Spa draining over night

[DAR912]

Hello,

i need your help. A good amount of our spa water drains itself to the street over night. When the system is on, water goes from the pool into the spa and falls back into the pool.
Some details:
- the spa water does not drain into the pool
- there is water out in the street at the overflow line out, but it does not come from the overflow of the pool
- the filter seems to be partially empty as well ( when the system goes on the next day, you can hear the filter filling up before water goes back into the spa)
- a lot of air come up into the spa when the system turns back on

thank you for your time.
D
