My no need to name dishwasher install instructions stated to plug unit into a switched undercabinet electrical outlet, we only switch on when running DW, same makers GWL 11 clothes washer manual advises unplugging after use, I presume to save electronics from power surges, spikes, and our dirty power variances, (terminology from salesperson touting benefits of Monster clean power surge suppressors.) I haven't bought one yet but following those FandP instructions no problem yet about 8 years DW and 10 years washer. Maybe those of us without panel box whole home surge suppressors should do this, but what about electric dryer, stove and wall oven, you can't easily switch off or unplug at the unit, and I don't switch off at the breaker box, MAYBE I MIGHT after paying repair bill for whichever of those burns out first. YEAH, MAYBE!
