E4 error light comes on, dishwasher won't run, this apparently means water is on a sensor, have removed water from collection tray in bottom, tilted machine backward to dry out sensor, left for 24 hours, machine still won't run. Currently a very small new counter top but a useless dishwasher.

The problem is related to the floater assembly inside the dishwasher. It is filling up with gunk and stop working properly. I found out the hard way after a good spill. The solution is easy but takes a bit of time.
1. Unplug the power and water hoses.Unscrew the main cover ( both sides , pry off plastic caps first) back, and open door to remove the screws form the left and top attached to the main cover.
2. Remove the cover completely by lifting and slightly bending the bottom to unlatch.
3. On the right side, you can see the floater assembly. Remove the single screw on the lever and turn the lever 90 degrees to remove from the piston. Pry out the reservoir cover by pressing on the two latches(one is glued on, remove the glue).
4. You will see a very dirty mechanism which have to be cleaned up totally with sponges and paper towels. If possible ,you can try to insert a flexible wire inside the rubber hose at the bottom to ensure nothing is blocking it.
5. Replace the reservoir cover with its piston and re-install the lever.
6. At this stage, before installing the big cover, you can connect the hoses and power cord and try with setting P5 to start a small run. You should see the lever rising during water filling, when the spinner start turning, water filling stops for a moment then starts again for a brief period. This is a good check of the health of the float assembly when you run your washer. There should be a brief period of stop and start of water fill like you had when your machine was brand new.
7. Re-install the cover. ( the darker colored screws go in the front (behind door). Put back plastic caps . Reconnect power and water hoses.
8. Repeat from time to time when you don't hear the start and stop water fill.

I got the same error and took all the water out of the heating element collecting tray, cleaned all food particles and mildew (yuck) from the sensor and all the cavities in the tray. The machine is back up and running.

When the E4 error came on, the machine got overfilled and spilled water all over the counter. Had to bail all the water out manually and then clean.

These machines definitely require some hands on maintenance and repair once in a while. It's my second one and having to reseal the look through window with aquarium glue after a few months is a routine.

I have a LOFRA dishwasher LOD6001/LOD60002W showing an E4 error. It started OVERFLOWING so I opened the door to turn it off. Now it will not restart.

"E4" means Error and from 1 to 5 means malfunction in water valve / sensor. E4 means defective water level sensor.

This is the Water tap closed. What that means is that the flow meter is not recording water entering the dishwasher, this can be a water tap turned off (suprisingly more common than you'd think, after new flooring or decorating has taken place),water hose kinked or blocked, the dishwasher water soleniod valve defective.

I have to replace the Thermistor / Turbidity Module on my Electrolux EIDW6305 dishwasher. (Error Code 2). I have ordered the part. Would appreciate any guidance you have on the procedure and a diagram of...

Hi Art.

Here the removal procedure from service manual:

The turbidity sensor-thermistor is located in the front portion of the water collection section of the
sump. This sensor is used by the control to determine the turbidity of the water, then adjust the cycle length as needed, and also to determine water temperature in the dishwasher. An o-ring
seals the sensor from leaking water into the base tray. The thermistor is wired to the electronic control and can be checked at the control for resistance. The thermistor is checked by reading its resistance at room temperature; this will be 10K ohms, if it is checked after a fill, the reading will very depending on water temperature.

To remove the turbidity sensor/ thermistor:
1. Pull unit from its installation position. Lay unit on its back.
2. Remove the base tray.
3. Push back the retaining clip and pull electrical connection from turbidity sensor/ thermistor.(See Figure 5-36)
4. Using a 20 Torx bit, extract the two screws securing the turbidity sensor/ thermistor to th bottom of the sump. Pull sensor from unit.



To remove the base tray:

1 . Tilt unit back to access the screws along the edge of the unit base. If blocking materials are not available, the unit may be set on its back.
2. Using a phillips head screwdriver, extract the two screws securing the base tray to the unit frame.
3. Tilt the front of the base tray away from the unit then push backwards to release the tabs from the locating slots in the rear of the unit.
4.Remove base tray for unit.

Here the picture of the Thermistor/Turbidity Module:

The F2 error means the tray underneath the unit has filled with water. You will need to pull out the dishwasher (remove 2 screws at top left/right when door open that prevent tilting). Unplug and pull out dishwasher. Remove 4 screws on bottom rear panel and you will see tray underneath. Sponge out water and F2 error will reset.
However, you should not get water in this tray. There may be a faulty valve, pump or leaking pipe. Run diagnostic mode (described in user manual) to see if leak occurs during filling, draining or circulating.

I have a Candy dishwasher. Door is open switch on sounds like something (possibly pump) is running and error E4 shown on diaplay. Any ideas please?

Overflow tray (bottom dishwasher). Tilt your dishwasher, pour water and see the reason for the overflow. I blew off the top hose from the pump.

Getting an E4 error message on portable dishwasher - Kenmore 18" ,mg DDW1805W.

E4 means the overflow sensor has activated.
Under the washer is a pan - with a sensor. If it gets any sort of water - it activates.
You can remedy this issue by pulling ut the dishwasher, and tilting it up to about a 45 degree angle to empty the catch pan.
This should solve your problem.

Error code e4

This might be a re-badged generic dishwasher - on my Baumatic E4 error caused by floatswitch in bottom catch tray. Some (supposedly small amount) water collects here and should evaporate naturally. If it accumulates, float rises and stops machine.

TURN OFF THE POWER

try to find a way into the machine base catch-tray to sponge it out - on the Baumatic there are two large black plastic plugs on the front of the machine base that can be forcibly flipped out.

failing that, take machine out and tip it up to get rid of water

Error mesage E4

E4 commonly means an overflow detected in the bottom over flow tray - try removing the kick board from the front of the machine - you should see 2 plastic black panels about 4 inches wide each, using a flat edged screwdriver pop the panels off and you will see the mechanics of the machine - the base is classed as the over flow tray - when water fills this tray a polystyrene float is pushed up and an E4 error code is detected - tilt the dishwasher back and allow the machine to dry out before trying it again - this should work unless the water seal around the filter basket is broken - in this case an engineer should be called to replace this part. Hope this Helps.
Thanks
Donna
