How to Install Dishrack Roller WP99002947 in a Whirlpool Pressure Washer
If your Whirlpool pressure washer is pressure washer not working properly, a worn dishrack roller can slow the whole job down. You may hear scraping, feel rough movement, or see the rack bind. The fix is a straight part swap in many cases. This guide shows How to Install Dishrack Roller WP99002947 without guesswork.
You only need a few hand tools and a little patience. The job usually takes 30 to 60 minutes. It sits in the medium range for difficulty, so take your time and keep parts organized. The goal is smooth movement again, not a rushed close-up.
The OEM number matters here. WP99002947 is the part name and number you should match before you start. Your listed models are ADB1200AWS, ADB1200AWW, ADB1500AWB, ADB1500AWS, and ADB1500AWW. Keep that list close while you work.
What You Should Know Before You Start
A roller wears out when it gets cracked, flat, or stiff. Dirt and buildup can make it worse. Sometimes the rack only drags when loaded. Other times it sticks even when empty. Either way, the roller needs a close look.
You should shut the unit down before touching any moving part. Unplug power if your setup uses a cord. Turn off water supply if needed for your machine. Let hot parts cool before you reach inside.
Take a photo before removal. That photo helps with orientation later. Small parts can look harmless until you try to reinstall them upside down. A quick picture saves time.
You should also clear a clean work area. A towel on the floor helps catch loose clips or washers. A shallow tray works well for small hardware. Keep removed parts in order so you can compare them later.
If the old roller is only dirty, clean it first. If the wheel stays rough or wobbly, replace it. A good part should roll freely and sit tight on its mount. A bad one often feels loose, gritty, or cracked.
Tools You’ll Want
You do not need a full shop for this job. Keep the setup simple.
- Phillips screwdriver
- Flat blade screwdriver
- Needle-nose pliers
- Small container for hardware
- Clean cloth or towel
If your model uses a different fastener style, use the correct driver for that screw head. Do not force a tool into the fastener. Stripped screws turn a small job into a bigger one fast.
Identify the Roller First
Before removal, inspect the roller area closely. Look for cracks in the wheel. Check the axle, clip, or holder around it. See whether the mount is bent or loose. A damaged mount can cause the same symptoms as a worn wheel.
Roll the part by hand if you can reach it. It should move without grinding. If it binds, the problem may be the wheel itself. If the wheel spins but sits crooked, the support piece may also need attention.
Match the old part to WP99002947 before you install anything. Shape matters. Hole placement matters. Clip style matters. A part can look close and still be wrong.
How to Install Dishrack Roller WP99002947
This section walks you through the swap step by step. Move slowly and keep track of every part you remove.
1) Remove the rack from the machine
Pull the rack out until it stops. Lift it only as far as needed. If a stop clip or end tab blocks removal, release it gently. Do not twist the rack hard. That can bend the rails.
Set the rack on a flat surface. Give yourself room on both sides. You want enough space to see the roller mount clearly.
2) Find the worn roller
Look at the roller that needs replacement. Check both ends of the mount. Some rollers sit on a pin or axle. Others snap into a holder. Identify the exact way yours is held in place before you pry anything.
If you cannot see the lock point, rotate the rack slightly. Light from the side helps. A flashlight can reveal the clip edge or tab. Once you see the retainers, removal gets much easier.
3) Release the old roller
Use a flat blade screwdriver or needle-nose pliers if the clip must be lifted. Work gently. The goal is to release tension, not break the holder.
If a pin holds the wheel, pull it straight out when free. If the roller snaps in, press the tabs just enough to release the wheel. Keep one hand on the part so it does not spring away.
Place the removed wheel beside the new one. Compare them side by side. Check size, shape, and mounting points. If they differ, stop and recheck the part number.
4) Clean the mount area
Wipe the bracket, axle area, and nearby track. Remove grease, food film, or grit. Even a good roller will drag if the mount is dirty.
Inspect the holder again after cleaning. Cracks may show up once the dirt is gone. If the bracket is damaged, a new roller alone may not fix the movement problem.
5) Install the new roller
Line up WP99002947 with the mount. Keep the orientation the same as the old part. Slide or snap it into place with even pressure.
If it uses a clip, make sure the clip locks fully. If it uses a pin, seat the pin straight and snug. The wheel should sit square and move freely. It should not wobble or rub the side of the mount.
Turn the wheel by hand after install. It should roll without noise or resistance. If it feels tight, remove it and check alignment again. Small misalignment can create bigger drag later.
6) Reinstall the rack
Slide the rack back into the machine slowly. Watch the new roller as it enters the rail path. The wheel should track cleanly without jumping or catching.
Push and pull the rack a few times. It should glide better than before. If it still sticks, check for a second worn roller or rail damage. One bad wheel is common, but it is not always the only issue.
7) Test the movement
Load the rack lightly or leave it empty for the first check. Move it through the full travel range. Listen for scraping or clicking. Feel for smooth travel at both ends.
If the movement feels right, the install is complete. If not, inspect the mount again. A bent bracket or missing clip may still be part of the problem.
Common Mistakes That Waste Time
A good install can fail because of small errors. Watch for these.
- Installing the roller backward
- Forgetting a clip or retainer
- Mixing up left and right sides
- Leaving grit in the mount
- Forcing the part into a crooked holder
- Skipping the final hand-roll test
Most of these problems are easy to avoid. Slow work beats repeated disassembly. If the part does not seat cleanly, stop and inspect it.
How to Check Whether the Repair Worked
You want smooth rack motion after the new roller goes in. Use this quick check list.
- The rack slides without sticking
- The wheel turns freely by hand
- The mount stays tight
- No scraping sound remains
- The wheel sits straight in the track
If all five look good, your repair is in good shape. If one fails, revisit that area before you close up the unit.
When the Roller Is Not the Only Problem
Sometimes a new roller helps, but the rack still drags. That usually means another part is worn or bent.
Look for these extra issues:
- Rail damage
- Bent support arm
- Loose rack frame
- Buildup inside the track
- Broken clip or spacer
If more than one part looks damaged, fix the worst one first. Then test again. You do not want to replace parts twice because one hidden issue stayed in place.
Model Match Matters
The listed model numbers are your main guide for fit. Those models are ADB1200AWS, ADB1200AWW, ADB1500AWB, ADB1500AWS, and ADB1500AWW. If your unit matches one of them, WP99002947 is the part number you should compare against your old roller.
Keep the old part until the job is done. It helps with visual matching. It also gives you a backup reference if the new piece looks different in hand. A side-by-side check is the fastest way to avoid a bad match.

Maintenance Tips After the Install
A fresh roller lasts longer with basic care. Keep the track clean. Wipe spills before buildup hardens. Remove grit from the rails when you notice drag.
Inspect the rack during regular cleaning. A wheel that starts to wobble early may have a loose mount. Catching that early can prevent track damage. A small fix now beats a bigger repair later.
Here is a simple care rhythm:
- After each use: wipe visible debris
- Weekly: check rack movement by hand
- Monthly: inspect rollers and clips
- When needed: clean rails and support points
This routine is short, but it pays off. Smooth movement puts less stress on the whole rack system.
