The short answer
The order that matters here is a unit that is filled by hand rather than plumbed first, the water supply to the unit next and the water filter last. On a compact import-channel unit the surroundings come first. There is very little mass and very little margin in these machines, so where one stands changes how it behaves. That ranking is the value of this page: the cheap causes are the common ones on Nova refrigerators, and the costly one is what people reach for first.
What you observe
- A sheet of ice in the bottom of the freezer — The fill tube is icing and overflowing, which is a distinct and common fault.
- No ice at all, and the bin is empty — Either no water is arriving or the maker is switched off — both are checked in a minute.
- A stale taste to the ice — Old ice absorbs odours. It is a sign of very slow production rather than a fault in itself.
- NEAR MISS — the whole freezer is soft and the ice is melting — That is a cooling failure, and the cooling page is the correct read. Ice is the symptom, not the fault.
Causes, most likely first on Nova
- A unit that is filled by hand rather than plumbed — On a unit like this the whole supply side of the diagnosis is different. There is no valve, no filter and no line — there is a tank, a sensor and a pump, and any of them can stop production with the appliance otherwise perfect. Placed there because it is first here because the supply question on these units is answered by looking into a tank rather than behind the appliance.
- The water supply to the unit — Everything starts at the shut-off valve behind or under the unit. Close behind, and rarely far from the top on any machine: nothing else can be judged while the supply is in doubt, which is exactly why it leads.
- A freezer that is not cold enough — An ice maker will not run a harvest cycle until the mould has reached its release temperature. Third on this brand: this belongs above the mechanical causes because a warm freezer stops a perfectly healthy ice maker.
- The water filter — A filter at the end of its life restricts flow enough that the mould never fills properly. Last: this position reflects how often the fault appeared within days of the filter being touched.
Check in this order, and why
- First: Check the reservoir and its sensor — Fill it to the mark and wipe the level sensor; scale on the sensor reads as an empty tank. It is first because it is the cheapest of the three to settle.
- Second: Check the shut-off valve and the line — Make sure the valve is fully open and the line is not crushed where the unit was pushed back.
- Third: Measure the freezer temperature — A freezer holds food safely at 0 °F (−18 °C) or below; above that, ice production suffers first.
What an owner can safely check
- Fill the reservoir and clean the level sensor — Empty it, wipe the sensor contacts and the tank, refill to the mark and restart the cycle.
Tools: clothAbout 15 min
- Open the valve fully and straighten the line — Pull the unit out, check the valve is fully open, and free any kink in the supply line.
Tools: torchAbout 20 min
- STOP HERE if the next step needs a meter on live terminals — That is the line between an owner check and a service call, and it is not worth crossing.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel, and treat every capacitor as still charged: a capacitor can hold a charge after the power is off. Do not attempt anything on the sealed system: refrigerant work is licensed work. Never chip ice off an evaporator with anything metal, because piercing a coil ends the appliance.
When to call a technician
The owner side of this is the valve, the filter, the arm and a thermometer. Past that it is a service call.

What this page does not cover
This is generalized information for Nova refrigerators as a class, not for one family or one model. No family- or model-specific page for this brand and appliance is published here yet, so nothing narrower is linked; when one is, it becomes the more specific answer and this page will point to it. Not here: wiring colours, torque figures, part numbers and panel-removal sequences, all of which differ by family.
