There are a few possibilities as to why your washing machine won’t drain all the water. For example, it may have a clogged drain hose or a broken pump. A broken lid switch or belt could also be to blame. Sometimes it may be as simple as a jammed hose, but whatever the reason, the water will need to be drained from the washing machine before the problem can be diagnosed.
If you suspect that your washing machine drainage issue is due to a blocked drain outside, you will need to investigate whether this is something that you or your local water sewerage company are responsible for. If it is the company who is responsible, you will need to get in touch with them to get help.
