Malfunctioning BD Washer
You have several problems going on here, first the clunking going into spin [ which is not causing any performance problem by the way ] is probably a loose cam bar hold down spring as already mentioned, tightening the bolt that holds it down will probably eliminate the noise but the washer will not work any better.
The reason the washer stops pumping out remaining water once it tries to spin is because the belt is loose and the clutch is not slipping properly so the belt starts slipping on the motor pulley and since the belt has slowed down so much the pump can not pump water at all. *
You might have a bad timer, these washers had a 2 or 4 minute pump out period, also the buzzing sound that goes away when the lid is lifted during fill raises questions, The only electrical part that goes through the lid switch is the spin solenoid on this washer. The machine could also have some shorted wiring.
* foot note The ONLY reason a belt ever fails of a BD WP washer like this is that it is loose, A tight pump etc Can Not cause the belt to burn and fail. The great majority of WP BD washers ever in use have loose belts after a good number of years of use, the washers often run fine like this for years as long as everything goes well, but finally the belt looses traction as the wig-wag tries to shift into or out of spin or agitate and the belt stops moving and the motor keeps running and burns through the belt, we have seen this somewhere around 3000 times over the years.
