Pu is short for pump. You say you checked the motor and filter, but is the motor actually running when it should? If it is, you can hear it. If not, there may be a problem where the pump is not receiving power. Armchair troubleshooting isn't the same as actually being there. Keep hunting and you will find the cause.
PU code is the drain pump/\, This code can mean a bad pump, but most often there is some kind of restriction or blockage in the drain lines from the pump to the drain. Check for clogs/restrictions and clean them out and try again.
Error 6 & 4 it means laser is not reading the disc and unforutunally you need to replace the pick up laser assy.
You can get it from pacparts.com,but I reccomend you to take to a proffessional tech because this is a "static sensitive" item.
