In Arizona even if you had your foot on the brake to take off immediately as soon as the DW hurriedly dumped a couple bags down the toilet I doubt you'd make the turn out of the driveway before the ice is melted. So IMO add a couple gallons of water (probably more than 2 melted bags of ice) & a good healthy squirt of Dawn will do just as good after a good black tank flushing.
Most likely the ice nor the Dawn will help the sensors for more a tank full or 2. So if the sensors are the reason, save the ice & the Dawn, it's a waste of both.
