AEG Australia lists a 560 x 490 mm cutout, 590 x 520 x 55 mm overall dimensions and a 7.4 kW connected load. The manual documents the zone sizes and minimum pan diameters; public sources do not provide enough independent evidence to make a reliable verdict on long-term reliability.
What the HK673520FB is—and its availability
AEG Australia identifies the HK673520FB as a 60 cm Pure 3 OptiZone full-induction cooktop and marks it discontinued. That status describes AEG Australia’s listing; availability and replacement options can differ by country and depend on current local stock. Do not assume that new units are readily available.

AEG lists a black ceramic-glass surface, three cooking zones, OptiZone pan detection and a bridge function. The manufacturer describes the bridge this way: “The Bridge function allows you to connect two cooking zones to fit large pots or long pans.” These are listed features, not independent test results. AEG Australia’s product page has the regional product details.

Dimensions and installation requirements
| Specification | HK673520FB |
|---|---|
| Overall dimensions | 590 x 520 x 55 mm (AEG Australia) |
| Cutout dimensions | 560 x 490 mm (AEG Australia) |
| Zones | 3 |
| Connected load | 7.4 kW |
| Connection listed for Australia | Hardwired |
Use these dimensions as checks for a qualified installer, not as do-it-yourself installation instructions. A replacement may fit the cutout but still differ in overall size, electrical requirements or connection method. Have an appropriately qualified professional confirm the cabinetry opening and supply requirements for your location before purchase or installation. Specifications can vary by market, so consult the current regional documentation.

Zones, power and cookware compatibility
The manual identifies two 210 mm zones on the left and a right zone listed as 180/280 mm. It gives these nominal and power-function figures:
| Zone in the manual | Diameter | Nominal power | Power-function rating | Minimum pan diameter |
|---|---|---|---|---|
| Left rear | 210 mm | 2300 W | 3200 W | 125 mm |
| Left front | 210 mm | 2300 W | 3200 W | 125 mm |
| Right rear | 180/280 mm | 1800/3500 W | 2800/3700 W | 145 mm |
The manual says delivered power can vary somewhat with cookware material and dimensions. The stated minimum diameters are useful compatibility checks, but they do not establish how evenly or quickly a particular pan will heat. For a used cooktop, test the cookware you actually intend to use where possible, and consult the HK673520FB manual for operating and cookware guidance.

Controls and listed functions
AEG lists DirekTouch controls and a broad set of functions: OptiZone, bridging, OptiHeat, Automax, Stop + Go, Powerbooster, CountUp and Oko timers, a minute minder, control lock, automatic safety shutoff, child lock, power management, sound control, induction technology and pan sensing. Feature names alone do not show how intuitive the controls are in daily use or how well the cooktop performs; those require hands-on or independent testing.
What independent and owner evidence can—and cannot—tell you
CHOICE has a model page for the HK673520FB and identifies it as discontinued. Its public page lists three zones, 60 cm width, a 7.4 kW maximum capacity, dimensions of 59 x 52 cm and installation dimensions of 56 x 49 cm. The expert rating and merits, along with sustainability, reliability and satisfaction information, are member-only or unavailable on the public page. The page therefore does not support a claim that CHOICE rated the cooktop well or poorly. See CHOICE’s HK673520FB page.

- Condition: Inspect the glass for cracks or chips, and check the controls and each zone. If anything appears damaged or behaves inconsistently, have it assessed by a qualified service professional.
- Fit: Ask an installer to verify the cutout and overall dimensions against the actual cabinetry and the regional product documentation.
- Electrical compatibility: Confirm the required connected load and connection arrangement with a qualified installer. AEG Australia lists 7.4 kW and hardwiring for its specification.
- Service access: Check local parts availability, repair options and warranty terms before committing to a used appliance. AEG’s regional support page provides routes to repair booking and accessories or spare-parts discovery; the appropriate service route depends on your country.
- Replacement comparisons: Compare cutout and overall dimensions, zone layout and large-pan capability, electrical requirements, control and safety functions, warranty, local service access and independent test results. Current alternatives and their availability are not established here, so verify any candidate model with its manufacturer and local seller.
Verdict
The HK673520FB’s documented specifications make it possible to check whether its dimensions, three-zone layout and electrical requirements suit an existing kitchen. Its discontinued status makes local availability and service worth checking carefully. The manual is useful for cookware and operating details, but the public evidence does not establish a balanced reliability verdict: CHOICE’s substantive result is not public, and the small set of owner reviews is anecdotal.

- Induction stoves rely on cookware to heat, so it’s essential to choose magnetic bottom cookware with a minimum diameter of 5 inches. Auto-pan detection will shut off automatically after 60 seconds if no cookware, or the incorrect cookware is detected
- Although induction itself is a noiseless process, there may be high pitched sounds from the cookware due to multiple layers of metals sandwiched together. Please allow the induction cooker to cool down before cleaning
