Whirlpool Dishwasher Heating Element Parts — Models & Compatibility

Your Whirlpool dishwasher isn't drying dishes anymore, or the cycle runs forever but dishes come out cold and wet. That's usually your heating element failing. This hub covers the W11537778 heating element assembly that fits over 100 Whirlpool, KitchenAid, Maytag, and Jenn-Air dishwasher models — including the WDT750SAK, WDTA50SAK, and KDFE104K series.

Is This the Right Part for Your Model?

Check your dishwasher's model number before ordering. You'll find it on a sticker inside the door frame — open the door and look along the top edge or the side. The model number starts with letters followed by numbers, like WDT750SAKW3 or KDFE104KBL0. Cross-reference it with the compatibility list below. This element replaces older part numbers W11412298, W11536143, W11047695, and AP7014587.

About This Replacement Part

The heating element assembly is what generates heat during the drying cycle and helps maintain water temperature during the wash. When it burns out — which happens after years of thermal cycling — your dishwasher completes its cycles but leaves everything soaking wet. You might also notice the heated dry option doesn't work, or the control board throws an error code because it's not sensing proper temperature. The W11537778 is a direct OEM replacement that includes the element housing and mounting hardware. It's the same part Whirlpool service techs install, just without the dealer markup.

Compatible Model Series

This heating element fits multiple Whirlpool families and their branded equivalents. The WDT750SAK series represents Whirlpool's mid-range dishwashers from recent years. The WDTA50SAK and WDTA80SAK lines are similar platforms with slightly different control panels. KitchenAid's KDFE104K models use the same chassis and heating system. If you've got a Kenmore with a 665.14xxx model number, that's a rebadged Whirlpool — check the full model string to confirm compatibility.

Installation Overview

Replacing a dishwasher heating element isn't complicated, but you need to disconnect power at the breaker first. The element sits at the bottom of the tub. You'll remove the lower spray arm, unscrew the mounting nut from underneath (accessed through the kick panel), disconnect the wire terminals, and pull the old element out. The new one installs in reverse. Takes about 30-45 minutes if you're methodical. The element comes with a rubber gasket that seals against the tub — make sure it seats properly or you'll get a leak.

Why Heating Elements Fail

Heating elements fail from repeated heat cycling and mineral buildup. Hard water deposits accumulate on the element surface over time, creating hot spots that eventually cause the element wire to burn through. Using too much detergent can also leave residue that accelerates corrosion. Most heating elements last 5-8 years depending on water hardness and usage frequency. Once the element opens (breaks the circuit), it can't be repaired — replacement is the only fix.

Verify Your Model Before Ordering

This part number covers a broad range, but dishwasher manufacturers change internal components without warning. Always verify your model number matches the compatibility list. If you've got an older dishwasher (pre-2015), double-check that your specific model revision is listed. The revision number is the last digit or two in your model string — like the '3' in WDT750SAKW3 or the '0' in KDFE104KBL0. Those matter.
