Whirlpool DU1100XTPQA dishwasher Parts

On a Whirlpool dishwasher model DU1100XTPQA, the quickest way to clear most error indicators and “reset” the control is to press CANCEL/DRAIN; the dishwasher runs up to a 2-minute drain (if needed) and clears the lights. Then select a cycle and press START/RESUME with the door fully latched (see the DU1100XTPQA owner's manual).

Reset steps (what to do first)

• Press CANCEL/DRAIN once.
• Wait for the drain to finish (up to about 2 minutes).
• If you still see water in the bottom, press CANCEL/DRAIN again to restart draining.
• Close the door firmly until it latches.
• Select your wash cycle and options, then press START/RESUME.

If the code comes back right away

A repeating error plus water left in the bottom usually points to a drain or heater-related issue, not just a one-time glitch.

Quick checks that fix many repeat errors

• Make sure the door is fully closed; if the door is opened mid-cycle, START/RESUME can flash and the cycle will not resume until you latch the door and press START/RESUME.
• Run CANCEL/DRAIN before starting a new cycle (the manual recommends draining before restarting).
• Confirm the dishwasher has power (breaker not tripped).
• If the Clean light is flashing, the manual indicates a malfunction that often involves the heater circuit.

What the symptoms usually mean

Symptom you see	Most common cause	What to try next
Water stays in bottom after stopping	Drain restriction or weak drain pump	Check drain path; consider dishwasher drain pump WPW10348269 if draining is weak
Clean light flashing	Heater circuit problem	Inspect wiring and heating circuit; consider dishwasher heating element W10518394
Starts then stops, then repeats	Door latch interruption or control sensing a fault	Latch door, reset with CANCEL/DRAIN, then restart

Why it matters

Clearing the indicators with CANCEL/DRAIN resets the cycle logic so you can restart cleanly. If the same error returns after a proper reset and drain, troubleshooting the drain system, heater circuit, or control components prevents repeat stoppages and standing water.

Whirlpool Corporation manufactures dishwashers sold under several major brands, including Whirlpool, Maytag, KitchenAid, JennAir, and Amana. For your Whirlpool DU1100XTPQA dishwasher, our DU1100XTPQA owner's manual is the best place to confirm features and service information for this specific model.

Whirlpool dishwasher brands you will commonly see

These are the most common dishwasher brand names produced within the Whirlpool family:

• Whirlpool
• Maytag
• KitchenAid

How this helps when you are shopping parts or service

Brand families matter because parts, controls, and wash systems can be shared across multiple model lines, but the exact fit still depends on the model number.

• Always match parts to the full model number (DU1100XTPQA)
• Use the model to confirm electrical and mounting details before ordering
• Compare the symptom to the correct troubleshooting section for your platform
• If you see a fault or blinking pattern, check the right error-code family first

Quick comparison: what typically differs by brand line

Brand line	Typical positioning	What often changes	What often stays similar
Amana	Value	Fewer cycles, simpler options	Core wash and drain design concepts
Whirlpool	Mainstream	Cycle options, noise features	Many service procedures and parts families
Maytag	Heavy-duty	Motor and filtration variations	Similar installation basics
KitchenAid	Premium	Racks, drying features, controls	Shared component architecture in some series
JennAir	Luxury	Styling, advanced features	Fundamental dishwasher plumbing/electrical needs

Why it matters

When you are diagnosing issues like not draining, not drying, or no heat, the brand name alone is not enough. The model number (DU1100XTPQA) is what ensures you get the correct parts and the correct repair steps.

If you are troubleshooting a display or blinking-code issue, use our Whirlpool dishwasher error codes reference to narrow the problem to the right system (drain, heating, fill, or control).

On a Whirlpool dishwasher like model DU1100XTPQA, an F13 code points to a water-heating or water-temperature sensing problem during the cycle. In practice, we treat it as a “water not heating as expected” condition and troubleshoot the heater circuit, wiring, and control.

What to check first (fast, no parts)

• Reset the cycle and try again using the steps in the DU1100XTPQA owner's manual.
• Make sure the hot water supply is on and the sink water runs hot before starting.
• Confirm the door is fully latched; a paused or interrupted cycle can create confusing symptoms.
• Run a normal cycle and listen for filling, washing, then a drain; note where it stops.
• If the unit is not drying and the Sanitized light flashes at the end, that supports a heating issue.

Parts that commonly relate to an F13-style heating fault

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

• Heating circuit: dishwasher heating element W10518394
• Temperature/soil sensing: sensor WPW10705575
• Main control (commands heat): dishwasher electronic control WPW10084141

Symptom you notice	Most likely area	What we do next
Dishes cold, no drying	Heater circuit	Check heater and wiring, then control
Sanitized light flashes	Water not reaching temp	Verify heater operation and incoming hot water
Intermittent, random stops	Control or door/power interruption	Reset, check power, then control diagnostics

Why it matters

Heating is what boosts wash performance and activates drying. When the dishwasher cannot raise water temperature, cycles can run poorly, leave residue, and trigger sanitation-related indicators.

On a Whirlpool dishwasher, the F9 E1 error means the dishwasher is having a drain problem (it is not pumping water out fast enough or it senses water is still in the tub). On model DU1100XTPQA, start by checking simple drain and power items in the DU1100XTPQA owner's manual.

What to check first (fast, no parts)

• Cancel the cycle and let the unit try to drain; then check for standing water in the bottom.
• Make sure the door is fully closed and latched.
• Check the kitchen sink drain for a slow clog (a backed-up sink can block dishwasher draining).
• Inspect the drain hose routing for kinks, crushing, or a low loop that is missing.
• If the dishwasher is dead or acts erratic, check the house breaker or fuse.

Common causes and the parts that usually fix them

Drain errors are usually caused by a restriction in the drain path or a weak pump.

Symptom you see	Most likely cause	What to do next
Water left in tub after drain	Clog in hose, disposer inlet, or drain path	Clear blockage; verify hose routing
Hums but won’t drain	Drain pump jammed or failing	Inspect/replace dishwasher drain pump WPW10348269
Drains slowly or intermittently	Partially blocked hose or weak pump	Check hose; consider pump replacement
Fills but then throws drain error	Control not sensing proper drain, or pump issue	Check pump and wiring; then control diagnostics

Why it matters

When the dishwasher cannot drain, dirty water can be recirculated, cycles can stop mid-wash, and the unit may protect itself by ending the cycle and displaying F9 E1. Fixing the drain path restores normal wash performance and helps prevent odors.

If you need a reset after fixing the cause

After clearing the drain issue, a reset can help clear the code and restart normal operation. Use the steps in how to reset a Whirlpool dishwasher.

On a Whirlpool DU1100XTPQA dishwasher, error code 11 (often shown as “FA” or 11 flashes on some Whirlpool platforms) points to a problem with the optical water indicator (turbidity) sensor that monitors how clean the wash water is; the dishwasher may extend or repeat rinsing when it reads the water as dirty.

What to check first (quick fixes)

• Cancel the cycle and run a reset sequence from the DU1100XTPQA owner’s manual.
• Turn off power at the breaker for 1 minute, then restore power and try a normal cycle.
• Clean the filter area and sump; heavy soil can keep water cloudy and trigger the sensor.
• Verify the water is hot enough at the sink before starting (run hot water 30 to 60 seconds).
• Use fresh detergent and the correct amount; too much detergent can cause filming and false “dirty water” readings.

When it is likely a sensor issue

If the dishwasher keeps repeating rinses, cleans poorly, or shows the code again after cleaning and resetting, the turbidity sensor circuit is the next place to focus.

Common causes include:

• Sensor lens coated with grease or mineral buildup
• Loose or corroded wiring connection at the sensor
• Failed sensor
• Control not interpreting the sensor signal correctly

Parts that may be involved

Symptom you notice	Most likely area	Example part for this model
Code returns quickly after reset	Turbidity sensor or wiring	Sensor WPW10705575
Random behavior, cycle logic seems “off”	Control board	Dishwasher electronic control WPW10084141

Why it matters

The turbidity sensor helps the dishwasher decide whether to advance the cycle or add extra rinsing. When it misreads water clarity, you can get longer cycles, higher water use, and inconsistent cleaning.
