Why is my older Hoshizaki ice machine (unknown model) evaporator frozen solid including water tub below evaporator. Hopefully, cleaning will help but I don't see how cleaning would prevent tub water from freezing solid too.
If the defrost/hot cycle doesn't work, the ice won't fall and eventually freeze everything.
Testimonial: "Thanks, I should have indicated that this machine is water-cooled & problem does not develop until bin is full of ice; does your solution still apply?"
well, yes and no. there should be a limit switch or shield that stops ice production when the bin is full. otherwise the ice will pile up and eventually stop the new ice from dropping. if it stays on the coils when new water comes down, everything will freeze up. also, there should be an ice thickness probe near the top. when the ice gets thick enough to touch the probe, it goes into the drop cycle. if the probe is broken or bent way out, it'll keep running water and freezing. so, check those and let me know.

Bob,
You need to back down your bin switch a bit which is a thermostatic switch,
also, there is a microswitch on the white ( cleaning switch) with closes off the compressor while cleaning.
Now you must turn the switch ALL the way when cleaning to activate the microswitch which is behind the white know................OHM it out to see if it is working,
If it does not ohm out, then you need to change the micro switch or "cherry switch",
if the problem still develops, then you need to try to adjust your water valve ( you said it was water cooled), if it STILL is freezing up, then you need a new universal board = $189.99,
Good Luck,
Daniel
Might need to clean it

why does my hoshizaki model am-150BAF freeze up? I've changed the thermister and the control board. its like it doesnt cut off when its time to drop the ice it just keeps running until its all completely frozen.
