How much does a dishwasher wash motor / pump replacement cost?#
A dishwasher wash motor / pump replacement typically costs $150 to $350, with most jobs around $250. The wash motor / pump 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. What decides the low or high end is part quality, access difficulty, and how much diagnostic time the fault demands. The motor is affordable — the cost is the teardown, since reaching it usually means pulling a rear or interior panel. Against $400–$1,200 for a new dishwasher, that keeps a repair the cheaper move on a unit that is otherwise sound.
Dishwasher wash motor / pump replacement cost
- What it does: the wash motor / pump circulates water through the wash cycle.
- Signs it is failing: loud grinding, a weak wash, or no circulation.
- The repair job: replacing the motor-pump and clearing the debris that caused it.
- DIY or pro: usually a technician job on most models.
| What you pay for | Typical cost |
|---|---|
| Part plus basic labor | $150 |
| Typical repair | $250 |
| Premium part or hard access | $350 |
| A new dishwasher, installed | $400–$1,200 |
Against a new dishwasher at $400–$1,200 installed, a wash motor / pump repair at $150–$350 is usually the cheaper fix — unless the dishwasher is already old or has other faults.
Pro note: a tech finds what shredded the impeller — glass or a bone fragment — so the replacement pump does not fail the same way.
Is replacing the wash motor / pump on a dishwasher worth it?#
On a newer or premium dishwasher, replacing the wash motor / pump is worth it — $150 to $350 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.
