The door must be closed within four seconds of pressing the Start button. Open the door and either close the door and press Start (front controls) or press Start and close the door within four seconds (top controls).
Why is my LG LDTH797 leaking in front?
Leaking in front of the appliance can be caused by the dishwasher not being leveled properly. Verify the appliance is level from side to side and from front to back. Also, check if the wrong detergent was used. If excessive sudsing is causing the leak, allow the foam to subside for 24 hours, then clean the inside of the tub with milk.
Why does water remain in the tub of my LG LDTH797 after the cycle is complete?
If water remains in the tub after the cycle, the drain hose may be kinked or clogged. Adjust the hose to remove any kinks, or clear any blockages present.
Why is there noise during operation of my LG Dishwasher?
Some level of noise is normal during dishwasher operation. However, if the noise seems excessive, check that the dishwasher is level and adjust the leveling feet if needed. Also, make sure the nozzle arm isn't knocking against the dishes; if it is, reposition the dishes.
What to do if my LG LDTH797 Dishwasher will not operate?
If your dishwasher isn't operating, make sure that you have pressed the Start button and that the door is completely closed and latched. Check that the power supply or power supply line is properly connected. Also, verify that a fuse isn't blown or a circuit breaker tripped, and ensure that the Control Lock is deactivated.
How to remove cloudy, white film on dishes after washing in my LG LDTH797?
The cloudy film is usually caused by minerals in the water reacting with the dishwasher detergent. First, be certain not to use too much detergent. Refer to Adding Detergent to the Dispenser section for recommended detergent amounts. You can also add an extra rinse to the cycle. If you have hard water, it may be necessary to add a performance booster that addresses the hard water condition.
How to improve drying results in my LG LDTH797?
Poor drying results can occur for a few reasons. First, run the hot water tap in the sink before starting a wash cycle to ensure cool water is purged from the hot water lines. Using the High Temp. setting can also help. If you're using a rinse aid, adjust the amount to optimize performance. If washing plastic items in a Normal cycle, select the Dry Boost or Night Dry option. Finally, allow the dishwasher to completely finish the dry cycle before opening the door. Note that plastic and nonstick surfaces are harder to dry because water tends to bead rather than sheet off.
