I normally use gel detergent in the dishwasher but some powder was on sale and I got that. Well my DS, 15, has to do the dishes and he grabbed the box of borax instead of the dish detergent. The worse part is I didn't figure it out until the third time he did it. The first time there was allot of powder in the dispensor after the cycle but I thought it was just because it was cheap. The dishes didn't get very clean. He broke up the leftover powder to reuse in the second load the following week. Then this week I told him to empty all the leftover out and start with fresh. Thats when I saw him take out the borax and start pouring it in. Well we cleaned it out and put the right stuff in but it came out the same. Powder left in and dishes that are not real clean. Is the washer ruined? There is no filter in this model that you can clean so I don't know what to do. Any suggestions?
