Over the past 2 weeks we have had two calls to 2 seperate ice machines both of the dcm on the counter hoshizaki nugget machines.
Both units will make ice as normal for approx 20 or 25 mins
then will start to make a high pitch squealing noise.
which is definately coming from where the ice is forced through from the bottom.
OK spoke to factory about one of the machines my boss took care of the other.
Factory suggested cleaning machine to remove calcium build up, and or replacing the TXV they believe that the TXV could well be freezing the ice too much making it to hard hence the squealing noise.
Well my colleague went yesterday to change the TXV on the dcm 500 replaced it and the same noise would occur(high pitched squeal) so he cleaned the machine filling the drum with water and ice machine cleaner jumped the auger motor and allowed it to run hopefully cleaning it enough. Allowed to run for about half of an hour drained machine and fired it back up with the same high pitched squeal again occuring.
I havent been back to the other machine yet since we havent resolved this one yet, my boss seems to thinkits a possible floor with the ice machines.
Any ideas would be much appreciated anyone had the same problem.
