Hard Errors vs. Soft Errors

Hard Errors

Require a qualified technician to perform a reset on the internal control board.

Do not open the machine to access electrical controls. If a hard error occurs, disconnect power and request professional service.

Soft Errors

Machine shuts down for approximately 1 hour, then automatically retries.

If the underlying issue is resolved, a soft error clears on its own without intervention.

Additional Indicators — Maestro Plus & Horizon Elite

These indicators appear on Horizon Elite (710, 1010, 1410 series) and Maestro Plus (MCD425A/W) models.

HI PRESSURE

Clogged condenser on air-cooled models. Condenser coils need cleaning.

Hard Error — Requires manual reset

HI AMPS

Auger gearmotor drawing excessive current. Caused by jammed auger, scale buildup, or poor water quality.

Hard Error — Requires manual reset

DRAIN CLOG

Drain pan water backup detected. Check drain line for obstructions.

Check drain line and pan

20M / 2nd LED (Torque Error)

Machine runs briefly then shuts down. Indicates a torque overload on the auger motor.

Typically requires professional service

Red Maintenance Light: 6-Month Service Due

Timer-based indicator — not a fault or failure

What This Means

6-Month Timer Expired

Follett machines have a built-in 6-month countdown timer. When it reaches zero, the red Maintenance LED activates to signal that periodic cleaning and sanitization is due.

Manufacturer's Recommended Interval

Semi-annual cleaning aligns with the manufacturer's published maintenance schedule. Local water conditions may warrant more frequent attention; consult the Follett service manual.

Resolution Steps

1

Clean with SafeCLEAN

Use a manufacturer-approved cleaner (such as Follett SafeCLEAN) and follow the mix ratio and water temperature specified on the product label and in the Follett service manual. Never use bleach.

2

Sanitize with Nu-Calgon IMS-II

Use a manufacturer-approved sanitizer (such as Nu-Calgon IMS-II) at the dilution specified on the product label and in the Follett service manual.

3

Enter Maintenance Mode & Reset

Follow the reset procedure in the Follett service manual to clear the maintenance timer.

Contact qualified service if: You are unsure of the cleaning procedure or prefer to have a technician perform the maintenance.

Affected models: All Follett models — Symphony Plus, 7 Series, 15 Series, Horizon Elite, Maestro Plus

Yellow Low Water Light: Water Supply Issue

Machine cannot detect adequate water supply

Common Causes

Water Supply Valve Closed

The supply valve behind or under the machine may have been turned off during other maintenance.

Kinked or Blocked Water Line

Check the supply line for kinks, especially if the machine was recently moved.

Clogged Inlet Filter or Screen

Sediment in the supply water can deposit over time and clog the inlet filter.

Low Building Water Pressure

Insufficient supply pressure prevents the machine from filling properly.

Very Pure Water (Below 10 ppm TDS)

Follett machines require a minimum 10 ppm TDS for the conductivity sensor to detect water. Facilities using RO or DI water may trigger false Low Water errors.

Resolution Steps

1

Verify Water Supply

Confirm the supply valve is fully open and the water line is not kinked or pinched.

2

Inspect Inlet Screen

Visually inspect the inlet screen/filter for sediment. If sediment is visible, arrange cleaning or replacement per the Follett service manual.

3

Check Water Quality

If your facility uses RO or very soft water, test TDS levels. Water below 10 ppm TDS will cause false Low Water readings.

Contact qualified service if: Water supply checks out but the light persists — the water inlet valve or conductivity sensor may need replacement.

Affected models: All Follett models
T

Yellow Time Delay Light: Ice Jam or Timed Delay

Ice jam in transport tube or machine in timed delay cycle

What Triggers This Light

Ice Jam in Transport Tube

Ice has jammed in the transport mechanism between the evaporator and the storage bin. The machine pauses to let ice melt and clear.

Timed Delay Between Cycles

Normal operational pause between ice production cycles. The machine will resume automatically.

Resolution Steps

1

Wait for Automatic Clearing

In most cases, the machine resolves this on its own. Allow up to 30 minutes for the delay cycle to complete.

2

Check Bin Level

If the bin is overfull, dispense or remove some ice to allow the transport tube to clear.

Contact qualified service if: Time Delay light activates repeatedly — may indicate scale buildup in the transport tube or a failing auger motor.

Affected models: All Follett models with transport tube assemblies

HI PRESSURE & HI AMPS: Larger Model Errors

Hard errors on Horizon Elite and Maestro Plus — require manual reset

HI PRESSURE — Clogged Condenser

Air-Cooled Models Only

The condenser coils are clogged with dust, grease, or debris, causing refrigerant pressure to exceed safe limits.

Resolution

  • 1. Power off the machine
  • 2. Ensure adequate ventilation clearance around the unit
  • 3. Contact qualified service to clean the condenser, perform a control board reset, and clear the error (do not access internal controls yourself)

HI AMPS — Auger Motor Overload

Gearmotor Drawing Excessive Current

The auger motor is drawing excessive current. Common causes: jammed auger from scale buildup, foreign object, or worn bearings.

Resolution

  • 1. Power off the machine
  • 2. Note incoming water quality (mineral content accelerates scale)
  • 3. Contact qualified service to inspect the auger, descale the evaporator with a manufacturer-approved cleaner, clear the code, and perform control board diagnostics

Professional service recommended. HI AMPS errors often indicate significant scale buildup or mechanical wear that requires specialized tools.

Affected models: Horizon Elite (710, 1010, 1410), Maestro Plus (MCD425A/W)

Filter Replacement & Reset Procedure

Filter selection and reset procedure

Filter Selection

Filter cartridges vary by model. Consult the Follett service manual or a qualified service technician to identify the correct part number for your specific machine.

Filter Replacement Steps

1

Identify the Correct Filter

Identify the correct cartridge part number from the Follett service manual or a qualified service technician. Generic filters may compromise water quality.

2

Replace the Filter

Have the filter replaced per the Follett service manual, or by a qualified service technician. After replacement, flush the system per the manual before returning to service.

3

Request Filter Reset

Contact a qualified service technician to reset the filter timer on the internal control board. Do not open the machine or touch internal components yourself.

When to Replace Early

Filters may reach capacity before the timer expires depending on local water conditions and usage volume. If you notice reduced ice production or cloudy ice before the filter indicator activates, consult a qualified service technician about replacing the filter early.

Contact qualified service if the indicator will not reset after replacement.

Affected models: All Follett models
