Follett Horizon Elite Error Codes — What They Mean
Follett Horizon Elite ice and water dispensers (7HCD, 15HCD, 25HCD, 50HCD, and 110HCD series) are among the most common ice dispensing machines in healthcare facilities, hotels, and food service. Their electronic controllers display alphanumeric error codes when faults are detected. This guide covers the most common Horizon Elite error codes.
Common Error Codes
| Code | Meaning |
|---|---|
| E1 | Ice Making Fault (general ice production fault) |
| E2 | Water Inlet Fault |
| E3 | Ice Level Sensor Fault |
| E4 | Auger Motor Fault |
| E5 | Refrigeration System Fault |
| Ht | High Temperature Alarm |
Common Causes
- E1 (ice making fault) — Low refrigerant, dirty condenser, or high water temperature preventing normal ice production cycle from completing.
- E2 (water inlet fault) — Low water pressure, clogged inlet valve screen, or failed water inlet solenoid.
- E3 (ice level sensor) — Failed or ice-bridged ice level sensor in the storage bin.
- E4 (auger motor) — Auger jammed with ice or auger motor has failed.
- E5 (refrigeration) — High pressure cutout, low charge, or compressor fault.
- Ht (high temp) — The storage bin temperature exceeded safe limits — door open, refrigeration failure, or high ambient.
Step-by-Step Fix
- For E1 — Run a cleaning cycle with Follett cleaner. Check condenser fins and fan. Verify water temperature is below 90°F.
- For E2 — Check water supply shutoff is fully open. Verify supply pressure (20–80 PSI). Remove and clean the inlet valve screen. Test solenoid coil resistance.
- For E3 — Inspect the ice level sensor in the bin for ice bridging (ice spanning over the sensor). Break up any bridge. Clean sensor with warm water. Test sensor function per the service manual.
- For E4 — Power off. Open the bin and check for ice jams around the auger. Clear any jam. Check auger motor resistance — open circuit = failed motor.
- For E5 / Ht — Check condenser cleanliness, ambient temperature, and door seal. Ht that persists after correcting environmental factors needs refrigeration system diagnosis.
Parts Often Needed
| Part | Notes |
|---|---|
| Auger motor | Common failure on higher-volume units |
| Ice level sensor | Replace if bridging is chronic or sensor fails |
| Water inlet valve | Replace if screen damage or coil failure |
| Follett Ice Machine Cleaner | Use quarterly |

Before ordering, match the ice-machine part to the model number, electrical rating, and failure symptom. Check current prices on Amazon - prices and availability change frequently.
When to Call a Pro
E5 refrigerant system faults require EPA 608 certification. Auger motor replacement on large Follett units (50HCD and above) requires a trained Follett service technician.
