Saga of the dishwasher

One of my daily tasks which I do everyday without fail or my kitchen goes to hell, is loading the dishwasher every night after my daughter goes to sleep. I may not empty the sink but I do load the dishwasher so that the sink is not overflowing the next day.

A couple of weeks ago, after the dishwasher was done, I noticed there was water still at the bottom of the dishwasher and the dishes had some small deposits on them like they weren't fully clean. I ran the dishwasher again - it still had water. Realizing we didn't have a plunger at home, my husband bought a plunger from the store and used it and after a few tries, the dishwasher started running again. This again happened a week ago  on Monday and we repeated the same. This time, I called our home warranty guys from Sensible Home Warranty and complained. They said they'd call back to file a claim. I called again on Tuesday, same thing - they said they'd call back.

Then last week on Friday, the same thing happened and this time the plunger did not work. I tried to call the home warranty folks many times that weekend and would get the strangest message when I tried to file a claim - it said "invalid extension". I couldn't figure out what happened and thought maybe they're closed over the weekend (though their website said 24/7) or their system was screwed up. Anyway, I washed vessels by hand the next few days, hoping to keep the sink from getting overwhelmed.

Monday morning, I go to the website which I still had open on my laptop and refreshed the page. The website says that they are shut down and thanks for your support. I was completely taken aback. We just lost $700 of our 2-year warranty and I still had a dishwasher that wasn't working.

I then called a plumber who said it's not a plumbing issue (which was strange - he told me that without even coming down to look at it) and then I called an appliance repair person who agreed to come out the next day. He came out yesterday, looked at it, said it was a plumbing issue. He fixed it - said that it looks like most probably, there was a piece of glass which he showed me which was stuck in the pipe from the dishwasher to the sink drain pipe. Once it was dislodged, the dishwasher started working just fine.

He charged me $120 for fixing the issue, which was reasonable.

Now, the next question is, should we get another home warranty or should we just forget the whole thing?
