How much does a dishwasher diverter valve replacement cost?#
Replacing the diverter valve on the machine runs $115–$220 ($168 is the usual figure). The diverter valve is what handles running a full wash-and-dry cycle. When it fails, dishes coming out gritty or still wet is usually the first clue, and on a dishwasher that is not a fault you can safely ignore for long. Where a given quote lands depends on the brand, the part quality, and how buried the component sits. The valve is inexpensive; most of the quote is the labor to reach it, disconnect the supply, and test for leaks afterward. Against $400–$1,200 for a new dishwasher, that keeps a repair the cheaper move on a unit that is otherwise sound.
Dishwasher diverter valve replacement cost
- What it does: the diverter valve routes the wash water between the upper and lower spray arms.
- Signs it is failing: only one rack getting clean, or a grinding from the sump.
- The repair job: replacing the diverter motor and seal and testing both arms.
- DIY or pro: usually a technician job at the base of the tub.
| What you pay for | Typical cost |
|---|---|
| Part plus basic labor | $115 |
| Typical repair | $168 |
| Premium part or hard access | $220 |
| A new dishwasher, installed | $400–$1,200 |
Against a new dishwasher at $400–$1,200 installed, a diverter valve repair at $115–$220 is usually the cheaper fix — unless the dishwasher is already old or has other faults.
Pro note: a tech clears the sump of glass and debris while in there, since that is often what seized the diverter.
Is replacing the diverter valve on a dishwasher worth it?#
On a newer or premium dishwasher, replacing the diverter valve is worth it — $115 to $220 is well under the $400 to $1,200 a new one costs, and a unit from Bosch or Miele is worth keeping in service. With a sink of dishes piling up, a scheduled repair beats limping along or shopping in a hurry. The job stops making sense only on a basic unit past about 10 years, where the repair starts to rival the price of a replacement and other parts are wearing out too.
