Not much you can do but take it to a laundromat and use a large front loader.

One of the best pieces of advice I have read about washing bedding too large for even a FL to handle, is to wash it yourself in a bathtub, rinse it well then transfer to the washer to spin out the water. That beats going to a laundromat and putting your bedding in a machine that someone else has taken some nasty things there to wash.

Yea, not much you can do but what's been said above. I used to put our king size blankets, comforters, duvets, quilts, etc...in the bathtub and stomp on them with my feet for a while, let soak for an hour, then let the water out and rinse, with more stomping on them. We've since moved down to a queen bed and things fit in our Speen Queen top loader now.

I have plenty of laundromat experiences, but armjim is right--the gross things people wash at the laundromat...plus our laundry always came back with the unpleasant smell of other people on it. Eww. I still take pillows there (not during covid) to be washed, but I chemical bomb them there and dry the #%$& out of them on mega hot at home for hours. Still not ideal, but it's either that or replace pillows every few months.

But if you have a well maintained laundromat, it can be a good experience.

Sorry this happened to you. I hope your beloved GE washer is alright.

King size anythings should not be washed in a residential washer no matter how big the washer is. Residential washers are not built to handle the enormous weight of these wet items no matter what the manufacturer says. Minimally, you'll end up decreasing the life of the machine, or worse you'll end up with a broken machine.

A lightweight down King comforter fits in my Maytag 4.7 cu ft. But, any ONE item isn't going to spin well in it. I have to offset by adding a couple of clean towels - have a stack of those, old, in the garage. DH uses them washing cars.

I have a heavy 5x7 cotton bathroom rug that I can wash quite easily but only if I add the towels, just two is enough to balance the weight of rug wet and accomplish a smooth spin.

Same with heavy mens work type jeans. I can wash 3 pair, 4, even 5. I can't wash 2 and expect a smooth transition through cycles. Sometimes less isn't better ;0)

I’ll agree with the one-or-two-items comments. I can’t wash 2 smallish area rugs in my washer. I have to add 2 or 3 towels with them.

Don’t have room to add anything with your king size bedding? Then your washer isn’t big enough to handle the bedding.
