Installing a built-in LG dishwasher; got everything ready to go, but a problem with the hot water line coming in. It is barely long enough to reach to the front where I've installed the elbow. Since I have to back the dishwasher in to the 24 in. hole there is no room for error in terms of not running over this hose with the bottom of the dishwasher. Any tricks to handling this situation?

Does any water come out of the faucet when turned to hot? If not, you may have disconnected the fautet line from the valve and attached the dishwasher line. You can check this by looking under the sink and making sure all lines are connected to valves.

If everything is connected, you may have dislodged some mineral buildup and it is blocking your hot water line to the faucet. You'll have to remove the line and clean it out.

Hot water is introduced into the dishwasher from your regular hot water lines. If you are not getting hot water at your sink, that could be part of the problem. If the water in the machine is warm, you are getting feed from your house boiler, but the instant hot water coils in the dishwasher are not working. There may be a fuse panel for the coils that can be checked or, if not it is a wiring problem to the heat coils or the coils themselves burnt out.

Hello,

Welcome to FixYa.

Have you insured the unit is connected to a hot water supply line ? The water will not heat until it start's to circulate and activates the "flow switch" in the Bosch dishwashers.

If it is connected to a hot water supply, try running the hot water at your sink taps before turning on the dishwasher. If you still do not have hot water, check your hot water heater or supply.

If it is indeed connected to a cold water supply it will work, just be prepared for very long wash cycles since the Bosch machines will heat the water at a rate of 2F per minute...it could take a long time to reach 155F.

Let me know what you find out and I'll try to assist you in any manner I can going forward.

Is the water around 130 F, if so make sure you run the water at your sink till the line fills with hot water before starting the machine. Make sure your getting enough water and that the spray arms are turning and clean.

Your not getting enough water into the unit,when filled the water should just touch the bottom of the heater.If it's not,take the water line loose and make sure it's not clogged,you can also remove the valve and try either cleaning it out or replacing it part number is 6-920534 sells for about $30 but make sure you have good pressure coming to the unit before replacing it.

I eventually unhooked the hotwater line where it comes in below the sink in order to give the slack I needed to hook it up to the elbow on the front of the dishwasher...then slid it into the 24in. space, but found that my hotwater line was 4 inches short! A trip to home Home Dept to buy more line and connectors solved the trick and now it is all hooked up and works with no leaks.

Dishwashers do have a water heater element. In fact, it's the same heater that is used for hot dry, but you can switch it off for the drying cycle if you want. Dishwashers heat the water so it will be hot enough to properly clean the dishes. Sorry, you lose the bet.

Generally there are three items to be addressed:  You will need power.  This should be a separate line appropriately protected...usually 15 or 20 amps, depending on wire size serving the unit.  You will need a hot water line which attaches to a fitting under the machine.  You will need a fitting to drain the water to the drain line.  If you're going to permanently install, you should have a fitting to do this on the drain line of the sink.  It is generally included with the machine.  If you have a disposer on the drain, a knockout plug on the dishwasher will allow you to install it.  If this information is insufficient, I suggest you get service help to do this.

There is no heater element in bosh D/W
Problaby, your hot water is not hot enough and I don't know nobody in your area.Your water heater in your home should be set at 120-140 degrees, read the book to make sure.

Does it a brand new dishwasher ?
