Hi, welcome to Just answer
Please tell me its complete model number and how old is it ?
IWD7145 UK type LB2006C FWMP5ICL 1400
OK as there is power to the door latch it seems fine
has it drained during the last cycle ?
if it has then the problem is with the control module that will need replacement
Yes. Once or twice the machine has come back and worked for a full wash and once seemed to get stuck in the middle of a wash and the on off button or st/pause button did not stop machine, had to unplug to stop
Ok then the problem is with the heating element not the control
If the problem is with the heating element would that result in no light on the machine as it is at the moment
It worked once or twice fine and then stuck in the middle...you can test the element for continuity, if it is fine then the control has to be replaced
