Load noise

My dishwasher is running fine except for every once and a while it will make a load "ca-chunk" sound. The last time it did it I looked and the dial was around the 6’oclock mark during the "light wash" step. Any ideas would be helpful.

Remove the bottom access panel and try to pinpoint the noise. Post the results.

One cooktop igniter stopped working, gas still working but no igniter.
