Slamming Lenhamm, Chappell called him a 'hypocrite'.
"I don't like to be called a cheat and basically he's calling all people who don't walk a cheat, which would include himself. Cheat is not a word you should use very light-heartedly, and even if you are being light-hearted that's a word you should steer away from," Chappell told BBC Radio 5 Live.
"And even when you've got your tongue in your cheek it's pretty hypocritical for an Australian to complain about somebody not walking," he said.
In a radio interview,Lehmann earlier attacked Braod and said he was a "blatant cheating" for not walking after edging the ball during the first Ashes Test match between Australia and England Trent Bridge.
The International Cricket Council (ICC) on Thursday said Lehmann has been fined 20 percent of his match fee after pleading guilty to a charge of publicly criticising and making inappropriate comments about Broad in relation to an incident that occurred during a match.
Lehmann was found to have breached Article 2.1.7 of the ICC Code of Conduct for Players and Player Support Personnel, which relates to public criticism of, or inappropriate comment in relation to an incident occurring in an International Match or any Player, Player Support Personnel, Match official or team participating in any International Match.
"On Thursday evening, Lehmann admitted the offence and accepted the proposed sanction offered to him by Roshan Mahanama of the Emirates Elite Panel of ICC Match Referees. As such, there was no need for a formal hearing," the ICC said in a statement.
The charge related to comments made by Lehmann on the eve of the fifth and final Ashes Test during an interview on Australian radio.
The charge was laid by ICC Chief Executive David Richardson.
Richardson said: "Whilst noting the context and nature of the comments made, showing mutual respect for one's fellow professionals - including for coaches, players and match officials - is a cornerstone of how we play the game."
The range of permissible sanctions for all first Level 1 offences is a warning or reprimand and/or the imposition of a fine of up to 50 per cent of the applicable match fee.
