Introduction
A dishwasher float switch is a relatively inexpensive component compared with many other appliance parts. When the switch fails, replacing it is often one of the more affordable dishwasher repairs.
Understanding the typical cost of a float switch can help determine whether replacement is worthwhile compared with calling for professional service or replacing the appliance.
What This Means
The float switch is a small electrical component that works with the float inside the dishwasher to monitor the water level.
Because the part is simple and widely used across many dishwasher models, replacement switches are usually easy to find and relatively low in cost.
However, the exact price can vary depending on the dishwasher brand, model compatibility, and whether the part is an original manufacturer component or a universal replacement.
Typical Cost of a Dishwasher Float Switch
Most dishwasher float switches fall within a relatively narrow price range.
Typical prices include:
• Lower-cost aftermarket switches: approximately $10–$20
• Standard replacement parts: approximately $15–$35
• Original manufacturer parts: approximately $25–$50
Many replacement switches are compatible with multiple dishwasher models, which helps keep prices lower.
More specialized or brand-specific switches may cost slightly more.
Cost of Professional Replacement
If a technician performs the repair, the total cost may be higher due to labor charges.
Typical service costs may include:
• Service call fee
• Labor for diagnosis and repair
• Cost of the replacement part
In many cases, professional replacement can cost between $100 and $200 depending on location and service rates.
Because the float switch is relatively easy to access on most dishwashers, many homeowners choose to replace the part themselves.
Factors That Affect Replacement Cost
Several factors can influence how much the repair ultimately costs.
These include:
• Dishwasher brand and model
• Whether the part is OEM or aftermarket
• Local technician service rates
• Difficulty accessing the switch in the appliance
Older dishwasher models may also require more specific replacement parts, which can affect availability and price.
When Replacement Makes Sense
Replacing the float switch is usually worthwhile when the dishwasher is otherwise working properly.
Replacement is commonly recommended when:
• The switch fails electrical testing
• The dishwasher repeatedly overfills
• The dishwasher will not fill with water
• The switch is visibly damaged
Because float switches are inexpensive components, replacement is often the simplest solution when problems occur.
