LG Dishwasher stops mid-cycle
If your LG dishwasher stops mid-cycle, the most likely problem is the water inlet valve. When this valve fails or gets clogged, the dishwasher can drain the sump area and then quit before the next fill, which is a common reason an LG dishwasher stops during cycle or shuts off mid-cycle. Next, check the door latch, because a weak or damaged latch can let the door switch tell the control board to stop the cycle early. It is also worth checking for fault codes on the display, since LG dishwashers will often point you toward the failed system when the dishwasher cycle stops before finished. After that, look at the control board, which powers the dishwasher’s electrical components and can cause the unit to stop mid-cycle if it is not sending power correctly. Less often, a bad circulation pump or pump and motor assembly can be the cause, especially if the dishwasher fills but you hear only a humming sound or the wash impeller is not moving water through the wash arms.

01 - LG Dishwasher Water Inlet Valve
The water inlet valve opens to allow water to enter the dishwasher. If the water valve fails, the dishwasher will stop in mid-cycle after the remaining water in the sump area has drained prior to the fill cycle. The water inlet valve coil can be tested for electrical continuity to help determine if the part is faulty. The valve could also be clogged. A clogged valve can not be cleaned and should be replaced.

02 - LG Dishwasher Door Latch
The dishwasher door needs to be properly latched for the appliance to work. If the latch is faulty, the door switch could signal the control board to stop the dishwasher in mid-cycle. Inspect the door latch for any damage and replace if necessary.

03 - Check Fault Codes
If the dishwasher stop mid-cycle, a fault code will usually be displayed to help diagnose the issue. Refer to the owner's manual or do an on-line search to find out more information regarding what the fault code means.

04 - LG Dishwasher Control Board
A dishwasher's control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to all of the electrical components which can cause the dishwasher to stop mid-cycle.

05 - LG Dishwasher Circulation Pump
The circulation pump uses a motor and impeller to force water up through the wash arms. If the circulation pump is defective, the dishes won’t be cleaned properly. If the motor isn’t making any noise or is just making a humming sound after the dishwasher has filled, the motor may be burned out. First, ensure that power is getting to the motor. Second, to ensure that the impeller can turn, check the pump housing for debris. If power is getting to the motor and the pump is clear of debris, the motor might need to be replaced. Be aware that the circulation pump may be challenging to replace, although many do-it-yourselfers ha...

06 - LG Dishwasher Pump and Motor Assembly
The motor drives an impeller to force water up through the wash arms. If the motor is defective, the pump impeller is broken, or some part of the pump is clogged, dishes won’t be cleaned properly. Make sure that power is getting to the circulation pump and motor. If power is getting to the pump and motor assembly but it still won’t run, replace the pump and motor assembly.
