Question about Dishwashers
Hi, I have a Delonghi dishwasher - ST9AU and I'm getting E1 on the screen. The dishwasher will not finish it's cycle and it has just started to leak water. Can you please tell me what this code means and how I can fix it? Thanks, Regards, Steve

it should have water just below filter tray, if it does not actually empty then you have a blockage ,remove left side panel to gain access to drain pipe and side chamber. Regards Engineer

EI is an error to do with your drain. Check your drain hook up. You should have a loop out side the unit, it should be a minimum 40in in height, or put in a air break. What I believe is happening is your unit is siphoning out. Fix this and you will be able to stop washing the dishes by hand.

Sounds like you've diagnosed the solution on your own.. Most of the inlet valves are spring loaded so that if power is removed or disabled.. it defaults to a closed state and doesn't allow water int the wash basin. To open, they need to be energized by the control system so you may have one of two issues.. a faulty inlet valve that doesn't spring closed when it is not energized or a controller that is comanding that valve to open ( less likely of the two) For a quick test.. make sure the DW is dry inside and open the door. wait and watch for water to enter the basin.. If it does begin to fill up.. your inlet valve could be the root of your problem.. It is also possible that you are back-siphoning waste water in from the drain system. If the water looks dirty then that is more than likely the problem so you may have a clogged pump, kinked drain hose or your drain system itself is not draining as fast as the DW pump forces the water out.
You should routinely clean the pump filter so that the pump can remove all the wash water without having to draw it thru food debris caught in the filter.. Hope someof these ideas will help you solve your problem..

Please check at both ends of the drain hose and confirm that you do nit have a leak. Also, please confirm that water is not leaking directly under the dishwasher.
If you are certain that you do not have a real leak, check the impeller (under the mesh filter in the sump area beneath the lower dish rack) is not damaged and is firmly in place.
The E1 error code is a Leakage Error, detected by the motor spinning faster than it should if the unit is filled with water.
Please report back with what you find. Good Luck!
