Roper Dishwasher WU4300B0 Not drying dishes properly

The Rubber Washer is an OEM part for Whirlpool dishwashers. This washer plays a role in ensuring a leak-proof seal at various connection points within the dishwasher, such as at the water inlet valve or hose connections. Its primary function is to prevent water from leaking out of the dishwasher during operation, thereby ensuring efficient and safe use of the appliance. 

Over time, rubber washers can deteriorate due to the constant exposure to water and chemicals found in dishwasher detergents. 

Symptoms of a bad Rubber Washer in a dishwasher include:

• Visible signs of wear or damage to the washer, such as cracks, brittleness, or deformation.
• Water leaking from the dishwasher, particularly around areas where hoses and valves connect.
• A decrease in dishwasher performance due to water not being contained properly during cycles.

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

This base heater assembly restores the oven's lower heating function in select convection microwaves. It delivers bottom radiant heat for baking and crisping so the unit can preheat properly and brown foods evenly.

• Supplies bottom heat during convection, bake, or crisp cycles
• Works with the control and temperature sensor to reach and maintain set temperature
• Common symptoms of a failed heater may include no heat in convection mode, very long preheat, or poor browning/crisping
• Visible damage to the element or tripping a circuit breaker may also indicate a shorted heater

• Disconnect power before servicing. Microwaves contain high-voltage components that can retain a charge even when unplugged
• Allow the unit to cool completely; access typically requires removing the outer cover or lowering an over-the-range unit
• Note wire locations and routing before removal; transfer any brackets, shields, or screws from the original assembly
• Route wires exactly as original and avoid pinching; confirm clearances before reassembly and test a convection preheat

This thermal fuse protects your appliance by opening the circuit if temperatures climb beyond a safe limit, helping prevent wiring or control damage. When it blows, the unit may lose all power or stop mid-cycle. What it does:

• Cuts power when overheating is detected to protect internal components
• Helps prevent damage from shorted heaters, motors, or wiring faults
• Common symptoms: no power, won't start, shuts off during operation, no lights/display
• A blown fuse reads open (no continuity) and must be replaced—it is not resettable

• 1 thermal fuse

• Disconnect power before servicing to avoid electrical shock
• Access the fuse location per your model's service information; note wire orientation and mounting
• Replace one-for-one; do not bypass or up-rate the fuse. Identify and correct the overheating cause before restoring power.
