Your dishwasher failed the other day. It made a big noise, came to a full stop and its fuse was blown. There also came some smell of fire from it. Without any more inspection I made the quick decision that a repair would take too much time and too much money. Then I bought a used dishwasher via Internet for very little money.
Today I checked the rotating arm of that new item in our household, and was not at all surprised to see that some of the holes in its rotating arms was completely blocked by debris.
I did a Google search and found this:

It is a time consuming job, but there is no need for a drill. If you find that your dishes are not as clean as they used to be, some dishwasher maintenance may be needed.
