There are several considerations. If this is the first time the quilt is being washed, I highly recommend using Synthrapol. Synthrapol suspends any unset dye particles in the water so they are washed away instead of settling into other fabrics.
A front-loading washing machine is fine. If you have a top-loader, it's best to stop the machine so the quilt does not go through the agitation cycle. Instead, hand agitate by pushing down on the quilt through the wash water. When done, advance to spinning. For rinsing, again do not allow machine agitation but instead hand agitate before spinning. Spinning is not hard on the quilt, but the agitators in top-loading washing machines are very hard on a quilt. Also, unless this quilt has been washed several times before and you are sure no colors will bleed, I recommend not allowing the quilt to soak. If there are any bleeding dyes, soaking can allow unwanted dye to settle in another fabric.
If the quilt is very large, you may want to take it to a laundromat. Here in the U.S., laundromats usually have at least one front-loading washer and their dryers are very large. Do not stuff a quilt into a home dryer if it is a tight fit; you can actually burn the quilt (not to mention damaging the dryer).
An alternative to machine drying the quilt is to lay it out on a large sheet. "Block" it (straighten edges and pin down to stay) and let a fna blow air over it if you are doing this inside. This probably works best if you have first been able to machine dry it to a damp stage and are able to pin it to carpeting. You would want to turn the quilt over periodically too. If you let the quilt dry on a sheet outside, *be sure* to cover the quilt with one or two sheets to prevent sunlight from fading the fabrics. It also prevents birds from decorating the quilt.
Never hang a wet quilt over clotheslines. The weight of the water in the quilt puts a lot of stress on the quilting lines and the fabrics. Drying flat on the ground is much better for the quilt.
