If your Kenmore washer is taking too long to wash, starts slowly, or has a washer cycle too long, check the water supply first. Make sure both the hot and cold water supply valves are fully open. A closed or partially open valve can prevent the washer from filling or delay the start of the wash cycle. If the water supply is normal, a defective heating element may be causing the washing machine to take too long by failing to raise the water temperature. Disconnect power and test the heating element for continuity with a multimeter. If it fails, replace it. Another possible cause is a faulty water inlet valve. Check the household water pressure, then inspect and clean the inlet valve screens where the hoses connect. If the washer fills slowly or does not fill properly after cleaning, replace the water inlet valve. These are the most likely causes of a Kenmore washing machine taking too long, although exact parts vary by model. Enter your model number to find the exact replacement heating element or water inlet valve for your specific washing machine.
01 - Water supply valve turned off
Confirm that both the hot and cold water supply valves are fully open. If the valves are closed or partially open the washer won't fill or will take longer to start the wash cycle.
Highly Likely
02 - Kenmore Washing Machine Heating Element
Many washers use a heating element to raise the temperature of the water entering the tub. A defective element may cause the washer to take too long to clean its load. You can use a multimeter to test the heating element for electrical continuity. If the element tests negative for continuity, you'll know the heating element is faulty and will need to be replaced.

The water inlet valve opens to allow water to enter the washing machine. If the water inlet valve is defective, the wash may fill slowly or not fill at all. The water inlet valve requires sufficient water pressure to function properly. First, check the water pressure to determine that it is adequate. If the water pressure is adequate, try cleaning the screens inside the water inlet valve hose connection ports. If the washer still fills slowly, replace the water inlet valve.
