Hi everyone. I seem to have a problem with the temp reading on my truckmount. I turn on the ignition and the needle goes to 180 degees. When cleaning with it today the needle goes upto 240 degrees so it must still read the water temp but not correctly. Heres what i did to check it... I ran the water upto max temp and it read 240 so i turned of the heat source and the needle started to drop slowly but never went below 150 degrees but the water by then was freezing cold and had been for about 15 minutes. I was wondering if it was the heat sensor or a wiring prob. Any help and advise would be very helpfull.

which type and model?

Maybe unrelated, but I had a similar problem a few months ago. Turns out that scale build up had caused a blockage, which caused the sensor heat sensor to blow. The water wouldn't read hot at all, unless I pushed the nipple on the QC manually, when the gauge would shoot up.

To cut a long story short, the whole thing was caused by limescale, and me now sorting it quick enough.

Have you descaled?

Mine did this to and it turned out to be a faulty heat sensor

It was a faulty temp. sensor. Got as new one from Hydramaster £25 including delivery. All is well now again
