Whirlpool DP920PFGQ3 dishwasher Parts

On your Whirlpool dishwasher model DP920PFGQ3, the model number is printed on the rating label located just inside the door opening, typically along the left side of the inner frame. The same label usually lists the serial number as well.

• Open the dishwasher door fully.
• Look along the left inner edge of the tub frame (not the outer door panel).
• Check for a rectangular rating label with small printed text.
• Wipe the area with a damp cloth if the label is dusty or spotted.
• Write down the model number and serial number exactly as shown.

Most Whirlpool dishwasher rating labels include these fields:

We use the full model number to match the correct Whirlpool parts for your exact dishwasher configuration. Even small model variations can change fitment for items like a door seal, water inlet valve, or heating components.

Once you confirm the model number, you can confidently choose parts that fit DP920PFGQ3, such as the dishwasher door seal WPW10509257 if you’re addressing leaks around the door.

Dishwasher parts are typically named by what they do: filling, washing, heating, draining, drying, and sealing. On your Whirlpool DP920PFGQ3 dishwasher, you will commonly see parts such as the water inlet valve, spray arms, heater, racks, and door seal.

• Water inlet valve: lets water into the tub at the start of a cycle
• Spray arms: spin and spray water to clean dishes
• Pump and motor: circulates wash water and pushes water out to drain
• Heater/heating element: heats water and helps with drying
• Detergent dispenser and rinse-aid dispenser: releases detergent and rinse aid at the right time
• Door seal and vent: helps prevent leaks and manages moisture during drying

Here are a few real part names you may see for this model:

Knowing the correct part names helps you match symptoms to the right system. For example, leaks often point to the door seal or vent area, while poor cleaning often points to spray arms, pump circulation, or water fill problems.

• Match the symptom to the system (fill, wash, heat, drain, dry)
• Compare your old part’s shape and connector style
• Check for wear: cracks, swelling, mineral buildup, or broken clips
• If the dishwasher will not run at all, start with power and controls before replacing parts

On your Whirlpool dishwasher model DP920PFGQ3, the most reliable identifier is the model and serial tag, not a part number printed on the dishwasher. We use that model number to match the correct replacement parts for your exact build.

Check these common locations for the model and serial tag:

• Along the inside edge of the door (top or side of the inner door frame)
• On the tub rim around the door opening
• On the side of the door itself (visible when the door is open)
• Occasionally behind the lower toe kick panel area

Write down the full model number (DP920PFGQ3) and the serial number exactly as shown.

Dishwashers typically do not list individual part numbers on the appliance label. Instead:

• The model number identifies the dishwasher version
• The serial number identifies the production run
• The part number/part ID is used only when ordering a specific component

Once you have the model number, you can pick the exact part you need. For example, leaks at the door often point to the dishwasher door seal WPW10509257.

Other common part lookups for this model include:

• No heat or overheating symptoms: dishwasher thermostat WP661566
• Not filling properly: dishwasher water inlet valve WP8274220
• Not draining or fill/drain issues: fil&drnhos WPW10273574

Whirlpool dishwashers can use different components across similar-looking units. Using DP920PFGQ3 prevents ordering the wrong door seal, inlet valve, or pump-related part and saves time on returns.
