The diagnosis: probably an internal short circuit.
This is what happened to my machine, and because it's out of warranty I thought I'd have a quick look at it myself. Turned out to be simple fix, so here goes...
Getting access to the wiring we need to look at is easy enough.
1. Disconnect power from outlet (obviously);
2. Use your Torx T20 to driver bit to remove 4 screws holding the rear cover, then turn the machine upside down and remove 2 small philips-head screws securing the base of the rear cover. remove the cover.
3. Gently bang the top die-cast cover from the back to try and dislodge it and move it towards the front of the machine (there are no screws holding the cover on the BES820, it is just a tight fit under some lugs). Your attempts to move the cover will be met with resistance. In the end I needed to thump it quite hard with my hand. A rubber mallet would probably be ideal, but I don't have one. Once you have pushed the cover forward by about 10mm, you should be able to lift the cover off.
4. Unscrew the earthing cable form the top cover and put the cover aside.
5. Now inspect the visible cables. Look in particular for any pair of wires that may be making contact with each other. This was what I found in my case. Two wires had been rubbing against each other, probably due to the vibration cause by the pump, and eventually had rubbed through the insulation to the point where the circuit was shorted. Smoking gun found!
6. If you find this evidence, you will need to a) add some additional insulation where the original has worn through (make sure it is heat and steam resistant, consult with your electronics store), and b) ideally, try to rearrange the cabling to keep some physical separation between the cables so it doesn't happen again.
When you are satisfied with your work, you can test it by plugging it back in and turning on at the wall. If you haven't replaced the covers yet, be aware that most of the visible wiring you see in there is running mains voltage, so keep hands clear!
Reassembly is the reverse of above. Don't forget to re-connect the earth lead to the top cover before replacing it. Good luck!

Have you ever wondered, 'how do I descale my
expresso machine?' First lets us understand what is exactly is scaling.
The build up of minerals inside the hot parts of your coffee machine or
espresso machine is commonly called lime scale. When lime scale
builds up inside the Espresso machine, it slows down the water flow,
reduces the boiler capacity and can prevent your coffee machine from
working properly. To keep your Espresso machine operational at full
order, it is important to descale it every three months. The time
intervals between descaling depend upon many factors. Quality of your
water and the amount of water running through the machine are the two
main factors that decide the frequency at which you should descale your
Espresso machine. The more you your machine, more often should you
descale it. In some cities, in conjunction with a water filter you can
use your coffee machine for a year or more without descaling at all. If
you use less water by drinking espressos you'll need to descale less
often than if you make cappuccinos.
Descaling products are widely available from stores
that sell coffeemakers and espresso machines. Be sure that the product
you buy to descale your Espresso machine is intended for this specific
use only. Before you descale your Espresso machine, always unplug it and
make sure that it is cold. Also, never immerse the appliance in water
and nor should you use abrasive cleaning products
or scouring materials on any part of your Expresso machine. In case
your Espresso machine does not come with a instruction guide or booklet,
then use a proper citric acid based descaling solution designed for
espresso machines. This should be mixed and prepared as per the
instructions on the bottle or packet. Once your Espresso machine has
been descaled properly you would not be left wondering, 'how do I
descale my expresso machine?', treat yourself to a great cup of coffee.
