My Miele washing machine washes as per normal, but when the dial gets to "Rinse Hold" the machine stops and won't move onto the spin cycle.
To get around this I manually switch the machine onto spin to finish.

Is this problem an easy fix or Is the machine on the way out (cost more than It's worth)

I too have a Miele washing machine - it also has a Rinse Hold - some washing programmes take the machine to rinse hold in an attempt to prevent creasing - other programmes do not.

A clue to your situation is the word "hold" - progress is held suspended until the operator is ready for things to progress.

Your machine does not require a fix and neither is it on the way out. You would do well to read the operating instructions.

Rinse Hold is a feature - not a fault.

Happy Washing..., January 2016
