I've had this soup maker for about 5 months. At the beginning I was ultra cautious when washing it and I studiously ensured no water got into the electrics. I stopped being so careful and then found that it wouldn't start its heating cycle without tripping the mains circuit breaker. Below is the process I followed to fix it.
First prise off the handle cover with a flat blade screwdriver. Then remove the 2 screws which fasten the handle to the jug.
Next, remove the centre screw from the base of the jug.
Check the heating element resistance with a DMM. This reads about 68 ohms which equates to a power rating of V squared / R => 240V x 240V / 68 = 847W. Actual heater rating is 700W to 900W so this looks OK.
Next, check the thermal fuse (KSD301). This reads 0.5 ohm when cold and so this looks OK too.
Now check the wiring. Here, we see what appears to be a scorch mark on the earth wire. I'm guessing here but I wonder if water got into the base and caused a short between the earth wire and one of the blue wires (which supplies power to the heater element). Maybe the insulation is not quite adequate in the presence of water or maybe there was already a break in the insulation beforehand. Even though everything is now dried out, the break in the insulation and the close proximity of the heater wire to the earth wire seems sufficient to continue to causing the contact breaker to trip.
So, if this is indeed the issue, wrap some insulating tape around the exposed earth wire and put it back together and see if it now works.
And it does!
