Dishwashers last an average of eight to 10 years, although some last 15 years or more. Your appliance’s lifespan depends on usage, wear, water quality, and maintenance practices. The make and model may also influence dishwasher quality and longevity.

Routine maintenance keeps your dishwasher running efficiently and prevents premature replacement, keeping its overall operating costs low. Regular maintenance includes emptying the filter, cleaning the spray arms, descaling with dishwasher cleaner, and wiping down the door gaskets. Check your owner’s manual for manufacturer recommendations on caring for your appliance.

The time needed to repair a dishwasher mainly depends on the issue. Simple repairs, such as replacing door gaskets or unclogging the spray arm, may only take an hour or two. Replacing the motor, control panel, or other complex parts may need more involved labor over several hours. Most repairs shouldn’t take more than a day, provided your technician has the correct parts.
