Disassembly:
• Disconnect electric power.
• Drain pump.
• Disconnect piping.
• Remove the 4 bolts (1) and take off the casing (2).
• Remove motor cap (8) and insert a screwdriver. Unscrew the impeller (4) in a counter-clockwise direction.
• Slip the rotating seal (5) from shaft (7) of seal plate/motor assembly.

Reassembly:
• Clean all parts thoroughly before reassembly. Use liquid soap on the rubber cup on the ceramic seat (6) and push it into the seal plate (9). Make sure
that the smooth surface of the ceramic seat faces outward.
• Assemble the seal plate (9) to the electric motor, being careful not to damage the ceramic seat (6).
