Brand: Hello I have a kitchenmaid dishwasher model # KDFE104DBL5 I have replaced the following parts after chasing an initial failure of the diverter seal and water inlet valve:
New Main pump assembly
New Drain Pump
New Thermostat
New Control board
New Turbidity sensor
New Heating element
No codes are present after running diagnostics, the incoming water temp is well over 120 Degrees F , the heating element is active, the failure (blinking sanitize light) only occurs when a cycle using this feature is chosen. All other cycles run fine.
Any help is very much appreciated

Hi,

A copy:

Sanitized LED Blinks or Incomplete Sanitization Message at End of Cycle (Control Could Not Confirm Sanitization Achieved.)

Causes and checks:

  1. Door opened during
    final rinse or dry.
    Instruct customer.
  2. Incoming water
    under 84°F (29°C).
    1. Be sure dishwasher is connected to
    the hot water supply.
    2. Confirm temperature at sink
    (recommend 120°F [49°C]). Instruct
    customer to run water at sink before
    running dishwasher.
    3. Unplug dishwasher or disconnect
    power, check all connections, and
    measure resistance in Temperature
    Sensing circuit. Replace OWI if
    resistance is high.
  3. Line voltage too low to heat fast enough.
    Check power source. Confirm at least
    100 VAC.
  4. Heating problem.
  5. Refer to “Service Error Codes Table.” 7-1
  6. Intermittent door switch/latch connection.
    See same checks as for 5-1 error. Refer
    to “Service Error Codes Table.”
  7. Thermistor/OWI problem.
    Refer to “Service Error Codes Table.” 3-1
    3-2
  8. Air pressure surging
    in dishwasher due to
    washing with high suds
    causes brief opening of
    door switch contacts
    during final rinse.
    Refer to “Service Error Codes Table.” 6-3

I found this is the tech sheet. One should be inside your dishwasher.

Thanks for the reply I ended up removing the dishwasher and I re-seated all of the wire harness plugs. Then ran diagnostics no codes were present so I then ran a full wash cycle with sanitize and it worked great.

Glad that was all it was!

Another sanitize cycle was attempted however this one failed to sanitize. Given the extensive list of parts that have been replaced I have ordered a wiring harness.
