Hola Lewis!

This is such an easy repair, you'll be shocked and surprised! The reason this is happening is that the computer or timer has detected a "flood" condition and has permanently energized the drain pump to clear the "flood".

What you'll need to fix it...
1.) Shop-Vac (for vacuuming water) with a crevice tool (like one of these)
2.) T20 Torx bit with a driver. Torx sizing here. (You can get a set at Home Depot or Lowes)

All you gotta do now is get down on the floor and remove the kick panel. Then remove the screws holding the water valve and lift it up out of its' plastic holding. Now your shop-vac w/ crevice tool can be used. Stick the crevice tool in there (about 10") and vacuum up all the water that's been trapped in the basin. (you may need a flashlight to see what's going on back in there...) After the water is gone, your DW will work fine.

Here's how it works... About 10" behind the inlet valve is a "float" made of styrofoam. When water gets into the basin, the float rises and eventually trips a "flood condition" switch. This switch shuts the unit down and will only allow the drain pump to operate. So what you want to do is get the water out of the basin.

There may be a reason for the basin flooding, though. Suds (caused by too much (or the wrong) detergent), an actual water leak from the valve, etc... So after you get the water out of there and the unit is working again, you may want to monitor it (like, only run it when someone is home) for a while just to make sure that a real flood does not occur.

Hope this helps.

SOURCE: ASKO 1555 dishwasher won't run.

Hello,

Welcome to FixYa.

Based on your description " The anti flood device motor won\'t stop running but we\'ve removed all the water " It is likely nothing very serious.

The flashing lights are directly related with overfill scenarios for Asko dishwashers of this era...DW95.5, meaning the control is indicating an overfill has been detected. Whether the unit has actually overfilled or not remains to be seen.

In the event it has, the outlet/drain pump motor is automatically turned on via either the pressure switch or a float in the base if sensing an overfill and removing water from inside the dishwasher will do nothing to resolve this error, but you can...

**before proceeding turn the dishwasher power off via the home breaker panel, or unplug it from the wall if that is possible...most are hard wired to the home electrical...safety first**

The first thing to do is remove the toe panel/kick plate and inspect the base for water. If water is present, with the aid of a sponge, towels, or a wet-dry shop vacuum, absorb the water from the base.

If the unit works fine after resetting the power/breaker it can likely be chalked up to a drain back-up or obstruction in the drain hose or pump.

If not, there are a couple of other possibilities that I'd focus on.

**again insure power to the unit is off**

The first is the float and subsequently, float switch. If you've removed the service panel at the bottom, or toe plate, you need to locate the float and it's switch. It will be located directly behind where your main electrical junction is...

i.e.

macmarkus_4.jpg
Once you've located the float behind the main connection plate, you should see something like this image below,

i.e.


macmarkus_6.jpg
With the aid of a long screwdriver or if you can reach it, move the float up and down and listen closely for the switch to "click", indicating it is indeed functioning.

Restore power again, and see if this resolves the issue, if not try this next...

The pressure switch too can cause all the lights to flash. It is the component which controls the normal fill level and the overfill detection...pre float activation. The float is primarily the last ditch safety to notify the user in the event of a overflow, back-flow, or leak underneath the unit to service or call for service to the unit.

It too is located under the machine and is mounted to the sump well assembly as shown, the large arrow indicates the switch while the small is the hose.

i.e.

macmarkus_7.jpg
The issue is possibly just the hose going to the switch is clogged with debris such as dirt, detergent buildup etc and will be remedied by blowing it out.

The best way to do this is to remove this hose at the switch in the location indicated above, be very careful as to not break the hose off with the part of the switch inside, they can be delicate.

I typically work it loose with a tiny screw driver gently working it away from the switch. Once removed, pour a small amount of hot water, white vinegar or "CLR" through the sump from within the tub...or you can try blowing it through with "lung power".

The other end of the hose is located at the back of the sump well and is quite vulnerable to blockages over time due to detergents, dirt, and such.

This is the location...do not break this or you will need to replace the entire sump well...no fun.

Large arrow is pointing back to pressure switch, small indicates connection to sump well, sorry for the poor quality...it's hard to get in there with a camera phone, ha ha !

i.e.


macmarkus_8.jpg
That's almost the extent of the possible causes of this error. Of course it could be the pressure switch has failed, the float switch has failed or ultimately the control has failed, but not likely.

This attachment below is also a retrofit tip from Asko regarding changes made to the pressure switch on the early DW95 series machines. you can identify if yours is this type by looking for the small white suppressor in the pressure switch...if yours doesn't have it you may want to change it while your at this repair.

Available at "repairclinic.com" for about $45USD.

Hope this helps move you forward, or even better resolves the issue altogether. Let me know of course, I will help you move further if necessary.

Good luck.

Regards,

Macmarkus :)

How to fix neff dishwasher


Sounds like you have water in the base of the appliance caused by a leak, which in turn has activated the anti flooding device. OR the control module is faulty.
Remove appliance from housing and remove water from base, check for leaks.
OR
Replaced control module

Neff s5443x1GB/29 dishwasher starts and stops


The pressure chamber or hose (pressure chamber to sump) may be blocked and the microswitch is being activated because the water is not entering the tank quick enough. Isolate from electric, remove lid and left panel (looking from the front). There is a plastic chamber bottom right of left side with two microswitches, either this is blocked or the hose that runs from it to the right and along the back of the kick panel and into the sump. Clear either or both (make sure all hoses are pushed true when repositioning).

Fisher and Paykel DW920 dishwasher pump wont stop


This means the flood circuit is triggered. There is a leak in the dishwasher causing water to collect in the motor chamber. The leak is usually through the door seals or broken hose. Disconnect mains electric and water connections and pull dishwasher out from under kitchen bench. Tilt it from side to side to get the water out from under the base. Wait a little for water to dry up. Reconnect mains power and turn on to see if pump stops running. As mentioned source of leak needs to be fixed.

Dishwasher not working. Start button works ok as


Hello,

It sounds as though the Anti-flood device has kicked in,could be due to a leak under the dishwasher,it will need to be pulled out and investigated.
I would also check that there is water at the hose to the machine.

Hope this helps.

We have a neff dishwasher and the pump is draining all the time (even when the door is open) but there is no water in the dishwasher. Is there a way to stop the pump and reset the setting for the flood...


Hello,
The water which has activated the antiflood device is actually underneath the appliance it is held in the sump tray and this has to be drained before the A.F.D.will cancel.You will have to remove the dishwasher to get at the underneath but when you have got rid of the water you will still have to trace what caused it.The seal on the circulation pump could be a suspect or a pin hole in the drain hose.

Hope this helps.

Neff s5946 slimline built in dishwasher. Fills with water, clonking sound in pipe and does not register on programme, although pump working.


if you only hear the clunking sound while the dishwasher is filling then the inlet valve is bad.. i would replace it because if it fails completely you could possibly have a flood..

Bosch dishwasher


is all the water draining from the tub? if not the pressure switch will not reset and it will continue to try and clear it self...check drainage system.
2. pressure switch is jammed on..build up in the sensing chamber..common..or switch faulty...rarely
3. if water is in the bottom panel most have a flood switch which automatically operates the pump in case its over filling
