water came out of the vent is their something to clean
For model number WDT730HAMZ1
PartSelect logo
Hi Steve, thank you for contacting us. If water is coming out of the vent, it's likely because of a clog in the drain line. Use a long, flexible tool like a bottle brush or a piece of the cable to dislodge any clogs in the hose or the nipple at the disposal. If the issue persists, you may need to replace the drain hose, part number PS2358130. We hope this solves your problem!

Lost dishwasher brackets
I called an experienced plumber, who balanced and installed my new dishwasher properly, using the brackets I ordered from Parts Select, after an INEXPERIENCED plumber had tossed the factory-provided mounting brackets out with the shipping carton. Relief!

My filters had completely clogged up with hard deposits and food left on the dishes after running the dishwasher.
My filters had completely clogged up and had not cleaned my filters at all which was a no-no.I had lots of food left on the dishes after running my dishwasher, so I took bothp filters out and replaced them no tools required. I won’t be using powdered or liquid detergent for my dishwasher anymore only pods and promise to clean my filters once a month, so hopefully that’ll help keep them clean. Very easy replacement even for an old woman.
