[Solved] Bosch 20460 Washing Machine - F16 Error: Door Lock Issues Despite Successful Coil Resistance Test

Hello,
My washing machine just got error F16. When I turn on the washing machine after 60 seconds, F16 pops up on the display - the door is not locked. When I open and close the door a second / third time more vigorously, the washing machine moves and the lock locks and the laundry functions normally.

I dismantled the lock to check the connections for loose ends, dismantled the lock, I measured the coil resistance and it's ok, unfortunately the problem remained as if it didn't catch the first time / stuck somewhere. What else can I diagnose to make sure the lock needs to be replaced?

If I understand correctly, it should work like this:
- the bolt mechanically engages the contacts of the low-current circuit
- The controller, receiving the information about the closed circuit, puts out the voltage
on the electromagnet power circuit and the door is locked.


P.S.
I noticed that there are two types of locks on sale:
603514 (on the so-called click in the housing) and I have one
182154 (for screws) much cheaper
According to the photos, they differ only in the way they are attached (which is basically removable and can be moved). The question is has anyone tried this procedure?

Hello.
I think the problem is the bolt itself, which does not close the circuit every time, so the coil does not get voltage. The end of the bolt may be worn, need to be adjusted or replaced.

Problem solved - I'll answer myself partly for "posterity"

The lock works:
- the module, after starting, gives a voltage of ~230 to pins 2-3
- after about 6 seconds (thermocouple heating up) circuit 2-1 and mechanically locked lock are activated.

The blockade is completely removable (enclosures are latched) the manufacturer is an Italian company ROLD Group - DM series blockade model DM 070
The blockade works on the principle of "thermomechanical" switching on the circuit (it is possible to adjust the operation using a copper screw available in the body.

PS> after disassembling the lock into its first parts and reassembling - the lock works properly / probably the mechanism has hung up.

I fixed it!!! Thank you very much for the advice. 2 hours of work for a novice, I undressed and pokmerał and bingo. Thanks again for the advice
