Thermador dishwasher lineup at a glance
Choosing a Thermador dishwasher means deciding between three tiers, each sharing the same German engineering foundation but differing in drying technology, rack configuration, and smart features. All three are panel-ready and whisper-quiet — the decision comes down to how you value drying performance and cycle speed.
Star Sapphire — the flagship
The Star Sapphire is Thermador’s top dishwasher. CrystalDry zeolite-based drying delivers bone-dry results — even on plastics. StarSpeed completes a full wash in 20 minutes. The dedicated third-rack spray nozzle cleans items on the top level independently. Noise level: 39 dBA (near-silent). Home Connect Wi-Fi for remote monitoring.
Emerald — the sweet spot
The Emerald shares CrystalDry with the Star Sapphire but drops StarSpeed and the dedicated third-rack spray. It offers the same zeolite drying performance at a lower price point. Flexible third rack accommodates taller items in the middle rack below. Noise: 42 dBA. Home Connect included.
Sapphire — the entry point
The Sapphire uses condensation drying instead of CrystalDry — effective for ceramics and glass, but plastics may retain some moisture. Standard third rack without dedicated spray. Noise: 44 dBA. Home Connect included. The Sapphire is still a premium dishwasher — just without the zeolite drying advantage.
Which should you choose?
If you wash a lot of plastics or value bone-dry results: Star Sapphire or Emerald (CrystalDry). If speed matters: Star Sapphire (StarSpeed). If budget is the priority and you mostly wash ceramics/glass: Sapphire. All three share the same wash system, build quality, and panel-ready design.

- Use surge protectors — power fluctuations damage electronic control boards. A quality surge protector protects your investment
Making the right investment decision
Thermador appliances are premium investments designed for 15-20 years of service. When evaluating options, consider:
- Age — under 10 years: almost always repair. 10-15: evaluate cost. Over 15: consider replacement for major repairs
- Cost threshold — repair exceeding 50% of a new equivalent unit usually favors replacement
- Repair frequency — a single repair is normal. Multiple in 12 months suggests systemic aging
- Parts availability — discontinued models may have limited parts, extending repair timelines
- Energy efficiency — newer models may offer savings that offset part of replacement cost
Our technicians provide honest repair-vs-replace recommendations. Schedule service online for a diagnostic evaluation.
