What is a Circulation Pump?

The circulation pump is the heart of your Whirlpool dishwasher, responsible for circulating hot water throughout the appliance. It ensures that the water reaches all corners of the dishwasher, effectively cleaning your dishes.

Several symptoms can indicate a faulty circulation pump in your Whirlpool dishwasher:

• Dishes are not cleaned properly
• Water remains in the dishwasher after a cycle
• Dishwasher makes unusual noises
• Dishwasher takes longer than usual to complete a cycle

How to Test a Whirlpool Dishwasher Circulation Pump

Materials Required:

• Multimeter
• Screwdriver

Safety Precautions:

• Unplug the dishwasher from the power outlet before starting any work.
• Shut off the water supply to the dishwasher.

Step 1: Access the Circulation Pump

Locate the circulation pump, which is typically situated at the bottom of the dishwasher. You may need to remove the lower access panel to access it.

Step 2: Disconnect the Circulation Pump

Disconnect the electrical wires and hoses connected to the circulation pump. Make sure to note the connections for reassembly later.

Step 3: Remove the Circulation Pump

Unscrew the bolts or screws holding the circulation pump in place. Carefully remove the pump from the dishwasher.

Step 4: Inspect the Circulation Pump

Visually inspect the circulation pump for any damage or blockages. Check the impeller for any debris or obstructions.

Step 5: Test the Circulation Pump with a Multimeter

Set the multimeter to the ohms setting. Touch one probe to each terminal of the circulation pump. A reading of 10-20 ohms indicates that the pump is working properly.
