Dishwasher not draining and hoses are clear. - Whirlpool 24 in. DU920PW Built-In Dishwasher

The F179 fault code on a Miele dishwasher usually indicates an issue with the drainage system. Here are a few steps you can take to troubleshoot and potentially resolve the issue:

1. Check the Drain Hose: Start by inspecting the drain hose for any kinks, clogs, or blockages. Ensure that the hose is properly connected and not damaged in any way. If you find any issues, clear the blockage or replace the hose if necessary.
2. Clean the Filters: Remove and clean the filters inside the dishwasher. Accumulated debris in the filters can hinder proper drainage. Rinse the filters under running water to remove any food particles or residue.
3. Check the Drain Pump: The drain pump is responsible for removing water from the dishwasher during the drain cycle. Make sure the drain pump is free of any obstructions. You can access the drain pump by removing the bottom panel of the dishwasher. If you find any debris or blockage, remove it carefully.
4. Ensure Proper Installation: Verify that the dishwasher is installed correctly, including the drainage system. Ensure that the drain hose is properly connected to the drain pipe and that there is no obstruction in the plumbing system.
5. Reset the Dishwasher: Try resetting the dishwasher by turning off the power at the circuit breaker for a few minutes. Then, turn the power back on and run a test cycle to see if the fault code clears.

Error code F6 E1 on a Dishwasher ADPU 701 WH typically indicates a problem with the water pump or drain system. It is possible that the dishwasher stopped mid-cycle because the pump is clogged or the drain is blocked.

To drain the machine, you can try the following steps:

Unplug the dishwasher: To ensure your safety, unplug the dishwasher from the power outlet before attempting any repairs.

Locate the drain hose: The drain hose is typically located at the back of the dishwasher, near the bottom.

Detach the drain hose: Use a pair of pliers to gently loosen the clamp that secures the drain hose to the dishwasher. Then, carefully remove the hose from the dishwasher.

Place the drain hose in a bucket or sink: Position the end of the drain hose in a bucket or sink to allow the water to drain out.

Check for blockages: Inspect the drain hose for any blockages or debris that may be causing the error code. Use a small brush or toothpick to remove any blockages.

Reattach the drain hose: Once you have cleared any blockages, reattach the drain hose to the dishwasher and secure it with the clamp.

Plug in the dishwasher: Once the drain hose is securely in place, you can plug the dishwasher back in and try running a cycle to see if the error code persists.

If it is connected to a disposal remove the drain hose and check for a restricted area in the hose or disposal this is common also check the drain hose for kinks be sure to elevate the hose before the drain area. If the drain hose is clear and the drain is clear then you could have a bad drain pump in the dishwasher.Most problems are a restricted drain or hose

Tia The above answer would be helpful but I’m trying to get my dishwasher to drain & this makes the dishwasher do some type of cycle & doesn’t drain at all... pls advise

Your dishwasher drains into the garbage disposal. It you tried to use a plunger to clear your clogged sink or run the disposal with to much junk in it you may have force debris into the dishwasher drain hose. With both the dishwasher and garbage disposal disconnect from power disconnect the dishwasher drain hose from the garbage disposal. This is usually about a one inch black hose. Clear out any debris in the hose and inlet nipple on the garbage disposal. If debris is compacted far down the hose it will need to be disconnected from the dishwasher end and remove to clear the blockage.

Good luck!

I would first check where the drain hose from the dishwasher connects to the drain stub under the sink. Remove the hose from under the sink and place it into a bucket. Close the dishwasher door and cancel the cycle to put the dishwasher in a drain cycle. Listen for the drain pump to activate. If water comes out of the hose check the stub where the hose connects under the sink with a screw driver to make sure the spout is clear of debris. If no water comes out of the hose, empty the dishwasher by hand using a plastic cup and when empty remove the hose at the pump under the dishwasher and check to see if there is any debris at this point. Make sure hose is clear from the dishwasher pump to the drain stub under the sink. You will need to place a towel or two on the floor as water left in the bottom of the dishwasher will come out when you remove the hoses. If still no water comes out you may have to disassemble the bump assembly. Not knowing what make and model you have I can't help you past this point.
I hope this is of some help.

The first thing to try is to clear out debris from strainer area, you may need a Philips head screw driver for this. Clear out and then attempt to put the unit through its cycle.

The second thing I would try, is unattach drain hose from drain to sink, either blow in it or use a blower side of shop vac to force air into the hose. Reset dishwasher, and try again.

Not knowing how handy you are, you can pull the dishwasher out, please turn off circuit before doing so, also make sure you have towels handy. Unattached drain hose at base of drainage pump. Clear out hose and remove debris on bottom of pump. Reattach the hose and run through cycle..

If these do not work your issue is with a bad pump.

If there is a

I had similar problem and rerouted the drain hose like papps54 said. I still had the condition and decided to pull out the drain hose completely to see if there was any debris trapped inside the hose. There was! I removed the hose from the machine completely, cleared out the debris, and let the hose soak in white vinegar overnight. In the meantime, I looked back up the drain outlet and found evidence of debris lodged in there as well. I didn't completely dismantle the dishwasher at this point but I did eventually clear it out as well as the drain filter located inside the dishwasher. After reassembling the drain hose and dishwasher, I cleaned it with baking soda for three nights and now it runs very well with no odors. Runs quieter as well.

not really, it sounds like you have done all the basics,

Since water doesn't drain out ,it could be a clogged in the drain line. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. You should remove this line and clear it form any debris in the hose or the hose connection. Be sure to reattach the hose before starting the dishwasher again. Good luck!
