Hmv3021/U02 Parts

This diode is a single-direction semiconductor used on appliance control boards to direct current and protect circuitry from reverse voltage. Replacing a faulty diode restores proper electrical flow and helps prevent further board damage. What it does:

• Allows current to flow in one direction to support proper circuit operation
• Helps protect control electronics from reverse-voltage damage
• Common symptom: appliance fails to power or control board behaves intermittently
• Common symptom: blown fuse or visible damage at the diode location

• Disconnect power (unplug or shut off breaker) before servicing to avoid shock or injury
• Observe basic ESD (electrostatic discharge) precautions when handling control board components
• Replace only with the exact part number or verified equivalent; secure solder or connector connections per OEM guidance

A replacement circulation pump motor that restores water movement in the dishwasher's wash system for proper cleaning and rinsing. Installs in the pump assembly to replace a worn or failed motor and stop noisy or non-operating pumps. What it does:

• Drives the dishwasher's water circulation/pump assembly so wash arms receive proper water flow.
• Common symptom: little or no water spray during the wash cycle or poor cleaning performance.
• Common symptom: loud grinding, humming, or the pump not starting when the cycle runs.
• Works as the rotating motor portion of the pump; requires correct pump housing and seals for a leak-free installation.

• One motor

• Disconnect power and turn off water supply before beginning repair.
• Inspect pump housing, gaskets, and impeller during replacement; replace worn seals to prevent leaks.
• Handle the motor and electrical connections carefully; ensure connectors are fully seated and secured.
• After installation, restore power and run a short cycle to check for proper operation and leaks.

This filter module is the dishwasher's primary filter assembly that traps food debris and helps prevent drains from clogging, maintaining wash performance and protecting the pump. Designed to fit into the lower tub area and sit under the spray arm. What it does:

• Captures and holds food particles and solids to keep wash water cleaner
• Helps prevent pump and drain clogs that can cause poor draining or noisy operation
• Directs filtered water back into the wash for consistent cleaning
• Supports proper circulation by sealing the filter area and maintaining water flow

• Disconnect power and turn off the water supply before starting any work.
• Remove lower dish rack to access the filter area; handle the module carefully to avoid damaging tabs or seals.
• Align and press the module into place until it clicks; ensure any retaining clips are engaged.
• Clean the surrounding area and run a short cycle to check for leaks and proper operation.

This grill grid is the metal rack that supports and elevates food inside your appliance for grilling/broiling. It restores a stable, level surface and helps promote even heat exposure for better browning and crisping.

• Elevates food closer to the heat source to improve browning
• Allows heat and air to circulate around food for more even results
• Provides a sturdy, level platform for cookware or food
• Replace if bent, unstable, corroded, or missing

• Disconnect power and allow the appliance to cool before handling the grid
• Position the grid on the designated supports/turntable per your model's instructions; ensure it is level and not touching cavity walls
• Use only in cooking modes approved by your owner's manual
• Clean with non-abrasive methods and dry completely before reinstalling

This high-voltage capacitor supplies and stabilizes voltage for the appliance control/ignition circuit, helping the system operate reliably and start as intended. It replaces a worn or failed capacitor to restore proper electrical performance. What it does:

• Stores and releases electrical energy to support the control/ignition circuit during startup and operation
• Helps maintain stable voltage to sensitive control components
• Commonly replaced when the appliance fails to start, has intermittent control issues, or shows electrical arcing/sparking
• Matches the original form and connections for a direct replacement

• One high-voltage capacitor
