As you say its quite old and a replacement would be a good idea but you may not be able to get it replaced before Christmas so a repair is probably a better option.

It could be a diverter valve issue which is more expensive.

Not many engineers are very keen to work on that model and you may have a problem finding one prepared to do a repair.
