The short answer
On Fisher & Paykel an ice maker that has stopped is most often a water supply that is off, kinked or barely open. Ranked that way because the variable-speed compressor modulates rather than cycling, so a fault shows as a cabinet that never quite arrives rather than as a unit that stops.
What you observe
- Cubes are hollow, small or misshapen — Water is arriving but not enough of it, which points upstream at flow rather than at the maker.
- The mould is full of ice that never drops — Filling works and harvesting does not, which is a much shorter list.
- 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 Fisher & Paykel
- The water supply is off, kinked or barely open — First here, where a modulating control hides a developing fault rather than announcing it. 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 fill tube or the line in the door has frozen — Second, and the cause this control is least able to tell you about. 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 freezer is not cold enough to trigger a harvest — Third. The maker will not eject until its mould reaches its release temperature.
- 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
- 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 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.
- Put a thermometer in the freezer overnight and read it in the morning — It separates an ice-maker fault from a refrigeration fault with one measurement.
What an owner can safely check
- 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.

- Warm the fill tube gently with a cloth soaked in warm water — Never use a flame or a heat gun.

- Leave an appliance thermometer in the freezer overnight — A freezer holds food safely at 0 degrees Fahrenheit or below.

- 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.
