Set up and use Thermador Home Connect — connect dishwashers, ovens, refrigerators, and cooktops to the app for remote monitoring and control.

What is Home Connect?

Home Connect is Thermador’s smart home platform that connects compatible appliances to your smartphone. Monitor cycle status on your dishwasher, adjust oven temperature remotely, get alerts when the refrigerator door is left open, and track energy usage across all connected Thermador appliances. The app is available for iOS and Android.

Compatible Thermador appliances

Most current Thermador appliances include Home Connect Wi-Fi: Star Sapphire and Emerald dishwashers, Freedom Column refrigerators and freezers, wall ovens (Masterpiece and Professional), and select cooktops. Check your model’s spec sheet for the Home Connect logo.

Setup process

1. Download the Home Connect app. 2. Create an account. 3. On the appliance, enter the Wi-Fi setup mode (varies by appliance — check the manual). 4. In the app, select “Add Appliance” and follow the on-screen pairing wizard. 5. Connect to your home Wi-Fi network through the app. 6. The appliance will appear in your dashboard once connected.

Useful features

Dishwasher: Start/stop cycles remotely, get notification when cycle ends, monitor rinse aid level. Oven: Preheat remotely before you get home, monitor cooking progress, get alerts when target temperature is reached. Refrigerator: Door-open alerts, temperature monitoring, filter replacement reminders. General: Energy monitoring, troubleshooting assistance, service scheduling.

Troubleshooting connection issues

Appliance must be within Wi-Fi range (not behind thick walls or metal). 2.4 GHz network required (most appliances don’t support 5 GHz). If connection drops frequently, check for Wi-Fi interference from other appliances. Factory reset the appliance’s Wi-Fi module and re-pair if issues persist.

Frequently asked questions about Thermador dishwashers
How loud are Thermador dishwashers?
Star Sapphire models operate at 39 dBA — quieter than a library. Emerald at 42 dBA, Sapphire at 44 dBA. All are among the quietest dishwashers available.
What is CrystalDry and do I need it?
CrystalDry uses natural zeolite minerals to absorb moisture and generate heat during the drying cycle. It produces bone-dry results — even on plastics — without a heated dry element. If you regularly wash plastic containers, it’s a significant upgrade over condensation drying.
Are Thermador dishwashers panel-ready?
Yes — all Thermador dishwashers accept custom cabinetry panels for a seamless kitchen look. Panel weight must stay within specifications to prevent hinge and latch wear.
How often should I clean the drain filter?
Monthly. This prevents most E24/E25 drain error codes and maintains wash performance.
Can I use any detergent?
Use quality dishwasher detergent tablets — never liquid dish soap, which creates excessive suds and can damage the pump.

Important notes for Thermador dishwasher owners

  • Always use genuine OEM parts — aftermarket components may fit but can compromise performance, safety, and warranty coverage on Thermador appliances
  • Never ignore error codes — Thermador codes are diagnostic aids designed to prevent small issues from becoming major failures. Address them promptly
  • Keep your owners manual accessible — it contains model-specific maintenance schedules and troubleshooting trees. Digital versions are available on the Thermador official site
  • Document issues before calling — note error codes, symptoms, when they started, and patterns. This helps the technician diagnose faster
  • Use surge protectors — power fluctuations damage electronic control boards. A quality surge protector protects your investment

When DIY troubleshooting is not enough

Some Thermador dishwasher issues can be resolved with the steps in this guide. However, call a certified technician immediately if you encounter:

  1. Gas smell (gas models) — turn off the appliance, open windows, leave the house, call from outside
  2. Burning smell or smoke — disconnect power immediately. Do not use until inspected
  3. Electrical sparking — turn off at the circuit breaker. Wiring or component failure
  4. Water leaking inside walls — shut off supply and call to prevent water damage
  5. Error codes that return after power reset — persistent codes indicate real component failure
  6. Sealed system issues — compressor, refrigerant work requires EPA-certified technicians
