After the Alexandrian side's 1-0 league win over promoted Wadi Degla, Al-Ashri told Modern TV that he had stepped down from his role due to disagreements with the club's board.
The highly-rated tactician said Hodoud promised to double the players' bonus for league victories but didn't live up to their word after Thursday's win, which prompted him to resign.
Hodoud chairman Abdul-Hakim Mosalam criticized Al-Ashri for announcing his resignation on live television without informing the board members first.
However, both parties buried the hatchet on Sunday.
"I truly respect Hodoud's officials," he told FilGoal.com. "They asked me to return to my job and I just can turn them down.
"I owe Hodoud a lot; they helped me promote my coaching career over the past years and now I'm official back."
Al-Ashri is credited with turning around the fortunes of Hodoud, who used to be a modest team prior to his arrival in 2006.
They won the Egyptian Cup in 2009 and 2010 at the expense of ENPPI and Ahli respectively under the guidance of Al-Ashri.
Hodoud also clinched the Super Cup title last year after overcoming Cairo giants Ahli.
Last season, Al-Ashri also handed in his resignation before Hodoud talked him out of leaving.
