When I moved into my house, the hippy lady that formerly lived here did a lot of DIY- some OK, some not so OK. One wonderful thing that she did was to insulate the cold water pipes and not the hot water pipes. Another was to install a leaky ice maker in the existing freezer. Gee, thanks. Anyway- we got a new efficient Frigidaire front-loading washer and dryer a year or more ago. We have had frequent error code "E70" on this appliance- like on a daily basis- which required a restart. I speculated on what E70 was, and at one point my wife told me it was low-pressure. It didn't sound right, or characteristic, for her to look that up- but I was content to believe it was our well pump pressure. Finally yesterday it happened 5 times.My wife asked if I could figure out what E70 was. I think that my speculation on what sort of error codes it might have may have convinced her that E70 had to do with water pressure. OK- so I look it up and found the solution. The HOT and COLD taps were swapped! Since the Cold water tap was insulated- the installer made the reasonable assumption that it was the hot tap. My bigger surprise was in how many people online had experienced the same error. I am sure that many washers don't flag an error for this sort of thing, so here's my advice- check that the hot and cold taps are correctly hooked up. We probably lost a lot of hot water, caused unnecessary fading of colors, and could have whiter whites if this had not happened. In fact- our new colored towels have faded surprisingly quickly.
