Why are my appliances failing and the breaker tripping?
Let's start with NEC Article 220.52 (B). which requires a separate laundry circuit for the  washer only. So you will need to find a second circuit for the freezer. Next you purchased a used washer and we have no idea what type condition it is in and it has no warranty (see comments above). Now that you have probably overloaded the circuit with a bad washer, you have picked up "Hissing" in the receptacle. This means you have probably caused some damage to the receptacle or its wiring. So you need to kill the circuit and pull the receptacle from the wall and inspect it for damage and make any repairs necessary. Personally I would replace the receptacle and make sure your wiring did not overheat and damage the insulation. If the wiring is damaged you need to trim it back. If the wire is then too short you need to pigtail it and reattach it to the new receptacle.

Sorry to deliver the bad news, but having a freezer compressor and a washer motor on the same circuit can cause a shortened life for each appliance. So you really do need to correct that.

Good luck and stay safe.
