The flickmixer over my caravan sink does not work as in no water comes through whether it is on 240 volt or 12 volt pump. However, it works as normal over the vanity basin and in the shower. Is this a sticky washer/valve and can it be replaced cost effectively without replacing the whole tap?

It is most likely to be a sticky valve. I have had the same problem with the exact same model.

You can remove the valve from the tap and but a new one from the hardware store.

Typically, the top of the tap is held on with an screw that requires an allen key. Loosen this and remove the top of the tap. After that you should be able to remove the assembly holding the valve in place using a tap spanner set. You can pick up a set for less than $10. Pull the old valve out and replace it with the new one.
