After washing an engine it is common for water to cause some problems. Most of the time the water will end up being forced out and the noise will go away. In some cases though the water will damage the bearings or electrical connections at things like the compressor. I would check the connection at the compressor first and clear any water from there. If it is fine then the water probably caused the clutch bearing to fail, which means that the compressor needs to be replaced.
