Bosch's own owner-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 rather than any part replacement. Bosch 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 Bosch Most Bosch visits start at the dishwasher's filter cylinder and end at the compact laundry pair, with the refrigerator's coil and cartridge in between. ### Source Bosch US owner support, dishwasher error codes Confirmed on Bosch's own US owner-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 the filter need cleaning to avoid E22? Bosch's page calls for regular cleaning rather than giving one fixed interval; a household running frequent full loads benefits from checking it more often than a lighter-use kitchen. ### Can food debris cause E22 even with a fairly new appliance? Yes. The filter catches particles from every wash regardless of how new the unit is, so E22 can appear early if a household skips cleaning it in the first months. ### What if the filter looks clean but E22 keeps appearing? Check that it is fully reseated and locked in place, since a filter sitting slightly off can register the same way as a blocked one; if that does not clear it, book a visit. --- **[Read on the site: Bosch E22 — filter blocked | ApplianceMaintenance.center](https://appliancemaintenance.center/error-codes/bosch-e22/)** **[Book a visit with ApplianceMaintenance.center](https://appliancemaintenance.center/schedule/)**
