I went to take a shower,and the water was lukewarm,even with the faucet

What could cause this? The heater is 2 years old,with a 6 year
warranty,but only the tank is covered for leakage.
You really haven't told enough to narrow things down, Herb. Like is the
water "warm" ONLY in the shower or at other locations too? That's a
biggie. If it's only the shower, chances are the shower valve is the
If the water is only "warm" everywhere else in the place then a likely
cause is that the "dip tube" which takes the cold water supply down to

Thanks for your input Jeff.
1. The water is warm at every HOT faucet in the house.
2. The hot water to the washer was fine yesterday. Plenty of hot water.
