This provides better quality cleaning but reduces the life of the filter, which will have to be replaced more frequently. The use of inadequate detergents can damage the filter.

• Check the filter body for tears.

• If necessary, clean the filter compartment rubber gasket (D, Fig. 11) along its perimeter and check it for integrity. If necessary, replace it.

• Assemble the components in the reverse order of disassembly, and note the following:

Install the filter (C, Fig. 11) with the wire gauze (B, Fig. 12) turned towards the machine front side.
