I have an amana front load washer nfw7200tw10 I replaced the drain pump and still get ND error
I had the same problem, not sure it was your pump, load it with a bucket of hot water and some bleach, turn it on and let it run through a short cycle, the hot water and bleach can clean the sensor and the screen in the bottom going down to the pump, did water drain out when you took the lines loose, if it did its a good sign, most people dont realize you use only a quarter or less cup of soap in this washer, it will get the sensor water sensor dirty and the washer thinks it has water when it doesnt, the pump cant drain cause there is no water, . try the hot water trick, rmember use a bucket and as hot a water as you can, probably hair sudds and who know what is blocking the sensor, mine was hair, from my little girl, Matt
