For the MDJ3000AW manual ask at - they have it listed.

Re: E4 error on new conia dishwasher

Had the same problem. First you will need to tilt dishwasher back 45 degrees and tip out all excess water. A couple of towels on the floor are a good idea.

Second check that the little nozzle on the elbow under your sink where your overflow attaches is drilled out.

This fixed my problem after fussing around for a day and I was starting to disconnect everything to take it back.

Re: E4 error on new conia dishwasher

I have a Maytag MJD3000AAW dishwasher and it was showing E4 during a cycle. On checking the pressure tube from the outlet of the dishwasher to the nozzle on the u tube under the sink, I fould that the dishwasher was not draining properly as a kink have developed in the tube where it curved back to the nozzle. I slid the pressure tube into a long elbow which stopped the tube from pinching. Problem solved.

Are the dishwashers supposed to drain completely away as there is water sitting under the filters?

There is a check valve on the pump outlet where the drain hose connects to the machine. It may have something holding it open.

Hi just finished today my new kitchen, ds9800 new euro art


Don't know Euroart. However I would bet it is a Chinese manufactured product with European aspirations.

Anyhow, if the machine keeps filling up there could be a problem with either your inlet valve/solenoide. Sometimes the solenoide sticks and does not shut the water off.

Or alternatively your pressure switch or pressure hose has a problem. If the pressure hose has come loose then the pressure switch does not detect water level.

Hope this helps.

E4 fault code

Hi, when a dishwasher goes into overfill mode it usually means that the bottom tray has water in it that operates a float connected to a microswitch. Open the bottom panel and soak up all water then check to make sure the float is down completely.then restart dishwasher. Why it has overfilled is another problem. It could be a faulty pressure switch,pressure switch hose may have a hole in it, water valve may be faulty. Too much soap or wrong soap can cause too many suds and hence overfill.Also if rinse aid is spilt when filling. Or seals leaking. etc.

Sounds as though the drain is blocked partially. E4 is the overfill code. Try cleaning out the drain.

Kenwood Slimline Dishwasher KDW8ST2A

I have a Kenwood Kdw8st2a and have been constantly plagued by the E4 overfill error.

Lifting the front of the dishwasher and tilting it backwards seemed to clear the E4 error only for it to come back after the next wash.

I found eventually that the connection to the U bend under the sink was too narrow and was almost blocked hence the dishwasher was not emptying properly.

I disconnected the dishwasher waste pipe and ran the waste into a bucket for about 6 cycles and it worked fine.

Eventually drilled through the kitchen wall and fitted a lower direct waste pipe to the drain. Overkill maybe buit it hasn't done an E4 since.

Error 4 displayed on a danby ddw1806bsl dishwasher

E4 is overfilled condition.
There is a tank with an overflow sensor on the right side of the dishwasher. The tank needs to be drained of water to reset the sensor. If necessary remove the insulation on the lower front corner of the machine and drain into a cup or container by removing the black rubber plug at the bottom of the plastic tank.
Consult the manual for detailed procedure.
The error can occur from excessive foaming.
