When using garbage disposal the water does not appear to get past the trap. I replaced trap and snaked out main line. No blockage. Tried resetting garbage disposal and turning center below with allen wrench. No success. Disconnected dishwasher and cleaned line – no blockage. Water standing in sink, but no apparent clogs anywhere. Disposal just turns/hums but does nothing. I disconnected the disposal from the sink to clean out. No blockages. Even if the motor were bad on disposal, wouldn’t water drain? Very stumped.
