Maytag quiet series 300 dishwasher won't start

Sounds like a thermal fuse that is a less than $20 part. remove the top 6 screws in the door that hold the plastic front panel on. Behind that is a circuit board and a white flat 1" square fuse with two wires going to it. make sure power is off at breaker. Test with an meter to see if any current is going thru. If not, that is most likely your problem, and just follow the fuse replacement kit instructions carefully, including putting the new wires on the new fuse like they say. Otherwise, the original wires going to the fuse will blow it too.

Should take about 20 minutes.

Maytag Quiet Series 300. The lights flash in sequence starting from the outside traveling inward. The timer counts backwards from 50 to 1. Then the sequence starts over. and continues over and over. I'm able to clear it when the time reaches 1 or 2. It stays off for a while (3-4 hours) then starts over. I can not clear the countdown until it reaches 1 or 2. After I clear it the dishwasher will work, but until then, no way. This happens with the door open or closed.

This is more of a tip than a solution as I am having a partial-draining problem and have discovered by accident how to have the Quiet Series 300 "drain only" (which is not an option on the control board and the manual doesn't seem to address this).
TIP 1:  The "drain-only" function can be activated by selecting "Rinse Only", pushing the "Start" button, and then pushing the "Start" button again (which cancels the start).  This activates the drain pump which will drain any remaining water.  
I think I might have a partial clog below which I have been able to access so far as I removed the top drain cover (3 --I think the term is star screws) and used a screw driver to take debris out from between the drain blades.  This improved things but didn't solve the problem. As of now, I just completely drain the machine by cancelling the "Rinse only" as described in TIP 1 above.   
TIP 2: If you don't have a star or hex screwdriver, you can pick up one very cheaply at a discount store (e.g., Odd Lots, Marcs, or even some Dollar Stores).  Check out their tool section.  I've bought a bunch of stuff, sure it is not the highest qualilty, but how often do you use most of your tools?  I bought the star-screwdriver set for about $1-2 and will probably use it 10-20 times in my lifetime. I bought it to change a bulb in out minivan and have now used it again.  In my cynical opinion, more and more companies are NOT using straight or phillips-head screws as a way to force many to use their repair services.  I'm not a professional, just a guy who's using the internet to feel his way around in the dark.
