Tower T17021 Guide: 3.2L Basket, Parts & Used Checks

Tower T17021 capacity: Tower’s current replacement-part pages distinguish a 4.3 L outer pot from the 3.2 L removable cooking basket. Use 3.2 L when judging usable food capacity. Both official part listings specify simple hand washing, so do not rely on older claims that these T17021 parts are dishwasher-safe.

Item	Current verified detail	Why it matters
Model family	T17021; Tower also lists T17021RG compatibility for the outer pot	Check the complete code on the rating label before ordering parts
Outer pot	Part T17021002; 4.3 L	This is not the same as usable basket volume

Cleaning	Official spare pages specify hand washing	Avoid unsupported dishwasher claims
Rubber foot	Part T17024002; listed for T17021 and T17024	Compatibility is part-specific, not universal across Tower fryers

Why 4.3 L and 3.2 L both appear

The two figures describe different components. Tower identifies the black outer pot T17021002 as 4.3 L and the removable basket T17021001 as 3.2 L. Food sits in the basket, so 3.2 L is the more useful number when estimating portions or comparing this model with a modern air fryer.

Calling the T17021 simply a “4.3 L air fryer” can make it sound substantially larger than its food basket. It is safer to describe it as a model with a 4.3 L outer pot and a 3.2 L basket. For broader sizing help, see the air-fryer size guide.

Who the T17021 suits

A 3.2 L basket is most credible for one or two people, snacks, sides or modest batches. It can still prepare food for more people when used as a side-dish appliance, but it should not be presented as a guaranteed one-batch family-of-four machine. Food shape and the exposed basket floor matter more than a serving claim.

Good fit: chips or vegetables for a small household, one or two proteins, reheating, or an additional side beside an oven.
Less suitable: a complete family dinner, broad baking dishes, large joints or meal prep that needs several portions in one cycle.
Before replacing it: check whether a genuine basket or outer pot is available and whether the appliance itself is still electrically sound.

Verified replacement parts

Component	Tower reference	Compatibility shown by Tower	Care note
Cooking basket	T17021001	T17021	3.2 L; hand wash
Outer pot	T17021002	T17021 and T17021RG	4.3 L; hand wash
Rubber foot	T17024002	T17021 and T17024	Check all feet before use

The references identify parts; they do not guarantee current stock, delivery to your country or compatibility with any model not explicitly listed. Recheck the Tower page before ordering.

Do not confuse T17021 with T17023

Tower’s current official product page identifies T17023 as a different appliance: a 1,000 W, 2.2 L manual air fryer. Similar-looking Tower model numbers are not capacity variants of the same machine. Use the rating label, not a retailer title or an image alone, when identifying a used fryer or replacement part.

This also means a basket, drawer or recipe-book reference containing another T170xx code is not proof of hardware compatibility. Tower’s own support guidance directs owners to the product page or Consumer Care when the correct manual or part cannot be found.

What is not currently verified

The original article repeated temperature, timer, weight and performance claims without linking an official T17021 manual or live product page. Tower’s current public site exposes the T17021-compatible parts above but not the main product listing. We therefore do not present those repeated values as confirmed specifications.

If you own the appliance, use the rating label and original manual as the primary evidence. Tower says manuals are normally available from a product page and directs owners to Customer Services when the manual cannot be found online. Do not copy settings from the current T17023 page: it is a different 2.2 L model.

Safe cleaning for the T17021 parts

Unplug the appliance and allow it to cool completely.
Release the basket from the outer pot according to the original manual.
Hand-wash both parts with warm water, mild detergent and a soft sponge.
Avoid metal utensils and abrasive pads on coated surfaces.
Wipe the main unit with a slightly damp cloth; never immerse the electrical housing.
Dry the basket and pot completely before reassembly.

For general technique, use the air-fryer cleaning guide. The exact manual and part instructions take priority. Our guide to dishwasher-safe air-fryer parts also explains why removable does not automatically mean dishwasher-safe.

Used-buying checklist

Confirm the rating label says T17021 or the exact variant being advertised.
Check that basket T17021001 and outer pot T17021002 are present and latch together correctly.
Inspect the basket coating for chips, deep scratches or exposed metal.
Check the handle, release mechanism, cable, plug and strain relief for damage.
Make sure the appliance sits level and all feet are intact.
With the owner present, test that the fan, heater, controls and safety interlock operate without unusual noise, smoke or burning smell.
Do not pay a premium based on “4.3 L basket” wording; Tower lists the basket itself as 3.2 L.

Repair or replace?

A worn basket or outer pot can be a reasonable repair when a genuine compatible part is available and the electrical appliance is otherwise sound. Replace the whole unit if the cable, plug, heater, fan, controls or safety interlock are damaged, or if the cost and availability of parts no longer make sense.

When moving to a newer appliance, compare usable basket area rather than the T17021 outer-pot figure. The air-fryer parts guide shows how the basket, outer drawer or pot, crisper plate and main housing differ.

Verdict

The Tower T17021 can still be useful as a compact small-batch fryer, but it should be assessed as a 3.2 L basket appliance—not as a 4.3 L food basket. Its clearest present-day advantage is that Tower still documents several exact compatible parts. Its main limitations are modest usable capacity and the absence of a current public T17021 product page with a complete specification sheet.

How this guide was researched: this is specification-led ownership guidance, not a hands-on test. The capacity, compatibility and cleaning statements were checked against Tower’s current official basket, outer-pot, rubber-foot, product and support pages on 23 October 2026. Specifications not supported by a current official T17021 page or manual were deliberately omitted.

Frequently asked questions

Is the Tower T17021 4.3 L or 3.2 L?

Tower lists the outer pot as 4.3 L and the removable cooking basket as 3.2 L. Use 3.2 L when estimating usable food capacity.

Can the T17021 basket go in the dishwasher?

Tower’s current basket and outer-pot pages specify simple hand washing. Follow that current manufacturer guidance unless your original manual explicitly states otherwise for your exact variant.

What is the T17021 replacement basket number?

Tower identifies the black 3.2 L basket as T17021001 and lists it for the T17021.

What is the T17021 outer-pot number?

Tower identifies the 4.3 L outer pot as T17021002 and lists it for T17021 and T17021RG.

Is Tower T17023 the same as T17021?

No. Tower’s current T17023 page describes a separate 1,000 W, 2.2 L manual air fryer. Do not use the similar model number as evidence that parts or specifications match.

Is the T17021 large enough for four people?

The 3.2 L basket can prepare snacks, sides or modest portions for several people, but a complete four-person meal will often require batches or another appliance. Food shape and basket floor area determine the practical limit.
