How to wire a 70A sub panel? F216 box
 
I have a 15A circuit for the washer and another one for a pool. The panel came with a 1 1/4 ground screw and it fits through the bar to the box. I'm asking if this bar can be used for both the neutral and ground or do I need another bar.

TIA

you need another bar. grounds and neutrals must be isolated in sub panels. the neutral bar cannot be bonded to the enclosure (the ground bus must be bonded to the enclosure)

I assume the feeder to this panel is 4-wire and the proper size?

Sub panels require a seperate ground bar in addition to a neutral bar isolated from the panel....and they require a 4 wire feed. Do you meet these requirements? Is the sub panel in a seperate location / building? You may need additional grounding.

Just to clarify, a 120/240V subpanel requires a 4-wire feeder. A 120V subpanel can use a 3-wire feeder.

Considering we can't see what you are talking about, and an "F216 box" mans nothing to us, everything here is just a guess.

If this is a typical 4-wire sub-panel setup then you do NOT install a bond screw and you DO add a separate equipment grounding bar.

70A sub panel......
 
The box has two seperated busbars for the hots, neutral bar on the top right and I'll put a grd bar in. I just need 120V on each side not 240V total because I need the two circuits separated for the two 15A breakers with 14Awg out of them. Would two 14awg hots be fine to supply this SP, 20 feet from the panel in the basement, washer located in the same place and the pool is less then 150 feet (of wire) away.

Q2: off this subject, is 10awg good for 40A if the run is less then 30 feet?

Re: 70A panel
 
Line side
Lug one with 15A breaker
Lug two with 15A breaker
Could I use two #14 to supply these 2 breakers?
I just need 15A on each side.

Load side
With #14 out of the breakers to the pool and the washer.

If using 15A afci breaker do I still need to install a gfci by the pool?

Washers need a 20A circuit, and pools are typically 20A since you need a MINIMUM of a #12 INSULATED ground for pool equipment.

Where is the feed for this new panel coming from?
Size and type of breaker?
Size and type of wire feeding the new panel?

You said in an earlier post you have two 15 amp circuits. Are these existing or are you adding them?

I am suspecting by some of your previous answers that you may be in over your head.
