Understanding Thermador appliance warranties — standard coverage, extended protection, what's included, and what voids your warranty.

Thermador standard warranty coverage

All Thermador appliances come with a manufacturer warranty that covers defects in materials and workmanship. Coverage periods vary by product category and component — major components like compressors and sealed refrigeration systems typically have longer coverage than electrical parts. Check your specific model’s warranty documentation for exact terms.

What’s typically covered

Manufacturing defects, component failures under normal use, and electrical/mechanical issues that arise from standard operation. Genuine OEM replacement parts and authorized labor to install them. Warranty service must be performed by a Thermador-authorized service provider to maintain coverage.

What’s NOT covered

Cosmetic damage (dents, scratches after delivery). Installation problems (incorrect wiring, gas connection, leveling). Normal wear items (gaskets, filters, light bulbs, knobs). Damage from power surges (use a surge protector). Damage from using non-OEM parts. Service calls where no defect is found. Issues caused by water quality (limescale, mineral damage).

Extended protection

Thermador and authorized dealers offer extended warranty programs that can extend coverage beyond the standard period. Consider extended protection for Freedom Column refrigeration (dual-compressor systems) and Pro Grand ranges (complex multi-system design) where repair costs can be significant.

Maintaining warranty validity

Use your appliances according to the manual. Don’t modify or repair with non-OEM parts. Keep your proof of purchase and installation records. Register your appliances with Thermador after installation. Have warranty service performed only by authorized providers — unauthorized repairs void the remaining warranty.

After warranty expires

Our certified Thermador repair technicians use the same genuine OEM parts and follow the same procedures as warranty service — the only difference is the cost. Schedule service anytime, warranty or not. We provide a 30-day labor warranty on all repairs.

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
