Same thing here on a older Kenmore where it appears that initially the inlet port had a lot of calcium build up in it which pressurized it to the point it broke the bond between it and the tub. Since it appears to be PCV in nature I will try and use Oatley’s PVC pipe cement to see if that will work. If it works on 3" HD PVC Pipe I hope it will work on this and save having to buy a new dishwasher.
