How Cove and Bosch dishwashers differ
The Cove 24-inch DW2451 lists from about $2,935 panel-ready to $3,160 with a stainless door kit and pro handle. The Bosch Benchmark lists around $1,999 in stainless. Both offer panel-ready versions, so either can disappear into cabinetry.
Cove is built to match Sub-Zero and Wolf: 12 wash cycles, 6 add-on options, 45 spray jets across 3 spray arms, a 4-stage fine mesh filter, an adjustable middle rack with a stemware rail, four interior LEDs and a fastenerless stainless interior. Leak protection uses a conductivity sensor. Cove doesn't publish place settings for this model.
Bosch counters with CrystalDry, PrecisionWash with a PowerControl spray arm, a flexible third rack, ZoneControl, AquaStop and a built-in water softener. It's ENERGY STAR at 240 kWh a year.
In short, Cove spends its money on build details and matching design, while Bosch spends it on the things you can measure: noise, capacity and efficiency. Our editorial ratings, estimated from specs and owner and dealer coverage rather than lab tests, score both well on performance but give Bosch the clear edge on value.
Who should pick Cove vs Bosch
Pick Cove if the rest of your kitchen is Sub-Zero and Wolf and you want matching handles, one app for remote start and rinse-aid alerts, and one service family. It also suits buyers who load lots of stemware. Pick Bosch if you care most about noise, value and published capacity, or if your water is hard and you'd use the softener.
If neither feels right, the Miele G 7000 AutoDos splits the difference on price; see Cove vs Miele and Miele vs Bosch.
Cove vs Bosch dishwasher price, warranty and service
Here Cove earns part of its premium. It covers the dishwasher fully for 2 years parts and labor, then pumps, motors, control boards and baskets with limited 5-year parts coverage, plus a limited lifetime warranty on the stainless tub and door liner. Bosch covers 1 year parts and labor, electronics and racks parts-only through year 5, and lifetime rust-through on the tub and liner (parts only).
Neither brand lists a current promotion. A Cove is often bundled into a Sub-Zero/Wolf package, so ask your dealer to price it that way. Compare every model on the dishwashers hub.
Frequently asked questions
Is a Cove dishwasher worth the money?
It's worth it mainly as part of a Sub-Zero and Wolf kitchen. You get matching design, the same owner's app and a stronger warranty on key parts. As a standalone dishwasher, the Bosch Benchmark is quieter on paper and costs about $936 less at list, so Cove is harder to justify on specs alone.
Is Cove quieter than Bosch?
No. Cove rates the DW2451 at 41 dBA and Bosch rates the Benchmark at 39 dBA. Both are quiet enough for an open kitchen, and a 2 dBA difference is modest. If quiet is your top priority, the Bosch is the better choice by the specs, and it also costs less.
Who makes Cove dishwashers?
Cove is made by Sub-Zero Group, the same company behind Sub-Zero refrigeration and Wolf cooking. It was designed to complete Sub-Zero and Wolf kitchens, which is why it uses matching door kits and handles and runs on the same owner's app for remote start and alerts.
