Whirlpool DU1345XTVB1 undercounter dishwasher Parts

On the Whirlpool DU1345XTVB1 dishwasher, replacing the control panel typically costs $315 to $350 for the part, plus labor if you hire service. If you DIY, your total is usually the part cost plus basic supplies; a service call often adds the biggest extra cost.

What you’ll usually pay (parts vs. labor)

Control panel replacement cost depends on whether you’re paying for labor and whether any related parts (like a console overlay or control board) are also needed.

• DIY parts-only: typically the control panel price
• Professional repair: part price plus service call and labor time
• If symptoms point elsewhere: you may need a different part (for example, the electronic control board)
• If the dishwasher is dead: check power and the house fuse or breaker first (per the troubleshooting guidance in the manual)

Scenario	What you pay for	Typical cost drivers
DIY replacement	Control panel only	Correct diagnosis, basic tools
Pro replacement	Control panel + labor	Service call, hourly labor
Misdiagnosed issue	Extra parts + extra labor	Control board, wiring, door switch checks

The correct part for this model

For DU1345XTVB1, the control panel listed for this model is:

• Control panel WPW10142945

If the buttons respond inconsistently, lights act erratic, or cycles start and stop unexpectedly, the issue can also be in the main control.

• Optional related part to compare: dishwasher electronic control board WPW10084142

Before you buy: quick checks that prevent wasted cost

These checks help confirm it’s really a control panel problem and not a power or latch issue.

• Verify the door closes tightly and latches
• Confirm the dishwasher has power at the outlet/junction box
• Check the household fuse or circuit breaker
• Look for loose or damaged wiring at the door (hinge area is common)
• Review the troubleshooting steps in the DU1345XTVB1 owner’s manual

Why it matters

A control panel is one of the higher-cost dishwasher parts. Spending a few minutes confirming power, door latch operation, and control symptoms helps you avoid buying the wrong part and paying twice.

Yes, for Whirlpool DU1345XTVB1 you can replace many dishwasher parts yourself if you can safely shut off power and water, follow the step-by-step procedure, and use basic hand tools. We recommend using the DU1345XTVB1 owner's manual for operating and safety guidance and the DU1345XTVB1 installation guide for electrical and mounting details.

Parts that are usually DIY-friendly

These repairs are typically straightforward because they involve accessible components and minimal wiring.

• Replace a leaking door seal such as the dishwasher door seal W10542314
• Swap a worn drain hose (routing and clamps matter) such as the dishwasher drain hose 8269144A
• Replace a no-heat symptom part like the dishwasher heating element W10518394 (after confirming power is off)
• Replace a failed drain pump such as the dishwasher drain pump WPW10348269 when the unit will not drain
• Clean and inspect the tub area and check the drain air gap if draining is slow (a common maintenance step)

When we recommend a technician

Some repairs are still doable for experienced DIYers, but they carry higher risk of leaks, electrical shock, or repeat failures if diagnosis is off.

• Electrical troubleshooting at the terminal box or control wiring
• Control and power issues (intermittent dead unit, burning smell, repeated breaker trips)
• Motor and sump-area repairs that require deeper disassembly

Quick safety checklist before you start

The installation instructions call out key electrical and mounting safety points.

• Disconnect power at the breaker or unplug; use a grounded 3-prong outlet (no adapter, no extension cord)
• Shut off the water supply valve before disconnecting any hose
• Keep the power cord from touching the motor or lower tub area
• Confirm the dishwasher is level front-to-back and side-to-side after reassembly
• Secure the dishwasher to prevent shifting when the door opens

DIY difficulty guide (typical)

Repair type	Typical difficulty	Common tools
Door seal replacement	Easy	Phillips screwdriver, towel
Drain hose replacement	Easy to moderate	Pliers, clamp tool
Heating element replacement	Moderate	Nut driver, multimeter
Drain pump replacement	Moderate	Nut driver, pliers
Electrical diagnosis	Advanced	Multimeter, wiring diagram

Why it matters

Dishwashers combine water, heat, and electricity. Following the correct shutdown steps and re-checking level and mounting helps prevent leaks, poor washing, and electrical hazards after the repair.

On a Whirlpool dishwasher, an F13 code points to a water-heating problem (the dishwasher is not sensing the expected temperature rise). On model DU1345XTVB1, this typically leads us to check the heating circuit, wiring, and the heater-related components listed in the DU1345XTVB1 owner's manual.

What to check first (safe, quick checks)

• Reset power: turn the dishwasher breaker off for 1 minute, then back on.
• Confirm the door closes and latches firmly; some cycles pause or stop if the door is not fully latched.
• Run hot water at the sink until it is hot, then start the cycle (improves initial fill temperature).
• Verify the home circuit is OK; a tripped breaker or blown house fuse can interrupt heating.
• If the unit stops mid-cycle or the Clean light flashes, follow the troubleshooting guidance in the manual.

Likely causes and the parts that match them

If the dishwasher fills and washes but does not heat or dries poorly, these are the most common suspects:

Symptom you notice	Most likely area	Part to consider for DU1345XTVB1
Water stays cool, poor drying	Heating circuit	Dishwasher heating element W10518394
Intermittent power, dead unit	Power protection	Fuse W10258275
Wash results vary, odd cycle behavior	Soil sensing	Dishwasher turbidity sensor WPW10705575

Why it matters

Heating affects wash performance and drying. When the dishwasher cannot heat correctly, it may extend the cycle, leave dishes wet, or trigger an error to prevent damage to the appliance and protect cleaning results.

Before replacing parts

• Disconnect power at the breaker before accessing internal components.
• Use a meter to check continuity and wiring condition; see how to use a multimeter to test electrical parts video.
• If you find damaged wires or loose connections, repair them correctly before installing new parts.

In a Whirlpool DU1345XTVB1 undercounter dishwasher, the most commonly replaced parts are the drain and wash components, water-fill parts, and door sealing parts. These items wear from heat, detergent, hard-water buildup, and normal use, and they directly affect cleaning, draining, and leak prevention.

Most common parts (and what they fix)

• Heating and drying issues: dishwasher heating element W10518394
• Won’t drain, standing water, or humming during drain: dishwasher drain pump WPW10348269
• Leaks at the door or water on the floor: dishwasher door seal W10542314
• Slow drain, siphoning, or drain leaks: dishwasher drain hose 8269144A (or dishwasher drain hose WPW10545278 depending on routing)
• No fill or weak fill: dishwasher water inlet valve W10648041
• Dead dishwasher or intermittent power: fuse W10258275

Quick troubleshooting before you buy a part

These checks often point to the right part group:

• Run hot water at the nearest sink until it is hot, then start the cycle (helps fill and wash performance).
• If it is not draining well, check and clean the drain air gap (if your setup uses one).
• If it will not fill, make sure the overfill protection float moves freely.
• If it will not start, check the house fuse or reset the circuit breaker.
• If cycles seem long, remember some cycles can run up to about 3.5 hours depending on soil level and water temperature.

Common symptoms to part mapping

Symptom	Most likely part area	Example part for DU1345XTVB1
Dishes not dry, water not heating	Heating circuit	Heating element W10518394
Water left in tub	Drain system	Drain pump WPW10348269, drain hose 8269144A/WPW10545278
Water leaking at bottom of door	Door sealing	Door seal W10542314
No water entering	Fill system	Water inlet valve W10648041
No power	Electrical protection	Fuse W10258275

Why it matters

Replacing the correct “high-wear” part restores cleaning and prevents secondary damage (like leaks reaching wiring or a weak fill causing long cycles). For model-specific access steps and safety notes, follow the DU1345XTVB1 installation guide and the DU1345XTVB1 owner’s manual.
