My xc356 has simply stopped working. Nothing happens when I turn it on.

Could be the door interlock or simply there is no water entering the machine. Check water supply and also the vales inside the machine . the solenoids should buzz nd hum a little if they are energised but could still be blocked ???

it is possible that the bluetooth connection being cut midcall to have froze the bluetooth headsed, one thing you should try is to power it up in connection mode and see if it works, there are different combinations of buttons, assuming you have power and volume buttons to do a hard reset to it... otherwise i think you should take it where you bought it and ask for solution even if warranty period is over because it simply isn't normal what happened.

best of wishes and hope i helped. good luck

It could be that the fan / fan motor has seized or jammed. Have a look through the vents and see if you can spin the fan. If not, you will need to strip the machine. Try lubricating the bushes / bearings. Often on these type of units, the vapours dry out the bushes and then they get tight and jam the fan.

You may need a new fan motor. If you can get to this
motor, with the power disconnected, see if the blade
is free to move. Do you hear any sound coming from
this unit?

Reset it at the household circuit breaker for about 10-15 minutes, and retry.

Ok so your dishwasher won't do anything... it justs sits there and "Hums" you can't make it respond to any controls, and the ONLY way to Stop it. is to unplug the unit, replugging back in it simply "Hums" again and will do nothing.
Now this happens because, the STOP Button, is pressed and the "Door Opened", during the Wash Cycle. This should NOT be done. You shouldNEVER TURN IT OFF MID-CYCLE. you should instead, Simply, pull on the handle, to Open the door, the system will take care of everything, after, you close it,and pick up where it left off. The turning OFF, makes the machine "Think" that a New Cycle, is going to be done, before the old one is finished, and resets itself to do it all again. But it still has water, that's not meant to be there so it must dump it out.
Now, the FIX. Take the Dishwasher, out, and tip over on it's side, tip to about a 45' angle. Water will come out from underneath, this is from a small "Overflow" reservoir. this reservoir has an "Anti-Flood" switch. The removing of this water will "Reset" this Switch, and allow the dishwasher to work again.
So what happens, is this, when the STOP button is pressed Mid-Cycle, the machine must "Dump" whatever water is still in the machine, into the "Overflow Reservoir". This water then causes the Anti-flood switch to jam, and this stops the machine, until it is reset,by the above method.

try reseting it there should be a reset button somewhere on the device

First check the fuse, then the flasher. If it still doesn’t work you will check the relay. Finely and more difficult is the turn signal switch. This involves removing the steering wheel.

WITH THIS PRINTER ITS CHEAPER TO REPLACE THAN REPAIR SOUNDS LIKE THE LED OR ILLUMINATIN LAMP IS BLOWN
