After I press "turn on" button heat light just flashes for a second then pump starts. Without any delay immediately after pump starts I can see all water running through 3-way solenoid valve to the drip-tray. It runs without interruption approximately 90 seconds until safety timer turns the pump off and "empty tank" light is turning on. Shut it down, turn it on and everything happens again.
