Quarterly tasks
Dishwasher: Clean drain filter, inspect spray arms, run cleaning cycle. Refrigerator: Wipe door gaskets, check drain pan, verify temperature with thermometer. Range: Clean Star Burner ports with a pin, inspect igniter glow speed. Oven: Check door seal, wipe interior with baking soda paste. Cooktop: Clean glass surface with dedicated cleaner, check gas connections. Wine cooler: Check temperature accuracy, wipe gasket, inspect for unusual vibration.
Annual tasks
Refrigerator: Clean condenser coils, replace water filter, test door gasket (paper-slip test). Range/Cooktop: Have gas connections inspected with a leak detector, calibrate oven temperature. Dishwasher: Inspect drain hose for cracks, check door hinge tension (panel-ready models). Vent hood: Check ductwork for grease buildup, test damper operation, clean or replace charcoal filter. Wine cooler: Replace carbon filter, clean condenser coils, check compressor mount vibration. Ice maker: Descale evaporator plate, replace water filter, sanitize ice bin.
Post-summer (before holiday cooking season)
This is the ideal time for a full kitchen audit. Test all burners and oven cavities before Thanksgiving demands peak performance. Schedule any needed repairs well before the holidays — technician availability drops significantly in November and December. Schedule your pre-season checkup early.

- Keep your owners manual accessible — it contains model-specific maintenance schedules and troubleshooting trees. Digital versions are available on the Thermador official site

- Use surge protectors — power fluctuations damage electronic control boards. A quality surge protector protects your investment
Preventive maintenance saves money
Regular maintenance is the most cost-effective way to extend your Thermador dishwasher lifespan and avoid expensive emergency repairs.
- Annual professional inspection — catches wear before failure. Critical for gas connections, sealed systems, and electronics
- Filter replacements on schedule — water, air, and carbon filters have finite lifespans. Running past service life degrades performance
- Gasket and seal checks — door gaskets and hose connections develop micro-leaks over time. Quarterly visual inspection prevents damage
- Cleaning as maintenance — buildup of grease, food debris, mineral scale, and dust directly contributes to component failure
