Elmeco Slush Machine Error Code ALARM REFILL: Autofill Alarm
ALARM REFILL on an Elmeco First Class slush machine is an autofill alarm: the level probe has not sensed liquid in the tank. It appears only if the AUTOFILL screen is ON. The manual says to reset it by switching the board off and on with its button.
Medium: the tank is not being refilled, but the manual gives a simple reset.

What does Elmeco ALARM REFILL mean?
When AUTOFILL is turned on, the board expects to keep the tank topped up. It watches the level probe, and if the probe reads no liquid for longer than 2 minutes, the board shows ALARM REFILL after the board blinks and MENU is pressed for one second. The manual describes this as an autofill alarm and says it appears only when the AUTOFILL screen is ON, so a machine on manual fill will never show it. The listed cause is that the probe does not read liquid for longer than 2 minutes. The actions say to disconnect the power cable first, then reset by switching the electronic board off and on with its button, so that the level control restarts. The manual does not say why the tank was empty: the supply may have run out, a valve may not have opened, or the probe may be dirty. It only tells you how to restart the level control.
Affected models and control systems
This applies to Fetco by Elmeco First Class machines FC1, FC2 and FC3 with the Millennium electronic board, per manual 344PEL0101. It shows only when the AUTOFILL screen is ON.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- The board blinks and ALARM REFILL shows after pressing MENU
- The tank is low and not being refilled
- Autofill supply bag or line is empty
Possible causes
Listed in Elmeco's documentation
- Level probe does not read liquid in the tank for longer than 2 minutes
Other likely causes — what usually sits behind ALARM REFILL on this control. A technician confirms which one it is before any part is replaced.
- Mix supply container empty or the feed line pinched
- Autofill valve or pump not delivering
- Level probe coated with dried mix so it cannot sense liquid
- Autofill wiring loose at the board
Safe checks before calling for service
- Disconnect the power cable first, as the manual says.
- Check the supply container is not empty and the feed line is not kinked.
- Reconnect power, then switch the electronic board off and on with its button so the level control restarts.
- If the alarm returns, write down how long it took and whether liquid was visibly entering the tank.
How a technician diagnoses ALARM REFILL
- Confirm ALARM REFILL and that AUTOFILL is ON in the settings.
- Verify the supply and the feed line.
- Watch whether the autofill valve or pump operates when the level is low.
- Clean the level probe and check its connection at the terminal board.
- Check the board's autofill output and wiring.
- Restart the level control and observe a refill to confirm.
- The autofill valve and board outputs are on mains voltage.
- Separating a supply problem from a probe or valve problem takes timed observation and a meter.
- Mix residue inside lines needs a proper cleaning procedure.
How ALARM REFILL differs from similar codes
Unlike ALARM LEVEL, which means a missing or poorly contacting probe, this alarm only appears with AUTOFILL ON and comes from a probe that senses no liquid for over 2 minutes.

Can I turn AUTOFILL off to stop the alarm?
The manual says the alarm appears only if AUTOFILL is ON, but turning it off removes the automatic top-up, so someone must fill by hand.
Does switching the board off and on fix it?
The manual lists it as the reset. It restarts the level control, but if the tank is still empty the alarm will return.
Is a dirty probe possible?
Likely, since a coated probe cannot sense liquid. The manual does not state it, so it is something a technician checks.
