Heating coil went bad

I had to remove the dishwasher from under the counter. I then had to unscrew (from the bottom) the bolts that held the heater in place. After that I ran into a problem of disconnecting the wires that ran to the heater. I did not want to "force" the wires off and I was unsure how exactly to remove them. I figured out that they are really hard to pull off but there are no clips holding them on, so you won't break anything off. Once I got the wires off, I was able to screw the nuts onto the new heater and put it back into place.
