For immediate access to the correct replacement elements, locate the pump assembly beneath the detergent tank–this area houses the high-pressure seal, unloader valve, and ceramic pistons (part codes 6.930-038, 6.930-040, and 6.930-052). Verify compatibility by cross-referencing these numbers with the official service documentation, not third-party diagrams, as tolerances differ by ±0.2mm for piston clearance.
