It is the drain water from bottom drawer that is finding its way to the top drawer. This could be due to incorrect drain hose height. Check in installation manual. Alternatively you will have to buy an air gap kit and connect the two drain hoses separately to the kitchen sink.

As the drawers share a common outlet to the kitchen sink drain, it is the drain water from bottom drawer going to top drawer. Can happen if the drain hoses are not following the correct specifications for installation. An air gap kit is available to solve the problems.

There are two pieces of drain house in a double drawer FP dishwasher. The one from top drawer, the one from bottom drawer which then merge into a U adapter before hoing as a single hose into the kitchen sink.
I don't think anything can be achieved by taking the bottom drawer out. If the obstruction is in the top drawer drain hose, you will have to take that out and turn it over and disengage the hose from the bottom of the sump. Your best bet is to refer to this install guide on removing the drawers. Refer page 7 step 2.

Use reverse method to put it back in. Make sure you keep a stool nearby to hold the drawer in place and not let it fall on the floor. The cables and hoses are very tight and need care when handling.

You may want to check up if the water collects in the bottom drawer when the top drawer is in wash cycle (ie, taking water from the inlet) or during the drain cycle when it is draining water out. Leave the bottom drawer open and check while the top drawer is running.

You can do 2 things: If this problem persists it means that the "flap" that prevents the water from draining into the drawer needs to be replaced, unfortunately this is a common problem with this model if you are a frequent user. In the meantime what the tech does to empty the drawer is to run the shortest cycle which will empty drawer but you know if you need the "flap" to be replaced if the problem persists.

Hi, Make sure that the drain hoses are looped at least as high as the top washing part. With no loop the water is free to pump from one drawer to the other. I simply tied the hoses up under the sink with twist ties. That was over 2 years ago and haven't had the problem since. Good luck!

Josh, you will need to have a Tech out to look at it... F/P will not sell you parts to repair it. The F1 indicates that the flood switch has been tripped. There are many possible causes for this but probably the upper drawer link support has broken and is getting stuck between the lid and the drawer in which case you will need a new lid and link support.

yes there is. It is just inside the white hoses that drain the system. 1 per drawer. They cost about $0.50 but are a real pain to get to. This flap will go bad in about 3-5 years and maybe sooner depending on the temp of the water used.

If the bottom flap goes bad, using the top drawer will drain into the bottom drawer.

From what you describe, drain water from the top drawer is getting into the bottom drawer or waste water from the disposer is backing up into the bottom drawer.

1. Each drawer has its own drain hose. Each hose should terminate at the drain point with a 'Y' adapter.
2. Inspect the drain point (under the sink where the drain pipes are) to make sure this 'Y' adapter is present. (you should see two drain hoses from the DW). If not present, then the DW drain lines are not installed properly. (Someone took a shortcut and installed the 'Y' adapter behind the DW)
3. If terminated properly, make sure the drain hoses extend upward as they leave the drain point.

It is important the drain lines are connected properly to ensure proper drainage from the DW. Consult the installation manual for complete details.
