If the lid is open and closed and the icon will stay Red and not engage it would be a good to try another magnet placed on the Lid Sensor itself near where the lid closes to see if at any point it does change from Red. If the Water icon is still Red it could be a faulty water sensor or wiring to the controller board or the control board itself and if you are having a issue here we can troubleshoot further with a support ticket Next, open the right side panel of the machine and locate the "WATER" wiring and reseat this connection which is near the bottom of the green control board. You can remove the water sensor by unscrewing the 3 screws and clean the inside with a Q-tip and once it is reassembled and installed correctly with the embossed arrow on the water sensor facing to the right this would rule out being a dirty water sensor. It is possible the water sensor itself may be dirty/clogged so it wouldn't be spinning at the correct flow rate to trigger it to be active. If the water lines are correctly connected be sure your Water Pump or Coolbox is turned on and flowing water which you can typically apply some pressure to the water lines and feel water flowing within them. If the water icon is Red you will want to check your Water In / Water Out tubes to ensure it is correctly connected to your Hobby Water Pump or Coolbox unit, this would be Water "Out" from Pump to Water "In" to Machine and then Water "Out" from machine to Water "In" on your Coolbox or into a bucket if you are using a Water Pump. In most cases one of these icons would be red which would not allow the laser to fire.

If you are running a job and it doesn't appear anything is marking on your material and you can see the laser tube not firing we have a few items to troubleshoot for this.
