If your machine does not heat, check the following.
Fill the water reservoir with non-purified water or softened (without calcium and magnesium) water. Distilled or purified water may not allow the machine to heat. if you experienced a lot of water on the counter and the aforementioned resolves the issue.
If your machine is still not heating, check the following.
Unplug the machine. Remove the water reservoir. Lay your machine upside down. Remove the 4 screws holding bottom cover. Depress the safety switch button (usually red in color). Examples are shown below.
If it depresses and you feel a click, then test the machine. Test and stay near machine to make sure the gauge does not exceed 1.3. If it does, then the pressurestat (Heating element controller) has a lot of limescale causing it to stick. The machine would need to be descaled and the pressurestat would need to be replaced.
