Zanussi ZWX 1605 W

[EP49]

Hello

Picked up this machine today and got it home and connected. Turned it on and orange power light came on, it beeped and I could see leds for other functions come on. 

Then I left it for a moment to get some cleaner and when I came back the orange power led was still on but no other lights were on.  Have tried turning off and on again. Tried pressing start/reset buttons etc and nothing. No flashing lights

So was wondering if it is some kind of safety shut off ? Or will I need to get an engineer out?  Have left unplugged and then tried again same....

Found copy of manual online but doesn't cover my issue!

Any ideas before I have to call out a repair person...? Thanks in advance

Got this sorted yet? First thing I would advise as to doublecheck the door is closed properly and firmly. Other than that it may have a fault. If the display was powering down to save energy powered expect it to come straight back on after pressing any key.
