FIELD: household appliances.

SUBSTANCE: group of inventions relates to domestic appliance (100) with pump (105) for pumping of liquid. Pump (105) comprises pump housing (111), suction chamber (107) comprising suction pipe (109) for connection with suction line to transfer fluid, and filter pump with filter element for filtration of contaminants from liquid. Suction chamber (107) comprises opening (113) for filter insertion. Pump filter includes filter cover (117) made with possibility of tightly closing hole (113) in closed position and its opening in open position. Cover (117) in closed position is fixed on housing (111) by means of first connection (125) with geometrical closure. Cover (117) in closed position is fixed on housing (111) by means of second connection with force closure. To switch cover (117) from closed position to open position and opening of hole (113) there is necessity for disconnection of first connection (125) with geometrical closure and second connection with force closure.

EFFECT: inventions are aimed at excluding accidental transfer of filter cover from closed position to open position and, accordingly, accidental opening of hole for filter insertion.
