Should I Repair or Replace My Dishwasher?

When to Repair Your Dishwasher

Dishwashers are workhorses — they handle hot water, detergent, and food debris every day. But many common problems are affordable to fix, especially on units under 7 years old.

Repairs That Are Usually Worth It

• Door latch ($50-$150) — If the door won't close or stay latched, this is usually an easy fix.
• Spray arm replacement ($50-$100) — Clogged or broken spray arms are cheap to replace and restore cleaning power.
• Drain hose or filter cleaning ($75-$150) — Often the fix for drainage issues is just clearing a clog.
• Heating element ($100-$200) — If dishes aren't drying, this may be the culprit. Still cheaper than a new unit.

When to Replace Your Dishwasher

Dishwashers have shorter lifespans than other major appliances, so the math tips toward replacement faster:

Signs It's Time for a New Dishwasher

• Pump failure — A new pump plus labor runs $150-$350. On a dishwasher over 7 years old, that's getting close to replacement territory.
• Control board issues — Electronic components on modern dishwashers are expensive and often indicate broader electrical problems.
• Rust inside the tub — Once the interior starts rusting, it's only going to get worse. Time to replace.
• Persistent leaks from the tub — Small seal leaks are fixable, but if the tub itself is cracked or corroded, repair isn't practical.

Dishwasher Maintenance Tips

Want to extend your dishwasher's life? Here's what actually matters:

• Clean the filter monthly — Most modern dishwashers have a removable filter that traps food debris. Clean it regularly to prevent clogs and odors.
• Run hot water before starting — Run your kitchen faucet until the water is hot, then start the dishwasher. This ensures it starts with hot water for better cleaning.
• Don't overload — Overcrowding blocks water flow and stresses the spray arms.
• Use the right detergent — Pods or powder designed for dishwashers. Never use dish soap — it'll flood your kitchen with suds.

Dishwasher Repair FAQs

Is it worth repairing a dishwasher?

For minor stuff like a clogged drain, bad door seal, or a faulty float switch, absolutely. Those are cheap fixes. For pump replacements, control board issues, or motor failures on a unit over 8 years old, you're often better off replacing.

When should I replace my dishwasher instead of fixing it?

Replace it if the tub is cracked, if water is leaking from somewhere you can't easily access, if the motor or pump has failed on an older unit, or if the repair quote pushes past 50% of a new dishwasher's cost. New dishwashers run $400 to $1,000+ for decent models.

How much does dishwasher repair cost?

Most dishwasher repairs cost $150 to $500. Drainage problems and door seal replacements are on the cheaper end. Pump replacements, control boards, and motor work climb higher. Add a $75 to $150 service call fee on top.

How long do dishwashers usually last?

Around 9 to 12 years on average. Built-in models tend to outlast portable units, and brands with simpler controls (less circuit board, more mechanical) often last longer than feature-loaded high-end machines.

Is it worth fixing a dishwasher that won't drain?

Yes, almost always. A non-draining dishwasher is usually a clogged filter, a kinked drain hose, or a failed drain pump. Filter and hose issues are cheap or free DIY fixes. Even a drain pump replacement is reasonable, usually $150 to $300 with labor.
