LG Dishwasher LDF6810BB: Help Unplugging the Turbidity Sensor

[fireman862]

I have the above listed LG dishwasher which is 5 years old. It's cleans, but not as well as it used to. I have checked all of the recommended places for blockages and other possible causes. I believe the sump assembly is starting to underperform, however, before I replace it I want to try unplugging the current turbidity sensor. I've downloaded the service manual for my dishwasher, but I don't clearly see the turbidity sensor. I do see the soil sensor, which is probably the same thing.

Questions:
1. Do I have to access the turbidity sensor plug from the bottom of the unit?
2. Does someone have a picture showing the sensor to be unplugged or able to provide me a written description of what to do?

Thanks,
John

You are correct. The turbidity and soil sensor are one in the same. I have attached a photo of the of it. Ignore the part on the left in the photo. I don't know why it's in the photo. It's for the upper / lower basket servo and is not related. The soil sensor connector is the smallest connector on the sump. Typically loss of wash performance would be caused by a lack of agitation / pump pressure from the wash motor. Also lower than normal heat, either entering through the water supply or the sump heater is not maintaining the proper heat level. The soil sensor, pcb & other less frequently occurring issues could effect the wash performance as well.

Thanks for the reply. It's very helpful.
Do I access this small connector by removing the unit, turning it upside down, and removing the cover as described in the service manual or can I access this connector through the bottom kick panel?

You will HAVE to remove the unit.
