The Micro Switch is an OEM part for LG dishwashers. It plays a crucial role in detecting when the door is securely closed prior to starting a cycle. This important safety feature prevents accidental exposure to hot water, detergent, and chemicals. 

Causes of a bad micro switch include degradation from years of repeated use, debris interfering with mechanisms, or damage from attempts to force or slam the dishwasher door closed.

Symptoms of a bad micro switch include:

• Cycles failing to start despite a closed door
• Hot water or steam visible escaping when running 
• The dishwasher not detecting the closed door position
• Error codes displayed related to door position sensors

This OEM LG part is also compatible with Sears/Kenmore. Replacing only when truly faulty helps ensure safe and reliable dishwasher function.
 

This main PCB is the central electronics module that routes power and coordinates your appliance's operations. Replacing a failed board can restore stable performance and proper response from the display, sensors, motors, pumps, and other components.

The Pump Motor Assembly is an OEM component specifically designed for LG dishwashers. It houses both the wash and drain pump motors integrated within a singular assembly. 

These motors work together to efficiently circulate water through spray arms during wash cycles for optimized cleaning performance. They also help drain dirty water at the end of each cycle, ensuring dishes are thoroughly rinsed.  

Symptoms of a bad pump motor assembly include:

• Inadequate or incomplete wash and rinse performances
• Water failing to drain fully after cycles
• Leaks occurring due to ineffective pumps   
• Abnormal sounds from the motor during the operation

Causes can include normal wear over time, failures in motor electronic components, or damage from foreign debris. 

Replacing the pump motor assembly with this genuine OEM LG part restores optimized wash and rinse functions. It is also compatible with Sears/Kenmore dishwashers.
