F02 error then suds error

I have done all the suggested solutions. I checked the hose from the tub to the inlet of the pump, nothing found. I took off the outlet hose to the top of the washer, nothing found. Nothing found in the pump filter. I then replace the pump assembly, with no luck. I am still getting and F02 error and then a suds error. When I first replaced the pump it completed a cycle but not since. Is there anything else I can check. Could it be between the stainless steel tub and the outer plastic tub?
