| [title] Explaing my PCB-free quick-fix | |
| [* black] The PCB has a very simple functionality: if you press the toggle button, it turns on a relay to power the device. If you press the toggle button again, it will turn that relay off again, powering down the entire device. | |
| [* black] It also checks if the pump ever gets turned on (which means you are either tapping hot water or preparing a coffee). If you don't do that for a while, it will also turn off the machine. | |
| [* black] The first part, we can also easily do with a switch. It works again then, but if I forget to turn it off, it will stay on forever, eating a lot of electricity! | |
| [* black] The switch used in the device just sends a short pulse to the PCB (toggle). If you want to remove the PCB, you'll need to replace this with a switch that remains switched on until you turn it off again. | |
| + | [* black] CAUTION: if you follow my instructions, you are messing with main voltage circuits! This can be dangerous! So only continue if you understand what I've written above and you know what you are doing! |
