Dishwasher Leaving Dirty Dishes or Running Wrong Cycles? Maytag Turbidity Sensor 99002071 – Fix Wash Failure Fast
If your Maytag, Whirlpool, or KitchenAid dishwasher is leaving dishes dirty, running excessively long cycles, or not adjusting wash intensity based on load soil level, the turbidity sensor is the most common cause. In most Maytag and Whirlpool-built dishwashers, the turbidity sensor monitors water cloudiness in real time and signals the control board to extend or shorten the wash cycle based on how dirty the water is. When it fails, the dishwasher may default to a fixed cycle time, skip soil-sensing entirely, or produce consistently poor wash results regardless of detergent or load size. ⚡ Common failure point in Maytag and Whirlpool-built dishwashers. Part 99002071 is the genuine OEM replacement that restores accurate soil sensing and returns the dishwasher to full auto-cycle performance.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ QUALIFIER 1 — Dishwasher powers on and cycles run to completion
- ✔ QUALIFIER 2 — Water supply, spray arms, and wash pump confirmed working
- ✔ QUALIFIER 3 — Detergent dispenser opens and releases correctly
- ✔ ONLY problem is dishes coming out dirty, cycles running too long or too short, or auto-sense not adjusting

🔧 Common Symptoms
- Dishes consistently coming out dirty or with food residue despite normal loading
- Auto-sense or soil-sensing cycle running the same duration regardless of load
- Dishwasher cycle runs excessively long with no improvement in results
- Error codes related to water quality or sensor fault on the control panel
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this turbidity sensor restores full auto-cycle performance immediately.

While the lower dishwasher tub is accessible, inspect the spray arm nozzles for clogs and the wash pump filter for debris buildup. A clogged filter or blocked spray arm can mimic turbidity sensor failure and will reduce wash performance even after the sensor is replaced. Clean or replace both at the same time for best results.
⚙️ Installation
Skill Level: EASY — 15–25 Minutes. Disconnect power before servicing. The turbidity sensor is typically located on the lower tub near the sump area — remove the lower spray arm and filter assembly to access it. Disconnect the wiring harness, twist or unclip the sensor from its mount, install the new sensor, reconnect the harness, and run a test cycle to confirm auto-sensing is restored.

💡 Pro Tip
Before fitting the new turbidity sensor, wipe out the sensor mounting pocket with a damp cloth to remove any mineral scale or detergent residue. A dirty pocket can partially block the sensor’s optical window and cause the same poor-sensing symptoms to return even with a brand-new part. Takes 30 seconds and prevents a repeat repair.
