## Problem

The upper rack of your Whirlpool / KitchenAid / Kenmore dishwasher keeps collapsing on one or both sides. If you look at the back corners of the upper rack, you'll see a plastic wheel assembly with gear teeth — that's the **rack adjuster**. These plastic wheels are notorious for cracking after 3-5 years because they bear the weight of fully-loaded dishes.

## Which Part?

- **OEM number:** W10350375 (newest revision), W10712395, WPW10546503, W10195840, W10195839
- **Why so many numbers:** Whirlpool used different model-years with slightly different revisions. All fit the same slot.
- **Original Whirlpool:** $25-40 per adjuster (you need 2-4)
- **Third-party upgraded (POM glass-fiber reinforced):** $8-15 each

## Tools

None. The adjuster literally clips in by hand.

## Steps

1. **Pull the upper rack all the way out.** Keep pulling until it stops — the stop-clip is designed to release here.
2. **Lift the rack straight up** off the rails. It just lifts off.
3. **Find the broken adjuster.** It's at the back corner on each rail — a plastic wheel with gear teeth on top.
4. **Rotate the adjuster downward (toward the floor).** It unlocks from its track. Pull it off the rail.
5. **Clip the new adjuster onto the rail** in the same downward orientation.
6. **Rotate up until it clicks.** The teeth should mesh with the rail.
7. **Replace the rack.** Line up both sides, lower it onto the rails, test by sliding in and out.

## Why "Upgraded Material" Matters

The OEM part is PA66 nylon. When you load heavy casserole dishes on the upper rack, the plastic flexes repeatedly and develops micro-cracks. We recommend buying the **POM + glass fiber reinforced** version — 2-3× the tensile strength, and it costs the same.

## Still Not Working?

- If the rack still sags on one side, the **rail itself** may be bent. That's a $40-80 fix.
- If the adjuster won't stay clipped, make sure you're rotating it fully (it needs to click).

## 问题现象

惠而浦 / KitchenAid / 肯摩尔洗碗机的上层碗架老是一边或两边塌下来。你低头看一下碗架后方两个角，有个带齿轮的塑料滑轮——那就是**碗架调节器（rack adjuster）**。这些塑料滑轮用 3-5 年就容易裂，因为上层放满餐具时全是它在承重。

## 找对件号

- **OEM 编号**：W10350375（最新版）、W10712395、WPW10546503、W10195840、W10195839
- **为什么那么多号**：惠而浦不同年份改过几版，槽位都是一样的，可以互换
- **原厂件**：$25-40 一个（你通常需要 2-4 个）
- **升级材质（POM + 玻纤增强）**：$8-15 一个

## 工具

不需要工具。徒手就能装。

## 步骤

1. **把上层碗架整个拉出来**。拉到最外面，那个限位扣会自动松开
2. **把碗架直接往上抬**——就脱离轨道了
3. **找到坏的那个调节器**——在轨道两端角上，带齿轮的塑料滑轮
4. **把调节器向下转（朝地板方向）**，它就从轨道里脱开，然后拔下来
5. **把新的调节器以同样的向下方向扣到轨道上**
6. **向上转到咔哒一声**——齿轮应该咬住轨道
7. **装回碗架**：两边对齐，放回轨道，前后推拉几下测试

## 为什么要升级材质

OEM 原厂件用 PA66 尼龙。你在上层放砂锅之类的重餐具时，塑料反复受力，会有微裂纹。我们推荐**POM + 玻纤增强版**——拉伸强度是原厂的 2-3 倍，价格差不多。

## 还是不行？

- 如果碗架一边还塌，可能**轨道本身**弯了。那是 $40-80 的修法
- 如果新调节器扣不住，确认你转到位了（要听到咔哒声）
