Dishwasher Wiring Problem

Dishwasher Wiring Problem

About 1 1/2 yrs ago we had our kitchen remodeled. Last summer I removed the access panel from the dishwasher and found the wire nut on the neutral wire melted and the same thing but to a lesser extent on the hot wire. I thought maybe the plumber didn't get a good contact when twisting the wires and arcing had occurred. I removed the damaged wire, made the connections and placed new wire nuts on. I checks again today and the wire nuts are slightly melted but less than before.
The dishwasher is about 6 years old, runs fine and is on the same dedicated 20 amp circuit that it's always been on.
Any ideas on what may be causing this?
Thanks.

Well for one, thats a cheap, ****ty wire nut in the picture so I'm not surprised.
Get some good nuts and I'd recommend a good pre twist. Make some good contact. As suggested, also check the neutral at the panel if your competent enough to avoid frying yourself. May be a tad loose. But I'd say its just a poor job on connections.

Thanks for the reply. Visually the neutral appeared firmly screwed to the bus bar but I assume I need to take a screw driver to it to be sure. I'm also assuming the panel should be shut off to do this.
The wire nuts were Buchanan. Is there another brand you woudl suggest?
The wire coming from the diswasher is stranded which makes it (at least for me) a bit difficult to be sure I've got a good twist with the romex.
Thanks again for your help.

I use ideal wing wire nuts.
The issue most likely stems from the fact that it is stranded to solid and does take some experience to properly terminate. I usually trim my solid wire about 1/4" and my stranded a shade longer , put them equal at the bottoms and twist my nut on. You will know you have a good connection when it gets tight and then give the stranded a tug and make sure it holds.
