In the past 2-3 cycles, my dishwasher has done an underwhelming job of cleaning things, and I'd appreciate some tips on trying to improve it, based on:
- It's a simple Maytag model from around 1991.
- It's generally always worked fine.
- All of a sudden, both halves of the dispenser cup have had a hard rock of undissolved detergent (Cascade powder, same stuff we've always used, and it's not a brand new box either) caked into them at the end of a cycle. The undissolved stuff occupies maybe a third of the cup, and yes, I dig it out before running more dishes through.
- I found that maybe four of the holes on the dishwasher's arm (out of around 20 holes total) were clogged. I pulled a three-inch-long strip of cellophane from one hole, semi-unplugged a second hole using a fork tine, and will go after the other ones with tweezers unless someone can offer a better tip.
- I am running the dishwashwer right now with an empty load, and nothing in it but a lot of vinegar.
Any other tips or suggestions?
