Dishwasher panel would light up and go through cycle but not start washing

I used the diagnostic tool to determine which part I needed and ordered it. After receiving the part very quickly I took off the front panel easily enough and removed the old part as per video instructions. I realized it did not look exactly the same. I wasted a good bit of time calling both the parts co. and Fridgidaire to find out that there had been numerous problems with the old part so a new part was designed differently and therefore did not look the same but should work. Reviewing the video again I installed it and Voila the dishwasher was once again operational. The big mistake is I took the complete front part of the dishwasher off which took a while to reinstall. All in all the experience was a good one. Saved me money and God knows these days every penny counts.
