John Lewis JLDWW1205 not heating up

As soon as the wash cycle is complete open the door, are the dishes hot and steaming? If not one of 2 things is possible, one you have the hot dry option setting turned off, the other the heating element at the bottom of the dishwasher is burned out.

The dishwasher does not dry the dishes, it is the residual heat remaining from the washing water that dries the dishes.
Once the washing cycle is over, opening the door and pulling the top drawer out slightly to keep the door ajar will create a small opening which allows the steam to escape and the dishes then dry a lot quicker.

all the lights will be on before you select a cycle, if the Rinse Aid and Salt warning indicator lights are on you need to add rinse and salt to the appropriate fill up locations

Make sure you have the heated dry setting selected, use rinse aid at all times, and make sure the unit is getting hot. If it is not, or there is no steam generated when you open the unit after cycle - have a professional diagnose the heating element.

• Well, the dishes inside the dishwasher will still be wet unless you use a dry cycle at the end of the washing cycle. Not all dishwashers have this option. Even though mine does I rarely use it as the dishes will dry on their own in two hours.Saves a little money. Even when washing on a normal cycle the dishwasher itself should not get hot. It may blow a little steam out the front vent. Hope this helps.

Hi -
I can't see how any installation problem would cause this - if the dishes are still wet at the end of the cycle, you'll probably find the water isn't heating during the wash cycle. The dishwasher uses steam to heat the washing compartment and dry the dishes. It would appear that the dishwasher isn't heating water internally.
Even if the washer was accidentally connected to the cold water supply ** (see note), this shouldn't happen as regardless of the water supply temperature, the washer should still heat the water to the correct temperature internally.
** UK dishwashers should be connected to the cold water supply. For US installations, dishwashers are commonly connected to the hot water supply. For other locations, please consult your installation instructions.
I suggest you start a regular wash cycle and leave it to run for 10-15 minutes. Then open the door and test the temperature of the water in the base of the washer by hand. The water should be hot and there should be steam present in the washer when you open the door.
If the water is cold or only warm, the water isn't being heated internally or isn't heating to the correct temperature, in which case you should contact the retailer or Bosch Service immediately for a replacement. Do not accept an offer of repair on a brand new washer!
Additionally, do not attempt to repair the dishwasher yourself when under warrantly as this will invalidate the warranty.
Hope this helps. If you need further assistance, please let me know your location and the model number of the washer. This should be laser-etched into the top of the door if you can't find it on any of your paperwork.

Choose the hottest rinse cycle first Economy cycles don't work properly Make sure you have rinse aid in the dispenser. Make sure the machine is heating properly too. An aid do drying is to open the door of the dishwasher just when the cycle finishes steam should come out and the water in the cabinet will condense to the walls and dry the dishes. some top end models do this with a push rod..... believe it or not (Miele) go to my website for a detailed explanation about drying www.appliances.cjb.net you can contact me from there too for further follow up good luck

sounds like your heating element is not working prtoperly or you are not washing in very hot water stop washer in middle of cycle and open it if steam come out hot steam be careful keep face away when you open itif not hot that could be the problem,A appliance serviceman once told me if water is hot enough and end of wash and rinse cycle not to run the dry cyvcle just open dryer a few inches and let the steam out Run hot water over a plate or a pot and set it in the drain tray in your sink notice how fast it dries itself while draining in the tray very hot water in a dish washer dopes the same good luck with this problem I hope my advice helps you oh yes one more thing always run the hot water till it get hot before you turn your dishwasher on

You dont really need it, when the washer gets done Open the door for a minute and let the steam out and shut the door dishes will then dry. the reason there still wet is because of the steam from the Hot water

Hi, Most dishwashers do not have steam vents! there are several reasons for poor drying in a d/washer! The first one is to see that you have rinse aid in the machine as this aids drying! Next if you have rinse aid then is it being put into the machine when it needs it? Also you must bear in mind that the dishwasher need to heat on the last rinse to create the heat to dry the items which use the steam to dry them. Check the rinse aid first and see how you get on....
Let me know.......
