Will Not Run
I had the exact same problem. The tech came by and suggested to run the diagnostic cycle to clear up the error. Nice guy didn't charge for the time. He said Whrilpool has a poor software design.
Problem - LED blinks 7 times when the temperature doesn't come up to the degree F required for the wash. This may happen if someone took a shower minutes before starting the dishwasher.
The Tech said, Whirlpool should have allowed a straight forward reset by the customer (instead of disabling the machine for a tech to come by and fix the minor issue).
Here is the solution.
Solution - (is pretty much the same to clear up the other software glitches as well)
Try "resetting" the control board by running the diagnostic cycle. The cycle completes in 15 minutes.
The details are in the service manual. The manual can be found hidden behind the tow plate (at the very bottom front of the washer).
The diagnostic cycle may tell you the problem. It also helps clear up some of the software gltiches.
It is easy to run the diagnostic cycle.
Just the buttons in the following sequence. The sequence should be complete within 6 sec.
heated dry -> Normal -> heated dry -> Normal
This will trigger diagnostic cycle of 19 intervals. Pay special attention to the intervals 18, 17, 9, 6, 4.
Interval 18 - displays your controller module number (should be letter 'd' followed by number 0 or 1 or 2 or something. Note that down for future reference.
Interval 17 displays 'software generation number' Note that down for future reference.
Then wait until you reach interval 9. --- clean LED turns on - then an open or shorted thermister is detected.
-- Sanitized LED turns on - then the washer detected greater than 100 deg F temperature
-- Soaking/sensing LED should NOT come on (unless food soil is present).
Interval 4 -- Soaking/sensing LED should come on
Let the cycle complete and then try running the normal wash. Hopefully the possible glitches are cleared by now and you should have no problem.
If this doesn't work, time to call the expert tech.
