We just put a dishwasher in our house for the first time, never had one before. My husband installed it. We ran it today empty to try it out, and there is standing water, almost an inch, in the bottom. Any suggestions as to why? We bought this dishwasher new from a private party who didn’t need it. We have no manual with it, but it had not been used previously. It’s a Frigidaire Gallery Ultra Quiet II. It is set up to drain into the garbage disposal and then down the drain that comes out the other side of the disposal. Any suggestions would be greatly appreciated! [email protected]
