During the final spin cycle, water is leaking inside the machine

You have a problem with the pressure switch cutting in too early before all of the water has drained away from the outer drum

There is either an obstruction in the outlet pipe or pump which is not allowing the water to discharge fast enough.

The machine is then spinning with too much water left in the outer drum added to the water which is being expelled from the clothes equals leaking

Take the hose off the back of the machine and put it in a sink , make sure it is secure and do a rinse cycle

Watch the outlet and make sure it is a strong flow if it is weak then you have probably got an item of clothing stuck in the pipe from the drum to the pump and a strip down is required

One more thing there is a small plastic bottle attached to the back of the outer drum this has tube which leads to the pressure switch

Make sure there is no congealed soap in the Air Bell as it is called
