Dishwasher Turbidity Sensor Replacement Cost

How much does a dishwasher turbidity sensor replacement cost?#

A dishwasher turbidity sensor replacement typically costs $100 to $200, with most jobs around $150. The turbidity sensor is what handles running a full wash-and-dry cycle. When it fails, dishes coming out gritty or still wet is usually the first clue, and on a dishwasher that is not a fault you can safely ignore for long. What decides the low or high end is the brand, the part quality, and how buried the component sits. Most of the quote is confirming the fault, since a drifting sensor and a bad board look alike at first. Against $400–$1,200 for a new dishwasher, that keeps a repair the cheaper move on a unit that is otherwise sound.

Dishwasher turbidity sensor replacement cost

• What it does: the turbidity sensor reads how dirty the water is so the cycle adjusts itself.
• Signs it is failing: cycles that run too short and leave dishes dirty, or far too long.
• The repair job: cleaning or replacing the sensor in the sump and testing a cycle.
• DIY or pro: a moderate DIY job at the base of the tub.

Against a new dishwasher at $400–$1,200 installed, a turbidity sensor repair at $100–$200 is usually the cheaper fix — unless the dishwasher is already old or has other faults.

Pro note: a tech clears the sensor window of film and grease first, since a fogged sensor misreads the water and fakes a fault.

Is replacing the turbidity sensor on a dishwasher worth it?#

Replacing the turbidity sensor pays off whenever the dishwasher is otherwise sound: $100–$200 beats the $400 to $1,200 of buying new, and it spares you delivery and haul-away on top. With a sink of dishes piling up, most owners would rather fix a Bosch- or Miele-tier unit than replace it; if instead it is past roughly 10 years and carrying other faults, put the money toward a replacement — a single fix rarely rescues a tired machine.
