DISWASHER hdw100wht WE ARE REPLACING OUR OLD DISHWASHER WHICH IS CONNECTED TO A HOT WATER TAP, CAN WE CONNECT THE HAIER TO THE HOT WATER SUPPLY AS THERE IS NO COLD WATER CONNECTION?.

OK. When you see water on the floor, and you open the door, is there any water rising in the wash chamber and breaching the seal? If you open the door and do not see any water other than the water dripping off the dishes or whatever, I would suspect there's a leak underneath. If you see water standing in there, they you will want to clean the food/debris trap. Refer to your manual, if you have one. If the food trap is cleared and the water is still comin out, I would suspect a leak underneath the unit, possibly a loose water hose or drain hose.

Hi.
Your dishwasher should never be connected to a hot water tap.
Every dishwasher has its own Heating element. If you connect it to a hot water tap you may eventually damage the inlet valve which has sensitive plastic components in it and may even void your warranty if your installation manual suggests Cold water connection only.

Hello. The water coming into a dishwasher is from the hot water supply line nearby, often under the sink. Make sure that the valve on that dishwasher supply line is opened all the way. Turn it counter clockwise as far as it will go. If that does not solve your problem, consider replacing the dishwasher hot water supply line. The old line may be bent or partially clogged with sediment. J.

You'll have to tap into the hot water supply for the sink to get a connection for the dishwasher. This is a moderatley difficult plumbing task. If you don't have plumbing experience, it's probably best to call a plumber.

If you want to do this yourself, let me know and I'll try to help.

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.

Good luck. Hope this helps.

When you run the hot water at the kitchen sink until it is hot and start a cycle on your dishwasher, is water hot when you open the door after it stops filling?
If no, the diswasher is connected to the cold water line, not the hot water line. The water temerature entering should be a minimum of 120 degrees but no hotter than 140 degrees.
If the water going in is hot, but it cools down after each filling then the heating element has failed and needs to be replaced. When the heating element fails, the dishes, especially the glassware will be foggy and still dirty.
Please reply with what you find. Good Luck!

In my opinion you always connect to the hot water unless there's some compelling reason not to like your dishwasher's manual says to connect to cold. Your dishwasher will heat up whatever water you have connected it to, but since you have a tank of preheated water already sitting in your water heater you should use that.

The "resin in the water softener" example, I think, makes no sense since your dishwasher will heat up the water to something like 160 degrees Fahrenheit no matter if the input is cold or hot...

your water heater is set too low in temp.
you can turn up the heat or get an on demand heater under your sink for the dishwasher. you get a tax rebate too.
the heater in the new washers are too small to effectively heat the water to hot.
and always add a bit of bleach to your wash. the hot water will neutralize it.
or get an old dishwasher.
