You say it is not pumping water when hot, when that occurs remove large chrome screw and check the spindle inside is spinning you can use a small screw driver to release but do not use to much force could damage spindle, be mindful with hot water spillage and any electrical connections. Pump could be jamming because the system is sludged the sludge can work into a paste that is enough to seize the pump when hot.
