I changed the Turbidity Sensor and the dishwasher now works great! The detailed notes on the review written on the f7-E1 error code written by David F from Austin, TX on September 14, 2021 were very helpful for me to have confidence in the repair to fix our dishwasher since we were seeing the same dirty dishes with soap remaining in the dishwasher and no heat. The video by the AppliancePartsPros.com expert was great to show me step-by-step how to change the turbidity sensor. The sensor was delivered very quickly as promised.
