if there was moisture in the system the condenser psi would be higher than normal not lower. i would say that your expansion valve and compressor are not working properly but probably neither is faulty. your expansion valve and compressor are operated by sensors (pressure and temp) and correspond to the type of evaporator and refrigerant used. if you are using a pressure sensor designed to work on an orfice tube evaporator but using it with an expansion valve evaporator that could be your first mistake. the pressure in the system is directly related to the temperature of the refrigerant when its at a vapor and liquid.
