Hi Asif,
 
I don't believe you mentioned how long your brew process goes, but here's a 
couple of things I'd be looking into:

a) Taking the electrodes out to 4cm apart.
b) Using a larger volume brew vessel for that dimension electrodes.  I brew a 
litre or more at a time using electrodes shorter than yours {between 8cm and 
10cm depending on which of my units I use on the day}.  My electrodes are 3mm 
dia tho.
c) Remove the electrodes at regular timed intervals to wipe them clean {if you 
think they need it or not} before resubmerging them.
 
Sparklies in the water?...I've noticed that some DW I purchase {only an El 
Cheapo brand} shows some sparklies upon using laser pointer straight from the 
bottle.  I have also seen microscopic bits of 'fluff?' or fibre, or whatever 
may be in the air on the day I brew become evident in the water after a couple 
days in storage {I store in sealed containers}.  I believe these give the 
illusion of settlement due to some silver 'attaching?' to these microscopic 
bits of 'stuff?' present in the DW, or which has entered the water from the air 
during my brew process {I brew in an open top vessel}.
 
Just a few things I'd be looking at if it were me.
 
N.
