A maintenance method that discharges liquid L collected in a liquid receiver 15 of a liquid ejecting apparatus includes a first step of causing a nozzle opening face 43a of a liquid ejecting head 3 to be disposed facing the liquid receiver 15 in a non-contact state and applying an electric field between both, a second step of ejecting liquid D from a nozzle 47 to the liquid receiver 15, a third step of detecting a voltage change based on electrostatic induction at the time of ejecting the liquid D to the liquid receiver 15, a fourth step of determining a liquid level height H of the liquid L collected in the liquid receiver on the basis of a result of detection of the voltage change, and a fifth step of discharging the liquid L collected in the liquid receiver when the liquid level height H reaches a predetermined height.
