More Whirlpool Filters
<blockquote>Older Whirlpools had automatic self-cleaning lint filters. It was a sort of rubber disk affair with internal hooks that caught lint during recirculation, and then expelled it during drains. Later Whirlpools shifted the lint filter to a plastic comb at the recirculation outlet above the tub. From the one I had in the 80's and 90's, it never seemed to catch much and it was a PITA to clean anyway.</blockquote>Manual-clean recirculating filters of the comb and cartridge type into the 80s were on lower-end belt-drive machines.
There were several designs on the self-clean/recirculating filter.
Later belt-drive machines went to a passive self-clean which was a disc/comb piece mounted under the basket. Water currents during agitation carried lint into the comb which was flushed during spin. This was also used on direct-drive machines, which by design couldn't have an active recirculating filter. It was later substituted to four simple "plug" filters, which were then eliminated completely. The parts diagram for the Catalyst that I recently refurbed showed the disc-style under-basket filter but upon disassembly I found it did not have a filter. Parts indicated substitution to the four plugs but the new basket that was sent did not have mounting holes for them.
