Kenmore Dishwasher: sanitized light flashing
What is this symptom?
If your Kenmore dishwasher's sanitized light is flashing, it indicates that the sanitization process was not successfully completed, often due to low water temperature or an error in the cycle. This signal is a prompt to check for issues such as a faulty heating element, door latch problems, or control panel errors. Addressing these can restore proper function and ensure your dishes are sanitized effectively.
Important Tips for Kenmore Models
- On Kenmore dishwashers, a flashing Clean or Sanitize light often indicates the water did not reach the proper sanitized temperature, and may correspond to diagnostic error flash patterns. (Ready To DIY
Possible Causes
Water temperature too low to reach sanitization threshold
How to Identify: Hot water supply not sufficiently hot at start; water entering dishwasher feels cool; sanitized light flashes after cycle without completing sanitization. (Ready To DIY
Part: Water inlet heating/temperature system
Faulty heating element or thermostat
How to Identify: Dishwasher never heats to proper temperature; multimeter shows no continuity across heating element; sanitized light fails to engage.
Part: Heating element/thermostat
Door latch / interlock issues
How to Identify: Dishwasher cycle interrupts if door latch isn’t fully engaged; lights flash when door not detected as closed. (Appliance Parts Pros
Part: Door latch and interlock switch
Control board or control panel error
How to Identify: Multiple lights blink or error persists after checking mechanical causes; panel buttons behave inconsistently. (Appliance Parts Pros
Part: Main control board or user control/display board
DIY Solutions
Ensure hot water supply at cycle start
- Turn on the kitchen hot water faucet and let it run until the water is hot to touch.
- Start the dishwasher while hot water is flowing to ensure the initial fill uses hot water.
Reset dishwasher control panel
- Turn off power to the dishwasher at the circuit breaker or unplug it.
- Wait 1 minute, then restore power and try running a cycle.
