Thanks again, Dbrock.
Thanks for the answer on not being able to advance the cycle in non-diagnostic mode.
I should have been more clear. The dishwasher does not stop operation at 97 and 44, it runs and runs and runs at that time and does not advance to 96 or 43 and on down.
Here are a couple more things I have tried or gleaned since my last post:
- During a Normal/Heated Dry cycle when it hangs at 97 minutes, I am able to open the door and add hot water (180+ degrees) heated on the stove and the cycle is able to continue its countdown. (I think I have deduced that on the Normal/Heated Dry cycle, the dishwasher stays at 97 (wash) and 44 (rinse) until the water is heated to a target temperature). I am able to manually help it through an entire wash cycle (that cleans as normal) in this manner.
- I went back and tried the same process at Step 9 in the diagnostic cycle. Adding the hot water gets the Sanitized light to come on, which I believe indicates the thermister is operating correctly. This makes sense of why I can add heated water at 97 and 44 and get the cycle to continue.
To me, this isolates two problems still:
1) There is not enough water in the tub during the 97 and 44 minute heating periods.
2) If there is enough water in the tub (if I add it) there may also be a problem with the dishwasher heating the water to the target temperature.
Hopefully if I accomplish the first, the machine can do its job and accomplish the second.
- I removed the inlet valve and did the best I could to clean the filter screen (thimble shaped that I did not remove completely). That did not improve things.
- I think the heating element is working because it is definitely hot when I am adding extra water. From what I have read, it seems like the heating element is either working or not working. Is this true, or as the element starts to go bad, does it not heat up as much as it is supposed to?
My current guess is that the water inlet valve is bad and I have a replacement part on the way. If I can get the washer to have the appropriate amount of water during the heating period at 97, maybe the heating element can do its job to reach the target temp and advance. Side question, how does the washer know how much water to add to the tub? Does it fill until the float valve stops it? Does it fill for a preset time regardless of the flow rate? If this is the case, could low house water pressure result in not getting enough water to the tub?
Otherwise, if the water inlet valve is not the issue, maybe I have a siphoning issue and even though the machine tries to fill adequately at the beginning of the wash cycle, it does not stay in there. I have tried to adjust the drain hose as much as I can to address potential siphoning issues, so if it is that, I don't know what else I can do.
I'm still not sure why the lower washer arm does not spin freely all the time. It seems to get stuck in a certain position. Is there a way to lubricate something so that it spins more freely? Is the rotational velocity of the arm based on the water pressure that the pump provides? Could this be a factor of needing more water in the tub during washing?
