F1 signifies that the flood sensor in the rear of the cavity on the bottom drawer has been activated. This is caused by water leaking into the rear of the drawer. I have had the same problem with my own and also repaired a friends unit which was doing the likewise.

The water in the drawer is only the symptom of the underlying cause. You will need to be reasonably handy to undertake this operation.

Firstly you will need to remove the bottom drawer and dry out the flood sensor. Turn the unit off at the wall power outlet before you touch anything! You need to pull the drawer out fully and then activate the tabs on the left and right side at the bottom front of the drawer to move in move it out further and off the tracks.
Make sure you have some towels on the floor in front of the unit. Once you have the drawer out lay it on it's right side on top of the towels. There will be an amount of water still in the unit which will likely drain onto the towels as you do so. Now you will be able to see into the drawer cavity, preferably with a torch, and also see the flood sensor on the rear left hand side. You should also notice a fair bit of water in the bottom of the cavity. As you've made sure the power is off, you can mop up the water.
The plastic cover over the flood sensor can be gently removed by pressing down and sliding it to the right. Once the cover is off you can again mop up the excess water before using a hairdryer to fully dry the flood sensor out. Don't put the hairdryer too close to the flood sensor, just let the warm air slowly dry things out over a 10-15min period.
Once it is all dried reverse the above instructions to put the unit back together. Be sure to make certain the both the left and right tabs are engaged when you are putting the drawer back onto the rails. There should be a positive click if they are engaged properly. If not undo them fully and try again. You will notice that if either side is not engaged properly the drawer won't run in and out smoothly.

Now you can try to run each drawer. I prefer to test the top one first on a short rinse cycle. If that runs without any problems do the same of for the lower drawer. If you don't get any errors you're in business. If you do then read on for further help.

If the F1 code comes up after running either drawer then you've narrowed down which one is the problem. You will again need to remove the offending drawer and check the drainage hose. There will likely be a split at some point along the drainage hose. It's quite fiddly to remove the old one. Note: You can only get a replacement hose from an authorised parts supplier. This is due to the narrow diameter of the hose and the couple which joins the pump under the drawer. Before you throw the old one out, make sure you remove the small rubber valve. It would appear to prevent backflow into the pump and is not supplied with the replacement.
I didn't totally remove the clear housing from the motor assembly, but was able to remove it part way and gently open it enough to get the old hose out. In order to more easily complete the fit of the new hose, I would recommend carefully removing the whole unit from the wall cavity. Make sure you disconnect the inlet hose, power and drainage hoses under your sink. This allows the unit to move freely from the cavity without damaging anything. There are four securing tabs inside the bottom drawer cavity which need to be removed to do this. (All quite clear in the instruction manual).
If you are at this stage I would also recommend installing the 'retro fit link support'. It is much more practical and robust when compared to the plastic one the originally came with the unit. It has a metal rod and a mount that fits into the corner of the draw cavity. Makes much more sense than the plastic rod.

If in doubt get a service technician out. Also search up 'F1 fault' on this site for further assistance.

The unit has a leak causing floor sensor activated.
1- Unplug power cord.
2- Pull oull half way the drawer so an access from the bottom left could be obtained.
3- Use Paper towel or small towel to dry out the water on the bottom housing.
4- Wait for 48 hour so the sensor can be dry out.
Plug in the power cord. The unit will act as normal.
Your problem is solved.

However you can't operate since you know you have a leak problem. Let me know how it in progress and you decide to call service to fix it or I can guide you to fix it. Good luck.

SOURCE: Dishwasher showing wrench symbol after using dishwashing liquid

I am assuming this F1 error is coming in only one drawer and that you are able to run the second drawer as normal.

In the case of your dishwasher the F1 error occured because the foam would have overflowed over the drawer top into the base of the unit. This would have triggered a flood switch which is there to protect water damage to the dishwasher. You can either wait a few more days until the base of the dishwasher drawer unit dries up or you can dry it yourself.

To dry the base, extend the drawer as far out as possible (turn mains power off first). The use a few towels and push them on to the base. Pull the towels out and dry the base especially the centre of it with a hair dryer.

The F1 should disappear once you put power back on .

Hope this helps. You have a very helful child who sets the dishwasher up. I have to keep pushing my children to even empty it.

Kenmore_665.13129K703_dishwasher clean LED flashing code 6-1, what does this indicate


Hello Gabe,
The F6 error codes means that the control board did not detect any water entering the tub.The F1 error codes means that the water in the tub did not achive the correct temperature...so the F1 code is caused by the F6, since their is not enough water the correct temp will never be achieved.The possible reasons not enough water entered the tub is,a weak inlet valve that is not fully opening to let water flow into the dishwasher
a defective part called the flow meter that is telling the machine it's full when actually their isn't hardly any water in the tub
the filter screen inside of the water inlet valve is built up w/debris and restricting water flow through it
the water line is pinched, or restricted and no or very little water is entering the dishwasher.
Good luck i hope this helps ya to fix your dishwasher,GENE

Both drawers keep running, wont shut off F1 appears as error message with a small wrench showing


water leak into the base, wrench means call service engineer. You can remove the bottom drawer by pushing in locking clips at side of rails after you pull the drawer out and lift it off the rails. DISCONNECT from electric supply before attempting to remove the cover of the anti flood sensor on rear LHS on floor. Dry completely and assemble in reverse order. It may be a faulty lid motor or simply stacking to high that caused the leak.

Flashes F1 and a wrench symbol... water doesn't drain


Assuming you are getting the F1 error in both drawers.

This means there is water at the base of the housing under the bottom drawer.

Turn power off and take the drawer out. You will have to pull out the plastic pins on either side and get the front cover off. This will enable you to pull the drawer out from the slide bar for better access. Use towels and hair dryer to get rid of all the water. The flood switch is mounted on the power board. Use hair dryer to dry this out.

Put everthing back and turn power on.

Post a comment if this is not fixed or the F1 is only coming in one of the drawers.

Showing f1 and a wrench picture shows up


The flood switch at the base of the dishwasher (under the drawer) has triggered.

You will need to turn the power off (at mains) and extend the drawer as much out as possible. Use towels to dry the base and if possible use a hair dryer.

Turn power back on and try.
Possible causes are kink in drain hose (or crack), foaming detergent (use recommended powder).

Please rate this solution if satisfied otherwise post a comment.

F1 display flashing?


Flashing wrench means a fault code has been triggered.
F1 is the fault code when flood switch at base of dishwasher cabinet turns on.

This can occur due to several reasons when moisture gets to the base of the drawer cabinet.

You will have to turn the power off and extend the drawer out as much as possible to expose the back of the cabinet. Take towels and a hair dryer to dry the base. Once the flood switch gets dry the problem will go away.

The main thing is why did the water get there. You could have a crack in the hose or simply the detergent may have caused too much foam.
