Smeg Dishwasher Fault, Please Help

[ardouisur]

Hi All,

I have a SMEG DF410BA dishwasher which has recently developed a fault.
It will not run any programs. Normally the first thing it does in any program is to start the drain pump, but it doesn’t even do this.
I have tried the reset thing of pressing the program button 4 times, and that did allow me to run a program once(which completed with no problems) but the next day problem returned despite trying to reset it many times.
There are no error codes shown (in that when an error code shows all 5 program lights are suppose to be lit) but the prewash does flash, no matter which program you are in.
I have checked the base and there is no water. When you manually lift up the float on the micro switch it does pump out water correctly.
I have taken the PCB out and there are no obviously burnt out components and the inlet valve seems ok (electrically anyway). The only thing I can see is that there is some residue in the base from where it must have flooded in the past.
Any advise would be greatly appreciated.

Many Thanks

After a further look, the what i assume is a solinoid located next to the softener is badly corroded and the mulimeter shows infnite reistance.

Does anybody know what this part is called, and if this would cause the problems im getting?

Smeg isn't really my thing but....there isn't an error code where all 5 LEDs are lit or flashing.
Most error codes are a combination of one (or two) flashing LEDs + one or more permanently lit LEDs.
Go here http://www.smeg-service.co.uk/support/index.php?a=1#1 click "dishwashers" then type "error codes" in the search bar on the new page.
The valve you refer to is a regeneration valve, its resistance should be around 2kohm (2000 ohms).

Well got the valve out and its definatly no good, its all rusted inside. Will order a new one and see if it fixes the problem
