"I want (out) as quickly as possible," Erat told Czech paper iDNES.cz.
Erat voiced his frustration over his limited playing time. The native of Trebic, Czech Republic, has averaged 13 minutes and seven seconds of ice time per game, the lowest among the team's veteran players.
"I hope it gets resolved," Erat said. "I believe I will not stay here too long and will get an opportunity on another team."
Erat hinted that he has spoken with Capitals GM George McPhee about his situation and that the team is looking to facilitate a trade.
"Yes, we talked about how to resolve this," Erat said. "Hopefully something will happen and I'll be out of here as quickly as possible."
In 23 games with the Capitals this season, Erat has registered six assists and eight penalty minutes.
Erat, who owns a no-movement clause and could have a say in his next destination, has one-year left on his contract beyond this season with a salary cap hit of $4.5 million.

Capitals GM George McPhee has since acknowledged Erat's trade request, which was initially made at the beginning of the season.
McPhee told the Washington Post he would not consider eating up any of Erat's salary in a trade.
