I am just replacing the heating element in our Bosch Classics washing machine WVF2042GB02. However I had to snip off the red thermostat wire before removing the heating element (attached picture shows wire in situ before snipping). I'm now not sure how to re-attach except by soldering it. The flat post the wire is wrapped round seems redundant as it's not connected to anything. All other thermostats for Bosch appear to have two wires and a plastic connector. Anyone encountered this and solved the problem?
