We've just managed to dishwasher the same load 3 times.
I loaded it last night, as per usual. I *thought* I ran it.
This morning, I went to grab a coffee cup out of it, and noticed a plastic Tupperware tub in immediate view was obviously still dirty.
'Bollocks' says I.
Must have forgotten to run it last night. Sometimes happens.
Shoves in a tab and lets it run.
Gets home this evening, to find it running again.
Mrs. F tells me she found the contents dirty, assumes I've forgotten to run it and has run it this evening.
WTF?
The Tupperware tub is *still* dirty.
Closer inspection reveals it's 2 tubs, stacked together when they were dirty.
The dishwasher can't get at the stuff jammed between the 2 tubs.
The load has now been run 3 times, because a casual inspection makes it look like it's a dirty load.
