Elmeco Slush Machine Error Code ALARM LEVEL: Level Probe
ALARM LEVEL on an Elmeco First Class slush machine shows when the level probe is missing or not making proper contact. The manual says to disconnect the power cable, then check the level probe and its terminal board connection. A probe that is out of place is the simplest thing to find.
Medium: a missing probe stops normal control, but it is often a simple fix.

What does Elmeco ALARM LEVEL mean?
The First Class board uses a level probe in the product bowl to know there is liquid present. The probe and the cover contact also tell the board that the machine is assembled the way it should be. If the board cannot see a proper probe signal, it raises an alarm. The board blinks, and pressing the MENU button for one second shows ALARM LEVEL. The manual says the level alarm shows when the level probe is missing or not making proper contact. It gives two causes: the level probe is missing, or the cover contact, level probe or terminal board is not correct. The action is to disconnect the power cable first, then check the level probe and its connection at the terminal board. Nothing else is listed. Because the cover contact is part of the cause list, putting the cover back correctly after cleaning matters as much as the probe itself.
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.
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 LEVEL shows after pressing MENU
- The machine stops or will not start after cleaning
- Cover or probe looks out of place
Possible causes
Listed in Elmeco's documentation
- Level probe missing
- Cover contact, level probe or terminal board not correct
Other likely causes — what usually sits behind ALARM LEVEL on this control. A technician confirms which one it is before any part is replaced.
- Probe left out or loosened when the bowl was cleaned
- Cover not seated, so its contact does not close
- Terminal board connector corroded by syrup or moisture
- Probe wire pinched when the cover was refitted
Safe checks before calling for service
- Disconnect the power cable first, as the manual says.
- Check that the level probe is present and sitting in its place in the bowl.
- Close the cover fully so the cover contact is made, then reconnect power and press MENU for one second.
- Tell the technician whether the alarm began just after cleaning or refilling.
How a technician diagnoses ALARM LEVEL
- Confirm ALARM LEVEL from the MENU button.
- With power disconnected, check the level probe is present and seated.
- Inspect the cover contact for alignment and wear.
- Check the probe connection at the terminal board for looseness and oxide.
- Test continuity of the probe wiring.
- Reconnect and confirm the alarm clears on a full cycle.
- The terminal board is on the mains side of the machine, so reaching it means working near live parts.
- Wiring continuity and contact oxide need a meter and careful cleaning.
- A cover contact that is worn needs the right replacement, not a bent workaround.
How ALARM LEVEL differs from similar codes
ALARM LEVEL is about a missing or poor probe contact. ALARM REFILL is the autofill alarm, where the probe sees no liquid for over 2 minutes.

Can I run the machine with ALARM LEVEL?
We advise against it. The board cannot see a proper probe signal, so protection depends on the probe being in place.
Did I cause it by cleaning?
Possibly. The manual lists a missing probe and a wrong cover contact, both easy to disturb during cleaning.
Will it clear itself?
Once the probe and cover are correct, it should stop. If not, the terminal board needs a technician.
