My manitowoc model qy0275w is constantly draining. why?

Check the dump valve. Pull the wiring harness off of it to see if water stops dumping, if it dose not stop dumping then replace the valve. If if stops dumping water then you need to see what is causing power to be sent to dump valve this valve should not open until it gets a call from the control board when it goes into a harvest.

First is the ice to thick coming off of the evaporator plate? If so then you need to adjust the ice thickness probe located at the top of the evaporator plate it is white with a 1/4" screw going through it, turn if left an 1/8" at a time let it make ice and check each batch. Now for chunky ice is it melted together? If so then make sure the machine is not dumping water into the bin during harvest if it is then check the dump valve to make sure it is opening during harvest cycle.

Water keeps running after harvest,water does not raise float on a sce170a why

If I remember, this model is equipped with a dump valve solenoid valve and is probably stuck open and needs to be replaced.

Hoshizaki km500mae just has continuous water flow through it. The only time it shuts off is when it is harvesting ice. This water is causing a huge water bill. Any suggestions?

You have an assembly that closes the water down when it is harvest ice. It is broke or out of adjustment. Have a rep look at it.

70267990 Water will not run into the icemaker

Pretty simple fix. Your ice maker is it's own boss. It calls for water to be added after each harvest cycle. It and it alone. You have 4 things that could be wrong. Bad ice maker, bad water valve, bad water filter, and dirty condenser coils. The ice maker has a thermostat in it that calls for harvest. When that thermostat closes it powers up the motor and heater. Since the heater requires the most shocktricity to operate the motor will barely move. However as the ice melts the motor will gain ground until the main drive wheel rotates past a certain point and the heater is disengaged from the circuit, then the motor travels on around and dumps the ice. Near the very end of the harvest cycle a lever is tripped that powers the water valve for 7.5 seconds and fills the mold. Logically you want to replace the cheapest component of the 2 (ice maker and water valve) first just to see if that fixes it. You need a new watervalve anyway if you install a new ice maker. If installing a water valve don't do it (after you have cleaned the coils and know the water filter is ok and you have paid the water bill) then you would replace the ice maker itself. If the ice mold is full of ice and won't harvest you have a bad ice maker. Good rule of thumb: If you can add some water to an empty ice mold and it kicks out a batch then you need a new water valve.

Unit makes ice,full evaporator,is very slow,maybe 45 mins. from harvest to harvest. Why so slow?

Possible causes are many
Things to check
  • If air cooled, is the condenser coil clean and is the condenser fan running when in ice production ? Is the area extremely hot where the ice machine is located? If water cooled, is there adequate water pressure and is the water regulating valve set properly?
  • When the system switch is in the off position is there any water running ( if so the inlet water valve may be stuck open)
  • When in ice production, is the small tube that feeds from the hot gas solenoid hot? This tube comes from a valve at the back of the unit and feeds over the compressor and into a tee near the insulated Tx valve. This line should be hot during harvest and cool shortly after harvest.
  • Has the float switch assembly been cleaned. this is a cylindrical unit beside the water pump,It can get plugged with minerals and not initiate harvest
  • The system may have a refrigerant charge problem (short) or the compressor may be weak, at which point diagnosis would need to be done by a refrigeration tech
Hope this helps

Scotsman icemachine cm506 stuck in harvest hot gas won't close any ideas?

check for power to valve coil. If it remains it's a control problem. If no power and still in harvest, valve is stuck. Unit usually does not exceed a 6 to 8 minute harvest.
