Frigidaire LFID2422RF3B not cleaning dishes

This unit seems to run through all cycles and pumps water out but will not clean the dishes. I suspected the circulation pump and removed it, disassembled and lubricated but the problem still exists. The pump motor does run but apparently, it won’t produce enough pressure to operate and of the washer arms. The detergent packet usually lies on the bottom near the tub and is not even dissolved. Does this sound representative of a bad pump motor assy? The pump does run and is slightly nosier than it was when the machine was working properly. Just looking for a consensus agreement before I purchase a part I might not need. Also, does the hi-temp wash and start sequence for self-diagnostics work on this particular model? I tried that and all the LEDs illuminate and the motor runs for a minute or two then stops with no LEDs illuminated and does not restart a test sequence? Personal Emails are appreciated!

Many Thanks!
