Another Update... At the end of May, I replaced the the lower control board Manufacturer Number 154750502
(behind the kick plate) and the dishwasher worked great... Until a couple of weeks ago. Now, I have the flashing lights, AGAIN. But now, instead of the drying damper light being lit, I have the Main Control Board light lit. When I get the error condition, I hold down the high temp button to reset the unit. So far, the unit will work after doing this. I turned off the breaker to clear the Main Control Board light. I want to see if the Main Control Board light stays consistent with each failure. BTW... My Electrolux OTR EI30SM55JSC microwave bit the dust this weekend! I'm really glad I spent $6500 for all of these great Electrolux appliances when I decided to replace my BUILDERS GRADE APPLIANCES that didn't look as nice, BUT SURE WORKED RELIABLY. The appliances receive minimal usage as it's only my wife and I. My Electrolux appliances can't even last three years without problems. Wonder how long it will be before the refrigerator and range start having problems? QUALITY PRODUCTS? I DON"T THINK SO!
