Furniture sliders?

I had furniture/ appliance sliders under my washing maching. my washer sits at my back door and i need sliders under the washer to get in and out of the back doo. had beed working fine for 5 years until painter came to paint, moved the washer and mnow it does not slide anymore. i'ver replaced the sliders and waxed the floor, still wont slide. its very hard to move now. any ideas?

Furniture sliders?
I´m not to sure but it might have something to do with the weights inside the machine they might have dropped when the machine was moved
