    refrigeration 101 where the frost line starts, is a restriction, yes you will need to change the drier. you said the water reg valve was leaking, i understand that to be the electric water solenoid valve, but if you recovered refrigerant, evacuated and recharge it sound like you changed the expandsion valve? Your current problem sounds like a plugged filter drier. But im concern what plugged the filter, how old of a unit is this, has it had any previous compressor failures etc.....

    First change the drier and start over. Also you have me confused. Says you were called out for water leaking into ice bin but you end up changing the cond. regulating valve?
    I understand that it was probably bad as they go bad very often but what about the original call.

    this unit has everything original but, bin control. unit has to be about 12 yrs old. water was leaking from the water
    regulating valve coming out the side and back and onto the floor. i replaced the drier. all is good. purrrring like a kitten. waited for 4 harvests perfect every time. what had me stumped was the old strainer had some frost on it and was working fine i guess with the evac and recharge it plugged up completely installed a 052 drier works great so far the strainer drier also was original thanks for the help

    Want to hear something funny. That's the first I've heard of a cond water valve leaking water on a hosh. That's why I was asking about the leak and didn't put 2 & 2 together.
    Let me add that I service somewhere around 120 hoshizaki km's and some flakers. I have seen just about everything go wrong that can go wrong with these units.

    Glad to hear everything is going fine.
