Self-Cleaning Kenmore with Filter Light
Yes the light was on when ever the washer agitate solenoid was energized, the light was a great way to show off this Great Feature. The only time that the light was a lie was when the suds water was being returned to the machine on SS models, as the light was on but the returning suds water was not being filtered as it was came back into the washer. The true back-wash SCFs were first installed on the 1958 LKMs and continued till the last belt drive KMs and WPs on some models [ only suds-saver machines on most models built after 1981 ]. This was by far the most effective filtering EVER used on any automatic washer, far surpassing the well known GE FF machines.
There was only one other TL washer that had a filter as effective as these WP built washers and it was a GE machine, it was GEs first automatic washer and Robert has the only one in existence. It is his 1947 GE that my brother Jeff and I rescued over 35 years ago and I traded it to Robert for a Westinghouse Combo that I gave to Jeff.
