This is the front switch which rotates to set the programme, and pulls out/pushes in to switch on/off.
When pulling it to switch on, the switch broke in my hand, and the cap of it came away, revealing a broken plastic part beneath. That part had a little projection which looked as if it should click into a corresponding small hole in the cap.
However, I could not fit it back, because the plastic part beneath had broken. My efforts only resulted in the loose broken part falling down inside a little way.
Can I get a replacement for the broken part, and is it practical to replace it myself?
