Miele c3 vacuum (Freehold LA1)

Over 10 years old and with issues.
I had a new mother board fitted but it did not stop the intermittent stopping and starting and difficulty with turning on. I bought a new switch but replacing it defeated me - there are YouTube videos but needed a particular screwdriver.
Oh and switch to retract cord does not work.
Once it gets started it does well.
So if you want a project- these are great machines. I’ve just bought a new version of same model.
You can have the vacuum cleaner and the new switch.
Fair use offer applies.
