Name the symptom before you name the trade
Almost everyone reaches for the wrong trade with these two appliances, and the wrong trade means a wasted call-out fee. A dishwasher is not a plumbing job, and a dryer is not an electrical job — both are appliance repair. The plumber and the electrician own the connections in the wall, not the machine.
Before you book anyone, three questions sort out who — or whether — to call:
- Is it under warranty? If yes, the brand decides who touches it. Skip to the authorized servicer, because an independent repair can void the rest of the coverage.
- What exactly is it doing? “Won’t heat,” “won’t drain,” “won’t run,” and “leaking” are four different problems that route to four different fixes. Describe the symptom, not just “it’s broken.”
- Can a five-minute check settle it? A dishwasher that won’t drain and a dryer that won’t heat are, more often than people expect, a clog you clear yourself or a vent someone cleans — not a repair at all.
Get those three right and you avoid the two classic mistakes: paying an independent tech to void your warranty, and paying an appliance tech a diagnostic fee to tell you the vent was clogged.
Who to call, and who not to
The trade is appliance repair. Here’s who owns what, and the two boundary trades people wrongly call first.
Under manufacturer warranty: the brand’s authorized service line. Samsung, LG, Bosch, Whirlpool — searches for those brand names next to “repair” are really warranty questions. While the unit is covered, you must use the brand’s authorized servicer, or an unauthorized repair can void the remaining warranty. Call the number in the manual or on the manufacturer’s site, not the first local ad. Check the paperwork, too, because major components sometimes carry longer coverage than the base warranty.
Out of warranty: an independent appliance repair technician. Once coverage has lapsed, an independent is usually faster and cheaper for the same fault, and you’re free to choose one. This is the authorized-versus-independent split, and it flips entirely on that warranty date.
Not a plumber, for a dishwasher. A plumber owns the water supply line and the drain plumbing in the wall and under the sink. The dishwasher’s own pump, inlet valve, float, and control board are appliance repair. A plumber will decline “my dishwasher won’t drain” — unless the actual problem is the sink drain or disposal it shares, which is the one genuine overlap.
Not an electrician, for a dryer. An electrician owns the 240-volt outlet and the circuit. The heating element, thermal fuse, motor, and belt are appliance repair. Call an electrician only if the outlet is dead, the breaker trips repeatedly, or nothing on that circuit works — the wiring, not the machine.
A home warranty policy changes the order. If you carry one, call the policy before you book anyone; most require their own contractor and will refuse a claim if you called your own. This is the same appliance-versus-plumber tangle that catches people with a fridge that stops cooling or leaks, and it’s the single most common version of the site’s founding complaint — every trade insisting it’s not their job collects the rest of the loops and the script that ends them.
The dryer that won’t heat is usually the vent, not the dryer
This is the routing insight worth the whole page. “My dryer won’t heat” splits into two completely different jobs, and telling them apart saves you money and, occasionally, a house fire.
The drum turns, there’s some heat, but clothes take two or three cycles and come out very hot. That is a clogged exhaust vent, not a broken dryer. Lint packs the duct, the hot moist air can’t escape, and the load can’t dry. The fix is a dryer vent cleaning service — its own trade, not an appliance repair. And it is a safety issue, not just an efficiency one: Fixr cites that 34% of home dryer fires are caused by failure to clean the dryer, adding up to roughly 2,900 dryer fires a year. Fixr prices a vent cleaning at $100 to $200, national average $150, and clearing a specific clog at $100 to $200.
No heat at all, with airflow that seems normal. That points back at the appliance: a failed heating element or a blown thermal fuse on an electric dryer, or an igniter or gas valve fault on a gas dryer. That’s the appliance repair technician. Fixr prices a heating element replacement at $150 to $250. One trap worth knowing: a thermal fuse very often blows because the vent was clogged, so a good technician clears the vent as part of the fix. Replace the fuse and leave the clog and you’ll be back where you started within weeks.
So the order is: clean the lint screen, check the vent flap outside actually opens, and feel whether there’s airflow. Poor airflow with hot clothes is the vent. No heat with normal airflow is the element. Two symptoms, two trades.
The dishwasher that won’t drain is often a clog you can clear
The other big false alarm. “My dishwasher won’t drain” is one of the most common calls, and it’s one of the most common ones you can fix yourself in ten minutes.
Work through this before booking anyone:
- The filter. At the bottom of the tub, usually a twist-out cylinder. A filter clogged with food and grease is the single most frequent cause of poor draining. Pull it, rinse it, put it back.
- The garbage-disposal knockout plug. If your dishwasher drains into a garbage disposal that was recently installed, check whether the installer left the knockout plug in the disposal’s dishwasher inlet. It’s a solid plug that must be punched out during installation, and forgetting it blocks all drainage — a very common miss after a new disposal goes in.
- The drain hose. Make sure it isn’t kinked behind the machine, and that the high loop or air gap under the sink is clear.
If it still won’t drain after those, it’s a drain pump or a control fault, and now it’s an appliance tech. Fixr prices a “won’t drain” repair at $50 to $400 and a pump repair at $100 to $250. But run the free checks first — a lot of technician invoices for “won’t drain” are a service fee to clean a filter you could have cleaned yourself.
What repairs cost, and sanity-checking the quote
Hold any quote against Fixr’s ranges and ask for the failed part in writing.
For dryers, Fixr puts typical repair at $100 to $200 with a national average of $150, and the full range from $50 to $450. The diagnostic fee runs $50 to $80, usually credited against the repair. Common parts: a heating element at $150 to $250, a motor at $250 to $450.
For dishwashers, Fixr puts typical repair at $100 to $300 with a national average of $200, and the full range from $50 to $600. The diagnostic fee runs $50 to $75. Common jobs: a control panel at $150 to $350, a pump repair at $100 to $250.
Hourly labor sits around $50 to $100 for both. A quote well above these ranges on a standard freestanding unit needs a specific reason, and that reason — the named component — should be on the invoice before you approve the work. If a number feels wrong, the same test applies as to any home-repair quote: honest ranges for common jobs and the questions that expose a padded one.
Repair or replace: the 50% rule
The math is simpler for these than for a fridge, because replacement units are cheaper. The rule of thumb: if the repair costs more than about half the price of a new unit, and the appliance is past about half its expected life, replace it.
Dishwashers tip toward replacement quickly. A new dishwasher is only $400 to $700 at Fixr. That means a $150 to $350 control panel or a pump job on a dishwasher that’s already eight or ten years old is pushing past the half-of-new line, and a new machine resets the clock with a warranty. Cheap fixes — a filter, a door seal, a drain hose — are worth it at any age.
Dryers lean toward repair. A new dryer runs $400 to $2,000 at Fixr, and dryers are mechanically simple and long-lived, so the half-of-new threshold is much higher. A $150 heating element or a $150 vent cleaning is almost always worth doing. A $250 to $450 motor on a dryer past fifteen years is the genuine judgment call — that’s where the 50% rule earns its keep.
The one thing that overrides the arithmetic is the vent-cleaning case, because that isn’t really a repair-or-replace question at all — it’s maintenance that also happens to prevent a fire, and it’s worth doing regardless of the dryer’s age.
If you rent
If the dishwasher or dryer came with the rental, it’s the landlord’s appliance and the landlord’s repair. Report the fault and let them book the service — and note that if the appliance is still under manufacturer warranty, the landlord has to route it through the brand’s authorized servicer too, so don’t call your own person and risk voiding it. If it’s an appliance you brought in yourself, it’s yours to maintain and repair.
One thing to flag in writing regardless of who owns the machine: a clogged dryer vent. Lint buildup in the exhaust is a fire hazard for the whole building, not just your laundry, and vent cleaning is a maintenance item a responsible landlord should handle promptly. If the landlord stalls on a genuine safety issue like that, the escalation ladder for a landlord who won’t fix things runs from written notice to code enforcement.
