Symptom	Solution	Click images to enlarge Old Style Dishwasher Door Switch Old Style New Style Door Switches Ditto Components New Style Dishwasher
Dishwasher will not complete a cycle.	Check the timer for proper operation Check timer switch leads to timer motor Compare timer with sequence chart on wiring diagram Make sure all leads to the timer are secure and tight Some models have a thermostat. Check to make sure it is in contact with the tub.
Dishwasher will not drain.	Check for hose kinks or food plugging drain hose. Check pump impeller for damage Check pump motor for reversing during the pump out Make sure the dishwasher is pausing between the wash and drain cycles letting the pump/motor reverse for the drain cycle. Check timer for not letting the dishwasher pause. If you have recently installed a new garbage disposal, check knock-out plug at connection. Check the check valve and drain hose for debris. Check that the water inlet valve isn't seeping fresh water into the dishwasher when off. (if yes, replace the inlet valve).
Dishwasher will not fill with water	Check float switch or float. Check water supply valve. There should be 110 volts to the coil. Water inlet valves get plugged with mineral build up. Replace water inlet valve on dishwasher as needed. Check the timer to make sure the contacts are closed for water fill valve. Look at wiring diagram for contact numbers
Dishwasher will not get the dishes clean / Soap Not rinsed out of the dispenser / Not spraying on the top rack	Check pump recirculation., Listen, see if it sounds like it is spraying the water around with enough pressure. Check water level when the fill cycle has completed. Should be barely touching, or just under the float. If not, replace the water inlet valve. Check the spray arm for splits or leaks. Check the water temperature. Should be 125 to 160 F. Check to make sure dishwasher is draining after each cycle. There should only be a little water in the bottom of the tub. Make sure the dishes are loaded properly, or dishwasher is not overloaded. Try a different detergent. We like powder cascade the best. Some liquid-gels will bubble and a pump cannot pump bubbles.
Dishwasher will not run at all.	Check connections from power cord to terminal block. (we see this a lot) Check door switch for action and continuity (we see this a lot) Check power at outlet. Should read 110 volts. Check the timer for power
Water leaks from the bottom of the dishwasher.	Check air gap for mineral deposits. This will cause the water to spray out of the air inlet. Check for cracks in the tub. Check the float switch seal. Check the heater element where it enters the tub. There are gaskets that sometimes leaks. Check the hose clamps. Check the hoses for leaks. Check the pump motor assembly for leaks Check the door seals for leakage check the soap dispenser for leakage Check that the water inlet valve isn't seeping fresh water into the dishwasher when off. (if yes, replace the inlet valve).
Water leaks from the door.	Check corner seals and bottom dam seal Check door seal Check for loose or bent door latch Check for over filling. This could be from float switch. The water should never or barely reach float. The float switch is for overflow. Water inlet valve isn't shutting off and letting water seep into the tub when not energized. With dishwasher turned off check inside of dishwasher at water inlet hold on side of the tub. Make sure water isn't slowly seeping into the tub due to a bad water inlet valve. Check the spray arm for a split. If water sprays directly at the bottom of door, it will create a leak. Check that the water inlet valve isn't seeping fresh water into the dishwasher when off. (if yes, replace the inlet valve).
