Unit fills but the gearmotor does not start

130: Flaker Fill System The reservoir in a Hoshizaki auger type icemaker feeds water by gravity flow to the evaporator cylinder. The level of water in the reservoir is maintained by the operation of a dual float switch assembly To continue reading this article, click here. 138: Service Q&A Question: We occasionally receive a flaker series call and the technician claims the water reservoir is full, but the gear motor and compressor do not start.

Gear motor trips overload/fuse

159: Flaker Gear Motor Protection Recent investigation of our flaker gear motor overload protector has resulted in a change in the style of protection used. Previously, the gear motor reset has been a manual push button reset (current type) overload. It was found that this overload would not react quickly in a low voltage situation. Consequently, operating in a low voltage condition could result in unnecessary stress to the gear motor assembly To continue reading this article, click here.

How do I check Flaker bearings?

102: Bearning Inspection Bearings on a flaker are considered a wear item and should be inspected periodically for excessive wear. Inspection of the bearings on a Hoshizaki Flaker or DCM is a simple process, which can be completed in 15 minutes or less. The steps for bearing inspection are as follows To continue reading this article, click here. 117: Flaker Bearing Gauge Bearing Gap is the clearance, or "play", between the auger shaft surface and the sleeve-bearing surface. The maximum allowable gap for all Hoshizaki Flakers or DCM's is .02" (twenty thousandths inch) with the auger shaft pressed tight against one side of the bearing surface. If the clearance exceeds .02", both the upper and lower bearings should be replaced To continue reading this article, click here.

How do I remove the auger?

131: DCM Auger Removal The DCM (Dispenser Cubelet Maker) makes cubelet or (chunklet) ice, stores it, and dispenses water and ice as needed. The size of this cubelet is approximately 5/8" high x1/2" wide x 3/8" thick. You will find that a DCM has the same basic icemaker design as a Hoshizaki flaker along with additional dispensing and agitation components. There are however some subtle differences in the evaporator section, which allow the flaked ice to come out as cubelets To continue reading this article, click here.

What is Cubelet Ice?

118: Flaker Cubelet Conversions Hoshizaki America, Inc. now has available, from the factory, selected Flaker models that are being manufactured with cubelet conversions installed. The F-650 and F-1000 are available at this time and have a -C (dash C), at the end of the model number. These models produce ice that is similar to the DCM product To continue reading this article, click here. 139: DCM Ice DCM stands for Dispenser Cubelet Machine. The ice produced by this auger style unit has a unique shape and falls in the 90% hardness range. This harder cubelet dispenses easily and has less problems with bridging in the small, air tight DCM storage bin. A Hoshizaki flaker can be converted to produce the cubelet style ice, however the converted cubelet will fall in the 85% hardness range To continue reading this article, click here.
