Introduction
The less than 4 year old, hardly used, soup-maker was brought into a repair cafe as it was completely dead when plugged into the mains socket. Perhaps this fault is common, judging by reviews and items for sale on ebay as 'not working/parts only'
The fault was found to be due to poor contacts between the lid and the jug, (as found doing continuity testing with a multimeter) .The solution was to spray the male connector with electrical contact cleaner, then join the lid to the jug about twenty times or more to clean the mating surfaces.
I suspect some soup (corrosive with salt) and/or condensation had fallen down or was pushed down into the connector on the jug side and dried to give a non-conducting barrier. This is a bit of a fundamental design fault which is not highlighted in the instructions other than 'do not immerse in liquid'.
It is not possible to inspect the socket side of the connector as it is a sealed unit.
This repair should work on similar makes and models e.g. Morphy-Richards soup maker.
it's recommended to dry the soup maker thoroughly after use and leaving the lid off for a bit to stop this fault occurring again.

With the mains disconnected, remove the lid and invert it and place on jug as shown. (This keeps the lid upright and steady)
-
Note that there are 4 pins on the lid section and 4 holes in the jug section (yellow arrows)
-
Spray some electrical contact cleaner on the 4 pins and replace the lid section the right way up on the jug about 20 times, so that that the electrical contacts rub against each other numerous times to remove any non-conducting residue.
-
Wipe away any liquid and allow to dry (for an hour or so?)
-
Hopefully the soup maker will now come on when plugged into the mains. The buzzer should sound and the LED lights should flash awaiting the mode button to be pressed.
-
If the soup maker does not turn on, disconnect from mains and repeat the cleaning process with the contact cleaner.
-
-
-
If cleaning the contacts several times in the previous step did not work, remove the 13 screws to split the lid in two as shown in the image and replace the lid (the right way up with mains turn off!)
-
With a multimeter, measure the resistance between the two terminals marked with green arrows. It should be about 60ohms.
-
If the resistance is much higher or open circuit, then either the contacts need more cleaning, or the thermal fuse/ heating element has failed (not covered by this simple guide)
-
Note: if the thermal fuse or element has failed, the soup maker will not work at all even in the blender mode which does not require the heater.
-
This is a quick technique to get a soup maker working again with no special diy skills . All carried out safely with the mains power disconnected. If this doesn't work, then some diy/ disassembly skills are required eg changing a thermal fuse (not covered here).
