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.
I had a similar problem with a washing machine, until I replumbed my waste pipes. My Washing Machine waste pipe was attached to the down pipe just under the sink bowl. I found that the U bend trap was too high and the water level in the U-bend was at the same level as the Washing machine waste pipe was attached. So we has syphoning back into the washing machine. I moved the U bend trap down by 3 inches 7 cm, so now the water leaves the washing machine falls the 3 inches to the water level of the U bend. We now have no more syphoning back into the washing machine.
The plumbing code in your area will specify where you can or can't go with the outlet line. You wouldn't want to attach it to a line where any waste from another source would pass the dishwasher connection line, because the waste could flow back into the dishwasher. That's why you normally route it to the sink or garbage disposal (no concerns about waste from another source getting into the dishwasher line).
There are several possibilities as to why water isn't draining from your washer:
1. Blocked drain filter The filter is usually at the bottom of the wash compartment. You didn't state which model of dishwasher you have, so please refer to your user manual for instructions for cleaning your filter. If you don't have a manual, please post back here with your dishwasher brand and model number for information on cleaning your filter and where to download a manual if one is available.
2. Blocked/kinked waste hose Check the waste outflow hose at the back of the washer for any kinks or other damage. Also remove the hose where it attaches to your sink (or waste outlet) and check for any blockages both in the end of the hose and at the sink attachment. If there is a lot of dirt in the hose, it may be blocked somewhere further back.
3. Blocked waste disposal / sink trap / waste outflow Make sure your sink is draining efficiently. Clean as necessary
4. Faulty waste pump If all of the above check out, you may have a faulty pump. Please post back for further advice regarding this after completing the above checks.
You will have 2 pipes and a flex, Or 1 pipe 1 flex and a connection for a inlet pipe. Connect the gray, larger pipe to the waste out let(drop in a stack or connect to a "spiggot", then connect the smaller pipe to the water inlet, you can usually connect to the washing machines inlet using a "y" piece, remembering to shut off the water before disconnecting. Then plug in the flex and away you go.(remembering to turn the water back on and a quick check for any leaks)
If there is a kitchen sink nearby you should be able to get a plastic waste pipe adaptor from a hardware store that simply screws in below the sink plug hole and joins to the U-bend pipework. It will have a short stub pipe on it for attaching the dishwasher drain pipe.
Hope this helps. D.
ok. our machine has done this for 6 months or so, it was ok for the 1st 6 months. i have checked and cleaned and unblocked and gone bloody crazy. today i found the fault and fixed quickly.
the installer stuffed up. the waster water hose must head up and be fixed just under your bench top, then come down hill to your exit/spiggot/drain attachment.
ours was just lying more or less at floor level coming up to the spiggot. so whenever the waste water pump switched off, water would run back into the machine, hence the OE error, and also dirty water with food would then get chucked around it what should have been a clean rinse.
a diagram of the waste water house and how it should be done is in the manual.
