The first thing to check is the water level in the tank. The water level should come up over top of the outer edge of the metal filter. Start a Normal cycle, and then after filling stops, open the door and check the level. The first two fills are not full timer interval fills, but the 3rd fill is a full 90 seconds, so the water level after that fill should be higher than the first two, and definitely over the top of the outer edge of the metal filter. If it isn't, then you might need a new fill valve.
This could also explain why the detergent doors aren't opening all the time. The timer sends power to the motor for one timer interval through each bi-metal, and the current passing through them causes them to heat and bend, which opens the door. If the water level in the tank isn't high enough, the motor doesn't have to work as hard to pump the water around, so not as much current gets pulled through the bi-metals, and they don't heat enough to bend and open the door. |

After the cycle you should not have more than 1/4" of water in the bottom of the sump area.
When fully filled for a wash or rinse you should have around 1/2" over the entire bottom of the DW all the way into the corners of the tank, as mentioned before most common problem if you are not getting enough water is a bad inlet valve.
