Washer won't drain and is making a grinding sound

That grinding noise could be something caught in your drain pump.  The fact that it doesn't drain could be that something has lodged in the pump and either stopped the impeller from turning, or has ruined the pump.  This is actually a common problem with the small front load washers.  If you remove the lower panel just under the door the drain pump will located in the front on the right hand side.  You will need to remove the inlet hose from the pump.  This is the hose that runs from the tub to the pump.  Unplug the washer first, and drain any residual water from the tub by using a wet/dry shop vac and attaching it to the drain hose at the standpipe.  If you can manage to pull the water from the washer in this manner, you will avoid a huge mess later.  There's roughly 7 gallons of water in the tub when it is full.  I don't think you would want this much water gushing all over your floor.  With the drain line removed inspect the impeller of the pump for obstructions.  The most common culprit is coins, drill bits, screws and nails.  Even tooth picks and cotton swabs can stop the drain pump if they become lodged.  If you find the pump clogged and manage to clear it, you still may have to replace, however.  Just keep that in mind.  The pumps are usually pretty durable, but depending on how long it's been in it's current condition, it may have ruined the pump motor and/or impeller.  I hope you find this information helpful.  Good luck to you and post back with comments if you have any further questions.
