Best Time to Buy and Install a Dishwasher: Seasonal Savings Guide (2026)

Q: What is the best time to buy a dishwasher?

The best time to buy a dishwasher is Black Friday (late November) when major brands discount 20-40%. Memorial Day (May) is the second-best opportunity at 15-25% off. January is good for clearance pricing on prior-year models (10-20% off) combined with slow contractor season for installation savings.

Q: What month is cheapest for dishwasher installation?

January and February are the cheapest months for dishwasher installation. Contractors are at their lowest demand point after the holiday season, meaning better availability, faster scheduling, and sometimes negotiable rates. May through August is peak renovation season - expect 2-4 week waits and less flexibility on pricing.

Q: When should I replace my dishwasher?

Signs it is time to replace: the unit is 10+ years old, control board has failed (repair often costs 60%+ of replacement cost), leaking from the door seal, visible rust on the interior tub, not draining despite cleaning (pump failure), or needing repeated repairs within a 12-month period. If the appliance is under 5 years old and has a single mechanical failure (pump, door latch), repair is usually the better value.

The best time to buy is Black Friday (November) when major brands discount 20-40%. The best time to book installation is January-February when contractors are slow. Combine both and save $300-600 total.

Contractor Pricing by Season

January-February

BEST

Contractor slow season. After the holiday rush, demand drops significantly. Better availability (often same-week booking), and some contractors will negotiate on flat-rate jobs during slow periods. Temperatures are low in many markets, reducing renovation activity.

March-April

Rising

Pre-renovation season ramp-up. Homeowners start booking spring projects. Availability still reasonable but tightening. Rates start climbing as demand picks up.

May-August

AVOID

Peak renovation season. 3-4 week waits are common in busy markets. Flat rates are at their highest. No discounts. If your dishwasher dies in June, you may still need to book in this period - get 3 quotes and be patient.

September-October

Moderate

Slowing down after summer. Reasonable availability, competitive rates. Not as cheap as January but better than summer.

November-December

Improving

Contractors become available again as renovation season winds down. Holiday period means some homeowners delay projects, creating availability. Good option if you bought on Black Friday and want quick installation.

The Strategic Plan: Maximizing Savings

If your dishwasher is still working but aging, use this plan:

October

Start tracking prices on the models you want. Set price alerts on CamelCamelCamel for Amazon, or check Home Depot/Lowe's apps.

November

Buy during Black Friday. Deals start early November now - the best models often sell out before actual Black Friday. Budget $700-900 for a solid mid-range Bosch, Samsung, or LG.

November-December

Store the appliance if needed. Keep it in the original box. Lay flat if possible. Label the front.

January

Book the installer. Search Angi, Thumbtack, and local appliance stores. Get 3 quotes. Confirm whether haul-away and any parts are included.

January-February

Get the installation done. Ask the installer to haul away the old unit as part of the service.

Total savings using this plan vs. emergency summer purchase: $300-600

When You Can't Wait: Signs a Dishwasher Is Beyond Repair

!Control board error codes requiring board replacement (often 60%+ of unit cost)
!Visible rust on interior tub walls
!Unit is 10+ years old with multiple recent repairs
!Second breakdown within the same 12-month period

If your dishwasher fails in peak season (May-August), you may still need to replace it. Get 3 quotes quickly and book the fastest available installer at the best rate you can find.

When should I replace my dishwasher?

Replace if: the unit is 10+ years old; control board has failed (repair often costs 60%+ of replacement); leaking from door seal; visible interior rust; not draining despite cleaning (pump failure); or repeated repairs within the same year. Repair if: under 5 years old with a single mechanical failure (door latch, spray arm, pump on a quality unit) where repair costs under 50% of replacement. A new Energy Star dishwasher is roughly 30% more energy-efficient than a 10-year-old model.
