I self-installed a dishwasher which I am certain works correctly. I
hooked it all up and ran it. Water does not drain out of it. I took
out the dishwasher, unhooked the hose and inspected it for
obstructions; none were found. The remaining water in the dishwasher
drained out once disconnected, so there was no obstruction from the
interior of the dishwasher to the hose hookup.
Having established that there is no obstruction preventing water from
draining... what could it be? This is the 2nd dishwasher I have
attempted to install and the 1st one also had the same issue, so I
find it difficult to believe that replacing the dishwasher again would
solve the issue.
Thanks in advance for any helpful advice or suggestions you may have!
the garbage disposer was not changed out.
Was there a DW there to start with? (you say you installed one, not
'replaced' one.) If that's the case, even the older disposer will need to
have the plug knocked out of the drain flange, assuming you are draining
into the disposer.
Personally, the next time I install a new Disposer I'm also changing to a
flanged drain tube on the other sink and not draining into the disposer.
Two reasons - the better DWs do a fine job of grinding up food waste (and
besides, if it makes it up the DW drain line, it certainly isn't going to
plug the larger sink drain lines!). Second, I've had two experiences with
the flange on the disposer corroding and leaking, making it necessary to
replace the disposer. The sink drain tube with a DW flange is a hellofa lot
cheaper, and probably even a little less likely to corrode.
There was previously installed a dishwasher, I was just replacing it.
I do not know what a 'drawer' model is. This is the kind you slide in
under the counter and then adjust the feet to the proper height, I
thought all dishwashers were like that???
I am beginning to suspect that perhaps the drainage hose needs to be
situated 'just right', or maybe it is kinking as you suggested. I'll
try to check into that but it's hard to work in that space... any
suggestions how to route the hose?
Pull out the DW and test run it with the drain hose going into the
sink. If it drains fine, either the drain line is being kinked when
you push it back, or you have a blockage where the drain line connects
