A few thoughts… I probably would have tested the motor earlier in the process just to make sure it was OK before replacing the electronics. The fuse in the plug is high current but not sure what the rating of the PCB fuse is. If it is quite a bit lower than the plug fuse then it might be worth replacing??
@MyProjectBoxChannel2 күн бұрын
I was actually thinking that the fuse in the plug should be of a lower rating something like 5 to 10A. It's strange that philips opted for a 13 Amp plug fuse🤔. I had some old 5A "rewireable fuse wire", and I could of soldered that across the pcb fuse. But I don't want to encourage that practice. I did actually test the motor first, but I forgot to film it😂.

Yes the test tweezers are great for SMD component testing it does capacitors aswell😉. It was very reasonably priced, and pretty accurate too. I think I got mine on Ebay a couple of years back. It's called "ms8910 handheld smart smd tester" . Aliexpress and amazon did them too. I guess MOVs have their advantages, but I don't think it's necessary for a simple brush DC motor circuit, with just a bridge rectifier. It's great for very sensitive/ critical equipment and SMPSs. I watched a video of a newer Philips juicer repair, and now there's no MOVs on the pcb. So I guess the design is economizing/ cheaping out, and just a single speed aswell. So only the bridge rectifier and EMI LC-filter , that's it.

The purpose of the relay/contactor was the drop the load from the grid if there was a power failure, and gradually stagger the geysers from turning on. It's very difficult to turn the power back on if all the geysers have cooled down, and all the thermostats are clicked on. This is almost a dead short for the electrical grid.

There should be a fuse on the reverse diode at the light fitting between neutral and switched live. If someone decides to remove the sonoff and wiring at the switch side in the future, replacing it with a standard switch without realising that additional circuitry has been added to the light fitting, there will be a bang. The same outcome will happen if a diode fails short-circuit.

Yes, You can definitely use a 3A fuse, inline with the L, if you like. But the resistor has two jobs, it acts as a inrush current limiter, for when the capacitor initially charges up, and secondly as a fuse(If the capacitor failed). It should still work fine without the resistor, but the lifespan is increased, by adding a resistor. It puts less stress on the capacitor.

A Capacitors behaviour is different for AC current. With DC current it will change up, "kind of like a battery. With AC, it's constantly charging and discharging as the polarity reverses 50/60 times a second. This resulted in it passing current, kind of like a resistor. It's call impedance (a special type of AC resistance) so a capacitor will pass AC current, but with DC it will draw current when charging, and the current will stop when fully charged.😉👍 The the power in your house is alternating current AC, but a battery is direct current DC.
