Cleaning Issues

Food on dishes after the cycle is complete could a problem with water temperature. The water in your DU1100 model dishwasher must be at least 120 degrees Fahrenheit. Test the water temperature by running the hot water in your kitchen faucet, and place a waterproof thermometer under the water. If the water is too cold, increase the water temperature on your water heater. Check the water pressure with a water pressure gauge. If it's below 30 psi, contact your water company. Only use fresh, non-clumping dishwasher detergent. Old dishwasher detergent does not clean as well, and it suds a lot. Always properly load the dishwasher, and do not block the spray arm. Clean out any debris in the spray arm, pump filters and drain valve.
Not Running
-
If your dishwasher won't start, completely close the dishwasher door, and press "Start/Resume". Always select a cleaning cycle. Your dishwasher normally pauses between cleaning cycle. Verify that the water shutoff valve is in the "On" position and that water supply line is connected to the dishwasher. Reset your circuit if it's been tripped. Examine your fuses, and replace any ones with broken wires or black in color. Open up the dishwasher housing, and examine the door switch and wires. If any of these components are broken or burnt out, replace them.

Drying Issues
-
Always use a rinse aid to assist your DU1100 model with the drying cycle, and always use a heated dry setting. Unload the top rack first to avoid water from this racking spilling on the lower rack. Plastic-ware is normally wet after a drying cycle. Examine the heating element on the floor of the dishwasher. If it has burn spots or is cracked, you must replace it. Open up the main housing, and look at the drying fan. Change out the fan if it is not turning easily or if it has broken components.
Additional Issues
-
Your dishwasher normally makes grinding, buzzing or crunching noises. If it vibrates, level it with wood shims. If you hear a squealing sound, check the heater fan, and purchase a new one if it's rusted. Listen to the motor. If it makes a lot of noise, replace the bearings if worn out or the motor if defective. Your dishwasher may leak if the door is not completely closed or if you are using old detergent. Check the door gaskets, and replace them if they are worn or cracked. Examine the water inlet valve and hoses. If any of these components are broken or split, change them out. Tighten loose hose connections.
