On the warm setting only get cold water. on the hot setting i do get hot water. please help

You might not be able to do much about this. It seems most manufacturer are concerned with reducing energy usage on washers. To that end, the biggest user of energy for a washer is not the motor, but the energy used to heat your water. Reducing the temp's will allow them to lower the energy used rating.
As an example, let's say you measure your cold water at a faucet and it's 55 degrees (of course this varies with the part of the country you live in. It is basically the average year round temp. Here where I am in Minnesota, that's about 44, but in Texas or Florida, it might be close to 70) Measure the hot at your faucet also, and let's say you get 125.
Now, if you measure the incomming water on your washer, the cold might be close to the cold measured at the faucet, say 60 in your area, but the warm might only be 70. Maybe not enough of a difference that your hand would even notice. Checking the hot, you might see not much over 100.
As I've said, the energy guidlines your government set forth are driving companies to make these type of adjustments. There is not much you can do about it short of re-wirering and possibly replacing the multi selenoid thermostatically controled water valve to make it into an older style washer fill system. The temp settings now are actually set to deliver temps which more accurately hit the ranges clothing manufacturers want when they say COLD, or WARM wash, in spite of your incomming water temps to the machine.
