The other day I went into my basement and there was a puddle of water on the floor. It turned out that my front loading clothes washer was leaking. The drum was full of water to the point where it was dripping out of the open door. Yuk!
It appears that one of the washer's internal inlet valves has a slow drip leak. I ended up closing the door and running a "rinse" cycle to pump out the water. Happily, it seems like the very first thing the washer does is drain the drum. (A better design might have the washer pump out water on its own when it unexpectedly hits a high-water mark, but maybe there is a good reason not to do so.)
Then I ran some loads of laundry because, hey, I still have to do laundry and no slow leak is going to stop laundry.
Happily, affordable replacement washer inlet valves are available, and they are relatively easy to replace. But there's bad news: I don't like to fix non-broken things, so I need to identify which valve (hot or cold) is leaky. To complicate things, I have not been able to repeat this leaky valve event, so I'm waiting until it happens again.
Once I figure out which valve is unreliable, I'll document its replacement here.
