I looked at this dishwasher yesterday. . Complaint: Dishes not getting clean anymore like they use to and food is left on the dishes. I stripped the dishwasher down and checked the impeller, made sure all the spray arms were clear, and sump was clean. Unit was very clean with little to no debris. Tested the unit and it appears all spray arms are turning and upside down cups in the top rack are quickly filling with water. Water is hot. Good wash action. I did find that the turbidity sensor failed twice in diagnostics but then made it through the test two other times.I did not ohm it out. Heating element is getting hot. If the turbidity sensor is failing, would this affect performance or make changes such as shortening or eliminating wash cycles? Would changing the turbidity sensor be the best course of action? Thank you for any advice.

I was informed by one time that you can unplug the turbidity sensor and it should run normally (without sensing). Have you tried it on this model? I know I did once when the unit would stall in the cycle and run for hours. Kept thinking it was a tun thermostat or control issue, when it turned out to be the sensor. Be sure the two lenses on the Honeywell sensor are clear and shiny. If they can’t perceive light beams well, the cycles will be sketchy. I have had good luck with a few doses of concentrated Lemi-Shine in a wash cycle, letting it circulate for a minute, then opening the door to allow the citric acid to do its thing. If all else fails, replace the sensor.
