number of factors, such as a dirty air filter, a blocked air intake or exhaust, or a problem with the compressor.
HE: High temperature error. This means that the air conditioner is not able to cool the room above a certain temperature. This can be caused by a number of factors, such as a dirty air filter, a blocked air intake or exhaust, or a problem with the compressor.
HL: Water tank full error. This means that the water tank in the air conditioner is full and needs to be emptied.
PF: Probe failure error. This means that one of the temperature sensors in the air conditioner has failed. This can be caused by a faulty sensor, a loose or damaged wire, or a problem with the control board.
HPF: High pressure fault error. This means that the pressure in the refrigerant system is too high. This can be caused by a number of factors, such as a low refrigerant level, a problem with the compressor, or a blockage in the system.
LPF: Low pressure fault error. This means that the pressure in the refrigerant system is too low. This can be caused by a number of factors, such as a high refrigerant level, a problem with the compressor, or a leak in the system.
