Question about Dishwashers
The clean light keeps blinking and the machine does not run.
Any help will be appreciated.
You, my friend, have the dreaded 'blinking clean light.' This means that the electronic control has detected that for three consecutive cycles,
1. the heater hasn't come on
2. the water hasn't come into the dishwasher
2.5. the water came in, but wasn't spraying around inside.
3. the heater came on, but the temperature probe did not detect a 3 F degree rise in temp in a certain alotted time. (Is the water supply unusually cold?)
Originally, this fault code could happen if any of these happened just once. Now they program the elec control to wait until the 3rd consecutive ocurrence.
First, let's clear that fault code.
Since you did not mention any unusual sounds, I will assume the water is filling and spraying around inside.
Press 'heated dry', 'normal', 'heated dry', 'normal'. This activated the test cycle, and clears any fault codes. After 10 seconds, press 'cancel'. Open the door and carefully see if the heating element came on. (It should be hot.)
If it did come on, it's an intermittent problem, and could be related to the door switch. Some earlier models would allow the dishwasher to run with only one of the two contacts closed, but the heater would not come on. Be careful to close the door tight each time. They have redesigned the switch (or is it the door latch?) to ensure both contacts get closed.
If the heater did not come on, then you might need (in order of higest to lowest probability) a heater, a heater thermostat, or the electronic control board (heater relay.)
I haven't ever seen a failed temperature sensor, though it is theoretically possible.
You can continue using your dishwasher until it is repaired. Though, you may have to reset the fault code 2-3 times a week.

Tips for a great answer:
If clean light is blinking then it may be an
issue with heater circuit, door switch or wash pump, please reset the power to
the dishwasher. After, 5 minutes check if you are still getting the same error.
If yes, then it is a water heating fault. To resolve this error try pressing
this reset sequence-- Heat Dry - Normal - Heat Dry - Normal or High Temp - Air
Dry - High Temp - Air Dry or Hi Temp Scrub, energy saver dry, Hi Temp Scrub,
energy saver dry or High Temp Wash-Heated Dry-High Temp Wash-Heated Dry .
Now let the unit run for 2-3 minutes and then you press the Cancel/Drain button
and allow it to completely drain and reset. If this doesn't work then it's an
issue with the wash pump not pumping the water past the heater efficiently or
due to lack of water to heat. Please make sure that heater is not open
circuited and is heating the water efficiently. You'll have to check the heater
using a multimeter; the meter should read between 3000 to 3300 ohms (Use
multimeter on Rx1 ohm setting). If heater is fine then make sure water pressure
is optimum and fill valve is working fine. Hope this helps... Please post
back if you need more information.
