Hotpoint HDA3740G02SA dishwasher Parts

On your Hotpoint dishwasher model HDA3740G02SA, the model number is printed on a label on the tub wall just inside the door. Open the door fully and look along the inner side wall of the tub near the front opening.

Quick steps to locate the model tag

• Open the dishwasher door and keep it fully open.
• Look at the tub wall (the metal or plastic side wall inside the dishwasher).
• Check just inside the door opening, near the front edge of the tub.
• Wipe the area with a damp cloth if the label is hard to read.
• Write down both the model number and serial number for parts lookup and service records.

Common label locations (what to check first)

Most Hotpoint dishwashers in this series place the tag in one of these spots:

Location inside the dishwasher	What you will see	Why it helps
Tub wall just inside the door	Model and serial label	Best for ordering the correct parts
Near the front edge of the tub opening	Sticker or stamped plate	Easy to read with the door open

Why it matters

We use the exact model number to match the correct diagrams and replacement parts for your dishwasher. Even small model variations can change which items fit (for example, a door seal, drain hose, or pump and motor assembly).

For diagrams and model identification details, use the owner's manual.

For a Hotpoint dishwasher model HDA3740G02SA, the most commonly replaced parts are the ones that handle water movement, sealing, heating, and loading. When these wear out or clog, you typically see leaks, poor cleaning, no-drain symptoms, or the dishwasher not running as expected (see the owner's manual).

Commonly replaced dishwasher parts (and what they affect)

• Door seals and inserts: stop leaks around the door opening
• Drain components: help the unit empty water at the end of a cycle
• Wash pump and motor: drives spray pressure for cleaning
• Heating components: help with water temperature and drying performance
• Racks and rollers: keep dishes positioned correctly and racks gliding smoothly
• Control panel parts: affect cycle selection and starting
• Detergent and rinse-aid dispenser parts: affect soap release and drying/spotting

Parts on this model that are often replaced

These are common wear items we see customers replace on HDA3740G02SA:

Symptom	Likely part type	Example part for this model
Water leaking at the door	Door seal	Dishwasher door seal WD08X10057
Not draining or drains poorly	Drain hose or drain solenoid	Dishwasher drain hose WD24X10014, dishwasher drain solenoid kit WD21X10060
Poor cleaning, weak spray	Pump and motor	Mechanism WD26X10013
Not drying well	Heating element	Elem htg asm WD05X26780
Rack won’t roll smoothly	Rack rollers	Rack roller WD12X271

Quick checks before you replace anything

These steps solve a lot of “bad part” complaints without parts:

• Disconnect power before any inspection (turning the dishwasher off does not disconnect power).
• Check for loading issues that block spray or the detergent cup.
• Clean the control panel with a lightly damp cloth, then dry thoroughly.
• If it is not draining well, check the air gap (if your setup uses one).
• Avoid letting lightweight plastic items fall to the bottom where they can contact the heating element.

Why it matters

Replacing the correct part restores normal wash pressure, proper draining, and leak protection. It also prevents secondary damage, like water leaks at the door seal or overheating issues caused by items contacting the heater.

A Hotpoint HDA3740G02SA dishwasher that leaks from underneath is usually leaking at the door area (misalignment or worn seals) or from a hose or pump connection under the tub. Start by checking door-to-cabinet interference and then inspect the drain hose and door seals for damage.

Quick checks that fix many “underneath” leaks

• Make sure the dishwasher is level left-to-right and front-to-back; poor leveling can affect door sealing and rack operation.
• Confirm the dishwasher is centered in the cabinet opening; the door should not rub adjacent cabinets.
• Open and close the door and verify the door spring does not contact the fill hose, water line, wiring, or components.
• Run a short cycle and look for the first drip point with a flashlight (door edge vs. center underside).
• If the leak appears at the bottom front, focus on door sealing and door alignment first.

For the model-specific positioning and leak-check steps, follow the installation guide.

Most common leak sources on this model

Where you see water	Likely cause	What to do next
Bottom front, near corners	Door not sealing, door rubbing cabinets	Re-center unit, re-level, check seal condition
Under tub, toward sink side	Drain hose issue	Inspect/replace dishwasher drain hose WD24X10014
Under tub, more central	Pump or seal leak	Inspect pump area; consider mechanism WD26X10013 if leaking at motor/pump

Parts that commonly solve leaks

• If the door gasket is split, hardened, or flattened, replace the dishwasher door seal WD08X10057.
• If the inner seal insert is damaged or missing, replace the dishwasher door seal insert WD08X10015.
• If you find moisture or drips at the hose connection or the hose is brittle or kinked, replace the dishwasher drain hose WD24X10014.

Why it matters

Leaks from underneath can damage flooring and cabinets quickly. Correcting alignment (so the door does not hit cabinetry) and replacing worn seals or a compromised hose stops repeat leaks and helps the dishwasher wash and drain normally.

Yes, for your Hotpoint HDA3740G02SA dishwasher we recommend DIY replacement only for straightforward, low-risk parts (racks, rollers, some dispenser pieces, and door seals). For electrical, wiring, or leak-related repairs, shut off power and water first and follow the steps in the owner's manual and installation guide.

Good DIY repairs vs. repairs to leave to a technician

Many dishwasher fixes are mechanical and accessible; others involve electrical shock risk, water leaks, or wiring in the junction box.

• Usually DIY-friendly: replacing a rack, rack rollers, silverware basket, detergent cup cover, and some door sealing parts
• Use extra caution: drain hose swaps and anything involving clamps or water connections
• Best left to a technician: wiring/junction box work, diagnosing no-start issues, and pump/motor or heating circuit troubleshooting

Safety steps we follow before any repair

The manual for this dishwasher is clear that turning the dishwasher off does not disconnect it from power; disconnect power at the breaker before maintenance.

• Turn off power at the breaker (not just the control panel)
• Turn off the water supply before disconnecting hoses
• Pull the lower rack out partway to confirm it rolls smoothly and does not drift
• Keep wiring secured and not pinched or rubbing door springs
• After reassembly, restore water and check carefully for leaks

Common parts customers replace on HDA3740G02SA

If your issue matches one of these, DIY is typically practical with basic tools.

Symptom	Common DIY part to check/replace	Example part on this model
Door leaks	Door seal or seal insert	Dishwasher door seal WD08X10057
Rack won’t roll smoothly	Rack roller	Rack roller WD12X271
Not draining well (after clearing blockage)	Drain hose or drain solenoid kit	Dishwasher drain hose WD24X10014
Detergent door won’t stay closed	Detergent cup cover	Detergent cup cover WD16X297

Why it matters

Choosing the right DIY repair protects your kitchen from leaks and protects you from electrical shock. It also helps ensure the dishwasher is leveled, wired safely, and operating as designed after the repair.
