Dishwashers have the shortest average lifespan among major kitchen appliances, which makes the repair-or-replace decision tighter than for other appliances. Here's how to evaluate whether fixing your LG dishwasher is the smart financial move.
Dishwasher Lifespan Reality
LG dishwashers typically last 9–12 years, shorter than refrigerators (12–17 years) or ranges (13–18 years). This means the window where repairs make economic sense is narrower. A 6-year-old dishwasher has plenty of life left; a 9-year-old is approaching end of life. This context matters significantly when evaluating repair costs.
Cost Thresholds by Age
With new LG dishwashers starting around $550, the 50% repair threshold sits at approximately $275. Under 4 years: repair anything under $300 without hesitation. 4–7 years: repairs under $250 are a good investment. 7–9 years: only spend under $150. Over 9 years: minimal repairs only ($100 or less), and start shopping for a replacement.
Repairs That Always Make Sense
Door latch assembly (From $75), spray arm replacement (From $30), water inlet valve (From $80), and door gasket (From $80) are affordable repairs that extend the life of any LG dishwasher. These components are easy to source and install, and their failure doesn't indicate broader reliability problems. Even on older units, these repairs are worth doing.
Repairs That Require More Thought
Wash motor replacement (From $250) and control board replacement (From $200) are the most expensive common repairs. For dishwashers under 5 years old, these repairs are still cost-effective. For units between 5 and 8 years, they're borderline — consider the dishwasher's overall condition and repair history. For units over 8 years, these repairs often push past the point where replacement is the better value.
Don't Forget the Installation Equation
Replacing a dishwasher involves more than the purchase price. Professional installation adds From $150, and there may be costs for new supply lines, electrical connections, or countertop modifications if you change brands or sizes. Factor the full installed cost of a new dishwasher (typically From $700 for a comparable LG model) into your comparison, not just the sticker price.
