Indesit D41 Pump Out Problem?

The main pressure pump failed (windings burnt out) on my Indesit D41 dishwasher so I replaced it, all went well but dishwasher now appears to have a different fault. If there is no water in the dishwasher the program continues properly with the new pressure pump working ok. However, when a pump out is required nothing happens and the dishwasher stalls until it times out. If there is water in the dishwasher when you start a new program again nothing happens. The evacuation pump works ok, as can be proved by connecting direct mains power to it when it pumps out all water correctly. It seems the control board is not switching the pump on when it is needed. I have checked all wiring and connections and can't find a problem, can only think the burnt out pressure motor took the circuit board with it, any ideas?

Thanks for the reply, I did check the pressure switch, which appears to be working OK in that it clicks when the water reaches its lowest level and clicks again as soon as the water starts refilling.

I also removed it to enable me to blow down the inlet tube to check the action of the switch by using a meter, again I found that it operated OK.

Is this the correct way to check the unit or should I have carried out other tests?
