Thermador's own support page names the filter as the area where food particles get caught, and describes E22 as that filter being blocked, with regular cleaning as the fix. Thermador home appliance display · also shown as E-22 What to do when E22 shows on the home appliance ### Kind of code Filters A filter has reached the end of its life or is clogged enough for the appliance to notice: a refrigerator water cartridge past its gallons or months, a hood's grease or charcoal filter loaded with residue, a dish-care filter packed with food, a washer inlet filter choked with grit. The fix is a clean or a new filter of the right part number, fitted with the appliance unplugged and the water closed where there is one, then the reminder reset. ### Usually leads to Water filter and descaling service Fresh filters in dispensers and ice makers, and scale cleared from steam ovens, ice makers and dish care machines. ### Shows up as Dishes Coming Out Gritty or Spotted: Filter, Spray Arms and Rinse Aid Dishes coming out gritty are plates and glasses with sandy specks, dried food, a white film or spots after a full cycle, often worse on the upper rack or in one corner. ### Make Thermador A Thermador kitchen asks for upkeep in several places at once: star-shaped burner ports, steam oven scale, a column unit's coil and the hood's baffle filters. ### Source Thermador US support, dishwasher error codes Confirmed on Thermador's own US support error-code page for its dish care line. ## Before you book, in this order.

Remove the filter from the base of the tub and wash it under running water with mild soap and a soft brush. If it comes back, it needs a visit. ### How often does a Thermador filter need cleaning? Thermador calls for regular cleaning without a fixed number; a busy household running full loads daily benefits from checking it more often than a lighter-use kitchen. ### Can a small item cause E22 even with a fairly new appliance? Yes. A glass fragment, bone or label caught in the filter mesh can trigger it regardless of how new the unit is, so it is worth checking directly rather than assuming a part has worn out. ### What if E22 keeps returning after cleaning? Confirm the filter is fully reseated and locked; if it still returns, book a visit so the wash pump behind it can be checked. --- **[Read on the site: Thermador E22 — filter blocked | ApplianceMaintenance.center](https://appliancemaintenance.center/error-codes/thermador-e22/)** **[Book a visit with ApplianceMaintenance.center](https://appliancemaintenance.center/schedule/)**
