The short answer
On a Bertazzonii refrigerator, ice maker fault most often comes down to the water supply is off, kinked or frozen. Supply and filter lead here because these cabinets are usually plumbed in as part of a kitchen installation, and a supply valve behind cabinetry is the one part of the system nobody has looked at since the day it was fitted. Most of what follows is an owner check; it becomes a service call when water reaches the mould, the freezer is properly cold, and no harvest happens.
What you are actually seeing
- The entries at the end belong to a different fault and send you elsewhere.
- No ice at all, with the mould in the ice maker either empty or holding an unfrozen puddle.
- Cubes that are hollow, small, or fused into a solid block.
- The ice maker fills and overflows down the back of the freezer.
- If instead you see this: The freezer is not properly cold — read the cooling-failure page first; an ice maker will not run reliably in a freezer above its working temperature.
Ranked causes on a Bertazzonii refrigerator
- Supply and filter lead here because these cabinets are usually plumbed in as part of a kitchen installation, and a supply valve behind cabinetry is the one part of the system nobody has looked at since the day it was fitted. Settle one observable question before you use this ranking — integrated column versus freestanding cabinet: a column bolted to a rail and sitting flush with the cabinetry is integrated, while a cabinet on its own levelling feet with a gap behind it is freestanding. Open the door and look at the top hinge.
- The water supply is off, kinked or frozen — Why: A closed shut-off valve, a hose kinked behind the cabinet during a move, or a supply line frozen where it passes through the cold section.
- A clogged or wrongly seated water filter — Why: A restricted filter starves the fill, giving hollow cubes and short fills before it gives none at all.
- The shut-off arm or sensor thinks the bin is full — Why: A lifted arm or a blocked infrared sensor stops production immediately, and it is the state a bin of ice knocked sideways will produce.
- The freezer is not cold enough for a full harvest — Why: Ice makers harvest on a temperature threshold.
- The fill tube is frozen — Why: A slow seep at the valve freezes in the fill tube and blocks it.
What to check, and why in this order
- Free checks first, then the ones that need the machine opened.
- Confirm the freezer is properly cold before anything else.
- Then confirm the machine is being offered water at all: valve open, line not kinked, filter seated and not overdue.
- Then check the shut-off arm or sensor, because it stops production silently and completely.
Checks you can safely do yourself
- Stop at the first step that would need a meter on live terminals.
- Measure the freezer temperature with a thermometer left in it for several hours. — Number: 1 — Tools: freezer thermometer — Time: a few minutes to set up, several hours to read
- Trace the supply line from the cabinet back to its shut-off valve and confirm the valve is open and the line is not kinked or crushed behind the cabinet. — Number: 2 — Tools: torch — Time: under ten minutes
- Lift the shut-off arm and let it fall, or clear the area in front of the sensor eye. — Number: 3 — Tools: none — Time: a few minutes
- Reseat or replace the water filter if the cabinet has one, and run water through a dispenser if fitted until it flows clean and steady. — Number: 4 — Tools: replacement filter if due — Time: under half an hour
Before you start
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Nothing below asks you to put a meter on live terminals, and nothing below asks you to defeat a door switch or an interlock — those exist to cut power to something that would otherwise hurt you. If the plug, the cord or the outlet is warm, discoloured or smells hot, stop there and have the circuit looked at before you use the refrigerator again.
When to stop and call a technician
The line is whether the next step needs live testing, sealed-system access or a part you cannot verify. Call for a sealed system, and any column that has to come out of its cabinetry to be reached, or when:
water reaches the mould, the freezer is properly cold, and no harvest happens the fill tube refreezes within days of being cleared, which points at a seeping valve water overflows down the back wall every cycle

Common BERTAZZONII Refrigerator Problems (bertazzonii-refrigerator-problems)
This page is generalized across the Bertazzonii refrigerator range: it is written for the brand and the fault, not for one family or one model number. It carries no model-specific code table, wiring detail or part number, and no measured failure rate, because no measured snapshot was available here. Where a family- or model-specific page exists beneath this one, the links below go down to it.
