Dishwasher Float Switch Replacement Cost

How much does a dishwasher float switch replacement cost?#

The overfill sensor in a dishwasher — the little float that shuts the water off once the tub is full enough — costs $90 to $145 to replace, typically about $118. It sits right on the base of the machine and is among the cheapest components anywhere in the appliance, so the visit is quick and the bill small. Set against the $400 to $1,200 a new unit costs installed, it barely registers. Because the part itself is so inexpensive, the diagnostic time to confirm it is often the largest single line on the invoice.

Dishwasher float switch replacement cost

• What it does: the float switch tells the control how much water is inside.
• Signs it is failing: overfilling, leaks, or a unit that will not fill.
• The repair job: freeing or replacing the float and testing the fill level.
• DIY or pro: often owner-fixable — the float is usually easy to reach.

Against a new dishwasher at $400–$1,200 installed, a float switch repair at $90–$145 is usually the cheaper fix — unless the dishwasher is already old or has other faults.

Pro note: a stuck float from food debris mimics a failed switch, so a tech frees and tests it before replacing anything.

Is replacing the float switch on a dishwasher worth it?#

On any sound machine this is an easy yes. At $90 to $145 versus $400 to $1,200 for a replacement, it ranks among the least expensive fixes going, and it cures two opposite complaints at once — a tub that overfills, and one that never takes water at all. Left unrepaired, the overfill fault can spill water onto the kitchen floor, so the modest outlay also heads off potential water damage that would dwarf the price of the part. Barring a genuinely worn-out appliance, this is money well spent.

Dishwasher Float switch replacement cost: FAQ#

How much does a dishwasher float switch replacement cost?#

Figure $90 to $145, typically about $118. The sensor is one of the cheapest components on the machine, sitting on the tub base, so the work is fast and the price is mostly labor and diagnosis.

Is replacing the float switch on a dishwasher worth it?#

Yes. At $90 to $145 against the $400 to $1,200 of a new dishwasher, the fix is easily justified, all the more so because it resolves either overfilling leaks or a tub that refuses to fill.

What makes the float switch fail on a dishwasher?#

The float sticks on debris, or the small contact beneath it wears out. The result is either a base that overfills and leaks onto the floor, or a cycle that never begins because the machine wrongly senses water already inside.

Can I replace a dishwasher float switch myself?#

It is a manageable do-it-yourself job, since the float and its contact sit at the bottom of the tub, though the wiring must go back correctly. Freeing a float gummed up with debris sometimes restores it with no new part at all.

How long does a dishwasher float switch replacement take?#

Plan on about 30 minutes: reaching the sensor under the tub, swapping it, reconnecting the wiring, and running a fill to confirm the water now stops at the right level.
