I have a F & P DD-603 dishwasher. Cleaned filters and drained drain pipe by disconnecting at waste disposer. Subsequently tried testing drainage but again it is not draining! Could their be an air-block? Any help would be appreciated. Thanks SK

Re: Dishwasher does not drain
Do you hear the motor running during drain cycle? If so, there is likely a blockage inside the motor (rotor) chamber and filter sump.
You will have to take the rotor out and lift the filter plate. There is a small channel between the rotor chamber and the filter sump. Take a thin but rigid wire and remove any obstacles. Mostly chicken bone fragments.
If motor is not running during drain cycle, then you are looking at a bigger problem and will require checking if the wash cycle is ever completed. If not, then the heater could be the problem. Will need technician if you are not familiar with fixing such things.
Please rate the solution if you find it ok, Otherwise post a comment and fixya.com will try to help you.

If the pump is running but noisy then that indicates a loose pump impeller (new pump I am afraid) if running (no noise) but failing to remove water, then I would be checking that drain hose is clear, or even that your machine is not syphoning water from waste disposal, a quick check would be to disconnect waste hose from waste disposal and see if it will then drain into a bucket, hope this is helpful.
Empty your food waste disposal
unit if your dishwasher's hooked up to one. If it's not empty, the old
food inside it will back water up into your machine. Check that your
sink trap isn't blocked by unscrewing it from the base of your sink if
you don't have a food waste disposal unit. Make sure your dishwasher or
any other appliances connected to it are not running when you do so.
You may have opened your
dishwasher's door mid-cycle before it's had a chance to drain. Check the
progress indicator on your machine's control panel. The structure of
this will differ depending on which Frigidaire model you're using, but
it should show the point your machine has reached in its cycle. If this
is the cause of the problem, close your dishwasher's door and let it
Inspect the drain pipe that runs
from your machine to your waste disposal unit or sink. If this is
kinked or has been squashed under another appliance or a base unit, the
waste water inside your dishwasher will be unable to escape. Check that
water can flow through your waste pipe freely.
Remove the bottom shelf from
inside your machine and take out the plate covering the filter area. If
you don't rinse your plates before you put them into your washer, food
debris could block your filter and stop water from reaching your
drainage pipe. You can unblock your filter with your fingers. Turn off
your machine's power before you attempt to do so.
F1 means that your machine has activated the flood switch. check the drain hose that is connected to the sink pipe is not blocked. remove clip holding hose to pipe, put end of hose into a bucket and turn on cycle. it should start draining straight away. if it does drain into bucket stop cycle and clean nossel of sink pipe with a small screwdriver. then refit hose and turn on cycle. if it doesnt drain into bucket please reply and i will guide you thru how to check to see if you roto motor is jammed or faulty.good luck

Dishwasher not draining properly or not draining at all issues can arise due
to different reasons. Usually, these issues are related to kinked hoses,
knocked out disposer unit (if connected with the dishwasher drain hose) &
clogged drain pump & filter.
Also note that dishwashers do not
drain completely after a finished cycle and this is normal. Dishwashers are
designed to leave some water in the unit to ensure that the heating element
doesn’t overheat. If you suddenly begin to experience a large amount of water
being retained in your dishwasher, you have a problem. Some of the most common
reasons include that the drain hose isn’t working properly, the drain pump
isn’t working correctly, or possibly there is a plumbing problem in your home’s
First check whether the drain is
not clogged or blocked and the line is not kinked. Check all the hoses for
blockages & also clean the air gap. Has the disposer been replaced
recently? If so, chances are the knockout is still in place. Simply remove the
drain hose from the disposer, and knock out the plug. If the disposer has not
been replaced, try removing the drain hose from the disposer and use a wet-dry
vacuum (prepared for water, of course) to **** any water (and hopefully anything
else) from the drain line. Then reconnect the hose, and test the unit. If you
have checked the air gap and the drain hose and can’t locate the problem, then
it is an issue with the drain pump of the dishwasher.

It sounds like a plugged discharge line, close to the disposer. With the power off to the disposer and the dishwasher, remove the dishwasher drain line ate the disposer drain. Careful, there will be water there, most likely, so have a pan or buchet to catch the water. Pass a wire back up into the drain line from the dishwasher as far as you can towards the high point of the drain line. Remove the wire and pass it into the disposer (sink) drain, making sure that the piping is unplugged. Reassemble and try.
I've had this problem a couple of times with my dishwasher. In both cases, the cause was a shard of broken glass that had managed to get past the filters and jam itself underneath the impellor. Hard to see, but easy to fix. First ladle out the water.
Pull off the lower rotor arm, unscrew the filter and take out the filter bowl, tray and cylindrical filter. Get as much water as you can out of the filter cavity.
Then, using a Torx-20 driver, remove the screw holding the impellor cover and lift the cover off. (this is the small bit of plastic at the left end of the filter cavity.) Check whether the impellor can rotate freely by spinning it with your finger several times - if it jams or grinds, then there's probably something jammed under it. (It may seem to be fine at first, so do check thoroughly, as any debris can move around with the water flow and only jam occasionally) You may have to use a cocktail stick or similar to poke out anything that's stuck underneath.
Glass is a particular problem, since it's almost impossible to see when there's any water around (it's easy to cut yourself too!)
Anyway, that's worked twice for me now - and I didn't have to even move the machine out of its cupboard to fix it.
Hope that helps.
