Bosch E22 is a blocked filter. Food particles have clogged the filter, and Bosch says the filter needs cleaning regularly. The checks are to remove the filter, wash it under running water with mild soap and a soft brush, and reinstall it using the owner's manual. E22 does not ask you to open the drain pump. The pump cover under the filter is the E25 job: a blocked drain pump, or a cover that is loose or missing. If E22 comes back after the filter is clean, use Bosch's E22 guide or contact Bosch Customer Support.
