Cookworks 5L Digital Air Fryer KDF-596D

Where to get real advice for this machine

Does it genuinely air-fry?

Genuine air frying

Genuine. A perforated frying tray sits inside a basket in a deep drawer with the element and fan above it, so air reaches every surface and fat drains below the food. The published ceiling of 200°C is inside the browning range, and a 5-litre drawer recovers temperature quickly after loading.

• Air reaches every surface of the food

• Fat and moisture drain away

What we know about this machine

Read from Cookworks 5L Digital Air Fryer KDF-596D — Care & Instruction Manual (PDF), retrieved on 2026-08-13.

It is rated at 1600 W, an ordinary domestic rating that recovers temperature reasonably quickly after cold food goes in. It has a single cooking drawer, so everything in it cooks at one temperature for one time. It runs from 50°C to 200°C, and the low end is genuinely useful: it is enough to dehydrate, prove dough or hold food warm. On preheating: has a preheat programme. It is sold as 5 litres, which measures the whole drawer including the space above the food that you must not fill.

The figures above are the manufacturer’s. What they mean for cooking is AirfryerHQ’s reading of them, not a measurement — nobody here has run this machine.

In the manual’s own words: A Preheat programme is published as one of the ten presets, at 180°C for three minutes. It is the only preheat in this catalogue with a stated duration on a drawer machine, and three minutes is a useful sanity check against the thirteen a countertop oven in this catalogue needs.

What each setting actually does

Read from the manual. The first column is the name printed on the panel; the second is what that setting is in plain terms, so you can use advice written for somebody else’s appliance.

• Cake: 160°C for cake, which is the figure four other manufacturers in this catalogue independently publish.

Questions owners ask about this machine

Answered from this model’s own manual (Cookworks 5L Digital Air Fryer KDF-596D — Care & Instruction Manual) and nothing else. Where the manual does not address a question, it is not answered here from another machine’s.

Before the first cookIs smoke or a smell on first use normal?

The manual says so twice. It attributes the odour to lubricant on the elements burning off, calls it normal and says it will not continue with further use; and it says a slight smoke or odour the first time will soon subside, with the room kept ventilated. Before that first use, wash the frying tray and basket.In the manual: Important safeguards, note 24; Before First Use; Using the appliance, note.

The parts, and how they go inWhat is the button under the clear cover on the handle?

The basket release. The manual's parts list names a clear button cover over a basket release button on the handle, and warns not to slide the cover and press the button while shaking, because the frying tray comes away from the basket and handle. Shake by the handle alone and use the button only once the tray is set down.In the manual: Know Your Appliance; Hot air frying, warning.

Settings the panel does not explainDoes Start/Pause switch it off?

No. The manual is explicit that Start/Pause only pauses the air frying; Power is what shuts the unit down. For food that needs shaking, the manual's tip is to set the timer to half the cooking time so the beep tells you when, then set it again for the rest.In the manual: Control panel notes; Using the appliance, tip.

How much goes in at onceHow full can I fill the basket?

The manual gives two instructions and no quantity: do not overfill the fry basket, and do not pack food into the frying tray. It adds that the frying tray and basket have a non-stick coating that metal utensils and abrasive materials may damage, without naming the material.In the manual: Using the appliance, notes 6 and 7; Cleaning.

The non-stick coatingWhat does the manual say about the coating?

That the frying tray and the basket have a non-stick coating, and that metal kitchen utensils and abrasive cleaning materials may damage it. The material is not named. To cool the machine faster before cleaning, the manual says to take the frying tray out.In the manual: Cleaning.What wears a coating, and when a part is finished

Error codes and display states

Only what this manufacturer publishes, and only for this manufacturer. A code means whatever the firmware author decided it means, and reading one across from another brand is the commonest way to misdiagnose a fault.

Cleaning this model

The parts this machine has, what collects on each and how often it needs doing. Full methods and prohibitions are on the cleaning pages.

The frying tray and basket are stated to be dishwasher-proof. The manual warns that the frying tray stays dangerously hot for about thirty minutes after use and must be handled by the handle only.

Faults the manual documents, as printed

Only what the manufacturer publishes. AirfryerHQ does not invent the meaning of an error code, and where a manual documents one undifferentiated fault state that is what appears here.

• The air fryer does not work

  Two causes are printed: the appliance is not plugged into the mains, or the timer has not been set.

  Put the plug in an earthed wall socket and set the time as the manual's Using the Appliance section describes.

• Results are undercooked or overcooked

  Too much food in the cooking tray, or a set temperature or time that was not correct. The manual says a preset's temperature and time will often need adjusting for the quantity and size of the food.

  Cook smaller batches, which the manual says fry more evenly, and raise or lower the temperature or time after choosing a food type.

• The ingredients are fried unevenly

  Some ingredients need to be shaken halfway through the cooking time.

  Shake ingredients that lie on top of or across each other, such as fries, halfway through.

• Fried snacks are not crispy

  A type of snack meant for a traditional deep fryer was used.

  Use oven snacks, or lightly brush some oil onto the snacks.

• Cannot slide the tray into the appliance properly

  Too much food in it, or the tray is not placed in the unit correctly.

  Reduce the amount in the basket, and push the tray fully into the unit until it clicks.

• White smoke comes out of the appliance

  Greasy ingredients, or greasy residues left in the tray from the previous use. The manual says white smoke is caused by grease heating up in the bottom of the tray under the basket.

  For greasy foods the manual says it may be necessary to set a temperature below 180°C. Clean the tray properly after each use.

Recall and safety status

No recall known to us at the review date

No entry for this model was found in the OPSS product safety register when it was searched for air fryers on 13 August 2026. That is a statement about that search and not a clearance.

No verified recall or safety notice is currently recorded in AirfryerHQ for this appliance. That is a statement about this catalogue and not about the product: AirfryerHQ holds a small number of checked alerts and is not a copy of the UK register. Check the authority's own register before concluding that an appliance is unaffected.

The Office for Product Safety and Standards publishes the UK register of product safety alerts, reports and recalls on GOV.UK, and Electrical Safety First operates a recall checker for electrical appliances. Registering an appliance with its manufacturer is what makes a direct notification possible.

Finding the manual

The document read for this page is Cookworks 5L Digital Air Fryer KDF-596D — Care & Instruction Manual (PDF), retrieved on 2026-08-13. A different revision, or a booklet for another market, may not match it.

The preset table is the whole value of this manual. It publishes what each button does, which almost no manufacturer does, and it publishes it as a starting point rather than as a validated cooking time for a stated quantity — a distinction the model page keeps.

About this model

An unremarkable machine with an unusually useful manual. Only three manuals in this catalogue publish a default temperature AND a default time AND a settable range for every programme, and this is one of them — which makes it the clearest available answer to the very common question of what a preset button actually does.
