(I'm sorry, but they have all been men, in my experience.)
I'm here to praise the internet, and give myself a pat on the back, for having solved a dishwasher problem last night. (I had no idea that solid material as small as a few lemon seeds, in the right spot, could result in a dishwasher leaving a substantial pool of grotty water inside.)
I think this is the third time in a couple of years where I've found the answer to an appliance problem on the internet (last night, courtesy of Youtube) and fixed it in light of the helpful information other people put up there.
One other thing - I was cynical about the use of bicarb soda and vinegar as a cleaning agent, but it did help my dishwasher problem last night in a very indirect way. I didn't have the right tool to get a screw out (it needed a hexagonal head, like an allen key, OK?) to remove a plastic cover over a part of the machine I wanted to get to. But I put in bicarb and a cup of vinegar in a general hope it would help de-grease things. The fizzing up of the mix was what actually floated upwards, out from beneath the cover I couldn't remove, the lemon seeds that I suspect were at the heart of the problem.
Fascinating, I'm sure you'll agree.
