Hi.
If there is power then the door switch is probably broken. first make sure that there is power to the machine. The door switch is tested with power off, accessing switch contacts and reading Ohms with a multimeter. When door is closed the switch must have continuity, reading zero or few Ohms. With door open the switch contacts read infinity (circuit open).
If the door switch is OK, test power cord, main switch, wiring harness, motor and timer.

I know.
If you repair appliances you know how troubleshooting works. You test things in order.
After Ohming door switch you check VAC at the on off switch, have a look at the thermal fuse if this is in line with the motor (check continuity), check volts at timer etc. I expected a clarification request. I got a bad feedback even if I did not say anything wrong...happens.
Unfortunately you have passed the question to another expert. Someone else will help you.
Good luck and Goodbye.

Hi I believe that everything else is fine rather it is the
thermal fuse that is located inside the rear panel to the exhaust duct that is
bad and should be replaced. If you want you can test this fuse for continuity
and if it is bad then it should be replaced, as it cannot be reset. If the fuse
is fine then it can be due to the control board that is bad and should be
replaced. Hope this helps...please post back for further assistance. Daniel
Check to see if the switch on the door jamb operates correctly. It works just like a wall light switch in your home. With an ohm meter you can check it or just jump the two switch wires together and see if it starts up. You must be careful if testing this way

I have tried all the normal tests, switch wiring continuity door catch etc, they are ok. there is no response when power is on to the machine.no programme lights nothing.I repair central heating boilers for a living I have a good idea what i'm doing. The hotpoint service dept said it sounded like the interface pcb i've changed that no different
As i've said previously I have carried out all the normal tests the door switch was one of the first it isn't that
