Hi this is just coincidence:-)
Your dishwasher may be fine.
But keep me in the loop.
Please let me know when you run it next time how the dishes come out?
Another good thing to do that many people don't do is run your sink water til it is hot, should be atleast 160 degrees for proper operation.
Then run the Dishwasher , it will make a difference.
If you rate my service as good or better before you close this page, the system will allow me to schedule free follow ups with you so the Q & A will not cost you anything further and we can remain on here until this problem is solved;-)
I will stick with you on this.
Your answer has introduced another worry - if not from the dishwasher, then where did those brackets come from? I'll just have to take a look at the other kitchen appliances to try & figure it out!
LOL Trevor, I know the feeling!
Been there, they could have been from the original install. Sometimes the packaging contains them to hold the unit to the bottom of the box, actually this is common place these days:-)
I would think that's all they are.
How is the dish washer doing, with my advice?
Dishes any cleaner, residue wise?
Please let me know and rate my service at this point so I can set up the free follow ups in case you need me further for this at no additional cost to you.
Have a nice day Trevor:-)
