Have a husky power washer that has little pressure. Tried different wands so that's not it.

The wand is never the pressure problem that way. Its either a pump seal or low inlet from water source to machine.

Did you check the filter screen no#11 on the parts drawing

Hears the operating manual for your machine in case you lost yours.
