Fisher Paykel Dishdrawer
10 years old. It started running of its own accord around 3 AM last night - with the power off (& we have no children!).
The only way I could stop it was by leaving the drawer open.
Closing the door with power 'off' (no display) sets it going - almost: the whirring sounds are all there but it sprays no water. (Empty cup stays empty).
Also, the automatic door lock doesn't work (this does work as it should when the power is 'on').
There is no pooling of water before (or after) a normal 'power-on' cycle.
Does it has some means of detecting water sitting in it & pumps it out? If so, it seems to be that this mechanism has started operating even when power is off.
Otherwise, its guts look fine, the under-sink hoses are where they should be & it still functions normally when power 'on'.
The issue is the 'uncommanded activation' (at 3 AM!)
(Or its been behaving like this for 10 years & we've never noticed?!)
There are no error codes displayed.
