Fisher & Paykel DD24SI9 Single DishDrawer Dishwasher Review

The DD24SI9 N (SKU 82342) is a single-drawer, fully integrated, panel-ready dishwasher from Fisher & Paykel's Series 9 line. It pulls out as a drawer instead of dropping a door, and it sits under the counter at roughly waist height so you load it standing up. It is built into cabinetry and finished with a custom cabinet panel or an optional stainless panel, so it disappears into the kitchen run.

The drawer is 16 1/8 inches tall. It is ADA compliant and can be installed at accessible height. It connects over Wi-Fi for alerts, monitoring, software updates and setup.

The case for this machine rests on how it is loaded and where it fits, not on raw capacity.

Loading at counter height

You load and unload standing up, with one hand, at the height of the counter. There is no door to swing and no rack to pull out, and no bending to reach the bottom of a tub. For anyone with a bad back, a knee replacement or a kitchen designed for aging in place, that is the whole point.

Disappearing into the cabinetry

The front takes a custom cabinet panel or the optional stainless panel, so the dishwasher reads as another drawer in the run. It is also the way to get a panel-ready dishwasher into a 16 1/8-inch-tall space: under a lowered counter, in an island, in an accessible kitchen or in a wet bar.

Efficient small loads

Each wash cycle uses 1.64 gallons, and the machine is rated at 144 kWh a year with Energy Star certification. The efficiency case holds when you actually run small loads often, which is exactly what the drawer is built for.

Quiet running and a sanitizing rinse

The noise level is 43 dBA. The Sanitize modifier kills 99.9% of bacteria in the final rinse, which matters for baby bottles, cutting boards and anything used with raw meat.

Knock to pause

A tap on the front panel pauses the cycle, and the start button resumes it. It is the fastest way to drop in a glass you forgot.

Programs and a flexible interior

There are six wash programs (Delicate, Eco, Fast, Heavy, Medium, Rinse) and three modifiers (Quick, Sanitize, Extra Dry). Inside, the cup racks fold and adjust in height, the tines fold down and adjust in pitch, and a cutlery basket comes in the box. Round plates up to 11 inches fit.

Smart extras

Wi-Fi brings alerts, monitoring, software updates and onboarding. A 12-hour delay start, a key lock, a rinse-aid indicator, end-of-cycle beeps and a fault indicator round out the controls.

The limits are real and they show up in daily use, not on the spec sheet alone.

Capacity

Seven place settings is the capacity figure given for this dishwasher. You will run it more often than a full-size dishwasher. It covers about a day of dishes for a small household, or one dinner party's plates and glassware.

Long cycles

The small water volume plus on-board heating means long runs. Medium takes roughly two to two and a half hours, and Heavy and Eco run around three hours. Fast is roughly 35 to 45 minutes, but it is meant for lightly soiled loads. The countdown on the display is an estimate and stretches when the inlet water is cold.

Drying

Fan-assisted drying runs after the wash and stops when you open the drawer. Plastics stay wet unless you switch on Extra Dry. Water can also pool on the top lip and seal, which is normal for the format.

Loading is a skill

The single shallow rack rewards a specific loading pattern. Bowls, tall glasses and odd cookware fight it, and a dish placed wrong can block the detergent dispenser. There is no cutlery tray option, only the cutlery basket.

The panel and handle are not included

The custom panel and the handle are sold separately. A cabinetmaker has to make and fit the panel to a minimum height of 16 1/16 inches, a width of 23 7/16 to 24 3/16 inches, a thickness of 5/8 to 13/16 inch, and a maximum weight of 20 pounds including the handle. Leave a 1/16-inch ventilation gap below the panel and a small gap behind it to prevent condensation damage. Optional stainless panel and handle kits are available separately.

Warranty

The warranty is a limited 2 years on parts and labor, which is short for an appliance at this level.

Reliability reputation

Independent reliability surveys have rated the drawer category poorly for predicted reliability, but that is a category-level result from an older survey, not a current verdict on this model.

These are the figures that decide whether the drawer fits your cabinet and your routine.

The 16 1/8-inch height is what lets the drawer slide under a standard or lowered counter, and the 20 3/4-inch extension tells you how much floor space the open drawer needs in front of it. The 35-pound weight means one person can lift it into the cavity, though two make the job easier. The 3/8-inch compression fitting and the 15 A circuit are what a plumber and an electrician will look for before the install day.

Most of the trouble with this machine happens before the first wash, at the cabinet opening and the panel.

Height decision

The DD24SI9 is the standard-height single drawer at 24 inches, which is the pick for standard under-counter and accessible installations. A shorter single-drawer variant exists at 17 7/8 inches for kitchens with the cavity height and a need for more plate room. Measure the opening before you order, not after.

Cavity check

Confirm a minimum opening of 16 7/32 inches high, 23 5/8 inches wide and 22 13/16 inches deep, plus the toe-kick clearance if the unit vents through it. Check the 1/2-inch clearance to a corner cabinet and the 1/16-inch clearance to an adjacent cabinet door.

Panel and handle

The custom panel is not included and has to be made by a cabinetmaker to the dimensions above. The optional stainless panel and handle kits are available separately, and a handle kit is required for a single drawer.

Accessible installation

The drawer is ADA compliant and can be installed at accessible height, which is one of the reasons it exists in this format.

Leveling

Leveling is critical. An unlevel unit can leak mid-cycle, so run check cycles before the installer leaves and watch the seals and the floor under the drawer.

Service network

The service network is thinner than those of the large US appliance brands, so check that an authorized technician covers your area before you buy. That is a practical ownership consideration, not a defect of the machine.
