Hi Guys
Can anyone shed a light on how to bypass a door interlock(if it possible) for testing or making a test kit?
Also what is the best way to test the door interlock apart from putting it in another machine?
Best Regards
Re: Testing or Bypassing Door Interlock
It all depends on the type of lock, you have to ascertain which connections are the switching circuit or it goes bang 😳 usually the timer/programmer, PCB 😯
A wire link with male spade connectors comes in handy. 😉
probably best left alone if you are not sure 😥
Re: Testing or Bypassing Door Interlock
Usually theres a feed a neutral & a switchwire, you have to link the feed & switchwire. Unfortunately you can get it wrong & bang! 😯
Re: Testing or Bypassing Door Interlock
depends on lock but most you connect live to common, not live to neutral it will go bang be careful (i hope this is just for testing purpose’s 😯
Re: Testing or Bypassing Door Interlock
Most door interlocks are marked with L, C and N or on older appliances maybe 1, 2 and 3 which generally relate to 1 = N, 2 = C and 3 = L but only as a general rule of thumb. If they are marked as L, N and C then short L to C. (Live to common) If I want a quick test then I use my insulated pointed nose pliers (I can hear the ‘tut tutting’ from our more safety conscious engineers as I typed that! Quite rightly so) But a typical fault on any WM Hotpoint series is that the door lock was originally the fault and you bypass the door lock to confirm it but after fitting a new one it still doesn’t work. This is because the fault has probably been on the heater coil of the lock and blown tracks off the timer P.C.B. Normally easy to re-solder. Now to put the cat amongst the pigeons! The labour charge goes up if you have to attempt the soldering job and they pay for a new door lock but I explain the situation to the customer and a quick cheap job is to put a link between the two terminals explaining that the door won’t lock, the door can be opened at any time during the cycle and if the door is open when the cycle is set then it will flood. If that suits them (and I put that on the job sheet with their signature) then that’s what I do. A legal boffin has told me that the machine has to be sold with safety devises fitted but after warranty and in your own home then the rest is up to the customer.
Your comments please !

Sorry Jim but isn’t that what this confidential site is all about?
Paul.Re: Testing or Bypassing Door Interlock
If the customer opens the door and scalds her young child who just happens to be crawling along the floor at the time, or puts their little arm inside whist it is on spin, you will need a lot more than your legal boffin to get you out of the brown stuff. Don’t do it. it is just not worth the risk. I would give them a bloody door lock or leave the machine unrepaired before I would do this. It only takes 5 minutes to solder the timer tracks FGS.

What!!! How can you sleep at nights?
I can’t believe that anyone on this site would deliberately leave a machine with a disabled door lock.
Practices like this are totally unacceptable in my book. You should be ashamed of yourself!

Re: Testing or Bypassing Door Interlock
i still repair those pcbs by drilling a couple of hole and resoldering a piece of link wire never go’s again 😆
Re: Testing or Bypassing Door Interlock
I’ve seen this a few times and it scares the shit out of me, how anybody can be so silly is beyond me, i was called to a machine which sombedy about lost their hand due this practice, trouble was it wasnt the numpty who did it who had to go and inspect it, the cust tried make a claim against the Manufacturer claiming it was faulty manufacture, needless to say old numpty head got sued and went bust.

hows this for a new name

bad pratice mate.. there is a serious risk of litigation with or without customers signiture if this common pratice
do you give warranty with your work???
I sleep at night and have no worries of a white enverlope arriving
with Norfolk & Hope franked on it because some child has been maimed for life with very hot water burns..due to pure incompetenace.after all whats the cost of a interlock
this thread might run for a long time..I hope you are good at taking on board valuable and sensible advice

Re: Testing or Bypassing Door Interlock
i only by-pass for my own testing purpose”s anyone who leave’s a machine without a working lock is mad. anyway is it really your problem if her machine needs a new lock and you have to order one surely they can wait a few days!!!
Re: Testing or Bypassing Door Interlock
Cat amongst the pigeons was obviously an under statement! I do take all I can on board when I go to a call i.e. toddlers, low income, single parent etc so if that is the case then I just give them the full quote for the repair and don’t even tell them about a by-pass. BUT if all they’ve got is a couple of cats and the machine is in a garage or something then I give them the option. Especially if it is getting someone out of a financial tight corner. I know I might be sounding a bit ‘self righteous’ here but so far the only comments have been against what I have been known to do in the past but I bet I am not the only one to have done this. By the way, 30 years in the trade and not one come back on the above. (I did get 7 recalls on snails up the waste pipe!)
Come on, be honest, has nobody out there ever done the same? However I do respect your comments.
