I purchased this Whirlpool dishwasher in Dec. 2014 from Home Depot. It has run flawlessly since then, up to 3 days ago. Now when the Start button is pressed all the lights come on and I hear the water filling in, but the upper and lower fans that distribute the water do not move. When I open the door I find the water settling in the bottom. When I press cancel, the pump is activated and the water in the bottom of the dishwasher is pumped out. I disconnected power to the dishwasher hoping to reset the control panel, but disconnecting the power did not change the situation. So the dishwasher now just sits there with all of the lights turned on with no activities. The lights that are on are for Normal Cycle, when I press that button again, the Normal Cycle light jumps to 1-Hr Wash and goes back to normal immediately. Cant get the Heavy Cycle or the Soak and Clean Cycle lights to light up. The other lights that are on are Heat Dry, High Temp, Sani Rinse. I cant change those lights by pressing the Options. By the way i removed the filter and cleaned it, but it was not clogged with debris

Could the control panel be the cause of this problem, or the motor that activates the water distribution fans. What part could be the major reason for this defect.

What have you tried so far?

Disconnected power to reset the control panel, that did not help. I removed the filter cup and found it nearly perfectly clean, but I cleaned a film of grease from the screen regardless.

Hello, to diagnose your issue you will need to run the unit through the diagnostic mode. It is only way to get the error code to find out what your problem is. See below steps to run through diagnostic.

  1. To invoke the Diagnostics Cycle, perform the following while in standby:
    ■ Press any 3 keys in the sequence 1-2-3-1-2-3-1-2-3 with no more than 1 second between key presses.
    ■ The Service Diagnostics Cycle will start when the door is closed.
    ■ To rapid advance 1 interval at a time, press the Start/Resume key.
    Rapid advance may skip sensor checks as some checks require
    2 complete intervals.

NOTE: While you are in the Diagnostic Cycle, the Start/Resume feature is turned off (for example, Auto Resume after door interrupts) and the Start/Resume key becomes an individual advance key.
■ Invoking Service Diagnostics clears all status and last run information from memory and restores defaults. It also forces the next cycle to be a sensor calibration cycle.
■ Drain and wash motors will pulsate on and off.
■ Last Ran cycles and options returned to default.
■ Last Ran Delay returns to the lowest delay increment.
■ Calibration cycle may force an extra rinse to occur prior to final rinse (to assure clear water), then calibrates the OWI and the fill amount during the final rinse.
■ Operating state returns to Standby upon completing or terminating the Service Diagnostics cycle

  1. Turn on all LEDs immediately upon receiving entry sequence (even if door is open) for 5 seconds as a display test. Turn off all LEDs for 1 second prior to reporting customer error history.

  2. Press Hi Temp key in this interval to clear customer error history.

  3. Thermistor (temperature sensor) checks:
    ■ Turn Clean LED on if thermistor is in its normal temperature range of 32°F–167°F (0°C–75°C).
    ■ Turn Sanitized LED on if Fill temperature is above 85°F (29°C).

  4. O.W.I. (Optical Soil Sensor) Checks:
    ■ Check OWI sensor for the presence of water during the 5-second pause in interval 16 and turn on the clean LED in interval 15 if water is detected.
    ■ Check OWI sensor for the presence of bulk soil during pause in interval 13 and turn on the clean LED in interval 12 if bulk soil is detected.
    ■ Drain until OWI sensor sees the presence of air or a maximum of 1:52 during interval 5 and turn on the clean LED in interval 4 if air is detected.

  5. Turn on Clean LED in this interval if dispenser current is detected in previous interval.
