The safety thermostat, also known as a Klixon, is a temperature-sensitive switch that opens the circuit if the machine gets too hot. This is a crucial safety mechanism to prevent fires or damage to the machine. To check the safety thermostat, first, ensure the machine is unplugged and cool. Locate the thermostat, which is usually attached to the boiler or heating element. Use a multimeter to test for continuity. The thermostat should show continuity when the machine is cool. If it shows no continuity, it may have tripped. Some safety thermostats can be reset manually by pressing a small button on the device. However, if the thermostat trips frequently, it indicates an underlying issue that needs to be addressed, such as mineral buildup or a faulty heating element. A failing thermostat must be replaced immediately.

Similarly, the thermal fuse is a one-time safety device that blows and breaks the circuit if the machine overheats. Unlike the safety thermostat, a thermal fuse cannot be reset and must be replaced if it blows. To check the thermal fuse, locate it near the heating element and test for continuity with a multimeter. If there is no continuity, the thermal fuse has blown and needs replacement. A blown thermal fuse is often a sign of a more significant problem, such as a faulty heating element or a malfunctioning thermostat. Replacing the thermal fuse without addressing the root cause may result in the new fuse blowing as well. Therefore, it’s crucial to identify and fix the underlying issue before replacing the thermal fuse. Regular maintenance and descaling can help prevent overheating issues and prolong the life of these safety components. By ensuring that these safety devices are functioning correctly, you're not only protecting your machine but also ensuring your safety.

4. Pressurestat and Wiring Issues

The pressurestat in your Ascaso Steel Duo plays a vital role in regulating the boiler pressure and, consequently, the temperature. A malfunctioning pressurestat can prevent the machine from heating up properly. The pressurestat is a mechanical switch that turns the heating element on and off to maintain a consistent pressure level within the boiler. If it's not functioning correctly, it may fail to signal the heating element to turn on. To check the pressurestat, first, ensure the machine is unplugged. Locate the pressurestat, usually found connected to the boiler. Visually inspect it for any signs of damage or corrosion. If possible, use a multimeter to test the continuity across the pressurestat's terminals. With the machine off and cool, the pressurestat should show continuity. However, testing a pressurestat often requires specialized knowledge and equipment, as it involves monitoring the pressure levels within the boiler. If you're not experienced in this type of testing, it's best to consult a qualified technician.

Beyond the pressurestat, wiring issues can also cause heating problems. Loose or damaged wires can interrupt the flow of electricity to the heating element. Carefully inspect all the wiring connections inside the machine. Look for any frayed wires, loose connections, or signs of burning.
