water light flashes now and then

[gibby]

Mine has a tendancy to flash on every now and then too. I was concerned about it at first but it's been going on for about 18 months now so I guess it would have overheated by now had there been a problem and the temp gauge is always constant. I seem to find that it never comes on for ages then suddenly it'll flicker a couple of times in one journey.

mine seems to flash when you boot it and then the temp reading goes right up but then it will go back down to the middle position!

But your water level is ok ?  I'm wondering if your water level is just enough so when you boot it the water in the expansion tank slops about below the minimum mark near the sensor which does it's job and says you're low on water. Just a thought.

its right up to the max mark! will see how it goes, i may just replace the sensor near the head? will get me manual out! aka bible! lol
