If there is no circulation of water it could be that your water pump impeller has come off ,as they are plastic,or thermostat is not fully opening

If thermostat o.k , carry out a block test to check if head / gasket pressurising cooling system Or could try bleeding cooling system first for airlocks .

Thanks for that, water pump (new 2 years ago) appears to be ok as is thermostat. It looks as though system may be silted up, a clean through has been done and things seem better.
