sorry pal,needs a hot feed,only other solution is to buy a cold fill only washer.see the water is not in the drum long enough during cycles to heat up to correct temp.Well ideal temp,on the later models,the machine will just sit there heating the water,before it starts cycling.Yours doesn't it cycles through regardless,.Hence the washer washing with cold/tepid water.You must have both intakes connected to the water supply or theres a high chance of damaging the valve that isn't fed with water.
