My Mastermatic would fire (growl) blue smoke, when water was flowing K1 was burning and Temperature was below setting on Thermostat. Enough water had to flow to make the ignitor ignite and heat water, that's why Steamway hand tools had a pin hole in the copper supply line encased in the vacuum hose.So water was always flowing. Cooling down the coil to a tolerance and then heating it up. Never had a problem with over heating.
