Does the WM65 have a heating element and would you recommend using direct hot and cold or just cold?

Yes its fine. Most washers only have a cold feed anyway. But if yours as hot and cold the washer will heat it up

Hi Charles
The traditional method of supply was using hot water for filling. However, it is possible to save money on some machines by hooking up to cold water as the element in the dishwasher uses less power than your water heater. Unfortunately, some manufacturers still require using hot water for filling. You'll need to check your manual to see if this is the case. Here's a link to This Old House explaining dishwasher installation.
Hope this helps

How to Install Dishwasher

Ensure the hose's at the back are in the right places, Could be you or the fitters has put them in the wrong place.

Hi from retired Englishman in SW France,

In a word- YES!

You will need to purchase, from a hardware (?) store, a 'Y' adapter. Upside down the single end screws into the cold water supply and the hot and cold washer pipes screw into the double end. The washer is fooled into thinking it has hot and cold! When it expects hot, it opens its hot valve but instead gets the cold water and has to heat it up. It will therefore take longer for the machine to do the washing. When it wants cold for rinses, it opens its cold valve and gets the same water! Simple ;-0)
Good luck,
John C

Hi from retired Englishman in France (it's 21:29!),

If your washer has 2 pipes for feeding water then one is for hot and the other is for cold naturally.
All washing machines have a water heating element in them- in case any hot water supply is not hot enough for its wash.
If you only have a cold tap you will need to purchase a 'Y' connector. This screws onto the cold tap supply (single end) and the hot and cold feed pipes connected to the washer screw onto the other two ends. The machine will now be fooled into thinking it has two separate feeds!
The machine opens the valve for the 'hot' water supply (which of course is cold) and the heats it up to the required temperature for the wash cycle. Afterwards, when the machine requires cold water for rinsing, it opens up the 'cold' supply (which is the same supply as for the hot water!) and is happy.

Hope this answers your question.

Connect the dishwasher to the HOT water side. Although most dishwashers have a heating element to heat the water, they are normally installed this way to reduce the amount of time the heating element is on. This not only extends the life of the heating element, but also reduces the amount of electricity required to heat the water. Another helpful hint: Before you run the dishwasher, run the hot water tap until the water runs hot. This will fill the dishwasher with water that is already hot instead of the cold water that normally sits in the line after the hot water has not been run for a while. If you have questions, please let me know. I hope this helps you.

These machines are designed to have the cold water around 70-75 degrees. If your cold water is colder than that it will automatically mix in hot during the wash cycle to reach that temperature. It all has to do with the optimum temp for proper detergent function.

All Hotpoint washers have heater element regardless of whether they are cold fill only, or hot and cold fill.
if 2 connections at rear, then it is hot and cold fill, if only 1 connection, then it is cold fill only.
Please rate my solution.
Thanks.

Hello,

You can use the cold water only with no issues at all. The only thing you will have to do is buy a cap to block off the hot water inlet on the back of the machine otherwise the cold water will flow out through it onto your floor etc.

And yes, your machine has an element built in which will heat the water for you!

Washers are meant to rinse in cold water, so clothes should come out cold.
If you are not sure if it is getting hot, then select a very hot wash, and feel the door glass periodically, it should gradually get hotter, if it does not , then it is washing in cold water only.
This could mean that the heater element has gone.
Plz rate my solution.
Thanks.
