How to Troubleshoot & Replace Whirlpool AP6016738 / WPW10195039 Dishwasher Water Level Switch

The turbidity sensor fixed the long run time. Easy to replace thanks to your helpful video. Heater Assembly fixed the drying problem. Another easy fix thanks to your helpful video's. And last but least the water level switch. All three were faulted during the error code test. Now the dishwasher runs like new again. Thank You. 

Dishwasher was turning off 30-120sec after starting a cycle. I tried turning off power and resetting, didn't help. I then ran a diagnostic test and it was showing errors F6E4 F6E6 F8E1and F-E-, all of which I was able to find the cause except the last. I was prepared to order the different parts related to these errors but was distracted for a day or two. During this time, the dishwasher started running on it's own when the door was closed. I did more reading about this symptom and others stated the starting on it's own was related to a failed Electronic Control Board. I ordered here and replaced the ECB figuring the errors were a symptom of a larger issue and it was right. It took me about 20min to remove/install/replace all the necessary pieces through a video i found on here and it fixed the issue instantly. It's been running great for the last week. 

Replaced safety switch. 

I researched what could cause the problem, discovered it most likely was a sensor. I googled the make and model for parts and came across Appliance Parts Pros. Ordered the sensor and decided to also order the water level float lever, since it was next to sensor on the schematics shown on their website. Parts were shipped quickly! My husband had never done anything like this before and the website also gives you videos that show you step by step how to replace the parts. In less than 10 minutes he had the parts replaced and the dishwasher running!!! Appliance Parts Pros will now be my go to before a repairman!!! 

Initially I replaced lower door seal and water level switch, which may have helped but didn't solve it. Then leveled dishwasher which was tilting forward a bit. Also noticed rinse aid dispenser leaking rinse aid all the time which was causing foaming, so we emptied the dispenser and are not using rinse aid at this time. All of the above finally solved the problem, but not sure how much of the problem was caused by each fix. 

I installed a new float, switch, and rocker arm. That helped a little, but what made the difference was changing from pods to gel washing detergent. In hindsight, I should have tried that first. 

Float switch, bottom door seal, switch lever. Problem may have been actually due to high suds level because wrong soap was used. Video from APP was very helpful. 

Replaced a number of parts in the drain and switch assembly 

I replaced the fill valve and water level switch. Diagnostic mode indicated that it was a faulty level switch, but I wanted to replace the aging fill valve as well. I found the installation videos Very helpful. Works like a charm now! Thanks AppliancePartsPros.com! 

Replace float sensor and inlet valve.
