Black spots on dishes, water heater didn't work.

I looked at the cap,nozzle,which had the soft, black, rubber gasket on top. That gasket had begun to disintegrate over time and was leaving black specks on my dishes. I saw that it was simply a screw on installation and I did that myself in about 20 seconds. My husband and I removed the bottom plate at the front of the dishwasher and he quickly loosened the nuts on the heater element, we clipped the new one in, stabbed the connecters in place. He tightened the nuts, we replaced the cover, and my dishwasher works great! Thanks so much for having the parts on such an old appliance. We didn't want to replace the dishwasher, as it is a good one and worked great before. We want our appliances to work until we are ready to remodel our kitchen and upgrade all the appliances. My husband and I are very please with your availability of parts, the ease of your website, your diagrams are great, and the service was quick and reliable. We are extremely pleased. As a matter of fact when I finish writing this I'm gonna order another part for another appliance. Keep up the good work!
