🔨 Pro Tip from Drew

For the WDT970SAKZ, you’ll almost always need the upper rack adjuster kit (part number W10712394). Here’s a common pitfall — don’t just replace the broken side. The other adjuster is likely worn too, and if you skip it, you’ll find yourself back in the same spot in a few months. Also, make sure to extend the rack fully before snapping the new adjuster into the track rail; otherwise, it won’t seat correctly.

Common Symptoms & Causes

If your Whirlpool WDT970SAKZ dishwasher has a broken rack adjuster, you might notice one or more of the following symptoms during loading or operation:

  • The upper dish rack drops unevenly or collapses on one side when loaded.
  • The rack adjuster button snaps or feels loose and no longer locks into position.
  • The upper rack slides out unexpectedly during the wash cycle.
  • One side of the rack sits noticeably lower than the other, causing dishes to shift.

These issues typically arise from normal wear and stress fractures in the plastic adjuster housing, which weaken over time and eventually lead to broken locking tabs or release buttons.

Safety First

  • Unplug the dishwasher from the power outlet before starting any repair — never work on a live appliance.
  • Shut off the water supply valve before disconnecting any water lines or hoses.
  • Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
  • Take photos with your phone before disconnecting any wiring harnesses or connectors.
  • Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

Start by opening the dishwasher and pulling the upper rack all the way out for clear access. Locate the height adjuster levers—these are usually orange or gray plastic tabs mounted on the outside of each rack rail. Check for visible cracks, broken tabs, or any lever that feels loose and fails to snap into position; these signs confirm the adjuster is the culprit.

Step 2

If you find an adjuster lever that’s cracked or doesn’t click firmly into place, it needs to be replaced. A damaged lever won’t hold the rack level, leading to poor wash coverage and rattling during cycles. To replace it, flex the old lever outward to unclip it from the rail mounting points, then press the new adjuster unit firmly onto those same points until it snaps into place. Pro tip: order adjuster assemblies in pairs to ensure both sides match and prevent uneven rack lean.

Step 3

With the rack pulled out, inspect each wheel along the bottom for cracks, flat spots, or missing chunks. Damaged wheels can cause the rack to bind or tip instead of rolling smoothly in the tub rails. Replace any cracked wheels by pressing the old one off its axle pin and snapping the new wheel on—no tools required. I recommend using genuine OEM wheels, as aftermarket versions might vary slightly in diameter, causing the same binding issues.

Step 4

Before reinstalling the rack, wipe out both rack rail channels on the tub side walls with a soft damp cloth. Grease, mineral deposits, and food debris can accumulate in these channels, creating resistance that mimics the symptoms of bad wheels or a broken adjuster, so cleaning first ensures you’re not overlooking a simple fix. Avoid abrasive pads that could scratch the channel surface and create rough spots for future buildup.

Step 5

Slide the upper rack back into the rail channels and test all three height positions by pressing the adjuster levers and moving the rack up or down. Each position should drop in and click firmly without any wobble or tilt, confirming that the adjusters and wheels are seated correctly. If any position feels soft or fails to hold, re-examine the adjuster on that side—a new part that doesn’t click fully may not be seated properly.

Step 6

Once the rack operates correctly, set its height to match your current load. Raise the upper rack to its highest position to clear the lower rack for tall pots or casserole dishes, and lower it when washing tall glasses or stemware to prevent contact with the spray arm or tub ceiling. Taking a moment to adjust before each wash cycle protects your dishes and ensures the spray arms can rotate freely for a thorough clean.

When to Call a Professional

If the problem persists after you’ve followed all the steps, it may be a sign of a failed main control board, a seized circulation or drain pump, or wiring that needs specialized diagnostic equipment. In that case, it’s best to contact a licensed appliance technician — and don’t forget to shut off the water supply valve before any work that opens the fill or drain circuit.

How Much Does This Repair Cost?

Replacing a broken rack adjuster on the Whirlpool WDT970SAKZ typically costs $15–$45 in parts if you do it yourself. If you opt for a professional service call for the same repair, expect to pay $150–$300 once you factor in labor and fees. Choosing the DIY route can save you over $100, making this an affordable fix.

The Rack Wheels That Actually Stop the Upper Rack from Dragging on the WDT970SAKZ

When the adjuster clips crack or the wheels wear flat, the upper rack stops gliding smoothly and starts binding or dragging—this is the real culprit behind most “rack won’t move” complaints on this model. Swapping out all four to eight wheels is usually the fastest path to a working rack again, and it’s cheaper than replacing the entire adjuster assembly.

What works

  • Wheels come pre-matched as a set, so you’re not hunting for individual sizes or struggling with mismatched pairs that cause the rack to tilt.
  • Installing them is genuinely simple—pop off the old wheel, slide the new one onto the axle pin, and you’re done in seconds per corner; no special tools needed.
  • The difference is immediately noticeable; a rack that was stuttering or stuck suddenly glides smoothly again, even under a full load of dishes.

What doesn’t

  • If the adjuster clips themselves are actually cracked or bent, new wheels alone won’t fix the problem—you’ll still have a binding rack and will need to replace the full adjuster kit instead.
  • Wheels vary slightly between aftermarket suppliers in material hardness; some softer compounds wear faster, so compatibility can be hit-or-miss if you don’t order the right set for your specific adjuster design.

I’ve had homeowners call back because they ordered wheels alone when the real issue was a cracked clip—take a close look at the adjuster assembly before ordering, because a visual inspection of the plastic clips themselves will save you a return trip. If everything looks intact, rack wheels (set of 4–8) will get the job done.
