Whirlpool WDT730HAMZ Top-Control Dishwasher Repair

Most common issues on this model

Hidden top control panel and cycle start
Third rack, its rails and spray coverage
Boost cycle heating and fill
Drain pump and filter area
Door latch and switch

The WDT730HAMZ is a Whirlpool dishwasher, 24 inches wide, with its controls hidden along the top of the door. It has a stainless tub, a third rack and boost cycle options, and a fingerprint resistant stainless exterior. You will usually see it in a remodeled Houston kitchen, tucked under the counter beside the sink.

With hidden controls, a no-response complaint takes us to the control panel on the top edge of the door and the door latch and switch. The third rack is another thing we examine: its rails can bind and a loaded rack can block a spray arm, which leaves dishes unclean. Boost cycles also ask more of the fill valve and the heating path.

Revisions of this number exist, so the label gets read in full before any part is ordered. The price is written down before we begin, and our repair carries a 30-day workmanship warranty.

WDT730HAMZWDT730HAMZ questions

My WDT730HAMZ controls do not respond. What is checked?

We test the top control panel, the door latch and switch and the power supply to the machine. Because the controls are hidden on the top edge, we also look for moisture or a worn connection there.

Can the third rack cause dishes to stay dirty?

Yes, if its rails bind or a tall item blocks a spray arm. We check the rack movement and arm clearance, then run a test cycle to see the spray pattern.

What does the boost option change for service?

A boost cycle is a harder wash, so it puts more demand on the heating and water fill. We test both when it does not seem to finish the job.
