B. Service Diagnosis WARNING • The appliance should be diagnosed and repaired only by qualified service personnel to reduce the risk of death, electric shock, serious injury, or fire. • Risk of electric shock. Control switch in "OFF" position does not de‑energize all loads Use extreme caution and exercise safe electrical practices. • Moving parts (e.g., fan blade) can crush and cut. Keep hands clear.
1. Sequence and Component Diagnosis 3) Power On: Turn on the power supply, then move the control switch to the "ON" position and the mode switch to the "ICE" position. A 5‑sec. delay occurs. CB red "POWER OK" LED turns on. If CB yellow "BC OPEN" LED is on (indicating a full bin), move ice away from BC sensing area. Note: • CB red "POWER OK" LED remains on unless the 10.5VAC power supply is interrupted (K2 connector). • Check CB using the steps in "II.D. Control Board Check" or BC using steps in "II.E.
5a) Initial Harvest Cycle – LEDs 1, 4, and 2 are on. WV continues. Comp, FMR, and HGV energize. CB monitors the warming of the evaporator via the thermistor located on the suction line. When the thermistor reaches 48°F (9°C), CB reads 3.9 kΩ from the thermistor and turns harvest termination over to the harvest timer (S4 dip switch 1 & 2 and S5 dip switch 4). WV are energized during harvest for a maximum of 6 min. or the length of harvest minus HPT setting (S4 dip switch 6), whichever is shorter.
5c) Initial Harvest Cycle Termination Diagnosis: When the thermistor reaches 48°F (9°C), CB reads 3.9 kΩ from the thermistor and turns harvest termination over to the harvest timer (S4 dip switch 1 & 2 and S5 dip switch 4). Check discharge line temperature. For a thermistor check, see "II.G. Thermistor Check." If 1-min. fill cycle starts after harvest timer terminates, check that FS is clean and operating properly, see "II.F. Float Switch Check and Cleaning." If FS is closed, CB proceeds to the next cycle.
d) PM Diagnosis: Confirm water is flowing over evaporator from PM and not WV. If PM de-energizes once freeze begins, check for 115VAC at CB K1 #4 (R) to neutral (W). If 115VAC is not present, replace CB. If 115VAC is present and PM is de-energized, check PM capacitor and motor winding continuity. e) FM and LLV Diagnosis: If FM or LLV does not energize, check for 115VAC at CB K1 #3 (BK) to neutral (W). If 115VAC is not present and LED 2 is on, check for 115VAC at CB K1 #1 (V).
7) Pump-Out Cycle – LEDs 1, 3, and 5 are on (10/20 second pump-out). Timing of the first pump-out is determined by S4 dip switch 5. See the table below. Control Board Settings S4 Dip Switch Setting Pump-Out Frequency Control Board OFF Every 10 cycles After 11th freeze cycle ON Every cycle After 2nd freeze cycle No. 5 Comp and FMR continue, HGV energizes. Note: If S4 dip switch 3 & 4 are set to 3 off and 4 on, LED 4 turns on and WV energizes. NOTICE! S5 dip switch 1 must not be adjusted.
C. Freeze-Time Correction Cycle (90 min.) Freeze-Time Correction function is enabled when S4 Dip Switch 7 is in the "ON" position and initiates when the difference between the minimum and maximum recorded freeze times is equal to or greater than 600 sec. (10 min. ). Freeze time is recorded and freeze cycles are counted starting at the 2nd freeze cycle after startup from a power off condition.
2a) 10-Min. Harvest Pump Time (Harvest Assist) with WV: CB "POWER OK" LED blinking. CB LEDs 1, 4, and 3 are on and Comp, FMR, HGV, PM, and WV energize. 10-min. timer starts. Once 10‑min. timer terminates, CB LEDs 1, 3, and 2 turn off and Comp, FMR, HGV, and PM de-energize. WV continues. 2b) 10-Min. Fill: CB LED 4 on and WV energized. 10-min. timer starts. 2c) Final 10-Min. Harvest Pump Time (Harvest Assist) with WV: CB "POWER OK" LED blinking. Once 10‑min.
D. Control Board Check Before replacing CB that does not show a visible defect and that you suspect is bad, always conduct the following check procedure. This procedure will help you verify your diagnosis. Alarm Reset: If CB is in alarm (beeping), press the "ALARM RESET" button on CB while CB is beeping. WARNING! Risk of electric shock. Care should be taken not to touch live terminals. Once reset, the icemaker starts at the 1-minute fill cycle. For audible alarm information, see "III.B.
E. Bin Control Check and Adjustment WARNING • All parts are factory-adjusted. Improper adjustments may adversely affect safety, performance, component life, and warranty coverage. • In Hoshizaki DB and DM dispenser applications, the bin control controller setting must be adjusted to 2. For Coca-Cola Freestyle® Dispenser and other dispenser applications, the bin control controller setting must be adjusted to 3.
4) As water begins to fill the water tank (1-min. fill), place an object 5" to 7" (127 to 178 mm) away from the bin control lens. See Fig. 3. 15 sec. later, the icemaker shuts down. Remove the object from the bin control lens. 30 sec. later, the icemaker restarts. Bin Control Lens Fig. 3 Cycle at Bin Shutdown Control Activation Fill Cycle 15 sec. after activation. Harvest Cycle If engaged 15 sec. or longer, at the end of harvest cycle. Freeze Cycle 15 sec.
2. Bin Control Adjustment WARNING • All parts are factory-adjusted. Improper adjustments may adversely affect safety, performance, component life, and warranty coverage. • In Hoshizaki DB and DM dispenser applications, the bin control controller setting must be adjusted to 2. For Coca-Cola Freestyle® Dispenser and non-Hoshizaki dispenser applications, the bin control controller setting must be adjusted to 3.
F. Float Switch Check and Cleaning FS is used to determine that there is sufficient water in the water tank after the 1‑min. fill cycle and after each harvest cycle. FS is also used to determine that the appropriate volume of water has been converted into ice before switching out of the freeze cycle. No adjustment is required. 1. Float Switch Check To check FS, follow the steps below. 1) Turn off the power supply. 2) Remove the front panel, then move the control switch to the "OFF" position.
2. Float Switch Cleaning Depending on local water conditions, scale may build up on FS. Scale on the switch can cause the float to stick. In this case, FS should be cleaned. 1) Turn off the power supply. 2) Remove the front panel, then move the control switch to the "OFF" position. 3) Remove the base cover, disconnect the water tank end of the pump tubing to drain the water tank. See Fig. 5. After the water tank has drained, reconnect the pump tubing.
G. Thermistor Check To check thermistor resistance, follow the steps below. 1) Turn off the power supply. 2) Remove the front panel. Move the control switch to the "OFF" position, then remove the top and right side panels. 3) Remove the thermistor from the refrigerant tubing. 4) Immerse the thermistor sensor portion in a glass containing ice and water for 2 or 3 min. 5) Disconnect the thermistor connector from CB K3 connector and check the resistance between thermistor leads. Normal range is 4.7 to 6.2 kΩ.

C. Settings and Adjustments NOTICE Dip switches are factory set. Failure to maintain factory settings may adversely affect performance and warranty coverage. For more information, contact your Hoshizaki Service Center. 1. Default Dip Switch Settings The dip switches are factory-adjusted to the following positions: S4 Dip Switch No.
2. Harvest Time (S4 dip switch 1 & 2) The harvest timer starts counting when the thermistor reaches 48°F (9°C) at the evaporator outlet and the control board reads 3.9 kΩ from the thermistor. The harvest timer is factory set, and generally no adjustment is required. However, a setting longer than the factory setting may be advised in cases where the drain provided at harvest needs to be prolonged for extra cleaning.
4. Pump-Out Frequency Control (S4 dip switch 5) The pump-out frequency control is factory set to drain the water tank every 10 cycles. Generally no adjustment is required. However, where water quality is bad and the icemaker needs a pump-out more often, the pump‑out frequency can be adjusted. The pump-out frequency control can be set to have a pump‑out occur every cycle, or every 10 cycles. The first pump-out is dependent on S4 dip switch 5. See the table below.
6. Harvest Pump Time (Harvest Assist)/Freeze-Time Correction (S4 dip switch 7) NOTICE Factory set for proper operation. Do not adjust. Adjustment outside of the factory default setting may result in damage to the appliance. a) Harvest Pump Time (Harvest Assist) Depending on S4 dip switch 7 setting, the pump motor either stays off or is energized during the last seconds of the harvest cycle. When the pump motor is energized (S4 dip switch 7 on), water circulates over the evaporator.
8. Freeze Timer (S4 dip switch 9 & 10) NOTICE Adjust to proper specification, or the icemaker may not operate correctly. The freeze timer setting determines the maximum allowed freeze time to prevent possible freeze-up issues. Upon termination of the freeze timer, the control board initiates the harvest cycle or pump-out cycle. After 2 consecutive freeze timer terminations, the control board shuts down the icemaker. In this case, see "II.J.3. Low Ice Production" for possible solutions.
10. Refill Counter (S5 dip switch 2 and 3) NOTICE Do not adjust. These must be left in the factory default position or the icemaker will not operate correctly.

Do not adjust. Adjustment outside the factory default setting may result in damage to the appliance. S5 Dip Switch Setting No.
IV. Refrigeration Circuit and Component Service Information WARNING • This appliance should be diagnosed and repaired only by qualified service personnel to reduce the risk of death, electric shock, serious injury, or fire. • Move the control switch to the "OFF" position and turn off the power supply. Place the disconnect in the "OFF" position. Lockout/Tagout to prevent the power supply from being turned back on inadvertently.
2. Brazing WARNING • R-404A itself is not flammable at atmospheric pressure and temperatures up to 176°F (80°C). • R-404A itself is not explosive or poisonous. However, when exposed to high temperatures (open flames), R-404A can be decomposed to form hydrofluoric acid and carbonyl fluoride both of which are hazardous. • Do not use silver alloy or copper alloy containing arsenic. 1) Braze all fittings while purging with nitrogen gas flowing at a pressure of 3 to 4 PSIG.
5) Disconnect the gauge manifold hose from the vacuum pump and attach it to a refrigerant service cylinder. Remember to loosen the connection and purge the air from the hose. For the required refrigerant charge, see the rating label inside the icemaker. Hoshizaki recommends only virgin refrigerant or reclaimed refrigerant which meets ARI Standard 700 (latest edition) be used. 6) A liquid charge is required when charging an R-404A system (to prevent fractionation).
B. Component Service Information NOTICE When replacing a component listed below, see the notes to help ensure proper operation. Component Compressor Notes 1 phase: Install a new start capacitor, run capacitor, and start relay. Thermostatic • Attach the thermostatic expansion valve bulb to the suction line in the same location as Expansion Valves the previous bulb. • The bulb should be between the 10 and 2 o'clock positions on the tube. • Secure the bulb with the clamp and holder, then insulate it.
C. Water Regulating Valve Adjustment (water-cooled model) The water regulating valve is factory set, and generally no adjustment is required. However, when necessary, adjust the water regulator using the following procedure. 1) Prepare a thermometer to check the condenser drain temperature. Attach a pressure gauge to the high-side line of the system. 2) 5 min. after a freeze cycle starts, confirm that the thermometer reads 104°F to 115°F (40°C to 46°C).
V. Maintenance The maintenance schedule below is a guideline. More frequent maintenance may be required depending on water quality, the appliance's environment, and local sanitation regulations WARNING • Only qualified service technicians should service the appliance. • To reduce the risk of electric shock, do not touch the control switch or service switch with damp hands • Before servicing: Move the control switch to the "OFF" position and turn off the power supply.
VI. Preparing the Appliance for Periods of Non-Use NOTICE • When storing the appliance for an extended time or in sub-freezing temperatures, follow the instructions below to prevent damage. • To prevent damage to the water pump, do not operate the appliance with the control switch in the "WASH" position when the water tank is empty. When the appliance is not used for two or three days under normal conditions, it is sufficient to move the control switch to the "OFF" position.
3. On water-cooled model, remove the water from the water-cooled condenser: 1) Make sure the power supply is off, then remove the front panel and right side panel. 2) Close the condenser water supply line shut-off valve.
