DEDW645 Series

My delonghi DEDW645 came up with error code E4 one day, went through the empty water process, and it came good for a while, now it will only run on normal cycle which takes nearly 3hrs! Every other cycle will start but error on E4 again. Not happy, can anyone please shed any light on my issue at all please? Thanks. BTW, I have clean filters and no water leaks and water pressure is acceptable.

Thank you. I have checked all these and no issues. Only thing I can think of now is the box on the water inlet hose is faulty

Why is water not hot ?

2 answers

Because the heating element is rubbish. We had to connect to a hot water tap to get the dishwasher to an acceptable steaming temperature.

Furthermore, please wash dishes at Heavy or Intensive wash cycles, press the options button until top light for drying tops up.

My dishwasher is washing in cold water not in hot has just started doing this in past few days has been fine up till now nothing has changed it hasn’t been moved or anything , bought it in September 2016, would it be covered under warranty

Should still be covered under warranty. Sounds like your heating element has gone, that's what happened to mine. You need to contact DeLonghi for a service contractor in your area, asap don't waste anytime because your warranty might run out, anyway I think the warranty might be only two years, check your documents!

Barb

Thank you I have got a 5 year warranty so should be okay

are you pressing the timer by mistake? this starts the dishwasher in delay mode and counts the hours before it starts at the selected time/hour.

Hi, is the water getting hot when it is running? If not I would say it's your heating element. Ours did that when the heating element went the first time. But also does that now but unsure why at this stage.

I'm sorry I am not sure we had it replaced under warranty so the specialist did the work.

since you are wanting to take the punt, you might as well open it all up and see where it goes, make a video doing this so you remember the sequence of putting back together.

The heat comes from inside machine eg heating element. Hate to say it i think your heater inside dishwasher is gone. Warranty should cover this.

What is the best way to add salt? Do I just put it straight into the bottom of the cabinet and then run the Quick Wash cycle?
