The impeller on the wash pump is worn out or the disposer screen is obstructed. Disassemble as needed to investigate the cause.

Hi


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.

The clean light keeps blinking and won't run new cycle

Whirlpool & Kitchen-Aid
Tall Tub Dishwashers
PROBLEM: STOPPED RUNNING, WILL NOT START AND CLEAN LED BLINKS 7 TIMES, THEN REPEATS (WATER HEATING FAULT)
Control is programmed to stop running and not allow any further
cycles if it detects a water heating problem (no temperature
increase detected in heated Main Wash cycle or in 3 consecutive
cycles on the latest software version). Control blinks the Clean
LED 7 times repeatedly and disables the Start/Resume key until
cleared.
Running Diagnostics clears the control and allows it
to operate again. The water heating condition
must be corrected or the control will stop
running again. See potential causes below.
Check If…
Heater circuit problem:
♦ Open heater.
♦ Wire disconnected, open connection or component
in heater circuit.
♦ Faulty heater drive circuit on control.
Then…
1. Check operation of heater in Diagnostics cycle.
2. Unplug dishwasher or disconnect power.
3. Check resistance of heater and all components
and connections in the water heating circuit or heat
dry circuit.
Door switch not making contact consistently:
♦ Misaligned door latch assembly (which can be
aggravated by high door closure force keeping
strike plate from fully seating).
♦ Faulty door switch (high resistance).
♦ Loose or missing installation anchor screws,
causing tank to shift in cut-out.
NOTE: Neutral switch on plastic tub models is only in series with
the heater; other loads are not affected.
1. Unplug dishwasher or disconnect power.
2. Measure resistance of door switch contacts while
checking mechanical operation of latch assembly.
Confirm switches not loose from assembly. Check
strike plate and door closure.
Wash pump not pumping water past the heater efficiently.
• Foreign object in pump
• Excessive foaming
• Clogged pump screen or broken chopper screen
• Loose electrical connection in motor circuit
See Tech Sheet “WASH PUMP WILL NOT PUMP”.
Lack of water to heat. (Unit not filling properly)
• Insufficient water supply pressure
• Fill valve screen blocked or valve not opening fully
• Loose electrical connection on Fill Valve.
• Float switch obstructed or functioning abnormally
See Tech Sheet “WILL NOT FILL OR LOW
WATER”.
Diagnostic Key Dance:
Heat Dry - Normal - Heat Dry - Normal or
High Temp - Air Dry - High Temp - Air Dry

Clean light is blinking. dishwasher won't turn on

it is a problem with the heating cycle.Dishwasher “Clean” Light Blinks 7 Times The electronic control looks for a temp. rise of 2° - 4° F.
If no temp rise, the control assumes a heater fault and blinks the clean LED 7x.
Check the heater circuit, water fill, wash pump operation, and neutral side door
switch.
Run a Diagnostic Cycle to reset the control.
REPLACING THE CONTROL WILL NOT RESOLVE THE CONDITION.
All Electronic Controls
S.O.P. – Standard Operating Procedure Whenever an electronic control is suspected
to be the cause of a product failure: before replacing the control, disconnect and then
reconnect all of the wiring harness connectors to ensure proper electrical contact.
I hope this helps.

Clean light keeps flashing and won't let me start

A clean indicator that flashes/blinks 7 times and then repeats, indicates a problem in the dishwasher which should be investigated and not just the control 'reset'! That is why the control will not let the dishwasher start once such a condition is detected.
If the dishwasher's eletronic control doesn't detect a water temperature increase during the main wash cycle, that symptom can occur. No water temperature increase could be caused by a problem in the heater element, its in-line thermostat, the related wiring or a problem in the electronic control.
It is also possible just the washer not spraying properly (possibly from blockage in the filter or problem in the pump), the dishwasher not filling sufficiently or draining prematurely or even a problem in the door latching mechanism's switch(es) could cause it.
*Some actual investigation should be undertaken to isolate and correct the cause of the symptom.*
Once corrected, the error display may have to be cleared from the control manually. That can usually be done by putting the unit into diagnostic mode by pressing the key sequence 'Heated Dry, Normal, Heated Dry, Normal' and then pressing cancel.

Dishwasher almost fixed but won't pump water

Could be the motor is stuck. This is a common problem in dishwashers. With the power turned off, open the front kick panel and turn the motor a couple of times by hand. Then turn on the power and run the drain cycle to see if the motor drains properly.
