Dissolves limescale, mineral deposits, and odor-causing residues from dishwasher tub and spray system. Use monthly to maintain peak cleaning performance.

A fixed electrical capacitor used to help appliance motors start and run smoothly. Replaces a failed capacitor to restore reliable motor performance and reduce abnormal motor behavior. What it does:

• Provides the startup/run electrical boost the motor needs to spin properly.
• Can stop or reduce motor humming, failure to start, or weak/irregular motor operation.
• Helps stabilize motor performance under load so cycles complete correctly.
• Reduces the chance of repeated motor stalls or overload trips when functioning properly.

• Disconnect power before accessing or replacing any electrical components.
• Discharge the old capacitor before removal to avoid shock risk.
• Observe polarity/terminal arrangement and secure connections per service manual.

This fixed ceramic capacitor replaces the original control/signal capacitor and helps stabilize voltage for reliable appliance operation. It restores proper electrical timing and reduces intermittent control or motor issues caused by a failing capacitor. What it does:

• Stabilizes voltage to control boards and motors to prevent erratic operation
• Helps restore proper start/stop timing for motors and compressors
• Can reduce symptoms like intermittent runs, unexpected shutdowns, or failure to start
• Supports consistent performance of electronic control circuits

• Disconnect power to the appliance before service to avoid shock
• Discharge any stored voltage in the old capacitor before handling
• Compare the replacement to the original for proper mounting and terminal fit

A fixed-film capacitor used in compatible LG appliances to stabilize voltage and filter electrical noise for reliable component operation. Replacing a worn capacitor helps restore consistent power delivery and reduce intermittent electrical faults. What it does:

• Stabilizes voltage and smooths electrical signals to control boards and motors
• Filters electrical noise that can cause erratic behavior or false error codes
• Helps components start and run more reliably when original capacitor fails
• Common symptoms: appliance won't start, humming, intermittent operation, or control errors

• One fixed-film capacitor as pictured

• Disconnect power before servicing and follow the appliance manufacturer's safety instructions
• Capacitors can store charge; discharge carefully
• Verify orientation and secure mounting against vibration when installing

This diode rectifier assembly converts incoming AC to DC to supply the appliance's control electronics, restoring proper voltage flow for reliable operation. It's a direct replacement part used in the control/power section of the appliance. What it does:

• Converts alternating current (AC) to direct current (DC) for the control board and related electronics
• Helps stabilize supply voltage so controls, displays, and relays operate correctly
• A faulty rectifier can cause intermittent power, blank displays, or failure to start
• Works as part of the power-delivery system; replacement may resolve power-related symptoms

• One diode rectifier assembly

• Disconnect power (unplug or shut off circuit breaker) before servicing to avoid shock
• Handle electronic components carefully and avoid static discharge; use anti-static precautions if available
• Inspect surrounding wiring and connectors; replace any damaged wiring or loose connectors

A replacement switching diode used on appliance control and power boards to restore correct current steering and switching functions. Replacing a failed diode helps prevent erratic operation and allows the circuit to resume normal behavior. What it does:

• Directs or blocks current in switching circuits to control power flow
• Protects sensitive components by preventing reverse voltage on the board
• Commonly fails open or shorted, which can cause intermittent operation or loss of function
• Works as a small, discrete part on control or power assemblies

• Disconnect power and unplug the appliance before servicing
• Discharge any capacitors on the board to avoid shock
• Observe diode polarity when installing (match orientation exactly)

This switching diode routes and controls current in the appliance's control or power circuitry to enable correct switching behavior and protect components. Replacing a failing diode restores proper circuit switching and helps prevent intermittent faults. What it does:

• Directs current flow for switching functions in control or power boards
• Protects circuits from unintended backflow or voltage spikes
• Helps prevent intermittent operation, erratic switching, or control board malfunctions
• Used where rapid switching or high-speed rectification is required

• One switching diode as shown

• High-level board-level replacement — handle the circuit board and components with care
• Disconnect power and fully discharge capacitors before service to avoid shock
• Observe ESD precautions and use proper tools; soldering/desoldering skills may be required
