Common Hoshizaki Ice Machine Error Codes

Here are the most common Hoshizaki error codes and what they mean:

E1 - High Temperature Thermistor Fault

If your machine displays an E1 error, it means the high-temperature thermistor has detected temperatures above the normal operating range. This could be caused by a blocked condenser, a malfunctioning fan motor, or issues with the refrigerant system.

E2 - Bin Control Thermistor Fault

An E2 error indicates a problem with the bin control thermistor. The bin might be full, or there could be a malfunction in the bin control sensor that detects the ice level.

E3 - Long Freeze Cycle

When you see an E3 error, it suggests the freeze cycle is taking too long. Potential causes include low refrigerant levels, a dirty evaporator, or problems with the water supply or pump.

E4 - Long Harvest Cycle

An E4 error means the harvest cycle is taking too long. This could be due to issues with the hot gas valve, a clogged water supply, or a problem with the ice thickness control sensor.

E5 - High Voltage

An E5 error indicates that the voltage supplied to your ice machine is too high. This could stem from issues with the power supply or electrical wiring.

E6 - Low Voltage

Conversely, an E6 error suggests the voltage is too low. This might also be due to power supply problems or faulty electrical wiring.

E7 - High-Side Pressure Switch Open

If you encounter an E7 error, it means the high-side pressure switch has opened. This could be because of high refrigerant pressure, a blocked condenser, or a malfunctioning fan motor.

E8 - Low-Side Pressure Switch Open

An E8 error indicates that the low-side pressure switch has opened, which could be due to low refrigerant levels, a refrigerant leak, or compressor issues.

E9 - Compressor Overload

An E9 error suggests the compressor is experiencing an overload condition. This could be due to electrical issues, a faulty compressor, or problems with the refrigerant system.

EA - EEPROM Communication Error

Lastly, an EA error points to a communication problem with the EEPROM. This could indicate a fault in the control board or wiring issues.
