    Hello.
    There is this problem with a central hoover in a detached house. Sometimes it wants to start by itself. It is also triggered by turning on e.g. a light. The cables from the control contacts in the sockets are ok. I have also checked with an inductor to see if there is a puncture from the electrical system. Could it be induction from electrical cables running too close? When I switched off the electricity throughout the house at the fuses outside in the box and applied voltage from an extension cord connected to a neighbouring house everything was ok. All I had to do was switch on the fuses and the hoover started trying to start again. I should add that the box where the control wires converge and the hoover itself are mounted right next to the electrical distributor inside the house.

    Perhaps blocking the wires from the control module with a capacitor of say 100nF would help ?

    Switch between the wires of the control cable?

    This is what I would do. Check what the voltages are still there. My guess is 5-12V
