Thermador builds a professional-style kitchen line but leaves laundry to sister brands, so a maintenance account here covers cooking, ventilation, dishwashing and refrigeration only. Its dishwasher error-code page shares BSH's heat-pump architecture with Bosch, which means the same filter and descale routine keeps a Thermador dishwasher out of trouble, while its hoods and refrigeration columns run on their own filter and cleaning schedule.

We take on Thermador ranges, cooktops, ovens and steam ovens, ventilation hoods, dishwashers, and built-in refrigeration and wine columns; Thermador does not sell washers or dryers, so laundry calls for this brand go to the sister site. ### A heat pump wash system that scales Thermador's own dishwasher support page lists limescale in the heat pump as its own code, with a descaler as the fix rather than a part. Hard-water homes see this sooner, and a standing descale routine keeps it from recurring. ### A filter the owner clears first The same support page treats a blocked wash filter as an owner-cleared step: remove it, rinse it, refit it. A visit checks this on a schedule so it never becomes the reason a cycle fails. ### Water filters on a calendar, not a code Thermador recommends changing a refrigeration water filter about every six months, or when the appliance signals it, rather than waiting for an error message. Its own guidance ties this to taste and flow rather than to any single alert. ### Grease filters on their own clock Thermador's ventilation guidance calls for washing metal grease filters roughly every one to three months depending on use, since a hood's collection efficiency and safety both depend on that filter staying clear. Parts Thermador sells its own filters and descaling products through its accessories and parts pages, and a visit matches the model on the appliance's own rating plate before ordering either one. Repair or replace Thermador's maintenance calls are almost always solved with a filter rinse, a descale cycle or a grease-filter wash; nothing documented here points toward a replace-versus-repair decision.

No. Thermador's own product pages cover cooking, ventilation, dishwashing and refrigeration; a household with a Thermador kitchen and a different brand's laundry set gets that laundry work from the sister site instead. ### How often should a Thermador water filter be changed? Thermador's own guidance is about every six months, or sooner if the unit's own alert or a change in taste says so first. A visit checks the filter housing and the model number before ordering a replacement. ### Why is my Thermador appliance asking to be descaled? Thermador names this limescale collecting in the heat pump that warms the wash water, which is a normal hard-water effect rather than a failing part. A descaler run on the maker's schedule usually clears it. ### How often do grease filters need washing? Thermador recommends roughly every one to three months depending on how much cooking the hood sees. Filters left longer collect grease that both blocks airflow and becomes a fire risk. --- **[Read on the site: Thermador Appliance Maintenance](https://appliancemaintenance.center/brands/thermador/)** **[Book a visit with ApplianceMaintenance.center](https://appliancemaintenance.center/schedule/)**
