Why replace the drain pump assembly?

The drain pump assembly is located underneath the dishwasher tub and connects to the sump at the base. When the drain pump is activated, it draws water from the sump and pumps it out through the drain hose during the drain cycle.

If the dishwasher isn’t fully draining and water remains at the bottom at the end of the wash cycle even after checking for clogs, the drain pump is likely broken and needs to be replaced.

What you need

• 5/8-inch open-end wrench
• Flat-blade screwdriver
• Phillips screwdriver
• 5/16-inch nut driver
• 1/4-inch socket wrench
• Replacement drain pump assembly (WD26X10048)
• Towels to catch any water drips

Safety precautions

When working on any appliance, always keep safety first to avoid personal injury or damage to the appliance or parts. Here are some safety tips to keep in mind:

• Always power off and unplug your dishwasher or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of electric shock.
• Shut off the hot water supply line.
• If the dishwasher has recently been used, give it plenty of time to cool down before working on it.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access dishwasher parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your dishwasher or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the dishwasher or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Consider wearing safety glasses and/or a dust mask when working with chemicals, dust or a large amount of debris to prevent irritation or injury.
