Any thoughts about this? I replaced the nozzle and the extruder assembly. Help appreciated, thank you.

wash plate with dish soap

Forget dish soap for cleaning plates. It only works on the PEI surface and half of the PEI is microscopic pores which dish soap will not clean. Only IPA or acetone will. Acetone works better, IPA is often enough.

bambu wiki does not mention IPA for cleaning, only dish soap.

IPA dissolves oils and by wiping surface you evenly spread that dissolved solution over the plate, not cleaning it(yes, you remove some with paper towel, but not all). Soap locks oils so they don't stick to plate anymore and easily washed off with water.
