@GreenZombie Yes, you must have misunderstood. You must be the first (to at least report) that uses the Ore Washer and still uses the Smeltery instead of something like an Induction Furnace which only uses 1 EU/t to smelt really fast. If you can afford the power for an Ore Washer you surely should build an Induction Furnace as the power need is miniscule compared to that.
