Sadly that is just never going to happen.
You might find some generous member willing to pay $500 for that washer, devote time and energy to fetching the thing, then storing until a future date; all to sell it on at same or lower price later on, but one has serious doubts.
First there is assumption washer is worth $500. Thus far it has not sold so either seller has unrealistic expectations (not uncommon) and or those potentially interested have their doubts.
Over years a number of NIB/NOS vintage washers, dryers and dishwashers have appeared on this site. Pink Maytag W&D set, various wringer washers, a Bendix combo unit and others. Some we know who purchased because new owners chose to share, other times said appliance simply vanished off face of earth with no further information (that Bendix or whatever combo unit for a start).
No offence intended but issue with suggestion is it takes a problem once had by seller (unloading that washer) and transfers it to a member. Latter will now be landed with problem of shifting that washer and hopefully making money in process or at least breaking even. Until it sells said potential member will have to store said washer so it will be sitting there haunting him or her until it's gone.
A member offering to collect and hold onto washer after it has been paid for until shipping can be arranged, now that is something more likely to happen. It's been done before by members for other members and worked out well.
