3 yr. old Hoshizaki km630 mah, Had a hard freeze(24 degrees) at the shop and checked the ice maker that sits outside main bldg. Main water supply line inside that joins the copper pipe to the plastic fittings broke loose. After refitting the threaded plastic fitting to copper pipe and no apparant leaks. Now with the power on and water supply on, getting one beep every 3 to 5 seconds. Wash cycle works and plenty of water thru the lines,but when switched to ice and start getting the one beep every few seconds?

Or a bad thermostat

it should be under warranty . is the water shut off to fridge . ice maker could be bad . make sure water to the ice maker is on just check your water line . a very easy common mistake and very easy fix if the water is not turned on to the ice maker it wont make ice . hope this helps let me know how it gos

A few simple things to check is the condenser for dust. Blow it out. If their is a water filter going into the unit change it. Get some ice machine cleaner and follow directions. Do these things before calling anyone out.

cycle is, fill cycle for 1 minute first. If there is not water entering the unit when first turned on, look for that issue. Water turned off, water valve not working or some restriction, clogged water filters, etc. That is got to happen first. Don't over look the bin stat being bad. Nothing happens if teh bin stat is bad. It sends voltage to the control board that runs the unit.

What is your question about the switch? not very clear as to what you are asking.

The main problem with Hoshizaki machines is if you are in a hard water area, if so do you have a good quality water filter, it may need changing. A quick way to check for calcium ot lime deposits in the machine is
1. Turn it off, run you clean hand around the area near the evaporator, are there any rough or flaky deposits there, if so you may need a chemical descale, contact a reputable fridge guy to do this for you.
2. The swinging arm motor may be faulty or possibly the ice sensor which controls the harvest cycle. If this is faulty sometimes the tray goes back up before the ice has slid off.
3. If the machine is situated in a cellar or other cool (less than 10 deg C / 50 deg f) this can sometimes affect the harvest cycle again to set this you need a tradesman.
4. Does the water flow properly over the lower part of the mould plate during a harvest cycle, the pipe can become blocked or dislodged.

Hope this is helpful

there could be a blockage of frozen water in the fill tube of the ice maker.
if there is no blockage then the nex thig to check is the main water valve that supplies the water to the ice maker.
you can check the power from the main pcb board to the ice maker and make sure you have current to the ice maker
if all else fails replace the ice maker
i hope this has helped in some way good luck

ck condensor fan motor that cools compressor under unit. yoder loop runs through center divider and causes gaskets to get hot

The way I understand how Hoshizaki machines work, the model number is usually what the unit will produce, in pounds of ice. Their manual states: "Approximate production/ 24 hours @ 70 degrees air/ 50 degrees water (incoming)" So, yours should be producing 450 pounds a day, approimately. Since I can not pin point your exact model, I found one that is close. It states: "Ice Production per cycle: 6.6 pounds, 360 pcs." Again, it is not you exact machine. Their web site does not show this model either. So this is the best info I can get for you. Hope this helps.
