What to do when your dishwasher stops working

A broken dishwasher usually means one of three things: water isn't entering or draining, the spray arms aren't rotating, or the door latch is stuck. Before you call a repair person, you can check a few things yourself—whether the drain hose is kinked, whether the filter is clogged, whether the door closes fully, and whether the control panel is actually on. Many dishwashers have a hidden reset button or a control lock that can be toggled off by holding a button for three seconds. If none of those work, you're looking at either a repair call or replacement.

The cost of repair versus replacement depends on what's broken, how old the machine is, and what a new one would cost. A repair call typically runs $150 to $300 just for diagnosis and a service visit, plus parts. A new dishwasher ranges from $400 to $1,200 for a standard model. If your machine is under five years old and the repair is under $400, repair usually makes sense. If it's over eight years old, a repair might buy you only a year or two before something else fails.

Key Takeaways

  • Most common dishwasher problems—clogs, stuck doors, broken spray arms—can be diagnosed by checking the drain hose, filter, and control panel before calling for repair.
  • A repair service call costs $150 to $300 for the visit alone, plus the cost of any parts that need replacing.
  • Repair makes financial sense if your dishwasher is under five years old and the repair estimate is less than half the cost of a new machine.
  • Older dishwashers are more likely to have multiple failures in quick succession, so replacement may be cheaper than repeated repairs.
  • Finding a repair person usually means calling local appliance repair shops, checking your dishwasher's warranty paperwork, or asking your plumber if they handle appliances.

How to find a repair person

Start with your dishwasher's warranty paperwork or the manufacturer's website, which often lists authorized repair centers in your area. Authorized repair people have access to the correct parts and know the specific model's common failures. If you don't have the paperwork, search online for "appliance repair near me" or "dishwasher repair [your city]" and call three shops to compare prices.

When you call, have your dishwasher's model number ready—it's usually on a sticker inside the door frame or on the side wall. Tell the repair person exactly what the machine is doing (not draining, not filling, making noise, leaking). Most shops will quote you a service call fee ($75 to $150) and tell you they'll call back with a parts estimate after they see it. Some shops charge the service fee toward the repair if you go ahead; others don't. Ask before they come out.

If cost is your main concern, ask whether the repair person offers a warranty on their work—most reputable shops offer 30 to 90 days on parts and labor. This protects you if the same problem comes back quickly.

Common repairs and what they typically cost

A clogged or broken drain pump is one of the most frequent failures and usually costs $200 to $400 in parts and labor. A broken door latch or seal runs $150 to $300. Spray arm replacement is typically $100 to $200. A failed control board—which tells the machine when to fill, drain, and heat—can cost $300 to $500 because the part itself is expensive and labor is involved in removing and reinstalling it.

Water inlet valve failure (the part that lets water in) usually costs $150 to $300. Heating element replacement runs $200 to $400. If the machine is leaking, the repair could be as straightforward as a $50 door gasket or as complex as a cracked tub that costs $400 to $600 to replace. The only way to know is to have someone look at it.

Deciding between repair and replacement

Use this rough calculation: if the repair estimate is more than 50 percent of the cost of a new dishwasher, replacement is usually the better choice. A $400 repair on a $600 machine tips toward replacement. A $250 repair on a $900 machine tips toward repair. Age matters too—if your dishwasher is over ten years old, even a $200 repair might not be worth it because the next failure could come within months.

Consider also whether you like your current machine. If it's been reliable except for this one failure, repair makes sense. If it's been noisy, slow, or unreliable for years, replacement gives you a fresh start and often better energy efficiency. Newer dishwashers use less water and electricity than models from ten years ago, which can offset some of the replacement cost over time.

If you're renting, check your lease before paying for any repair. Many landlords are responsible for appliance repairs, and paying out of pocket might not be reimbursable.

What to expect during a repair visit

The repair person will usually take 30 minutes to an hour to diagnose the problem, remove panels if needed, and test components. They'll then tell you what's broken and what it will cost to fix. You can say yes, no, or ask them to call you with an estimate if you need time to decide. If you say no, you'll pay the service call fee. If you say yes, they'll order the part (if they don't have it) and schedule a return visit, or fix it on the spot if they carry the part.

Most repairs take one to two visits. The first visit is diagnosis; if the part isn't in stock, they order it and come back. Some shops can get parts within 24 to 48 hours. During the wait, your dishwasher sits broken unless you arrange to have it picked up and brought back, which adds cost and time.

DIY fixes that sometimes work

Before paying for a service call, try these: remove and clean the filter at the bottom of the tub (it catches food and can clog). Check that the drain hose isn't kinked or blocked—trace it from the dishwasher to where it connects to your sink or garbage disposal. Make sure the garbage disposal is running if your hose connects to it; a full disposal can back up into the dishwasher. Look at the spray arms to see if food particles are blocking the holes; soak them in hot water and clear any debris with a toothpick.

If the door won't close, check the bottom edge for food or debris. If the control panel won't respond, try holding the "start" or "cancel" button for three to five seconds—many models have a control lock that can be toggled this way. If the machine fills but doesn't spray, the spray arms might not be seated correctly; remove them and reinstall them firmly.

If none of these work, you've narrowed down the problem and can describe it more accurately to a repair person, which can save time and money on the service call.

Frequently Asked Questions

How long do dishwashers usually last?

Most dishwashers last seven to ten years with normal use. Some last longer, some fail sooner. Age alone doesn't mean you should replace it, but it's a factor in deciding whether a repair is worth the cost. A machine at year nine or ten is more likely to have a second failure soon after the first.

Can I repair a dishwasher myself?

straightforward fixes like cleaning the filter or clearing a drain hose are safe to do yourself. Replacing internal parts like pumps, valves, or control boards requires disconnecting water lines and electrical connections, which can cause leaks or electrical hazards if done wrong. Most people should hire a professional for internal repairs.

What if the repair person says the tub is cracked?

A cracked tub usually means replacement, because the tub is the main structural part and a crack will only grow. Repair shops rarely attempt to seal or patch a cracked tub because it won't hold. This is one of the few repairs where replacement is almost always the only option.

Does homeowners insurance cover dishwasher repair?

Standard homeowners insurance does not cover appliance failure or breakdown. Some insurance policies cover sudden damage from a covered event like a fire or electrical surge, but not normal wear and tear. Check your policy or call your agent. Some retailers offer extended warranties or appliance protection plans at the time of purchase.

Should I repair a dishwasher that's still under warranty?

Yes—check your warranty paperwork first. If the machine is still covered, the manufacturer may pay for repair or replacement. Authorized repair shops can file the warranty claim for you. If you use an unauthorized repair person, you might void the warranty, so always check before calling someone outside the manufacturer's network.
