Indeset w123 wash setting mind of its own?

Since having a go at 'repairing' my washing machine by removing some coins from the drainage prips in the rear the machine seems to have a mind of its own. Regardless of what setting I put the machine on, a few seconds after starting the wash it starts clicking round and will always go to setting 3. even if after it stops moving and I move it to the desired setting it moves on its own again. Once it was finished its washing the dial clicks once every second continuous until I switch the machine off. ANY ideas how to resolve?
