The Liebherr Fdi1624 is a built-under, under-counter freezer designed for households that want reliable freezing performance without giving up much floor space. With 107 litres of capacity, it comfortably handles a weekly top-up shop while still slipping neatly under a standard worktop.
Liebherr is known for its refrigeration expertise, and that comes through here in the thoughtful feature set: adjustable storage, fast-freeze functions and smart protection against temperature swings. It feels more premium than many basic under-counter models.
Owners clearly rate it highly, with an excellent average user score of 4.8 out of 5 from a solid number of reviews, suggesting real-world satisfaction with both performance and build quality at its current price point.
The Liebherr Fdi1624 is ideal for small to medium households that need extra freezer space but don’t have room for a full-height unit. At 85cm high and 60cm wide, it tucks neatly under a standard kitchen worktop, making it a good choice for flats, smaller kitchens or as an overflow freezer in a utility room.
It suits buyers looking for something a step up from entry-level. The D energy rating, low noise level and feature set place it firmly in the mid to upper segment of under-counter freezers, so it’s better suited to those willing to pay a bit more for efficiency, quiet running and flexibility.
If you batch cook, buy in bulk or like to keep popular frozen favourites always on hand, the 107-litre capacity and VarioSpace design are very handy. You can remove drawers and adjust the layout to accommodate taller boxes or jointed meat without a struggle.
It’s also well suited to anyone who values food protection. Features such as SuperFrost, over-temperature alerts, door open alarm and 14-hour safe storage during a power cut are reassuring if your freezer is regularly well stocked.
Generous 107-litre capacity in a compact under-counter footprint means you can add meaningful freezer space without sacrificing a large area of the kitchen.
SmartFrost helps reduce icy build-up compared with traditional static freezers, so you’ll spend less time defrosting and have more usable space in the drawers.
SuperFrost rapidly drops the temperature to around -32°C when you add new groceries, helping lock in freshness and preventing existing food from warming up. Great if you regularly do big freezer shops.
VarioSpace and four baskets make the interior genuinely flexible. You can remove drawers and some shelving to fit bulkier or taller items, rather than wrestling them into awkward spaces.
A low 36 dB noise level is impressively quiet for a freezer, making it well suited to open-plan kitchens or smaller homes where appliance noise can be intrusive.
Practical safety features – including a door open alarm, over-temperature alert and 14-hour power-failure safe storage – offer real peace of mind if something goes wrong.
Touch controls with an LCD display on the door give the freezer a modern, upmarket feel and make it easy to check and adjust the temperature at a glance.
This isn’t a frost-free model, so while SmartFrost reduces ice build-up, you will still need to defrost it manually from time to time.
The D energy rating is respectable but not class-leading by today’s standards. There are A–C rated models available, though often at a higher price or with fewer features.
The 1-year manufacturer warranty is on the short side for a premium-feeling appliance; some rivals offer longer cover for extra reassurance.
The right-hand hinge is reversible, but swapping it over will add a bit of installation faff if you need the door to open the other way.
Day to day, the Liebherr Fdi1624 feels like a thoughtfully designed appliance. The under-counter size means it integrates cleanly into a fitted kitchen, and at standard 60cm width and 60.7cm depth, it should slide into most existing gaps with minimal adjustment.
The internal layout is straightforward: four baskets and three main compartments give you a clear view of what’s inside. VarioSpace makes a real difference – you can remove baskets to create taller sections for large joints, stacked containers or bulky frozen desserts, rather than juggling items around.
Touch controls and the LCD display on the door keep operation simple. You can quickly activate SuperFrost before a big shop, then switch it off once everything is frozen again. The display also makes it clear if the temperature isn’t where it should be.
At 36 dB, the freezer runs very quietly, so it fades into the background noise of the home. LED interior lighting makes it easy to see what’s in the drawers, even in a dim utility room. When the door is left open, the alarm gently prompts you to close it, which helps avoid accidental thawing.
Maintenance is relatively light. SmartFrost means the interior frosts up more slowly than basic static models, so defrosting sessions are less frequent and generally quicker, though not completely eliminated.
With a 107-litre net capacity, the Fdi1624 offers enough room for roughly five bags of frozen food, making it a solid main freezer for smaller homes or an excellent secondary freezer for larger families. The four-basket layout makes it easy to separate everyday items from longer-term storage.
The performance highlights are all about temperature control. SuperFrost rapidly drops the internal temperature to -32°C when activated, so new groceries freeze quickly and don’t compromise what’s already stored. This is particularly useful after a large supermarket trip or when portioning home-cooked meals for the freezer.
SmartFrost improves on traditional static freezers by reducing frost formation on the interior walls and the contents themselves. This not only helps you maintain a more consistent temperature but also means drawers slide more easily and usable space is maximised.
For safety and food protection, the Fdi1624 is well equipped. A door open alarm and over-temperature alert warn you if something is wrong, and FrostProtect helps the freezer continue to operate reliably even in cooler ambient temperatures, such as garages or utility rooms within the specified climate class (SN–T). In the event of a power cut, your food is protected for up to 14 hours, which is reassuring if you live in an area prone to outages.
The LED interior light and on-door LCD display with touch controls round out the feature set, making it easy to see contents and manage settings. While it isn’t a no-frost model, the combination of SmartFrost and efficient design means performance is more stable and maintenance lighter than you’d get from a very basic under-counter freezer.
Positioned at the higher end of typical under-counter freezer pricing, the Liebherr Fdi1624 isn’t the cheapest option on the market, but it does justify much of its premium. You’re paying for a well-built appliance from a refrigeration specialist, with features usually reserved for more expensive models.
The D energy rating and annual energy consumption of around 137 kWh are reasonable for a compact freezer of this size and spec, helping to keep running costs in check over the long term. When combined with the very quiet 36 dB operation and solid four-star freezing performance, it feels like a considered purchase rather than a simple budget buy.
Crucially, the strong user rating of 4.8 out of 5 from 24 reviews suggests that owners feel they have received good value. If you’re prepared to invest a little more upfront for quieter running, better temperature control and flexible storage, the Fdi1624 represents good long-term value. If you just want the cheapest possible extra freezer space and can live without the extra features, there are more basic models that will cost less.
The Liebherr Fdi1624 is a polished under-counter freezer that focuses on quiet, reliable performance and clever storage rather than gimmicks. Its 107-litre capacity, VarioSpace layout and SmartFrost technology make it far more practical than basic compact models, while SuperFrost and robust safety alerts help protect your food in everyday use.
It’s not perfect – you still need to defrost it occasionally, the energy rating, while decent, isn’t top-tier, and the 1-year warranty feels modest for a premium-leaning appliance. However, the very positive owner reviews and thoughtful specification suggest Liebherr has got the fundamentals right.
If you’re looking for an under-counter freezer that feels solid, runs quietly and offers a genuinely flexible interior, and you’re willing to spend a bit more than entry-level, the Fdi1624 is an excellent choice. Budget hunters might look elsewhere, but for most households wanting dependable extra freezer space with a touch of sophistication, it’s a strong contender.
