Common Symptoms & Causes

If your Whirlpool WDT970SAKZ dishwasher has a broken rack adjuster, you may notice one or more of the following signs 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

This issue is typically caused by normal wear and stress fractures in the plastic adjuster housing, which weaken over time and eventually cause the locking tabs or release buttons to break entirely.

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

Open the dishwasher and pull the upper rack all the way out so you have clear access to both sides. Locate the height adjuster levers — typically orange or gray plastic tabs mounted on the outside of each rack rail — because these are the components that lock the rack into its three height positions. Look for visible cracks, broken tabs, or a lever that feels loose and no longer snaps decisively, as any of these signs confirm the adjuster is the source of the problem.

Step 2

If an adjuster lever is cracked, warped, or fails to click firmly into position, it needs to be replaced — a damaged lever cannot reliably hold the rack level, which causes poor wash coverage and rattling during the cycle. To replace it, flex the old lever mechanism outward to unclip it from the rail mounting points, then press the new adjuster unit firmly onto those same points until it snaps fully into place. Pro tip: order adjuster assemblies in pairs so both sides match, preventing uneven rack lean.

Step 3

With the rack still pulled out, inspect every wheel along the bottom of the rack for cracks, flat spots, or missing chunks, because damaged wheels cause the rack to bind, wobble, or tip rather than 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 are required. Using genuine OEM wheels is worth the extra cost, as aftermarket versions sometimes have slightly different diameters that cause the same binding problem.

Step 4

Before reinstalling the rack, wipe out the full length of both rack rail channels on the tub side walls using a soft damp cloth. Grease, mineral deposits, and food debris accumulate in these channels and create resistance that can mimic the symptoms of bad wheels or a broken adjuster, so cleaning them first rules out a simple fix. Avoid abrasive pads, which can scratch the channel surface and create rough spots that accelerate future buildup.

Step 5

Slide the upper rack back into both rail channels and test each of the three height positions by pressing the adjuster levers and moving the rack up or down. At each position, the rack should drop in and click firmly with no side-to-side wobble or forward tilt, confirming the adjusters and wheels are seating correctly. If any position still feels soft or fails to hold, re-examine the adjuster on that side — a new part that does not click fully is likely not seated completely on the mounting points.

Step 6

Once the rack operates correctly, set the height to match your current load: raise the upper rack to its highest position when you need the extra clearance on the lower rack for tall pots or casserole dishes, and lower it when you are washing tall glasses or stemware on the upper rack to prevent them from hitting 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 issue persists after completing all steps above, the problem may involve the sealed refrigerant system, a failed main control board, or wiring that requires specialized diagnostic equipment. Contact a licensed appliance technician — attempting sealed-system repairs without EPA 608 certification is illegal and unsafe.
