Most dishwasher repairs land somewhere between $120 and $430 dollars, though the exact cost depends on the problem. Draining failures, leaks, heating issues, and electrical faults tend to make up the majority of service calls. Because dishwashers rely on pumps, valves, heaters, and sensors working together, symptoms often appear suddenly. A dishwasher that stops mid cycle, runs without spraying, refuses to drain, leaves dishes cold and wet, or leaks from the door all point to specific failure points that carry distinct price ranges. Knowing what each symptom typically means makes it easier to estimate the cost before calling a technician.
| Problem Type | Common Causes | Typical Symptoms | Cost Range |
|---|---|---|---|
| Leaks | Door gasket, inlet valve, sump seal, spray arm damage | Water under door, puddles, slow seep | $90–$320 (up to $550 for tub leaks) |
| Not Heating | Heating element, thermostat, control board | Cold dishes, long cycles, poor drying | $150–$430 |
| Spray/Wash Problems | Circulation pump, diverter, clogged spray arms | Quiet wash, stuck-on food, humming pump | $25–$420 |
| Electrical/Startup Failures | Latch sensor, control board, thermal fuse | No response, random shutdowns | $90–$500 |

Cost to Repair Dishwasher Leaks
Dishwasher leaks can come from worn door gaskets, cracked inlet valves, loose sump seals, or damaged spray arms. Symptoms include water collecting under the door, puddles forming only during the wash stage, or a slow leak that leaves damp flooring after longer cycles. Door gasket replacement typically stays on the lower side of repair costs, often between $90 and $160 dollars. Inlet valve or sump leaks usually run between $180 and $300 dollars, sometimes reaching $320 dollars on certain brands. Leaks coming from the tub or internal plumbing are less common but sit toward the highest end of the range, often between $300 and $550 dollars depending on material and access.
Cost to Repair a Dishwasher That Is Not Heating
If the dishwasher completes cycles but dishes feel cold, stay wet, or show streaks of detergent, the heater circuit is likely at fault. Cold wash symptoms often come from a failed heating element, a drifting thermostat, or a control board that is no longer sending power to the heater. Heater element replacement commonly falls between $150 and $280 dollars, though some high output elements reach $300 dollars. Control board problems sit higher, usually in the $250 to $430 dollar range, and certain premium models can reach $480 dollars. Many owners first notice extended drying times or cycles running longer than usual as early signs of heater trouble.
Cost to Repair Dishwasher Spray or Wash Problems
Dishwashers that run quietly without spraying, leave food stuck to dishes, or produce a dull humming sound usually have a circulation pump or diverter issue. These repairs vary widely in cost because circulation pumps differ by brand. Most fall between $200 and $350 dollars, though some integrated pump-motor assemblies reach $380 to $420 dollars. Spray arm replacement is cheaper, often between $25 and $70 dollars, especially if the arm is cracked or jammed by debris. A machine that starts washing but suddenly stops spraying halfway through the cycle often signals a failing pump motor or obstructed sump area.
Cost to Repair Electrical or Start Up Failures
Some dishwashers show symptoms like no lights, no response when pressing the start button, or cycles that stop without explanation. These issues typically involve the control board, thermal fuse, or the door latch sensor. A worn latch can cause the dishwasher to shut off randomly or refuse to start at all, and replacement tends to stay near the lower end of repair costs, usually around $90 to $160 dollars. Control board repairs land near the upper range, often between $250 and $430 dollars, with certain models reaching $500 dollars.
When Repair Makes Sense
Dishwashers under ten years old are usually worth repairing if the problem involves a pump, heater, hose, or gasket. These parts remain affordable and accessible. Once the machine is older, or when several high cost failures occur at the same time, replacement becomes more practical. Still, many homeowners find that a single targeted repair can restore several more years of reliable use. Click here to learn about how long your dishwasher should last.
