An overheating situation can occur when
- the pressurestat is set too high
- the pressurestat has corrosion (buildup from limescale due to hard water or oxidation due to more purified water).
- The machine should be cooled and unplugged from the electrical outlet.
- Test in a GFIC outlet to see if it trips. This will show if the heating element was damaged due to lack of water in the boiler.
- Find and depress the safety thermostat.
- If used in plumbed in, what was the inbound water line pressure?
- If in tank mode, when was the last time the water softener was recharged as well as replaced? This may cause a decrease in water being pumped to refill the steam boiler once water is removed from the steam boiler through the hot water valve.
- If you remove the top lid and cover (4 screws) with the machine unplugged from the electrical outlet, please reset the safety thermostat.
- If knowledgeable on how to use a multimeter or continuity tester, the 2 wires need to be removed from the steam boiler heating element and tested for resistance or continuity at the heating elements posts.
