The short answer
On Forno an ice maker that has stopped is most often a frozen fill tube. Ranked that way because the cabinet is trimmed into a run of joinery, so installation faults outlive the install and keep presenting as appliance faults.
What you observe
- The mould is full of ice that never drops — Filling works and harvesting does not, which is a much shorter list.
- Ice arrives, but far more slowly than it used to — A gradual decline usually means a filter or a valve rather than a sudden failure.
- NEAR MISS: there is water on the floor as well as no ice — Then you have a supply leak, and that page is the one to read first. Shut the supply valve before anything else.
Causes, most likely first on Forno
- The fill tube or the line in the door has frozen — First on a fitted machine, which is only ever as good as its installation. Water sits in the last section of the fill tube between cycles. If the compartment runs colder than it should, or the tube has shifted out of position, that water freezes and the next fill never arrives.
- The water supply is off, kinked or barely open — Second: on a fitted machine this is the next thing genuinely yours to check. A shutoff valve half closed after other work, a supply line crushed behind the cabinet when it was last pushed back, or a saddle valve that was never opened properly. The machine calls for water and very little arrives.
- The inlet valve or the filter is restricting flow — Third. A partly blocked filter or a tired inlet valve lets through enough water to half-fill the mould, which produces hollow, undersized or crescent-shaped cubes rather than none at all.
- The ice maker module, ejector or mould heater has failed — Last, and it is the reason the order above matters. The mould fills and never releases, or the motor never turns.
Check in this order, and why
- Look for an ice plug at the fill tube where it enters the ice maker — A visible plug is a confirmed cause and it explains a maker that filled yesterday and not today.
- Trace the supply line from the valve to the cabinet and look for kinks — A crushed line behind the unit is common and completely invisible from the front.
- Look at the cubes you are getting: hollow or undersized points upstream at flow — The shape of the ice tells you about the water before you touch anything.
What an owner can safely check
- Warm the fill tube gently with a cloth soaked in warm water — Never use a flame or a heat gun.
Tools: cloth, warm waterAbout 20 min
- Find the shutoff valve, confirm it is fully open, then ease the cabinet out and inspect the line — Look for a sharp bend where the cabinet was pushed back against the line.
Tools: torchAbout 20 min
- Replace the water filter if one is fitted and run several fills through — Discard the first batches after any filter change.
Tools: replacement filterAbout 20 min
- STOP HERE if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Shut the water supply valve before disconnecting any line, and have a towel and a bowl ready because the line stays charged after the valve closes. Unplug the appliance or switch off its breaker before removing any panel near the ice maker. Never thaw a frozen fill tube with a flame, a heat gun or a naked bulb: the liner and the tube are plastic and they will deform long before the ice gives up.
When to call a technician
Call when the supply is proven good, the freezer is cold enough and the mould still will not release, because that puts the fault in the module and it is replaced as an assembly. Call sooner if you find water anywhere it should not be, or if the freezer is sitting warm, because then the ice is a symptom of something larger and the cold matters more than the cubes do.

What this page does not cover
This page covers the brand and the refrigerator class, not one family or model line. Where a family-specific or model-specific page exists for your unit, that page is the more specific answer and it takes precedence over this one. Not here: part numbers, wiring colours and component locations, which differ by family.
