Common Causes Of Heating Issues
If your Kenmore dishwasher isn’t heating water, several factors might be at play. Understanding these common causes can help you identify and address the issue effectively.
Faulty Heating Element
A common issue lies with the heating element. This component warms the water during the wash cycle. If it’s broken, the dishwasher can’t heat water, leading to ineffective cleaning. To check the heating element, follow these steps:
- Unplug the Dishwasher: Always prioritize safety when working with appliances.
- Access the Heating Element: Remove the lower spray arm and disassemble as needed to reach the heating element.
- Inspect for Damage: Look for signs of burns or fractures. If it appears damaged, replacing the heating element typically resolves the issue.
Malfunctioning Thermostat
The thermostat regulates the temperature of the water. If it malfunctions, the dishwasher might fail to heat water adequately. Here’s how to examine the thermostat:
- Locate the Thermostat: Check your user manual to find its position, usually near the heating element.
- Test the Thermostat: Use a multimeter to check for continuity. If it doesn’t show continuity, you’ll need to replace it to restore proper function.
Clogged Spray Arms
Clogged spray arms can restrict water flow, affecting how the appliance heats water. When the spray arms are blocked, the water may not circulate effectively during the cleaning cycle. Follow these steps to clean them:
- Remove the Spray Arms: Most Kenmore models allow easy removal by unscrewing or snapping off.
- Clean the Nozzles: Use a toothpick or small brush to clear debris from any clogged holes.
- Rinse Under Water: Ensure all debris is washed away, enabling optimal spray.
By addressing these common causes, you can often resolve heating issues with your Kenmore dishwasher, leading to cleaner dishes and a more effective washing experience.
Troubleshooting Steps
If your Kenmore dishwasher isn’t heating water, follow these troubleshooting steps to identify and resolve the issue.
Checking Electrical Connections
Check all electrical connections to ensure proper operation.
- Inspect the power cord for any signs of damage or fraying.
- Examine the outlet where the dishwasher plugs in. Ensure it’s functioning by testing it with another appliance.
- Verify the circuit breaker has not tripped. If it has, reset it and see if the dishwasher powers on.
Testing The Heating Element
Testing the heating element is essential to determine if it’s functioning.
- Unplug the dishwasher for safety.
- Locate the heating element at the bottom of the unit. Check for visible signs of damage, such as burns or breaks.
- Use a multimeter to test the heating element’s continuity. Set the multimeter to the ohms setting, and place the probes on the heating element terminals. A reading between 10-30 ohms indicates a functioning element. If the reading is infinite, replace the heating element.
Inspecting Water Supply
Inspecting the water supply is crucial, as it can directly impact heating.
- Check the water inlet valve. Ensure it’s fully open and free from obstructions.
- Examine the hoses for kinks or clogs. Clear any blockages to allow proper water flow.
- Test the water temperature. Run hot water at the sink and ensure it reaches at least 120°F before the dishwasher starts. If the water isn’t hot enough, your dishwasher may struggle to heat it further.
Following these steps can help you pinpoint and resolve the heating issue in your Kenmore dishwasher, leading to cleaner dishes.
