A cookware washer includes a wash chamber, and a lower rack positioned within said wash chamber. The lower rack includes a substantially unobstructed bottom surface. (c) a piston slidably disposed in each of said piston bores and moveable in response to fluid pressure therein; (d) an actuator member extending externally of said body and attached to said piston for movement therewith; (e) an obturator disposed in said cavity and moveable for opening and closing with respect to said inlet port valving surface and said vent port valving surface for permitting and preventing flow between said inlet port and said valving cavity and between said cavity and said vent port; (f) a solenoid disposed with said body and having an armature operatively connected for, upon energization and de-energization, effecting said movement of said obturator, wherein said actuator member is adapted for operative contact with a valve de-actuation component of the engine, wherein said vent port is located vertically at a level higher than said plurality of piston bores for facilitating air bleed when the vent port is opened. 12. The operator defined in claim 11, wherein each of said piston bores includes a bleed passage communicating with said inlet port when said obturator is closed against said inlet valving surface. 13. The operator defined in claim 11, wherein each of said piston bores includes a bleed passage communicating with said inlet port. 14. The operator defined in claim 11, wherein each of said piston bores includes means biasing said piston in a direction to oppose the pressure forces of hydraulic fluid acting thereon. 15. The operator defined in claim 11, further comprising means biasing the obturator closed on said inlet valving surface. 16. A method of making an electro-hydraulic operator for use in engine valve de-actuation comprising: (a) forming a valve body having a valving cavity with an inlet port having a valving surface associated therewith and a vent port having a valving surface associated therewith; (b) forming a plurality of piston bores in said body and communicating each of said bores with said cavity; (c) disposing a piston in each of said bores for movement in response to fluid pressure therein; (d) connecting an actuator member to each of said pistons and extending said member externally of said bore for contacting an engine valve de-actuation component; (e) disposing an obturator in said cavity for movement between positions alternately opening and closing said inlet port valving surface and said vent port valving surface; (f) disposing a solenoid with said body and operatively connecting the solenoid armature for, upon energization and de-energization effecting said obturator movement; and, (g) forming a bleed passage in said body associated with each of said bores and communicating said bleed passage with said valving chamber. 17. The method defined in claim 16, wherein the step of forming a body includes locating the vent port vertically at a higher level than said piston bores. 18. The method defined in claim 16, wherein the step of disposing an obturator includes disposing a spherical member intermediate said inlet port valving surface and said outlet port valving surface. 19. The method defined in claim 16, wherein said step of forming a plurality of piston bores includes forming a plurality of bores disposed in spaced parallel arrangement. 20. The method defined in claim 16, wherein said step of disposing a piston in each of said bores includes biasing the piston in a direction to oppose the hydraulic fluid pressure forces acting thereon. 21. The method defined in claim 16, wherein said step of connecting an actuator member to each of said pistons includes attaching an end of an actuator arm to an end of the piston. 22. The method defined in claim 16, wherein said step of forming a plurality of piston bores includes forming at least two bores extending in opposing directions. 23. The method defined in claim 16, wherein said step of forming a plurality of piston bores includes forming three bores with the axes thereof lying in a common plane. 24. The method de
