To reset your Samsung DMR78AHB dishwasher, press and hold the 'Start/Reset' button for about 3 seconds until the indicator lights turn off. This will reset the dishwasher's control board.
Check the drain hose for clogs or kinks. Ensure the garbage disposal cap is removed if recently installed. Clean the filter and check for debris in the drain pump.
Remove the lower dish rack, locate the filter at the bottom of the dishwasher, twist it counterclockwise, and pull it out. Rinse under running water to remove debris.
Noises can be caused by items blocking the spray arm or debris in the pump. Ensure dishes are properly loaded and check for obstructions.
Inspect the door gasket for damage or debris, ensure the dishwasher is level, and check for loose or cracked hoses.
Regularly clean the filter, wipe down the door gasket, inspect spray arms for clogs, and run an empty cycle with vinegar to remove buildup.
Open the rinse aid dispenser cap, adjust the dial to the desired setting (1-6), and close the cap. Higher settings dispense more rinse aid.
The “HE” error code indicates a heating error. It may require checking the heating element and ensuring the water temperature is adequate.
Ensure the rinse aid dispenser is filled, use a high-temperature wash cycle, and consider using the sanitize option if available.
A flashing light can indicate an error or a cycle pause. Refer to the manual for specific light patterns and meanings, and reset the dishwasher if necessary.
