I would probably say the Hot Water Diaphragm has perished/pin-holed. The water that should push the plunger all the way out is getting through to the wrong side. Also check the condition around the plunger hole for signs of leaks which could be restricting the movement. The diaphragms are a common part to replace and are very cheap. Hope this has helped
