This hot water electric fire sometimes overheats and sometimes wont kick on but I have a sneaking suspicion that the slime may be insulating the thermostat.
Answers: Found this in the reliance marine heater company info bulletin. This is from at hand site. Have had same problem within past and hold changed out anode rod. Your right on the thermostat, check out source and follow the instructions. From Master Plumber. Good luck.
If your hot water have a greenish or bluish color to it, if there is slime or greenish/bluish particle when you flush the heater, this is an indication you may own aluminum hydroxide forming in your hose heater.
Aluminum hydroxide forms when the pH of the hose is incompatible with the protective anode rod. There are two types of anode rods used within water heaters. The Aluminum rod is used contained by water near a pH less than 7.5 and the magnesium rod is used within water near a pH over 7.5.
The anode rod is normally locate over the water and is the "metal plug" within one of the openings. The aluminum rod have a smooth top and the magnesium rod has a bump contained by the middle (about the size of half a marble).
The incompatible impulse manifest itself by making a rumbling noise, bumping crash or other type sounds coming from the heater when the burner is on. There can even be greenish to bluish slime come out of the hot sea supply. See tech. bulletin 14 for more information, including treatment: click here to view Technical Bulletin 14
