Introduction
The teasmade was only a few years old and although it heated the water, as required by the clock, the hot water did not flow into the tea pot.
Access to the inner workings was gained by removing the numerous anti-tamper triangular head screws in the base. Inspection showed that the boiler's temperature sensor was not properly located. After this had been moved, all worked well.

shows general view of the Swan Teasmade. The teapot handle can just be seen on right. The boiler filler cap is on top left. It's necessary to remove the base cover to gain access to the workings.

Note that the temperature sensor (arrowed) has not been assembled correctly. It is not in the centre of the boss and overhangs. Undo the nut slightly to slacken the spring bar and slide the temperature sensor into the centre. re tighten the nut. (The other end of the bar holds a thermal fuse in place)

Note the temperature sensor has now been slid into the centre. (I also added a little more thermal paste but that may not be necessary).
-
With the boiler's temperature sensor in its designed position, the microprocessor can better control the system, so that it turns off the boiler when all the water has flowed out of the boiler into the teapot.
-
I'm guessing that, when the temperature sensor was assembled incorrectly, unexpected temperatures caused the boiler to turn off for safety reasons

To reassemble your device, follow these instructions in reverse order.
