| Error Code | Appliance | Meaning | Safe first steps | Technician required | Related help |
|---|---|---|---|---|---|
| rsF | Refrigerator | Refrigeration system failure; the temperature continues to climb while the compressor is on, so the control shuts the refrigeration system down until the unit is power-cycled. | Before power-cycling, verify door closure, hot-product loading, airflow obstruction, evaporator icing, condenser cleanliness, and fan operation. | Yes - if rsF returns, the guide says the unit has detected a mechanical refrigeration problem. | |
| CHt | Refrigerator | Dirty condenser alarm; condenser temperature is too high, and the control shuts refrigeration down until the coil is cleaned and the unit is power-cycled. | Clean the condenser coil thoroughly, verify condenser airflow / fan operation, then power-cycle the unit after cleaning. | Yes - if the coil is clean, airflow is correct, and CHt returns. | |
| HI | Freezer | Cabinet probe high temperature alarm (temperature over 113F / 45C). | Press START/STOP to start cooling, then recheck cabinet temperature after about 2 hours. Confirm the door is closed and inspect whether the cabinet probe or compressor may be at fault if the alarm remains. | Yes - if HI remains after the official restart and temperature recheck. | |
| E08 | Modular Ice Machines | Condenser temperature sensor short fault (no shutdown; error LED every 5 seconds). | Reseat the condenser-temperature probe leads at the controller and ohm-test the probe in 32F ice water against the published value. | Yes - if the probe circuit tests out of range or wiring damage is found. | |
| E12 | Modular Ice Machines | Water level control fault (protective shutdown). | Restart the machine and observe the 140-second countdown. After about 60 seconds, the water pump should start. If it does not, test / replace the water pump. | Yes - if the pump does not start as specified. | |
| E13 | Modular Ice Machines | Pump or water level fault (protective shutdown). | Restart the machine and verify: tank fills only to the sensor level, water pump starts after about 60 seconds, and the drain valve opens after harvest. | Yes - if any step in that sequence fails and component replacement / diagnosis is needed. |
