yes espically if your hot water heater is on the opposite of the house. When turning on hot water only to the sink how long does it take for hot water to come?
Hello there If your dishwasher's cycle times are too long,
check these:Water
pre-heatingCycle
not completingWater pre-heatingYour dishwasher may pre-heat the water. If so, and
if the water entering the dishwasher is cool, the heater may take up to
half an hour to heat the water. To avoid the wait, increase the incoming water
temperature before turning on the dishwasher. Do that by running the
kitchen sink faucet until the water runs hot. Or increase the
temperature of the hot water to the entire house at the hot water
heater.Warning! To lessen the risk of scalding, don't set
the hot water heater temperature higher than 120 degrees Fahrenheit.
How far is your water heater from your dishwasher. I knew someone who had to get a circulating pump. His dishwasher was so far form the water heater so when the dishwasher would fill, it used the cold water that is sitting in the pipes and by the time the hot water got there, the dishwasher didn't need any more water. the pump will keep the water circulating back and forth to and from the hto water heater. Or you an get one of those electric small heaters that heat on the spot as well.
Generally speaking, dishwashers don't heat cold water on their own. Be sure the dishwasher is connected to a hot water supply and that hot water is available to the dishwasher at the START of the cycle.
Often it takes hot water several seconds for house plumbing to deliver hot water to an outlet. If the dishwasher is connected to the kitchen hot water supply, run the water in the sink until the water runs hot before you start the dishwasher.
Dishwashers often have heaters to heat the water even hotter than most home water heaters, but they are not intended to heat cool or cold water. You MUST furnish hot water to the dishwasher from the time the cycle is started.
I've seen houses that take so long for hot water to reach a faucet, the dishwasher is already full (of cold water) before the first drop of hot water reaches it.
If this dishwasher is a residential dishwasher the water that is supplied to the unit is from the hot water side of the sink supply. The dishwasher does not heat the water it uses water from the water heater that is connected to the house. It sounds as if the dishwasher is hooked up to the cold water supply instead of the hot water supply. The heating element you see in the dishwasher is for drying purposes and not for heating water. I would check the hot water supply for your dishwasher to see if that could be the problem. Also remember unless you have a recirculating pump on the hot water there will be an amount of water in the pipe from the water heater and the dishwasher that has sat and cooled down over a period of time therefore when you turn on the dishwasher you will not get hot water immediately due to the distance the dishwasher is from the water heater. You will notice when you turn on the hot water to thew sink you do not get hot water right away you let it run for a minute before it gets hot since the dishwasher is connected to the same valve as your hot water to the sink it acts the same way.
Good luck on your repairs hope this helped.
