Identify what is actually being sold
New old stock, a floor display, an open-box return and a privately used appliance are different propositions. Ask why the machine was returned or removed, what has been checked and whether the answer is documented.
Obtain the full model and serial numbers before committing. Check for applicable recalls and the stated remedy using the CPSC database and manufacturer. A vague assurance that the brand has never had problems is not a substitute.
Inspect condition and completeness
Look for damaged racks, worn rollers, corroded areas, door alignment problems and missing baskets, mounting parts or hoses. Ask for the manual and installation inventory. A cosmetic scratch can be acceptable; an unexplained leak history or electrical damage needs a different response.
Do not rely on a display lighting up as proof that the machine fills, washes, drains and dries correctly. Ask what functional inspection was performed, by whom, and what happens if a fault appears after installation.
Make the price comparison complete
Add transport, installation, replacement connection parts and any required repair to the purchase price. Confirm the condition-specific return policy and warranty eligibility. A private sale may offer fewer practical remedies than a retailer-backed open-box offer.
A used model also needs to fit your opening and service area. A bargain that requires cabinet changes or unavailable parts can become the expensive option.
Know when to walk away
If the seller cannot identify the machine, explain a safety concern or clarify whether a recall remedy was completed, keep looking. Have installation and suspected defects handled by qualified people rather than improvising a repair to make a low-price purchase work.
