We have an older Kenmore Ultra Wash III that works relatively well, except that the water intake gets somehow blocked/stuck once the unit gets hot.
For a while, it used to get stuck in the rinse cycle, supposedly heating the water (according to the panel). It would get unstuck by itself and finish the cycle well, about 20 minutes later than expected.
Then it started getting stuck before taking the rinse water (it would go through the prewash and wash, then it would go into rinse, but not take any rinse water in). Dishes were cleaner but not rinsed.
Now it does the prewash with water, then goes on through the rest of the cycle without taking any more water for the wash or rinse. As such, dishes are really dirty.
Once the unit is hot, it will not take water even if you restart it with another prewash cycle. It needs to cool down for a while before it would take in any water.
The model number is 665.1694990, stock 16949. Any help would be much appreciated.
