Water temperature gauge not working

[BMEC]

The gauge has suddenly stopped working but the flashing red light in the middle still works as normal. I suppose it could be the sensor or the gauge itself. Are there easy checks to tell where the problem is? It's a 1985 1.9 DG and it has never happened before.
