When a dishwasher does not start, checking the power supply can save the cost of a service call. The shutoff is generally a switch near the sink or a plug into an outlet beneath the sink. The circuit feeding the dishwasher may also have a blown fuse or the switch may need to be reset. Checking these items and trying the dishwasher again is a simple first step; if no progress is made, a professional should be contacted to inspect the dishwasher.

If a dishwasher does not clean dishes well, consult the dishwasher's manual to see if the loads have too many dishes. If silverware has dropped through to the bottom of the dishwasher, it may be blocking the spray arm. Failure to scrape food off dishes can lead to incomplete cleaning as well. If the dishwasher does not have its own heating element, raising the temperature on the hot water heater to 140 degrees often makes a positive difference.

When a dishwasher has a leaky door, the likely culprit is the seal around the door. Check the condition of the gasket, replacing it if necessary. Cleaning the float switch can keep the dishwasher from overfilling; because of the wide variety of dishwasher models, consult the dishwasher's manual to find the process.
