Thank you for responding Bernii, I don't know what I have done but the machine now works??( has done for the past week!!) I remedied a definite Kink in the inlet pipe when I pulled the machine out to investigate your suggestions..so..maybe that was it:) I do hope so! Should the fault occur again I will try some of your more in-depth remedial actions. Thank you so, so much once again for bothering to respond, best wishes.
