Other causes of dishwasher leaks may require the help of a licensed technician. Here are some ideas for what you can do if your dishwasher is leaking.

Though not as common as the previous problems, you may run into an unresponsive dishwasher at some point. There are a few causes for a dishwasher that won’t start, some of which require the help of a professional. But before you schedule a service call, try the following troubleshooting tips:

• Turn off sleep mode: Ensure that your dishwasher wasn’t accidentally set to sleep mode. Open and shut the dishwasher door, then press the Start or Resume button to see if it will respond.

• Reset the dishwasher: Sometimes you can resolve this problem by simply unplugging the dishwasher and letting it sit for one minute before plugging it back in.

• Turn off control lock: Some models offer a control lock setting that helps to prevent buttons on the control panel from being accidentally pressed. Unlock the controls using the instructions provided in your product manual.

6. Detergent won't dispense

If your dishwasher dispenser isn’t functioning properly, detergent won’t be released during the wash cycle and your dishes won’t get clean. You can typically resolve this issue with the following tips:

• Remove caked-on detergent:Clean out the detergent dispenser of any caked-on detergent.

• Upgrade detergent storage:When powdered detergent is exposed to air it tends to clump and will not dissolve well, so be sure to store detergent in an air-tight container.

• Check water temperature:Detergent dissolves in warm water. Check that your water heater is functioning properly to allow dishwasher water to reach high enough temperatures during the wash cycle.

• Rearrange dishwasher racks:If the dishwasher racks are installed in a way that blocks the detergent dispenser, you need to rearrange them. Move the upper rack to a higher position to open a path for the detergent dispenser to open completely.
