Needs attention soon

Can you clear it yourself?

Sometimes, after the safe checks below

Most likely cause

Ice output is slower than the water entering the reservoir

What you may notice with 11

• The display shows the plain number 11, with no E in front.
• Ice comes out slower than usual or stops for a while.
• The bin holds less ice than it normally does by now.
• The unit still has power and the display stays lit.

How the ice machine detects 11

A nugget ice maker keeps a small pool of water in a tray or reservoir and turns that water into ice as it runs. The control watches how high the water stands in that reservoir. Water is let in as ice is made, so the level normally rises and falls within a narrow range while the machine works.

When the level climbs above where it should be, the control shows 11. It reads a high level as a sign that ice is not being made quickly enough to use the incoming water, so the supply is outrunning production. The same display can also appear when the sensed level and the actual water in the reservoir do not match. Either way the machine slows its ice output while 11 is showing, and the code holds until the level comes back down to the normal range.

Likely causes of 11

• Ice output is slower than the water entering the reservoir
• The level reading is higher than the actual water in the reservoir
• A blocked bin opening is holding up ice production

Can you keep using the ice machine with 11?

The machine can stay plugged in, but it will not make ice at a normal rate while 11 shows. The code itself is no electrical or fire danger. Do not drain or tilt the reservoir to force the level down, since that leaves water where it should not be. Switch the unit off and have it checked if you see water outside the machine or if 11 comes straight back after a restart.

What you can safely check

1. Switch the ice maker off and unplug it; do not drain the reservoir or tilt the unit.
2. Make sure the cabinet sits level.
3. Look into the bin opening for ice chunks or debris in the way.
4. Follow the water supply line and straighten any kink.
5. Wait a few minutes, plug it in and switch it on.
6. When 11 stays on the display, contact us instead of draining the reservoir yourself.

What our technician does for 11

• Separate a supply-side cause from an ice-side cause
• Test the water level sensing against the real level
• Check the ice path for anything slowing production
• Repair or replace the part that tested bad

How to keep 11 from coming back

• Keep the unit level and the bin opening clear of ice buildup or loose debris.
• Check the supply line now and then for a kink or a pinch behind the cabinet.
• Ask us about a cleaning routine suited to your water if scale builds up in the machine.
