Dedicated circuit for washer/dryer
I moved a washer/gas dryer setup from a dedicated 120v/20a circuit (#3) to another level of my house and am now on a 120v/20a circuit (#8) that serves many outlets and 2 fixtures.

I noticed lights were flickering while the washing machine was active.

I assume I should run new cable and create a dedicated circuit for the W/D.

Can someone explain if that assumption is correct and, if so, the DIY process?

Assuming you are in the USA and since you relocated your laundry the electrical code requires that at least one 20 amp branch circuit be installed for laundry receptacle (s)....and may not serve anything else. Soooo yes you need to get a 20 amp branch circuit to your laundry room and for receptacles only in that laundry room.
You need a 20 amp single pole breaker or an unused one in you breaker panel enough 12 awg wiring either NM-b (romex) or wires in conduit to go from the panel to the location of your receptacles. A single duplex receptacle would be minimum.... if you iron your clothes in that area then maybe have 2 or 3. Any basins within 6 feet and the receptacle(s) need to be gfci protected.

Do you now how to access your breaker/fuse box and bring your wiring into it to make connections for 120 volts?

I'm going to cut the drywall, add the box, run the wire to the box and might make the connection. If I don't make it, a Electrician will.

The difficult part would be the cable run. What do the Pro's do? Run inside existing conduit or, run Romex.

If run inside existing conduit, any tips on running 40' from the box to the destination with 90 degree turns along the way?

Running a romex cable if local code in your area allows this would be the easiest. Places like Chicago allow metal conduit only.

Using existing conduit with wires already installed would not work. Not knowing how many bends and the routing just wouldn't be practical.

It has been brought to my attention that this may not be that tough to do. and I may have been a little too hasty to tell you it won't work.

Can you give us more details about this 40 feet of conduit? Is it empty?
How many 90 bends, any switch, receptacle, light boxes along the way?
Inside of finished walls? What kind of conduit and its size ?
