I have a Error message E4 which will not clear, have tried emptying the salt compartment, although did not manage to completly empty it ( it contained water, is this correct) checked the water inlet which appears to be ok, tried turning it off, but no change, if water is placed in the bottom of the dishwasher, on startup the pump pumps all water clear. Tried to reset it by switching it off. The manual only says that it is an overfill problem, but says it could be a number of cause`s. Do you have any suggestions???
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.
Instead of taking the appliance out of the housing to tilt it I took the two plastic plates off and put a towel in to soak up the water, it did the trick and all is working well now. Hope this helps.

Hi I'm a kenwood engineer
E4 means that the flood sensor located in the sump of the machine has got wet!
It only should get wet if the machine is leaking somewhere.
The sensor is designed to switch off the machine if triggered... To save flooding your kitchen!
Very good idea really - as most machines don't have this feature and flood the floor until the cycle is finished.
Yes you need to tilt the machine back to drain the water from the sump first.... Then look for your leak. The leak cud be on any hose or water pump... Or the seal under the filter chamber. Once leak fixed and water drained/dry
E4 should clear. Make sure machine is empty and unplugged before messing! :)
The float switch might be tripping. Pull the dishwasher out (if it's under-counter) and tilt it forward gradually to about 20 degrees. If you see a pool of water on the floor, it means that water is getting into the bottom of the dishwasher underneath the washing compartment.
This can simply be caused by a loose retaining nut on the salt compartment. Unscrew the cap from the salt compartment and you will see a large plastic nut underneath. If it's loose, tighten it - you'll need a large pair of waterpump pliers or stilson for this.
Assuming this was the problem, make sure you empty all the water from the bottom before you put it back by tilting it forwards until water stops coming out.
To stop the problem returning, DON'T over-tighten the cap on the salt compartment. Make sure it's on firmly, but if you overtighten it, it will grip the nut and loosen it the next time you remove the salt cap. If the nut is loose, water can get into the bottom of the washer.
Just flush it out by pouring plenty of water into the receptacle. You don't have to get every last trace out. Make sure to wear rubber gloves and possibly eye protection as the powder is caustic and so you need to avoid skin and eye splashes.
You could alternatively leave the salt chamber cap off and run the dishwasher empty for a couple of cycles; that will allow the powder to dissolve without any chance of you getting splashes on your skin.
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.

Try removing all dish trays and salt softner lid, check if the salt softner compartment is full of water, if so place the machine on its side and allow all the water to drain from the compartment, once this is done your machine should be good to go. This is how i resolved my problem. The salt softner is located next to the water drain filter.
there should be no salt getting into the wash cavity. if you are sure that it is leaving salty water on the items then either the salt cap is loose/damaged or the regeration system is faulty-this is an expensive fix.
