Question about Fisher and Paykel 23 in. DD-603SS Built-in Dishwasher

Standing water in the little kidney shaped filter and scum

I have standing water in the kidney shaped filter.  Also when I took the big wheel off the bottom to clean it there was a huge amount of gross scum in the dishwasher which can't be healthy.

    I also get standing water in the bottom drawer of my F&P dish drawers. A friend look at it and thinks it is a design flaw. Any comments from the company? Anna

    We have the same problem. I called about it and the lady said that is normal-doesn't sound normal to me. We'll probably call someone else for their opinion. Sorry my response wasn't much help.

    We also have standing water in the top drawer of our double drawer dishwasher, the bottom drawer drains with no problem.   Looking for a solution.

    Thank you for the concise solution to this problem. My questions are: My machine (a 603 approx. 4 years old) is hooked up with the "Y" going directly into the disposal. Would you advise splitting the two drains and going into the other sink drain with one, to completely separate the two drains? Also, since there is some water showing up in the top drawer when the bottom has run, should I install a new "flapper valve" after separating the two drains? Thank You

Hi, welcome to FixYa.
It is normal for there to be a small amount of water in the sump area where the filter sits. As for the scum under the large filter plate- You need to periodically take it out and rinse it off and keep it clean that's normal machine maintenance.
To get the best washing results on these machines, use only POWDERED detergent, do not use liquids, and also do not use tablets or packets, as the machine is not designed for them.

If you are finding one drawer seems to get murky water in it after running the other drawer, this is called "cross draining" and it happens when the machine is not properly installed. You may have a slew of technicians come in and all of them tell you there is nothing wrong. The fact is, these are in effect 2 dishwashers sharing a single cabinet. There are 2 seperate pumps and two separate drain hoses. Often they are connected to a single "air gap" with a Y-connector. The preferred way to install them is either with a standpipe or a "dual air gap". When these machines are properly installed, they are awesome and customers love them. When tye are not installed correctly Fisher Paykel gets a bad rap and it's not fair. I personally have corrected somany faulty installaions I can;t count them all. And when I follow up with a call to the customer afterwards to check on them, they will say things like "Since you were here, it's almost like we have a totally different/new dishwasher!"
