Whirlpool DU1055XTSS2 dishwasher Parts

For the Whirlpool DU1055XTSS2 dishwasher, the installation guide lists a 24-1/2 inch overall width and a minimum height of 33-7/8 inches (86 cm), which can apply when the wheels are removed. For exact fit in your cabinet opening, use the product and cutout diagrams in the installation guide.

Model DU1055XTSS2 size details (from the installation guide)

These are the key measurements shown in the product dimensions and cutout dimensions diagrams:

• Overall width: 24-1/2 in (62.2 cm)
• Minimum height: 33-7/8 in (86 cm) minimum
• Toe-kick/front clearance shown: 21 in (53.3 cm)
• Cutout opening width: 24 in (61 cm) minimum
• Cutout opening height: 34 in (86.4 cm) minimum (measured from the lowest point under the countertop)

How to measure so the dishwasher fits correctly

We recommend measuring both the dishwasher opening and the path the unit must slide through.

• Measure opening width at the front and back (cabinet sides can taper)
• Measure opening height at the lowest point under the countertop
• Check for floor height changes (tile that stops partway in can change leveling)
• Confirm side clearance so insulation and hoses do not bind
• Plan routing for the drain hose, water line, and wiring in the shaded cutout areas

Quick reference table

Measurement	What it affects	Typical check
24-1/2 in overall width	Whether the unit physically fits	Compare to opening width
33-7/8 in minimum height	Whether it clears the countertop	Compare to lowest underside point
24 in minimum cutout width	Cabinet opening requirement	Measure narrowest point
34 in minimum cutout height	Cabinet opening requirement	Measure at lowest point

Why it matters

Dishwasher fit issues usually come from the cabinet opening, flooring, or countertop height, not the dishwasher itself. Using the DU1055XTSS2 cutout dimensions helps prevent binding, leaks from mis-leveling, and door alignment problems.

Drain and wash performance problems are the most common issues we see with Whirlpool dishwashers like model DU1055XTSS2. They usually show up as standing water, a cycle that seems to run too long, or dishes that come out dirty because water is not moving or heating correctly.

What “most common” looks like in real symptoms

• Water remains in the tub at the end of the cycle
• Dishes are gritty or have food soil left behind
• The dishwasher pauses often or seems to run a long time while heating
• The START/RESUME light flashes and the unit will not continue until the door is opened and closed
• Poor drying, especially plastics

Quick checks we recommend first (no parts yet)

1. Confirm the cycle finished; water can remain if the cycle was interrupted.
2. Open and close the door, then press START/RESUME if the indicator flashes (the control can pause if it thinks the door is not latched).
3. Check power at the breaker or fuse if the dishwasher is dead.
4. Make sure the water shutoff valve is on.
5. If the dishwasher will not fill, press the overfill float down to be sure it moves freely.

For model-specific operating steps and cycle behavior, use the DU1055XTSS2 owner's manual.

Parts that commonly solve the underlying cause

When the basic checks do not fix it, these are the most common “root-cause” parts for draining, washing, and heating issues:

Problem you notice	Common cause	Part to consider for DU1055XTSS2
Standing water, won’t drain	Drain pump not pumping, blockage after pump	Dishwasher drain pump WPW10348269
Poor drying, long heat-up, “clean” light flashing related to heater circuit	Heater circuit problem, failed heater	Dishwasher heating element W10518394
Won’t fill or fills slowly	Water inlet valve not opening fully	Dishwasher water inlet valve WPW10158389

Why it matters

Drainage and heating problems do more than leave water behind; they also reduce wash pressure and water temperature. That combination leads to poor cleaning, longer cycles (while the dishwasher tries to heat), and more residue on dishes.

On a Whirlpool DU1055XTSS2 dishwasher, an F2 E2 error is typically cleared by resetting the control and then restarting the cycle. We recommend canceling the current cycle (so the control clears), restoring power if needed, and then pressing START/RESUME with the door fully latched (see the DU1055XTSS2 owner's manual).

Quick reset steps (most effective order)

• Press CANCEL/DRAIN once; let the dishwasher run the 2-minute drain if it starts.
• When the indicators clear, select your cycle again.
• Close the door firmly until it latches.
• Press START/RESUME.
• If the controls are locked, press and hold HEATED DRY for 4 seconds to unlock, then try START/RESUME again.
• If the error returns immediately, turn power off at the breaker for 5 minutes, restore power, then retry.

What to check if the code comes back

F2 E2 is commonly tied to a keypad or control input issue. Before replacing parts, we check these basics:

• Door latch: door must be fully closed; an unlatched door can prevent START/RESUME from working.
• Control lock: the lock light means buttons are disabled until unlocked.
• Stuck key: press each key once to confirm none feel jammed.
• Power interruption: after a power loss, you may need to open and close the door, then press START/RESUME.
• Moisture on the console: wipe the control area dry and retry.

Parts that are often involved (when troubleshooting points to the control)

If the keypad or control is failing, these are common repair paths for this model:

Symptom	Most likely area	Example part for DU1055XTSS2
Buttons do not respond, lock is off	Console/control input	Control panel (black)
Random beeping or cycles changing	Electronic control	Electronic control

For DU1055XTSS2, the matching control board is the dishwasher electronic control WPW10084141.

Why it matters

Clearing the cycle with CANCEL/DRAIN and restarting with the door latched restores normal operation after an interruption and helps confirm whether the issue is a one-time control glitch or an ongoing keypad/control problem.

Most Whirlpool dishwashers, including the Whirlpool DU1055XTSS2, typically last 10 to 12 years with normal household use. Regular cleaning, correct detergent use, and fixing small issues early (like draining or drying problems) help you reach the high end of that range.

Typical lifespan and what affects it

A dishwasher’s life is mostly determined by heat, water quality, and how hard the pump system works over time.

• Usage frequency: 1 load per day lasts longer than multiple loads daily
• Water hardness: hard water speeds up scale buildup on internal parts
• Maintenance habits: cleaning filters and wiping the door seal prevents leaks and odors
• Drying system wear: heavy use of heated dry stresses heating components
• Small failures left unresolved: slow drains and poor wash performance strain the motor and pump

What “end of life” usually looks like

These are the most common signs a Whirlpool dishwasher is nearing replacement time.

• Repeated no-heat or poor drying complaints
• Not draining or leaving standing water after cycles
• Loud grinding or humming during wash or drain
• Leaks at the door or from the tub area
• Cycles that stop mid-cycle or act erratically

If you’re seeing heating or drying issues, the dishwasher heating element W10518394 is one of the common wear parts to check for this model.

Quick maintenance that extends lifespan

Use these habits to keep the DU1055XTSS2 running longer.

• Run hot water at the sink before starting a cycle (helps fill temperature)
• Use rinse aid and keep the dispenser filled
• Clean the tub and spray arms regularly
• Inspect and wipe the door sealing surfaces
• Address slow draining quickly (kinks, clogs, or a weak pump)

For model-specific operating and care steps (loading, detergent, rinse aid, cycle use), follow the owner's manual.

Common “repair vs. replace” decision guide

Situation	What it usually means	Typical next step
One clear failure (won’t drain, won’t heat)	Single part issue	Repair is usually worthwhile
Multiple symptoms (leaks + no heat + noisy motor)	Several worn systems	Compare repair cost to replacement
Tub damage or repeated major failures	Structural or recurring issue	Replacement often makes more sense

Why it matters

Knowing the typical 10 to 12 year lifespan helps you plan: if your DU1055XTSS2 is near that age, investing in maintenance and targeted repairs can prevent surprise downtime and protect cabinets from leak damage.
