    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.
  • Page 20 1. Operation Diagnosis 3) Power On: Turn on the power supply, then move the control switch to the "ICE" position. A 5-sec. delay occurs. CB red "POWER OK" LED and green "BC CLOSED" LED turn on. If yellow "BC OPEN" LED is on (indicating a full bin), check BC. Move ice away from BC actuator paddle.
  • Page 21 5a) Initial Harvest Cycle – LEDs 1, 4, and 2 are on. WV and X11 relay continue. Comp, FM* (if connected to CB K1 connector pin #9), FMR, HGV, and X10 relay energize. CB monitors the warming of the evaporator via the thermistor located on the suction line.
  • Page 22 5b) Harvest Pump Time (Harvest Assist) – LEDs 1, 3, and 2 are on. 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). When WV de-energizes, LED 4 turns off, X11 relay de-energizes and LED 3 turns on.
  • Page 23 a) Freeze Cycle Diagnosis: Confirm Comp, FM* (if connected to CB K1 connector pin #9), FMR, and PM continue. Confirm that FM (if not connected to CB K1 connector pin #9) and LLV energize. Confirm WRV opens. Next, confirm HGV and X10 relay de-energize.
  • Page 24 f) Refrigerant Pressures, HM, and TXV Diagnosis: If evaporator is still not cooling, check refrigerant pressures. See "VIII.A. Specification and Performance Data." Next, check HM operation. If refrigeration pressures are above HM setpoint and HM is bypassing, replace HM. Check TXV for proper operation. Remove TXV bulb and hold it in your hand, refrigerant low-side pressure should rise, place TXV bulb in ice water, refrigerant low-side pressure should drop.
  • Page 25 pump-out is complete. The pump-out frequency control (S4 dip switch 5) is factory set, and generally no adjustment is required. However, the pump-out frequency control can be set to have a pump-out occur every 10 cycles or every cycle. For details, see "III.C.4. Pump-Out Frequency Control (S4 dip switch 5)."...

  • Page 26: Freeze-Time Correction Cycle (90 Min.)

    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 minimum and maximum freeze times have exceeded differential parameters. Freeze-time correction timer and count starts at the beginning of the 2nd freeze cycle after startup from power off condition.
  • Page 27 2) Freeze-Time Correction Sequence: First occurrence within 36 hr., minimum and maximum freeze times have exceeded differential parameters. CB "POWER OK" LED starts blinking. Freeze-Time Correction Cycle starts. Second occurrence within 36 hr., minimum and maximum freeze times have exceeded differential parameters.

  • Page 28: Control Board Check

    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.

  • Page 29: Bin Control Check

    E. Bin Control Check 1. Bin Control Check This appliance uses a lever-actuated proximity switch to control the ice level in the storage bin. No adjustment is required. To check BC, follow the steps below. 1) Turn off the power supply. 2) Remove the front panel, then move the control switch to the "OFF"...

  • Page 30: Bin Control Cleaning

    4) Disconnect BC connector from CB K4 connector, then remove BC from the icemaker. 5) Remove the actuator paddle from the switch mount. See Fig. 2. 6) Wipe down BC with a mixture of 1 part of Hoshizaki "Scale Away" and 25 parts of warm water. Rinse the parts thoroughly with clean water.

  • Page 31: Float Switch Check And Cleaning

    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.

  • Page 32: Float Switch Cleaning

    Be careful not to bend the retainer rod excessively when removing it. 7) Wipe down FS housing, shaft, float, and retainer rod with a mixture of 1 part Hoshizaki "Scale Away" and 25 parts warm water. Clean the inside of the rubber boot and hose with cleaning solution.

  • Page 33: Thermistor Check

    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. 3) Remove the control box cover. 4) Remove the thermistor from the refrigerant tubing. 5) Immerse the thermistor sensor portion in a glass containing ice and water for 2 or 3 min.

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.

  • Page 44: Pump-Out Frequency Control (S4 Dip Switch 5)

    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.
