Washing Machine Placement - Concern or not?

[Jim Chavez]

I have minimal space along the wall where my electric forced air furnace, electric water tank & the wet wall where the washer & dryer is plumbed. The water tank is about 1/2" away from the furnace and the washer/dryer & water tank are all touching. Is this a problem? Again, all electric no gas at this point. I will be replacing the water tank with a tankless gas water heater in 3 months. I just want to ensure I am not causing any issues with this setup. I've included a picture.

The only "problem" would be if the washer vibrating was amplified by contact with the dryer.
