I have a Kenmore Elite Dishwasher, model 665.16582200, that I bought
about 2 1/2 years ago that works correctly for some period of time, but
then starts buzzing the solenoid that lets the soap dispenser open. On
one or two occassions, it sounded like it was trying to inject rinse
agent again and again. If I open the door or turn it off for at least
thirty minutes, it works properly for a while, and then repeats the
solenoid buzzing.

These problems appear to be a failure of the electronic control panel
since there is no way the solenoid gets power unless the panel is doing
that, but I cannot get a straight answer from Sears about whether there
was an extended warranty (could this problem really be one that only I
ran into?) or whether the fact that I bought it with their gold card
extends the warranty.

This washer has always taken much longer than the timer control says,
eg, if the timer says 79 minutes, it will take 75 to 90 minutes to get
to the 30 minute dry cycle, which seems to come close to a correct
count, whether I use the 'smart wash' cycle or the standard one.

Any thoughts?
