Welcome to JA. My name is***** am a fully qualified vehicle technician with over thirty years in the trade. I will be happy to assist you today. Hopefully we can get this resolved quickly.
You will receive an offer of a phone call by the system, this only needs to be accepted if you wish to speak to me, I can otherwise continue to answer your questions via the thread.

It is very possibly the water pump, it is quite common for the impeller blade on the pump to come loose  and spin on the water pump shaft, so that even if the shaft is spinning ok, the pump is not actually pushing the coolant around the system.

This is the most likely reason for the coolant not circulating. Once the old pump is removed if there is a problem with it this should be easily detected.

You do not mention the engine size but it is quite common for the 1.4 engine to have problems, and if the coolant pump is replaced then the timing belt should also be replaced.

Other causes of overheating can be the head gasket, but the coolant would in this case still circulate.

I hope this answers your question but I want you to be 100% happy with the answer so do please feel free to ask any further details by replying to this thread.
