Jeffrey L Franklin , WI March 28, 2016 Appliance: Electrolux Dishwasher EWDW6505GB0B Electrolux Dishwasher Ewdw6505gb0b: E02. How to replace Sensor. I bought a replacement turbidity sensor and swapped it out. Very simple and straightforward. However there is one trick to be know. When I pulled out the bad sensor, drain water spilled from the hole and trickled into the motherboard housing! I then had to pull out the board and check it for damage. I left it in front of a box fan for 5 hours just in case. All is well. 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
