Lamona Dishwasher error code and fault

bornjoyful

My Lamona 8670 stopped working completely. Nothing on start. No pump out and no washing.
I thought it was the pump as the pump is meant to come  on at the beginning of the cycle .
Engineer said it was the main board.
 i replaced the main board and  it  started to wash  fine but does not drain at all. not at beginning  when it is supposed to pump out the tiny bit left nor at end of cycle. All cycles work. to clean but none work to pump out the water.
I got a second hand pump and still nothing although it is possible this pump is a dud . will get a new pump now but do not want to spend more money.
I have tried running a test cycle and get this code IFt.
Anyone know what that means?
is it possible the plug in to the pump is the problem and not the  pump?  thanks in advance

Do you have the manual and is the fault code explained in it?

Are you doing actual fault finding with a multimeter or are you just guessing which part is faulty and throwing money at it in the hope that if you replace enough parts you fix it?

yes fault find with multimeter. Pump fine. PCB changed.Apparently the fault code just means it is in service mode which is not in the manual.
basically the machine  skips any pump out action (so the very beginning, the middle , and end! it washed great! the pump just won't come on.
Changed pump and tested old and new pump. Changed PCB .
PCB recieves 240V.
Wiring to pump all good. 
ground wore not getting warm and I assume ground part is fine and it is onmlive side but don't see any other things like a replay which might be causing it
 yet pump and also the solenoid are only getting 70v. hence that part of program not working. It simply waits the  requisite amount of time then moves to the next part of the program.

Something else is limiting the amount of volts sent to the pump and solenoid by the PCB.
No wiring diagrams to be had 
this is a lamona but all part and view are pretty much like any Beko from 5-6 years ago.
Any clues anyone?
