There does not seem to be much information in the manual about this. My dishwasher is not draining.. just starting happening. I am wondering how do I take it appart to see if I can drain it, or unclog it. I see there is a button that would appear to disconnect something but not working when I press it. Also, I notice in the manual that there is a 2-5 year warranty that mentions the drain motor being covered for defects.. wondering how this gets determined and do they stand by this?
