A blaze at Mayday Hills caused extensive damage to the building, which had undergone a renovation.
Thick smoke could be seen pouring from the roof.
CFA duty officer Brett Myers said the damage had been confined to a kitchen.
"No-one was present at the time of the fire," he said.
"The cause of the fire has been determined to be a dishwasher.
"Firefighters did use thermal imaging cameras to investigate the roof area of the structure, but were comfortable the fire hadn't spread extensively to that area."
Mr Myers estimated the blaze, which about 15 firefighters attended, caused between $50,000 and $100,000 in damage.
