How to Troubleshoot & Replace Bosch AP2802212 / 00298564 Dishwasher Drain Hose

I bought a new one and replaced the leaking part. 

2 day delivery of Bosch proprietary hose worked perfect. Back with clean dishes again. 

It was a saga. My son and I took apart the dishwasher without following the instructions. We later found on your YouTube posts. We found a loose hose and reconnected it, but when we put it back together it still leaked from the drain hose. We got the part (25 y.o. Machine, mind you) swapped it in, following the instructions this time) and — no more leak! Problem solved. 

I ORDERED THE HOSE FROM YOU AND HIRED A PLUMBER TO COME INSTALL IT. HE CAME YESTERDAY AND INSTALLED IT AND EVERYTHING IS AS GOOD AS NEW 

New hose 

Followed AppliancePartsPros.com video directions to purchase and replace drain hose. Worked like a charm. 

Ordered replacement hose from AppliancePartsPros.com. Replaced and reinstalled dishwasher. Problem solved. 

I followed the on line help you provided. 

Ordered Bosch drain hose. It was 6" shorter than the original drain hose. Had to go to hardware store and get 1' of heater hose to make the extension back to the disposal. 

I replaced it.
