All, machine completed wash fine, went I went to use again the machine selects programs and panel lights up according to program and spin selected but the door lock just flashes permantely. Have took the door switch out the machine to bench test. It is a DM053 hoover part number 41016879. Have tested the continuity of the PTC and that is 1147ohms. Applied 240v to pins 1&3 and manually operated the mechanical side of the switch and pin 2 goes to 240v. Any one got any ideas what could be wrong? Any common faults with this machine. Thanks in advance

Many in the trade have come across this problem and odd though it may appear (apparently) changing the actual door cures the fault.
Yes, me neither :rolls: I’m just quoting what I’ve read.
But you’d best try a new Interlock first as they are far cheaper. 💡Re: Hoover VH W854 D washer dryer flashing door lock
cheers, the dor interlock seemed to pass function test when I bench tested it. Do wonder if putting a new one on will fix even though it seems to test out ok will give it a go. Could i suppose be an alignment issue so will have a play around with it whilst not actually in the chassis to see if it will play ball. Also guess I need to get meter out to check 240v to coil and when activated that the switched live makes it to where it needs to go on the pcb so no broken wires. Will report back with findings promise. Glad in a way that it appears to be a common issue. I actually have access to another machine just the 8kg model rather then 9kg but missus wont let me substitute parts. If it isnt something simple is the next bit the pcb can I interchange these to prove whats wrong? Did I read somewhere that new PCB’s come out unprogrammed so i need something to match it to the machine. Thanks
Re: Hoover VH W854 D washer dryer flashing door lock
all, not the interlock, and have metered the wiring back to the PCB and all fine. Have took the PCB out and one track is burnt out see attached pic it is the track at the bottom of the picture in the middle. On the other picture I have the meter probe indicating the track that is burnt connection to the multiblock, also in line is the blue component on the same picture this is open cct but not sure if it is a capacitor?
Re: Hoover VH W854 D washer dryer flashing door lock
Ok so the blue component is a MOV this is a protection circuit, I do not have an insulation tester to test that component with. Have looked at the wiring diagram for the PCB and it looks like the burnt track terminals head towards the pressure switch and the heater element for the dryer. Wonder if the insulation broke down on the heater and it spike backwards?
Re: Hoover VH W854 D washer dryer flashing door lock
My advice is to do a insulation check on machine with all the wires connected to the pcb and disconnect 1 component at the time until you find faulty component. Kai
