from what i have found, i20 means drain pump is not working correctly, I have found in mine that the impeller is not fixed firmly to the shaft so the shaft is spinning, but the impeller is not pushing the water. so it times out as the water is not being pumped out. I have seen a replacement pump listed at $55 or so here "http://www.albury.net.au/~allfix/catalogs/dishwash.htm" 0214400030 Dishlex DX302SJ Drain Pump $55.83
