Hi my name is ***** ***** I will try and help your with this problem today.
The fact its still getting hot is a good sign, often the heating element is first to go.
In most cases the issues are due to a blockage, have you removed all the serviceable parts and given them a clean in hot soapy water? If it was run on empty you often find you get a build up of lime scale and coffee which blokes the tubes.
Secondly does it still make all the correct noises when you press for it to start?
In order to take this further could you also provide the specific model of Dualit, as this may help me guide you into further options to get it back running again.
Excellent, glad its working again.
I would appreciate if you could please rate the service you have received this week so I can close this case.
