Hobart WM-ID dishwasher doesn't heat water enough to clean dishes

am14 is not an under counter. Please specify what you have and is the issue is with wash or rinse heat.

If you open the door immediately after the dishes are washed, and before the "dry" cycle, is the water hot enough to have "steam" coming out of the machine?
You should be able to feel the heat.
If not, perhaps the water is not getting hot enough to dissolve the dishwashing powder.
Could you try using a liquid soap once and see what happens?
Be blessed.

Hello

Water Inlet Valve

A dishwasher's water inlet valve is its most common part to fail. When your dishes are not being fully cleaned, quite often a faulty water inlet valve is to blame. Test your dishwasher's water inlet valve, and if it is no longer functioning as it should, you will have to replace it.

Upper or Lower Spray Arm


Your dishwasher has a lower spray arm. It may also have an upper spray arm at the top of the dishwasher. These spray arms are designed to shoot high pressure, high temperature water at your dishes. It is possible that the holes of the spray arms, where the water comes out, are blocked with debris, affecting wash quality. You should inspect your dishwasher's spray arms regularly. Clean out the spray arms as need be.

Heating Element

Water temperature is a key element in achieving clean dishes. A dishwasher's heating element is not designed to heat the water that enters it. Rather, the heating element is designed to maintain the heat of the water that enters the dishwasher. Its a good idea to run the hot water in your sink for a couple of minutes before you run the dishwasher. Just to make sure the water is nice and hot before it enters the dishwasher. If the water is unable to stay hot, it can adversely affect your dishwasher's cleaning ability.


Filter/Drain Grate

There is a filter in your dishwasher. Its function is to keep large particles of food and foreign objects away from the pump. Many of the newly-manufactured dishwashers have self-cleaning filters, and routine cleaning isn't a concern. However, some other dishw ashers need to have the filter removed and cleaned regularly. If the filter or grate is clogged or blocked with debris, it may interfere with the normal functioning of your dishwasher. Consult your owner's manual for specific directions for removing your dishwasher's filter and cleaning it.

Detergent or Detergent Cup

It could just be that you aren't using enough soap to completely wash your dishes. Your dishwasher may be designed to dispense soap at two different times during the wash cycle. If you don't fill all of the detergent cups, then the diswasher will lose a cleaning cycle. Also, if you use a gel-type detergent, try switching to a powered kind. Powders tend to dissolve better in hot water. And don't buy in bulk. Detergents are most effective in the first two weeks. After that, they decrease in potency.

Alternatively, your dishwasher's detergent cup could be defective in some way. It is possible that it is gunked up full of built up detergent, and a thorough cleaning may be enough to get it working again. If that doesn't do the trick, you probably need to replace the entire detergent cup assembly. If your cup isn't even opening, please see our section My dishwasher detergent cup won't open.

I was wondering the same thing. This is what I found:

The display shows "HO" or "Hd." What does this mean?
HO" or "Hd" means the dishwasher's cycle time is being extended while it is heating water. At certain points in the wash cycle, the dishwasher uses hotter water to ensure a clean load of dishes. If it detects that the water is not hot enough, it will heat it.

If you're seeing "HO" or "Hd" frequently, check the temperature of the water available to your dishwasher. It's best to do this at the sink closest to it, allowing the hot water to run until it reaches its maximum temperature before you test it with a thermometer. For best results, water should be not less than 120°F.

Most dishwashers require a minimum 120 degree inlet water temp. The heating element will boost this up during the main wash cycle to aprox 140. Do not hook a dishwasher up to inlet water temps above 150.

your heating coil has gone bad it`s that rod looking thing in the bottom of your unit under your spray washing spinner depending on the age of your unit your probley better off buying a new dishwasher

Heater is used to both heat water during clean cycle and dry dishes after wash cycle. Most washers have either a separate switch for Heat or Dry for optional use, or some have the water heat and dish dry options built into cycle set options.

You can save money by turning off the Dish Dry option since it is a very in-efficient way to dry dishes. Instead, open the wishwasher door after washing cycle completes, just enough so fresh air can get into, and humid air can escape, dishwasher.

Water Heat option is only needed for dried food on dishes, and is never needed if dishes are either rised off before putting them in the dishwasher, or rinsed off inside the dishwaser with a Rinse cycle, if they are to stand for a time waiting for a full dishwasher for wash.

generally dishwashers rely on the pressure supplied by the water supply line. check to see if it is enough or if inlet pipe is of sufficient diameter for needed flow.in some instances i know of seperate lines needing to be run directly instead of coming off of supply to sink area.

momrules, it could vary depending on the water entering the dishwasher. On a heavy cycle normal time is about 85 minutes not including thermal holds ( pauses that heat the water). On a normal wash, 68 to 75 minutes not including thermal holds. If the water entering the dishwasher is not at least 120 to 140 degrees the dishwasher will pause in cycles to heat the water before advancing. So 120 minutes is not unrealistic. The heaters in the dishwasher are low wattage and will only heat the water approx. 2 degrees every 5 minutes. Catriver.
