My Whirlpool dishwasher 2007 is 9 years old. The soap dispenser became old and was no longer shutting. So I ordered a new part and replaced it. Now when I run a cycle when it get to the part where it the dispenser opens it makes a load noise. The dispenser opens how it is supposed to but the noise is loud and scary. Is the new part bad and need another replacement. I have taken it out twice and put it back in hoping that the problem was it was not installed right. It didn't help.
