An ice maker that stops working can be frustrating, especially when you rely on it for daily use. If your AEG freezer’s ice maker is producing no ice, small cubes, or jamming, you can often fix the problem yourself without calling a technician. This guide covers the most common AEG freezer ice maker problems and provides step-by-step DIY fixes. We focus on models sold in Spain, such as the AEG SKS68840F0 and AEG SCE81826TS, but the advice applies to many similar units.

Before starting any repair, always unplug the freezer or switch off the circuit breaker. If you need a broader overview of AEG appliance repairs in Spain, see our Complete Guide to AEG Appliance Repair in Spain.

1. Ice Maker Not Producing Ice

The most common complaint is that the ice maker has stopped making ice entirely. This can have several causes.

Check the Water Supply

Most AEG freezers with an ice maker require a water line connection. If the water supply is off or the line is kinked, no water reaches the ice maker.

  • Ensure the water shut-off valve behind the freezer is fully open.
  • Inspect the copper or plastic tubing for kinks or sharp bends.
  • If the line is frozen, thaw it by turning off the freezer for a few hours or using a hair dryer on low heat (keep it moving to avoid damage).

Check the Water Inlet Valve

The water inlet valve (part number AEG 902979-01) allows water to flow into the ice maker. If it fails, no water enters. You can test it with a multimeter for continuity. A new valve costs around €30–€50 at local appliance parts stores in Spain, such as Recambios AEG or Electrorepuesto.

Check the Ice Maker Module

The ice maker module itself may be defective. Listen for a faint hum when the freezer is running; if you hear nothing, the module might need replacement. A replacement module (e.g., AEG 902979-02) costs about €60–€80. You can find them online at tiendas like Recambios AEG.

2. Ice Maker Producing Small or Hollow Cubes

If your ice cubes are small or have a hollow center, it usually means the ice maker is not getting enough water or the water flow is restricted.

Clogged Water Filter

Some AEG freezers have a water filter (e.g., AEG 902979-03). If it’s clogged, replace it. Filters should be changed every 6 months. A new filter costs around €15–€25.

Low Water Pressure

The ice maker requires a minimum water pressure of 1.5 bar. If your home’s pressure is lower, you may need a booster pump. Check with a pressure gauge; readings below 1.5 bar indicate a problem.

Partial Freeze in Water Line

A partially frozen water line reduces flow. Defrost the freezer completely (remove all food, unplug, leave door open for 24 hours). This can also fix other issues like ice jams.

3. Ice Maker Jamming or Producing Clumps

Ice clumps or jams can stop the ice maker from ejecting cubes. This is often caused by frost buildup or improper storage.

Frost Buildup in the Ice Bin

If the freezer door is left open or the seal is damaged, moisture enters and freezes, causing clumps. Check the door gasket for cracks. A replacement gasket for AEG models costs around €40–€60 and can be ordered from Recambios AEG.

Ice Bin Overfilled

Don’t overfill the ice bin. The ice maker needs space to drop cubes. If the bin is full, remove some ice.

Ice Maker Arm Stuck

The ice maker has a metal arm or sensor that stops production when the bin is full. If it’s stuck in the down position, the ice maker won’t cycle. Gently lift the arm to see if it moves freely. If it’s broken, replace the ice maker module.

4. Ice Maker Leaking Water

Water leaks around the ice maker can damage the freezer and floor. Common causes include:

  • Loose water line connection: Tighten the nut at the back of the freezer. Use a wrench but don’t overtighten.
  • Cracked water inlet valve: Inspect the valve for cracks. Replace if damaged.
  • Ice maker fill tube frozen: If the tube that fills the ice mold freezes, water can back up and leak. Defrost the freezer as described above.

If you have a persistent leak, it might be related to the freezer’s drain system. See our article on AEG Fridge Not Cooling for related drain issues.

5. Ice Maker Making Loud Noises

Unusual noises from the ice maker can be annoying but are often fixable.

Ice Ejector Gear Noise

If you hear a clicking or grinding sound, the ice ejector gears may be stripped. This requires replacing the ice maker module.

Water Valve Chatter

A buzzing or chattering sound from the water valve indicates a failing solenoid. Replace the water inlet valve.

Fan Noise

The condenser fan can make noise if it’s hitting ice or debris. Clean the fan blades and ensure nothing is obstructing them.

6. Ice Maker Produces Too Much Ice or Runs Continuously

If the ice maker never stops making ice, the shut-off mechanism is likely faulty.

Faulty Ice Bin Full Sensor

Most AEG ice makers use a thermistor or mechanical arm to sense when the bin is full. If the sensor fails, the ice maker keeps running. Test the sensor with a multimeter; if it shows no continuity, replace the ice maker module.

Control Board Issue

In rare cases, the main control board may be sending incorrect signals. Resetting the appliance (unplug for 10 minutes) can sometimes fix this. If the problem persists, consult a technician.

7. When to Call a Professional

While many ice maker issues can be fixed with DIY steps, some require professional help. Call a certified AEG technician if:

  • You suspect a refrigerant leak (ice maker not cold enough).
  • The compressor is not running.
  • You need to replace the main control board.
  • The ice maker is still under warranty (contact AEG Spain service at 900 100 118).
