How do I maintain a Follett unit?

Follow the Follett recommended maintenance schedule: daily cleaning of accessible surfaces, weekly inspection of seals and gaskets, monthly check of electrical connections and water filters, and annual professional service including calibration and safety checks.

Where can I find Follett parts and documentation?

Genuine Follett replacement parts and service documentation are available through authorised dealers. For instant answers about Follett troubleshooting and maintenance, use AskWhiz on WhatsApp.

What does HI AMPS mean on a Follett Horizon icemaker?

HI AMPS means the PC board sees the auger gearmotor pulling current above its limit, 3.8 amps on a Horizon machine. A soft fault lights TIME DELAY, HI AMP and SERVICE, shuts the machine down, then self-clears after the time delay. A second HI AMP inside the six-hour countdown, or the drive relay energized with no current, becomes a hard error that locks the unit off. Common causes are auger or evaporator binding, a failing gearmotor, or an open drive circuit. Start by reading the LED combination to tell soft from hard, let a soft delay run, then inspect the auger for binding and measure gearmotor amperage. Because that means working on a live 208-230 V circuit near moving and hot parts, repeated or hard faults and any gearmotor replacement should go to a Follett-authorized technician.

What does LO WATER mean on a Follett Horizon icemaker?

LO WATER means the reservoir level sensors are not seeing enough water. A soft error trips if water does not reach the normal low sensor within 120 seconds while running; the machine stops but the feed solenoid stays energized, and it clears once water returns. A hard error occurs if there is no water at the bottom sensor within 60 seconds of power-up, or the sensors are disconnected or damaged. Causes include a shut-off or restricted supply, a clogged inlet, filter or feed solenoid, or water below 10 ppm dissolved solids that the conductivity sensors cannot read. First confirm the supply is on and at pressure, then check whether it is soft or hard, inspect the level rods, and verify conductivity. A hard fault at power-up or damaged sensors needs a Follett-authorized technician.

What does HI PRESSURE mean on a Follett Horizon icemaker?

HI PRESSURE is a refrigeration hard error: when high-side pressure rises above 425 psi, the HI PRESS red alarm LED lights and the machine shuts off. Because it is a hard error, it will not restart even after pressure drops back below the 295 psi reset point; you must clear it with the reset button. Typical causes are a dirty or blocked condenser, ambient air above the 100 F maximum or restricted grilles, a water-cooled condenser water-supply problem, or an overcharge or non-condensables in the system. Confirm the hard error, clean the condenser coil and clear the grilles, check that ambient is within 50 to 100 F, and verify water flow on water-cooled units before pressing reset. Charge and sealed-system work require an EPA-certified Follett-authorized technician. Do not defeat the lockout.

What does DRAIN CLOG mean on a Follett Horizon icemaker?

DRAIN CLOG means the drain clog sensor in the plastic drain pan has detected water rising near the top edge because it is not draining properly, and the board lights the red alarm LED. It often shows up during the self-flushing purge cycle when drainage cannot keep up. Causes include a blocked or restricted drain line, a drain not sloped to spec, scale or sediment in the pan or drain path, a drain solenoid that is not opening, or a fouled sensor. Confirm the alarm and look for standing water in the pan, clear the drain line, and verify the 3/4 inch vented line slopes at least 1/4 inch per foot and is not tied into other drains. Check the drain solenoid and clean the pan. If the alarm returns after the line is clear, have a Follett-authorized technician check the drain circuit.

What does WATER LEAK mean on a Follett 7 or 15 Series dispenser?

On 7 and 15 Series ice and water dispensers, the red Water leak LED means an internal leak has been detected inside the cabinet, listed among the red fault indicators in the LED Indicator Description. It signals water where it should not be, and because that water can reach electrical components it warrants prompt attention. Likely sources are a leaking internal water line, fitting or connection, a filter or inlet connection that is not fully seated, or a reservoir, valve or tubing leak; a faulty leak sensor can also report falsely. Before opening the cabinet, disconnect power and shut off the water, then follow the Accessing Internal Components procedure to inspect the lines, fittings, filter, reservoir and valves and repair the source. Tracing an internal leak combines water with electrical parts, so leave it to a Follett-authorized technician.

Quick Answer

Follett ice machines and dispensers report named board conditions, not numeric codes. Horizon icemakers light HI AMPS, LO WATER, DRAIN CLOG, HI PRESSURE, plus SERVICE, TIME DELAY and LOW BIN status LEDs. The 7 and 15 Series ice/water dispensers add DRIP TRAY, WATER LEAK, PM and SLEEP CYCLE. Each is shown as a labeled LED, and many distinguish soft (self-clearing) from hard (reset-button) faults.

What error codes does Follett display?

HI AMPS

Auger gearmotor current exceeded the limit. Check for auger binding and verify gearmotor amperage.

LO WATER

Insufficient or no water at the reservoir sensors. Confirm supply and inspect the level sensors.

DRAIN CLOG

Water rose in the drain pan. Clear the drain line and confirm proper slope and a working drain solenoid.

HI PRESSURE

Refrigeration high-pressure hard error over 425 psi. Clean the condenser, check ambient, then reset.

SERVICE

Service needed: pairs with HI AMP on Horizon, or signals the 8000-hour bushing check on 7/15 Series.

TIME DELAY

Normal restart delay after a full bin or soft amps time-out. Wait for the delay to expire.

LOW BIN

Bin switch closed, calling for ice. If off with an empty bin, check the shuttle and transport tube.

DRIP TRAY

Drip tray full on 7/15 Series. Empty the tray and check the optional drain kit.

WATER LEAK

Internal dispenser leak on 7/15 Series. Cut power and water, then find and repair the source.

Six-month periodic maintenance due on 7/15 Series. Clean, sanitize, then cycle Maintenance Mode to reset.
