We recently discovered that our tub wasn't filling with hot water. The cold works fine, but when we pick a mix or hot-water wash it fills slowly and only with cold. I can feel the hot water line when it's running and it's warm so that tells me there must be some water flow, but it's not making it to the tub.

A year or so ago I changed the rubber hoses over to braided. I specifically picked hoses that didn't have the safety pressure valve. After that time it seemed like the tub filled more slowly at random times. I frankly ignored it until my wife mentioned that there wasn't any hot water on the hot-wash and sure enough that's probably what I was hearing.

Here's some troubleshooting I've attempted so far.[LIST=1]

Checked the flow rate from the hoses: very good.

Checked the hoses were connected correctly: they were.

Checked the screens for debris: a little bit, but nothing significant.

Tested the resistance of the coils: 1,000 ohms on the hot side, 1,100 ohms on the cold side.[/LIST]At this point I'm tempted to replace the mixing valve, but one of the problems I'm running into is finding parts for my model number of washer. I have a hunch that there's a parent model number and that mine is specific to the electronic control panel model.

So I could use the following help:[LIST=1]

Help finding an equivalent model number so I can start tracking down parts.[/LIST] Thanks in advance!
