How can I stop the open door bell to stop

I don't think you can turn off the chime noise. It should sound about 3 or 4 times at the end of the cycle and then go quiet.

Dishwasher not heating up water properly, so not washing and leaving behind fat residues on items and spray and collection points.

Hi, have you run dishwasher cleaner through the machine and cleaned the filter. If this doesn't work you will need to call an engineer.

I can no longer select different programmes. I usually use the one hour program, when I push the program button it remains on the ‘normal’ setting. Any idea how I can rectify this?

Not sure. The menu doesn't appear on the screen only the time for the cycle that then counts down as the cycle heads towards completion

Not working at all. Getting a error message that counts up from H01 to H24 then repeats.
H01, H02,.....H23, H24, H01......

Buttons light up but none responding. Makes starting ping noise when turned on.

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
