dishwasher is only six months old…I highly doubt it is the pump…difficult to remove and reinstall…does not drain into disposal but does connect with my sink drain…has worked perfeclty until now. Would Drano damage my dishwasher? What about Lye?
If its asimple blocked waste pipe, disconnect the waste from the trap or garabage unit, take a DEEP breath, and blow HARD back down the pipe. This, quite often will clear it. Then you are able to remove any crap from inside the machine
