There is no dishwasher brand we would tell you to avoid outright, because every major manufacturer builds both durable machines and fragile ones. What does predict trouble is configuration. The models that reach our Boston dispatch board most often share three traits: integrated electronics with proprietary diagnostics, so a fault that would be a twenty-minute test on a simpler machine requires brand-specific equipment; plastic tubs with heating elements glued or welded in place, so a failed element means a tub-level repair rather than a part swap; and weak parts support, where a control board is discontinued within five or six years of the model being retired.
The hardest category of all is unbranded and builder-grade units installed in new condo developments, where parts frequently become unavailable within two years of purchase.
The Three Traits That Actually Predict Failure
- Proprietary integrated electronics. Feature-heavy machines with touch panels, WiFi, and app control add boards and a display that can disable an otherwise healthy appliance. Worse, some platforms will not report a fault code without manufacturer software, which limits who can service them and what it costs.
- Non-serviceable tub components. On several plastic-tub platforms the heating element is bonded into the tub. A $60 element becomes a $280 to $520 repair, or the machine is written off.
- Short parts support. This is the trait that decides whether year eight is a repair or a replacement, and it is the hardest to research before buying. Ask the retailer how long parts are stocked after a model is discontinued.
None of these are brand-wide. You can buy a simple, serviceable machine or a fragile one from most manufacturers on the same showroom floor.

Read this as one company's service calls in one metropolitan area, not a national reliability index. It reflects what we are asked to fix, which is informative but is not a controlled study.
Three Questions to Ask Before You Buy
- How long are parts stocked after this model is discontinued? This single answer matters more than any review score.
- Is the tub stainless, and is the heating element a separate serviceable part? Both answers should be yes.
- Can a local independent service it, or only factory-authorized? Restricted parts channels raise the cost of ownership for the life of the machine.
