    Check your inverter water pump, open the reservoir by taking the cap off, then push on/off button twice without touching the brake. If the pump is working you should see water moment and hear the pump on, if not, then the pump is likely dead. Replace the unit, if you haven't replaced the fluid before, now would be a good time to do so.
