if there is 230v at the pump connection when you select drain then there is 2 options.pump faulty which you say has been replaced or there is a blockage somewhere.does the pump impeller rotate?.remove the filter and select drain and look in to the filter housing to see if the pump impeller is rotating.if the old pump windings where burnt out there is a good chance it has damaged the triac on the main pcb
